Customs Bonds: Single Entry vs Continuous, and When You Actually Need One

Customs Bonds: Single Entry vs Continuous, and When You Actually Need One

A customs bond is not insurance for your cargo. It is a guarantee to CBP that duty, taxes and fees will be paid, underwritten by a surety, and it is required before an entry can be filed.

The choice between a single transaction bond and a continuous bond looks administrative. It decides how much capital is tied up, how much work each shipment creates, and whether an ISF can be filed at all.

What a bond actually secures

The bond secures the importer's obligations to CBP: duties, taxes, fees, and potential penalties, up to the bond amount.

It is provided by a surety company, and the importer indemnifies the surety. That means the bond is a credit instrument, and the surety's appetite for your business depends on your financials rather than on your cargo.

The importer of record is the party that must hold the bond. Under DDP arrangements, that is the seller's entity, which is why the buyer often has no visibility into the bond behind their own shipment.

The two types

The continuous bond minimum is $50,000, and CBP may require a higher amount based on the duties, taxes and fees paid in the preceding year.

A single transaction bond is priced per shipment and covers only that entry. For an importer shipping twice a year, that can be cheaper. For anyone shipping monthly, it becomes both more expensive and more administrative.

The ISF dimension

ISF filing requires a bond as well, and this is where single transaction bonds surprise people. A shipment can need bond coverage for the ISF and separate coverage for the entry.

With a continuous bond in place, both are covered by the same instrument. Without one, each shipment requires its own arrangement, which is a workflow problem more than a cost problem.

When importers get it wrong

Three situations. A new importer files the first entry on a single transaction bond, then discovers the second shipment needs a new bond before the ISF can be filed.

An importer with a continuous bond lets it lapse at renewal, and the next entry is rejected at filing rather than at arrival. And an importer changes surety without telling the broker, so the bond on file no longer matches the entity.

The fourth is structural: the DDP seller holds the bond, the buyer later wants to clear in their own name, and the transition requires an EIN, a bond and a broker relationship that take longer to arrange than the next shipment takes to arrive.

How to decide

If you import more than a handful of entries a year, a continuous bond is almost always the right structure, on cost and on process.

If you are testing a supplier or importing once, a single transaction bond is proportionate. But check the ISF requirement before booking, not after.

And if you intend to take over your own entry from a DDP provider, arrange the bond before you need it. A lapse in coverage at the wrong moment turns a routine shipment into a storage invoice.

The renewal cycle

A continuous bond runs for a year and is renewed. The renewal is not automatic in the sense that matters: if the surety does not renew, or the importer does not pay the premium, the bond lapses and entries are rejected at filing.

The failure mode is quiet. Nothing stops your shipments; the broker simply cannot file, and the container waits while the bond is reinstated.

Put the renewal date in the same calendar as your other compliance deadlines, and confirm it a month ahead rather than on the day.

What the broker needs from you

A power of attorney, which authorises the broker to act on your behalf. A copy of the bond or the bond number. And the importer of record number, which for a company is an EIN.

None of these are difficult, and all of them are prerequisites. The delay is always sequencing: a new importer discovers the requirement when the first shipment is already booked.

Establishing the three items takes a few days and can be done before the first purchase order. There is no reason to discover them at the port.

When the bond amount needs to increase

A continuous bond is sized against prior-year duty volume. An importer that grows quickly can outgrow the bond without noticing, and the symptom is a bond insufficiency notice rather than a clean rejection.

The trigger is usually a large shipment or a change in duty rates. If the duty on a single entry approaches the bond amount, the surety will want the bond increased before the entry is filed.

Ask the surety annually whether the amount still matches the volume. It is a five-minute question, and the alternative is finding out during a peak-season shipment.

The bond is the least interesting document in the file and the one that stops the entry when it is missing. It is worth ten minutes at the start of a supplier relationship.
