As a Chinese enterprise engaged in the cross-border business of AB glue, we deeply understand that navigating the latest U.S. policy restrictions and ensuring maritime shipping compliance are crucial to avoiding operational risks, such as cargo detention, fines, market access bans, and delivery delays. AB glue, a high-adhesion composite adhesive widely used in industrial manufacturing, electronic assembly, construction, automobile maintenance, and household repairs, is favored for its strong bonding force, fast curing speed, and wide applicability to various materials. Due to its chemical composition that may contain flammable, corrosive, or potentially harmful substances, AB glue imported from China is subject to stringent regulatory scrutiny in the U.S. market. In 2025-2026, the U.S. government, along with federal agencies including the Environmental Protection Agency (EPA), Customs and Border Protection (CBP), Department of Commerce, Occupational Safety and Health Administration (OSHA), and Food and Drug Administration (FDA), has intensified regulatory enforcement on imported Chinese AB glue, updating policies covering tariffs, chemical restrictions, safety certification standards, and labeling requirements. Below are two key summaries of the latest U.S. policy restrictions and the additional precautions that cross-border AB glue enterprises must take when shipping by sea, designed to help peers reduce compliance risks and ensure smooth order delivery.
1. Comply with the Latest U.S. Policy Restrictions on Chinese AB Glue
The U.S. imposes strict federal and state-level policy restrictions on imported Chinese AB glue, with significant updates in 2025-2026 that directly affect cross-border operational costs and market access. AB glue has diverse specifications—varying in chemical composition (epoxy resin, acrylic, polyurethane, etc.), curing type (fast-curing, slow-curing), adhesion strength, and application scenarios (industrial-grade, food-contact, medical-grade)—which lead to tailored regulatory requirements. Enterprises must fully grasp these restrictions and strictly comply with them to avoid irreversible losses. The latest U.S. policy restrictions on Chinese AB glue mainly focus on tariff policies, chemical restrictions (including harmful substances and prohibited additives), safety certification standards, and labeling requirements.
First, tariff policies and classification rules have become more rigorous, increasing export costs significantly. Pursuant to the U.S. Harmonized Tariff Schedule (HTS) 2025 Revision 32 (effective December 5, 2025) and updates from the U.S. Trade Representative Office (USTR), Chinese-origin AB glue is primarily classified under HTS 3506 (for adhesives based on polymers or resinoids) and HTS 3208 (for other adhesives containing organic solvents), with specific 8-digit subcodes determined by chemical composition, curing mechanism, and application. For example, epoxy AB glue for general industrial use is classified under HTS 35061000, while acrylic AB glue with organic solvents falls under HTS 32081000. The Most-Favored-Nation (MFN) duty rate for AB glue ranges from 5.1% to 10.3% depending on the product type and chemical composition, and critically, they remain subject to the 10% additional Section 301 tariff, resulting in a total combined tariff rate of 15.1% to 20.3%. Importantly, AB glue is not included in the 178 product categories eligible for the Section 301 tariff exemption extension (announced by USTR on November 26, 2025, extending through November 10, 2026), meaning all Chinese-origin AB glue must pay the full additional tariff with no exceptions.
Notably, the de minimis tariff exemption for Chinese-origin products valued at $800 or less has been completely eliminated since August 29, 2025, per CBP announcement issued on August 15, 2025, in accordance with Executive Order 14324. This policy directly impacts AB glue shipments: due to its high unit value and bulk order requirements (especially for industrial bulk orders), even small batches (usually 100-500 sets of standard-sized AB glue) easily exceed $800, forcing all commercial consignments to undergo formal customs clearance and pay applicable tariffs. From August 29, 2025, to February 28, 2026, enterprises can choose either the ad valorem tariff method or the specific tariff method for tax calculation, but they can only select one method per month; after February 28, 2026, all AB glue shipments to the U.S. via international postal networks must use the ad valorem tariff method, which calculates tariffs based on the effective IEEPA tariff rate of the country of origin—for Chinese products, this is 10% reciprocal tariff plus 20% basic tariff, in addition to the existing 10% Section 301 tariff. Tariffs must be paid by the 7th working day of the month following the customs declaration month; late payment will incur fines of 0.05% of the goods’ value per day. Additionally, all postal items containing AB glue valued at or under $800 are subject to a duty rate of either 30% of their value or $25 per item (increasing to $50 per item after June 1, 2025), replacing any other duties.
