As a Chinese enterprise engaged in the cross-border business of ABS sheets, 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. ABS sheets are versatile thermoplastic materials widely used in industrial manufacturing, automotive parts, electronic enclosures, construction decorations, and consumer goods, thanks to their excellent impact resistance, toughness, and processability. Due to their extensive application in various fields and direct relevance to product safety and environmental protection, ABS sheets imported from China are 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), Consumer Product Safety Commission (CPSC), Customs and Border Protection (CBP), and Department of Commerce, has intensified regulatory enforcement on imported Chinese ABS sheets, 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 ABS sheet 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 ABS Sheets
The U.S. imposes strict federal and state-level policy restrictions on imported Chinese ABS sheets, with significant updates in 2025-2026 that directly affect cross-border operational costs and market access. ABS sheets have diverse specifications—varying in thickness, width, length, impact resistance grade, flame retardancy, and application scenarios (industrial-grade, automotive-grade, food-contact 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 ABS sheets mainly focus on tariff policies, chemical restrictions (especially PFAS), 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 ABS sheets are primarily classified under HTS 39201000 (for ABS sheets, plates, and strips, not reinforced, modified, or laminated) and HTS 39202000 (for reinforced, modified, or laminated ABS sheets), the core 8-digit codes for ABS sheet exports. The Most-Favored-Nation (MFN) duty rate for ABS sheets ranges from 6.5% to 11.3% depending on the product type, thickness, and application scenario, and critically, they remain subject to the 10% additional Section 301 tariff, resulting in a total combined tariff rate of 16.5% to 21.3%. Importantly, ABS sheets are 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 ABS sheets 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 ABS sheet shipments: due to their material costs (especially high-performance flame-retardant and automotive-grade ABS sheets) and large volume, even small batches (usually 30-50 industrial-grade ABS sheets or 10-20 high-precision automotive-grade ABS sheets) 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 ABS sheet 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 ABS sheets 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 ABS sheets 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 ABS sheets in 2026, requiring detailed product descriptions specifying material composition (e.g., pure ABS, ABS/PC blend), physical parameters (thickness, width, length, impact strength), product type (industrial-grade, automotive-grade, flame-retardant grade), and application scenario (automotive parts, electronic enclosures, construction decorations) to support proper HTS coding. CBP has also emphasized that vague product descriptions such as “ABS Sheets” or “Plastic Sheets” 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 plastic products, including ABS sheets, with no indication of near-term reductions. Furthermore, imported ABS sheets are 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 ABS sheet enterprises a 12-month adjustment window, but compliance with current policies remains the top priority.
Second, chemical restrictions, especially on Per- and Polyfluoroalkyl Substances (PFAS), have become increasingly strict at both federal and state levels, directly affecting ABS sheet production and export. ABS sheets, especially those used for industrial equipment enclosures, outdoor decorations, and food-contact packaging, may contain PFAS in their raw materials, additives, or surface treatments to enhance corrosion resistance, water resistance, and flame retardancy. Under the EPA’s Toxic Substances Control Act (TSCA) regulations, all imported ABS sheets must report PFAS content if manufactured or imported since January 1, 2011. The EPA has set legally enforceable Maximum Contaminant Levels (MCLs) for six PFAS chemicals in products involving water contact or food contact, including PFOA, PFOS, PFHxS, PFNA, PFBS, and HFPO-DA, with limits as low as 4.0 ppt for PFOS. For ABS sheets used in food-contact applications or drinking water-related equipment, even trace amounts of PFAS (≥100 ppm, measured as total organic fluorine) require EPA reporting and compliance with these MCLs. Enterprises should also verify PFAS content in packaging materials, as the U.S. TPCH (Toxic Packaging Clearinghouse) has issued guidelines requiring confirmation of intentional PFAS addition in packaging, with testing recommended for total fluorine content to ensure compliance. Specifically, if the total fluorine content in packaging materials is below 100 ppm and meets quality control standards, the product may be deemed free of intentionally added PFAS; if it is 100 ppm or higher, further investigation is required to confirm whether PFAS were intentionally added.