Any shipment valued over $2,500 still requires formal customs declaration, and AB glue subject to anti-dumping/countervailing duties, quotas, or ineligible for de minimis exemption are not covered by any temporary preferential policies. CBP has intensified audits on tariff classification of AB glue in 2026, requiring detailed product descriptions specifying chemical composition (e.g., epoxy resin, acrylic), curing type (e.g., fast-curing, UV-curing), adhesion strength (e.g., 20 MPa, 30 MPa), product type (e.g., industrial-grade AB glue, food-contact AB glue), and application scenario (e.g., electronic assembly, automobile maintenance, food packaging sealing) to support proper HTS coding. CBP has also emphasized that vague product descriptions such as “AB Glue” or “Adhesive” are no longer acceptable and will result in declaration rejection or detention. Misclassification leads to backdated duty payments, fines of up to 100% of the goods’ value, and potential shipment detention. Additionally, Executive Orders 14358 and related updates (effective November 2025) reaffirm the 10% Section 301 tariff on Chinese industrial raw materials and finished products, including AB glue, with no indication of near-term reductions. Furthermore, imported AB glue is subject to the 9% import value-added tax rate, which enterprises must factor into cost calculations. It is also worth noting that U.S. tariff increase plans have been extended to January 1, 2027, giving Chinese AB glue cross-border enterprises a 12-month adjustment window, but compliance with current policies remains the top priority.
Second, chemical restrictions, especially on harmful substances and prohibited additives, have become increasingly strict at both federal and state levels, directly affecting AB glue production and export. AB glue, especially those made of epoxy resin, acrylic, or polyurethane, may contain trace amounts of harmful substances (lead, cadmium, mercury, arsenic, formaldehyde, benzene) and prohibited additives (phthalates, PFAS, polybrominated diphenyl ethers, volatile organic compounds (VOCs)) in the production process, which can pose risks to human health and the environment if exceeding limits, especially for AB glue used in food-contact, medical, and children’s product applications. Under the EPA’s Toxic Substances Control Act (TSCA) regulations, all imported AB glue must report the content of 12 key harmful substances if manufactured or imported since January 1, 2011. The EPA has set legally enforceable limits for these substances: lead content shall not exceed 100 ppm (0.01%), cadmium content shall not exceed 50 ppm (0.005%), formaldehyde content shall not exceed 100 ppm (0.01%), benzene content shall not exceed 5 ppm (0.0005%), and phthalate content (including DEHP, DBP, BBP) shall not exceed 0.1% (1000 ppm) for general industrial-grade AB glue. For food-contact and medical-grade AB glue, the limits are further tightened: lead content ≤10 ppm, cadmium content ≤5 ppm, formaldehyde content ≤50 ppm, benzene content ≤1 ppm, and phthalate content ≤0.01% (100 ppm). Additionally, the EPA has set strict VOC limits for AB glue containing organic solvents: no more than 500 g/L for industrial-grade AB glue and no more than 100 g/L for food-contact and medical-grade AB glue. Enterprises should also verify harmful substance content in raw materials, as the U.S. TPCH (Toxic Packaging Clearinghouse) has issued guidelines requiring confirmation of intentional addition of heavy metals and PFAS in adhesive products, with testing recommended for total heavy metal content to ensure compliance.