The EPA released a proposed revision to PFAS 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 PFAS in plastic products, including ABS sheets. California has enforced strict restrictions through AB 1817 (effective January 1, 2025), which explicitly prohibits the manufacture, distribution, and sale of plastic products containing PFAS—ABS sheets are clearly included in the scope. The specific requirements are: no intentional addition of PFAS to ABS sheets or their raw materials; the total organic fluorine content in ABS sheets shall not exceed 100 ppm starting January 1, 2025, and shall be reduced to no more than 50 ppm starting January 1, 2027. Manufacturers selling ABS sheets in California must also provide a certificate of conformity confirming the absence of regulated PFAS, signed by an authorized official. New Jersey, effective January 12, 2026, via S1221, prohibits the sale of new ABS sheets with intentionally added PFAS, exempting used products and unavoidable impurities. In addition to California and New Jersey, Washington State and Minnesota (both effective January 1, 2025) prohibit the sale of ABS sheets with intentionally added PFAS; Rhode Island (effective January 1, 2025) bans the sale of ABS sheets containing any PFAS. 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.
Third, safety certification and standards are mandatory prerequisites for market access, with differentiated requirements based on application scenarios. ABS sheets 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 ABS sheets vary by application: for general industrial and construction-grade ABS sheets, compliance with ASTM D2240 (hardness standard for plastic materials) and ASTM D638 (tensile property standard for plastics) is mandatory, along with ISO 9001 (quality management system) certification; for automotive-grade ABS sheets used in vehicle interiors and exteriors, compliance with ASTM D4812 (impact resistance standard for automotive plastics) and ISO 14001 (environmental management system) certification are necessary, in addition to compliance with FMVSS (Federal Motor Vehicle Safety Standards); for ABS sheets used in food-contact applications (e.g., food packaging, kitchen utensils), compliance with FDA 21 CFR Part 177.1520 (plastic materials for food contact) is mandatory to ensure no harmful substances leach into food; for flame-retardant ABS sheets used in electronic and electrical products, compliance with UL 94 (flame retardancy standard for plastics) is required, with a minimum flame-retardant grade of V-0 for most electronic applications.
Certification processes involve type testing and factory audits by accredited third-party laboratories, ensuring that ABS sheets meet strict requirements for material purity, impact resistance, tensile strength, flame retardancy, high and low temperature resistance, and service life. For example, automotive-grade ABS sheets must undergo impact testing at -40°C to 80°C to confirm adaptability to extreme temperature environments; food-contact ABS sheets must undergo migration testing to ensure no harmful substances (such as heavy metals, plasticizers) leach into food simulators; flame-retardant ABS sheets must pass UL 94 flame retardancy testing to prevent fire hazards. Testing frequency is mandated: at least once for the first 200 units of each ABS sheet specification, and every 1500 units thereafter. For ABS sheets designed for high-risk applications (e.g., aerospace parts, medical equipment enclosures), more frequent testing and stricter quality control are required to avoid potential safety hazards.
Labeling requirements for ABS sheets are strict and multifaceted, with mandatory markings in English. The country of origin (“Made in China”) must be clearly, permanently marked on the product itself (not just the packaging) using printing, engraving, or tamper-proof labels—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 product or its packaging (e.g., the outer surface of the packaging box, the surface of the ABS sheet). Material composition (e.g., “ABS, 100% PFAS-Free,” “ABS/PC Blend”), physical parameters (e.g., “Thickness: 2mm, Width: 1220mm, Length: 2440mm, Impact Strength: 15 kJ/m²”), product type (e.g., “Industrial-Grade ABS Sheet, Flame-Retardant Grade V-0”), and application scenario (e.g., “For Electronic Enclosures Only,” “Food-Contact Safe”) must be accurately labeled on each product or its packaging. For ABS sheets used in food-contact applications, labels must also include FDA compliance marks and a statement confirming compliance with food contact safety standards. Additionally, packaging materials must comply with TPCH guidelines, with labels confirming that no intentionally added PFAS are present if applicable.
For automotive-grade ABS sheets, labels must clearly display the ASTM D4812 standard number and FMVSS compliance marks. For flame-retardant ABS sheets, labels must indicate the UL 94 flame-retardant grade and certification number. For California-bound shipments, Prop 65 warning labels are required if the ABS sheets contain lead, cadmium, formaldehyde, 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 consumer 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., “Do Not Use in High-Temperature Environments Exceeding 80°C,” “Not for Food Contact Without FDA Certification”) are mandatory to avoid improper use and potential safety hazards.
2. Key Precautions for Maritime Shipping of ABS Sheets to the U.S.
Maritime shipping is the primary logistics method for Chinese ABS sheet enterprises exporting to the U.S., given the large order quantity, large volume, heavy weight, 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, CPSC, EPA inspection protocols that prioritize imported plastic products, Chinese-origin shipments, and products for industrial/automotive use—along with the updated PFAS and safety certification requirements—enterprises must pay extra attention to the following points to avoid cargo detention, damage, or fines. ABS sheets are characterized by vulnerability to collision deformation, surface scratches, warpage, and moisture absorption during long maritime transit; their structural integrity and performance require targeted packaging and handling measures to protect product quality and compliance.
First, ensure packaging compliance and product protection. ABS sheets, especially thin-gauge sheets (thickness ≤1mm) and high-precision sheets, are prone to warpage, surface scratches, and edge damage if not properly packaged. They are sensitive to moisture (ABS sheets may absorb moisture in high-humidity environments, leading to surface blistering and reduced impact resistance), salt spray (maritime environment salt spray can cause surface corrosion and discoloration), and impact (which may cause edge chipping and surface scratches). Maritime humidity is high, and cabin temperatures may fluctuate significantly (ranging from 0°C to 40°C), increasing the risk of product damage or performance degradation. Therefore, enterprises must prioritize moisture resistance, anti-scratch, anti-warpage, and anti-collision measures in packaging.
ABS sheets should be sorted by specification (thickness, width, length, product type) and packed individually with PE film or protective film to prevent surface scratches and moisture absorption, then placed in thickened cardboard boxes or plastic containers with foam inserts or corrugated paper supports around the edges to avoid collision and warpage during transit. For large-size ABS sheets (width ≥1500mm or length ≥3000mm) that cannot be packed in boxes, they should be wrapped with waterproof and moisture-proof cloth, and fixed with wooden brackets to maintain flatness and structural stability. Each package should contain a fixed quantity of ABS sheets (e.g., 10 pieces of thin-gauge ABS sheets or 5 pieces of large-size ABS sheets per package) and be labeled with product specifications, material composition, and application scenario to facilitate identification. For high-precision ABS sheets with strict surface requirements, additional protective layers (such as kraft paper) should be added to avoid surface scratches. For flame-retardant or food-contact ABS sheets, separate packaging should be used to avoid cross-contamination, and the packaging should be marked with “Flame-Retardant Product” or “Food-Contact Safe” to remind handlers of special requirements.