The EPA released a proposed revision to harmful substance reporting rules in November 2025, extending the original April 13, 2026, deadline and introducing exemptions for technically unavoidable trace impurities, but enterprises must not rely on these exemptions until the final rule is published. More critically, several U.S. states have implemented stricter restrictions on harmful substances in adhesive products, including AB glue. California has enforced strict restrictions through AB 1817 (effective January 1, 2025) and SB 682 (proposed in March 2025, to be enforced from January 1, 2027), which explicitly limit the content of heavy metals and PFAS in industrial raw materials and adhesive products sold in the state. The specific requirements for AB glue are: total content of lead, cadmium, mercury, and hexavalent chromium shall not exceed 100 ppm starting January 1, 2025, and shall be reduced to no more than 50 ppm starting January 1, 2027; from January 1, 2027, the sale or distribution of AB glue containing intentionally added PFAS will be prohibited, except for products where PFAS use is deemed unavoidable by the California Department of Toxic Substances Control (DTSC). Manufacturers selling AB glue in California must also provide a certificate of conformity confirming compliance with these limits, signed by an authorized official. New Jersey, effective January 12, 2026, via S1221, prohibits the sale of new AB glue with intentionally added heavy metals or PFAS exceeding the state’s limits, exempting used products and unavoidable impurities. In addition to California and New Jersey, Washington State and Minnesota (both effective January 1, 2025) have set stricter limits on formaldehyde and arsenic content in AB glue; Rhode Island (effective January 1, 2025) bans the sale of AB glue containing any mercury or hexavalent chromium. Failure to comply with state chemical restrictions can result in severe state-level fines—up to $2,500 per day in California and $10,000 per day in New Jersey—and permanent market exclusion in the respective states.
Additionally, AB glue used in food-contact materials (e.g., food packaging sealing, food processing equipment bonding) or medical devices (e.g., medical device assembly, disposable medical product bonding) must comply with FDA regulations on migratable substances, ensuring no harmful chemicals leach into food or come into contact with human bodies. Enterprises must conduct strict quality control on raw materials and finished products, and provide third-party test reports to confirm compliance with these chemical limits when importing to the U.S. For AB glue used in children’s product packaging or assembly (e.g., toy bonding), additional compliance with CPSC (Consumer Product Safety Commission) regulations is required, including total lead content ≤100 ppm and phthalate content ≤0.1%. OSHA has also updated its workplace safety standards for AB glue, requiring that imported AB glue must be labeled with clear hazard warnings (e.g., flammable, corrosive) and comply with OSHA’s Hazard Communication Standard (HCS 2012), which mandates detailed information on chemical hazards, first-aid measures, and protective equipment.
Third, safety certification and standards are mandatory prerequisites for market access, with differentiated requirements based on application scenarios. AB glue imported into the U.S. must comply with relevant federal standards and obtain mandatory certifications to ensure their safety, durability, and environmental performance. The core certifications for AB glue vary by application: for general industrial-grade AB glue, compliance with ASTM D1002 (standard for adhesive bond strength) and ISO 9001 (quality management system) certification is mandatory; for food-contact grade AB glue, compliance with FDA 21 CFR Part 175 (food-contact materials regulations) and ISO 22000 (food safety management system) certification are necessary; for medical-grade AB glue used in medical device assembly, compliance with ASTM F1585 (standard for medical device adhesives) and ISO 13485 (medical device quality management system) certification are required; for AB glue used in children’s product assembly, compliance with CPSC 16 CFR Part 1303 (lead content limits) and ASTM F963 (standard for children’s products) certification is mandatory.
Certification processes involve type testing and factory audits by accredited third-party laboratories, ensuring that AB glue meets strict requirements for material composition, harmful substance content, adhesion strength, curing speed, temperature resistance, and environmental friendliness. For example, food-contact grade AB glue must undergo migration testing to confirm no harmful substances leach into food simulants; medical-grade AB glue must undergo biocompatibility testing to ensure no adverse reactions when in contact with medical devices or human skin; children’s product AB glue must undergo lead and phthalate testing to comply with CPSC standards. Testing frequency is mandated: at least once for the first 500 sets of each AB glue specification, and every 3000 sets thereafter. For AB glue designed for high-risk applications (e.g., medical device assembly, food-contact packaging), more frequent testing and stricter quality control are required to avoid potential safety hazards.