The packaged products should be fixed on wooden pallets (compliant with ISPM 15 standards) with PFAS-free straps to ensure stability during transit. 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 ≥1200 kg) are recommended for large-size and heavy ABS sheets—to avoid deformation or damage to the products inside. 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). ABS sheets are relatively heavy and bulky; enterprises should optimize packaging (e.g., using compact stacking, reducing redundant packaging) to maximize container utilization, avoiding overweight or over-volume shipments. Overweight 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 (cardboard boxes, plastic containers, or pallets) must display clear compliance marks, including ISPM 15 marks for wooden pallets, permanent “Made in China” origin labels, 8-digit HTS code (39201000 or 39202000 as applicable), relevant certification marks (ASTM, ISO 9001, FDA, UL 94 as applicable), 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 PFAS compliance labels (if applicable) must be visible on outer packaging, including compliance with SB 682 requirements for future PFAS restrictions. For food-contact ABS sheets, FDA compliance marks must be prominently displayed. For automotive-grade ABS sheets, FMVSS compliance marks must also be 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 moisture-proof measures, anti-scratch wrapping, fixing methods, labeling, and packaging material compliance) can serve as supporting evidence in case of disputes with customs or carriers. Additionally, marking “ABS Sheets – For [Application: Industrial/Electronic/Automotive], Material: [ABS/ABS-PC Blend], Specifications: [Thickness/Width/Length/Flame-Retardant Grade]” 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 PFAS, and obtain relevant certification from suppliers if necessary, in line with TPCH guidelines and California’s SB 682 proposals. They should also maintain records of packaging material compliance, including PFAS 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, UL 94 as applicable), CPSC safety test reports (in line with applicable standards), TSCA Compliance Statement, PFAS test reports and EPA filing confirmation, material composition reports, material safety data sheets (MSDS) for ABS sheet raw materials and additives, fumigation certificates (if wooden pallets are used), and compliance statements for special-grade ABS sheets (e.g., food-contact, automotive-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 ABS sheet shipment to be declared formally, regardless of the tariff method specified. For food-contact ABS sheets, additional FDA test reports and compliance statements must be prepared. For automotive-grade ABS sheets, FMVSS compliance test reports must be included to confirm compliance with safety standards.
The commercial invoice must include a detailed product description (e.g., “Industrial-Grade ABS Sheets, 100% PFAS-Free, Thickness 3mm, Width 1220mm, Length 2440mm, Flame-Retardant Grade V-0, Compliant with ASTM D2240 and UL 94, Model ABS-FR-3”) 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 ABS sheets (e.g., industrial-grade vs. automotive-grade, flame-retardant vs. non-flame-retardant, different thicknesses or material compositions), 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. For food-contact ABS sheets, the invoice must also indicate compliance with FDA 21 CFR Part 177.1520 and include relevant certification numbers. CBP cross-references prices with market data for ABS sheets; underdeclaring can result in fines of 20%-100% of the goods’ value and trigger additional scrutiny. Given that ABS sheets have different price points based on material composition, thickness, and application, accurate pricing documentation is particularly important.
The packing list must detail each container’s contents, including the quantity (units), specifications (material composition, thickness, width, length, product type, flame-retardant grade), application scenario, gross/net weight, dimensions, and packaging materials of each ABS sheet variant. It must also specify compliance details, such as PFAS test results, certification numbers (ASTM, ISO 9001, FDA, UL 94 etc.), and whether the product requires special handling (e.g., moisture-proof, anti-scratch packaging). For food-contact ABS sheets, the packing list must also include FDA test results. For automotive-grade ABS sheets, FMVSS compliance test reports must be included. 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 large-size ABS sheets, food-contact ABS sheets, or mixed variants.
Additionally, enterprises should keep electronic copies of all documents for at least 5 years for future audits, as the CPSC, EPA, and CBP may conduct post-clearance inspections within 3 years of import. Enterprises should also maintain records of packaging material compliance, including PFAS test reports and supplier certifications, in line with U.S. regulatory requirements for supply chain documentation and TPCH guidelines. For ABS sheets subject to California’s SB 682, enterprises should also maintain records of PFAS content to prepare for future regulatory enforcement. 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, CPSC, and EPA prioritize ABS sheet shipments for audits to verify tariff classification, PFAS content, safety certification, labeling accuracy, packaging standards, and product quality. Inspections take 5-12 business days (longer for large-size ABS sheets or food-contact ABS sheets) 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 food-contact or automotive-grade ABS sheets, enterprises should proactively prepare relevant compliance documents to speed up inspection and clearance.
In summary, Chinese ABS sheet cross-border enterprises must fully understand and strictly comply with the latest U.S. policy restrictions—including tariff policies, PFAS 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.