Labeling requirements for AB glue are strict and multifaceted, with mandatory markings in English. The country of origin (“Made in China”) must be clearly, permanently marked on the product packaging (and on the product container if possible, using engraving or spraying)—removable stickers may be deemed non-compliant by CBP. The origin label must be sufficiently visible (font size not less than 10pt) and placed in a prominent position on the packaging (e.g., the outer surface of the packaging box, the side of the glue container). Product information, including material composition (e.g., “Epoxy AB Glue,” “Acrylic AB Glue”), curing type (e.g., “Fast-Curing, 5 Minutes”), adhesion strength (e.g., “Adhesion Strength: 25 MPa”), product type (e.g., “Industrial-Grade AB Glue,” “Food-Contact Grade AB Glue”), and application scenario (e.g., “For Electronic Assembly Only,” “For Food Packaging Sealing”), must be accurately labeled on each package. For AB glue used in food-contact or medical fields, labels must also include FDA compliance marks and a statement confirming compliance with relevant safety standards. For children’s product AB glue, labels must indicate compliance with CPSC 16 CFR Part 1303 and ASTM F963 standards. Additionally, AB glue containing flammable or corrosive substances must be labeled with hazard symbols (e.g., flame symbol for flammable, corrosion symbol for corrosive) and safety warnings (e.g., “Keep Away from Open Flames,” “Avoid Skin Contact,” “Use with Ventilation”).
For California-bound shipments, Prop 65 warning labels are required if the AB glue contains lead, cadmium, formaldehyde, benzene, or other regulated chemicals above threshold levels. California’s Prop 65, officially the Safe Drinking Water and Toxic Enforcement Act of 1986, targets various chemicals that may cause cancer or reproductive toxicity, requiring operators to provide clear and reasonable warnings for potential risks in adhesive products, with approximately 700 chemicals currently regulated. All labels must be durable (resistant to wear, moisture, and corrosion) and easily visible to consumers and inspectors. Additionally, safety warnings (e.g., “Avoid Inhalation of Vapors,” “Keep Out of Reach of Children,” “Store in Cool, Dry Place”) are mandatory to avoid improper use and potential safety hazards.
2. Key Precautions for Maritime Shipping of AB Glue to the U.S.
Maritime shipping is the primary logistics method for Chinese AB glue enterprises exporting to the U.S., given the large order quantity (usually thousands or even tens of thousands of sets per order), high unit value, and long-distance transportation requirements. However, it requires strict adherence to packaging standards, documentation requirements, customs procedures, and inspection risk management. Given the 2026 CBP, EPA, and OSHA inspection protocols that prioritize imported industrial raw materials, Chinese-origin shipments, and products containing harmful or hazardous substances—along with the updated harmful substance and safety certification requirements—enterprises must pay extra attention to the following points to avoid cargo detention, damage, or fines. AB glue is characterized by vulnerability to leakage, deterioration, and safety hazards (flammable, corrosive) during long maritime transit; its chemical properties and packaging requirements demand targeted handling measures to protect product quality and compliance.
First, ensure packaging compliance and product protection. AB glue, especially solvent-based AB glue, is flammable and corrosive—leakage during maritime transit can cause safety hazards (e.g., fire, corrosion of other goods) and environmental pollution, which may result in severe fines and cargo detention. It is also prone to deterioration due to temperature fluctuations during maritime transit (cabin temperatures may range from 0°C to 40°C), which can reduce adhesion strength, extend curing time, and even render the product unusable. Additionally, AB glue containers may be damaged by vibration or impact during loading, unloading, and transit, leading to leakage. Therefore, enterprises must prioritize leakage prevention, corrosion resistance, temperature control, and shock resistance in packaging.
AB glue should be sorted by specification (material, curing type, application) and each set (including glue and hardener) should be packaged in corrosion-resistant, leak-proof containers (e.g., HDPE plastic bottles, glass bottles with sealed caps) with a layer of shock-absorbing material (e.g., foam, bubble wrap) around the container to prevent damage and leakage. Each container must be labeled with product specifications, hazard warnings, and compliance marks, and sealed tightly with a tamper-evident seal to avoid leakage. For solvent-based AB glue (flammable), additional fireproof packaging (e.g., fireproof plastic bags, metal boxes) should be used to reduce fire risks. Each batch of AB glue should be placed in thickened, corrosion-resistant cartons with leak-proof liners (e.g., plastic liners) to contain any potential leakage, and the cartons should be marked with “Flammable” or “Corrosive” hazard symbols in accordance with international maritime dangerous goods (IMDG) codes. For food-contact and medical-grade AB glue, separate sterile packaging should be used to avoid cross-contamination, and the packaging should be marked with “Food-Contact Grade AB Glue – Sterile” or “Medical-Grade AB Glue – For Medical Device Use Only” to remind handlers of special requirements. Each carton should contain a fixed quantity of AB glue (e.g., 20 sets per carton, 100 sets per carton) and be labeled with product specifications, material composition, and application scenario to facilitate identification.
The packaged products should be fixed on wooden pallets (compliant with ISPM 15 standards) with high-strength, corrosion-resistant straps to ensure stability during transit and avoid damage caused by vibration or impact. Wooden pallets must be heat-treated (HT) or fumigated (MB), and display visible IPPC marks with country code, treatment enterprise number, and method. A fumigation certificate is mandatory for wooden pallets to avoid quarantine delays at U.S. ports, in line with U.S. wooden packaging inspection requirements. Pallets must be strong enough to withstand stacking pressure during transit—thickened wooden pallets (load-bearing ≥1500 kg) are recommended for AB glue packages—to avoid damage to the products inside due to excessive pressure. Attention must also be paid to weight and volume limits: general-purpose 20-foot containers have a typical cargo weight limit of 17.3 tons and volume limit of 33 cubic meters, while 40-foot high-cube containers are limited to 19.5 tons and 76 cubic meters (including packaging). AB glue has a high density; enterprises should optimize packaging (e.g., reducing redundant packaging, using compact containers) to maximize container utilization, avoiding over-weight or over-volume shipments. Over-weight or over-volume shipments may incur heavy fines or require offloading and redistribution at the port, leading to delivery delays and additional costs (such as demurrage and detention fees).
External packaging (cartons, metal boxes, or pallets) must display clear compliance marks, including ISPM 15 marks for wooden pallets, permanent “Made in China” origin labels, 8-digit HTS code (35061000, 32081000, or other applicable subcodes), relevant certification marks (ASTM, ISO 9001, FDA, CPSC as applicable), hazard symbols, safety compliance indicators, and shipping marks. Shipping marks must include consignee name, destination port (with state and zip code to avoid misdelivery), package number (e.g., PACKAGE NO. 1/50), gross/net weight, and dimensions, with origin labels separated from other details for visibility. For California-bound shipments, Prop 65 warning labels and harmful substance compliance labels (if applicable) must be visible on outer packaging. For food-contact or medical-grade AB glue, FDA compliance marks and certification numbers must be prominently displayed. The final unloading port must be clearly indicated on the packaging and shipping documents to avoid transit confusion. Additionally, packaging materials should prioritize sustainability, in line with U.S. environmental trends—preferably using recyclable or reusable materials, and meeting New York State’s environmental requirements that packaging materials must have a recyclable ratio of ≥50%.
A Container Packing Certificate and photos of the packing process (including leakage prevention measures, shock-absorbing supports, fixing methods, labeling, and packaging material compliance) can serve as supporting evidence in case of disputes with customs or carriers. Additionally, marking “AB Glue – For [Application: Electronics/Medical/Food], Material: [Epoxy/Acrylic], Type: [Fast-Curing/Solvent-Based]” clearly on outer packaging helps CBP quickly identify the product and speed up clearance. Enterprises should also confirm that packaging materials do not contain intentionally added heavy metals or PFAS, and obtain relevant certification from suppliers if necessary, in line with TPCH guidelines and California’s AB 1817 requirements. They should also maintain records of packaging material compliance, including harmful substance test reports, indefinitely in accordance with risk management policies.
Second, ensure documentation accuracy and completeness, as this is the foundation of smooth customs clearance. Enterprises must prepare a complete set of English-language documents, including a commercial invoice, packing list, bill of lading (B/L), sales contract, certificate of origin, relevant safety certifications (ASTM, ISO 9001, FDA, CPSC as applicable), EPA harmful substance test reports and filing confirmation, material composition reports (detailing material and impurity content), material safety data sheets (MSDS) for AB glue (complying with OSHA’s HCS 2012 standards), fumigation certificates (if wooden pallets or cartons are used), IMDG code compliance certificates (for flammable or corrosive AB glue), and compliance statements for special-grade AB glue (e.g., food-contact grade, medical-grade). As required for maritime shipping, all key documents must be complete to avoid clearance delays—document deficiencies may result in cargo detention, with daily late fees calculated at 0.05% of the goods’ value. CBP may also require any AB glue shipment to be declared formally, regardless of the tariff method specified. For food-contact or medical-grade AB glue, additional FDA test reports and compliance statements must be prepared to confirm compliance with safety standards.
The commercial invoice must include a detailed product description (e.g., “Food-Contact Grade Epoxy AB Glue, Fast-Curing, Adhesion Strength 25 MPa, Compliant with FDA 21 CFR Part 175 and ISO 22000, Model FC-AB-25”) with explicit technical specifications, avoiding vague terms to prevent classification disputes. It must also explicitly state the 8-digit HTS code, declared value reflecting the actual transaction price, and a detailed breakdown of tariff components (MFN, Section 301, import value-added tax) to facilitate CBP calculation. For mixed shipments containing different types of AB glue (e.g., general industrial-grade vs. food-contact grade, solvent-based vs. water-based), separate line items with distinct product descriptions, certification documents, and tariff calculations are mandatory, in line with U.S. customs requirements for separate declaration of different HS codes. CBP cross-references prices with market data for AB glue; underdeclaring can result in fines of 20%-100% of the goods’ value and trigger additional scrutiny. Given that AB glue has different price points based on material, curing type, and application, accurate pricing documentation is particularly important.
The packing list must detail each container’s contents, including the quantity (sets/cartons), specifications (material, curing type, adhesion strength, product type), application scenario, gross/net weight, dimensions, and packaging materials of each AB glue variant. It must also specify compliance details, such as harmful substance test results, certification numbers (ASTM, ISO 9001, FDA, CPSC etc.), hazard classification (e.g., flammable, corrosive), and whether the product requires special handling (e.g., temperature control, fireproof measures). All documents must be consistent in product specifications, HTS codes, declared values, and certification details to avoid CBP suspicion. Documents should be submitted to the customs broker at least 7 days before vessel arrival to facilitate pre-clearance, especially for shipments containing flammable, corrosive, food-contact, or medical-grade AB glue.
Additionally, enterprises should keep electronic copies of all documents for at least 5 years for future audits, as the EPA, CBP, OSHA, and FDA may conduct post-clearance inspections within 3 years of import. Enterprises should also maintain records of packaging material compliance, including harmful substance test reports and supplier certifications, in line with U.S. regulatory requirements for supply chain documentation and TPCH guidelines. Strictly complying with customs clearance procedures is also essential: the Importer Security Filing (ISF), or “10+2 filing,” must be submitted to CBP at least 48 hours before vessel departure, as mandated by U.S. federal regulations for maritime shipping. Late or incomplete submissions incur fines up to $5,000 per shipment and cargo detention.
Proactive inspection risk management is also necessary, as CBP, EPA, and OSHA prioritize AB glue shipments for audits to verify tariff classification, harmful substance content, safety certification, labeling accuracy, packaging standards, and product quality. Inspections take 5-12 business days (longer for flammable, corrosive, food-contact, or medical-grade AB glue) and cost $1,000-$3,500 per shipment, with additional lab testing fees if compliance is questioned. To minimize risk, enterprises should maintain detailed supply chain records and optimize shipment schedules, booking cargo space 6-8 weeks in advance during peak seasons to avoid congestion delays. Additionally, for flammable, corrosive, food-contact, or medical-grade AB glue, enterprises should proactively prepare relevant compliance documents (e.g., IMDG certificates, FDA test reports) to speed up inspection and clearance.
In summary, Chinese AB glue cross-border enterprises must fully understand and strictly comply with the latest U.S. policy restrictions—including tariff policies, chemical restrictions, safety certifications, and labeling requirements—and pay extra attention to packaging, documentation, and customs clearance details when using maritime shipping. Proactive compliance management, accurate documentation, strict adherence to shipping standards, and thorough supply chain record-keeping are the keys to avoiding risks, reducing costs, and ensuring long-term, stable market access to the U.S. during the 12-month tariff adjustment window ending January 1, 2027.
