**Short answer:** A customs bond is a contract in which a surety guarantees to CBP that the importer will pay duties, taxes, and fees and meet the entry obligations. Every formal entry needs one, which generally means any commercial shipment over 2,500 dollars. The choice is a single transaction bond for one entry, or a continuous bond that covers all entries at all ports for a year.

## The guarantee CBP holds before it releases your goods

A customs bond is not insurance for the importer. It is a financial guarantee to CBP, and the distinction matters, because if the surety pays a claim, it recovers the money from you. The bond says the importer of record will pay the duties, taxes, and charges imposed when goods are released into commerce, produce required documents, redeliver merchandise when CBP demands it, and file the Importer Security Filing correctly. Those conditions are written in 19 CFR 113.62, and they are the same for every importer, whether the shipment is one pallet or one container.

The trigger is formal entry. Under 19 CFR 142.4, merchandise on a formal entry is not released from Customs custody until a single entry or continuous bond on CBP Form 301 is on file. Formal entry generally applies above the 2,500 dollar informal entry limit, and some goods need formal entry whatever their value, including goods subject to partner government agency requirements, temporary importations, warehouse entries, and in-bond movements. Since the de minimis suspension, low-value shipments need entries too, which is why importers who never needed a bond before are suddenly shopping for one.

## Single transaction or continuous

A single transaction bond covers one entry at one port. Its amount starts at the entered value plus duties, taxes, and fees, and rises to three times the value for restricted merchandise. It suits an occasional shipment, and it is priced per shipment, which means the cost grows with every entry.

A continuous bond covers all entries at all ports for a year and renews annually. CBP sets the amount at 50,000 dollars or 10 percent of the duties, taxes, and fees paid in the previous twelve months, whichever is greater. The breakeven is low: once an importer is filing more than a handful of formal entries a year, the continuous bond costs less in total, and it removes a per-shipment task from the process. It also covers the Importer Security Filing, which a single transaction bond does not. Shipments have been held because the entry bond was arranged while the ISF bond was not, and the ISF carries its own 5,000 dollar per violation exposure.

## The mistakes that cost real money

The first mistake is treating the bond as a formality and letting it lapse. CBP gives fifteen days from notice to remedy an insufficient bond, and a lapsed bond means entries do not release. The second mistake is buying the bond after the goods ship. The bond must be on file before release, and a shipment that arrives without one sits at the port on demurrage while the paperwork catches up. The third is the non-resident trap: a foreign seller shipping DDP must have the bond in place before the first shipment, and a non-resident corporation cannot enter merchandise for consumption unless it appoints a U.S. resident agent and posts a bond.

The rule of thumb is simple. If you import more than a few times a year, or by ocean at all, buy the continuous bond and stop thinking about it. If you import once, buy the single transaction bond and remember the ISF needs its own coverage. Either way, the bond is the cheapest line on the entry and the one that can hold the whole shipment. For the duty side of the same entry, [the IOSS 150 euro threshold](https://bordereasehq.com/blog/2026-11-13-ioss-150-euro-threshold-2026.md) covers the EU small-parcel rule, and [country of origin marking](https://bordereasehq.com/blog/2026-11-13-country-origin-marking-made-in-usa.md) covers what must be printed on the goods.

A bond is not a one-time purchase. It renews every year, and the surety reprices it on your import volume and your compliance record. A clean year with no claims is the cheapest way to lower the premium, which is another reason to get the classification right the first time.

## Frequently asked questions

### When is a customs bond required?

For every formal entry of commercial goods, which generally means shipments over 2,500 dollars, plus certain goods that need formal entry at any value, like goods subject to partner government agency requirements, warehouse entries, and in-bond movements.

### How much does a continuous bond cost?

CBP sets the bond amount at 50,000 dollars or 10 percent of the duties, taxes, and fees paid in the previous twelve months, whichever is greater. The surety sets the premium, which is a small fraction of the bond amount, usually a few hundred dollars a year.

### Does a single transaction bond cover the ISF?

No. A continuous bond covers the Importer Security Filing; a single transaction bond does not, so an ISF bond is needed separately for ocean shipments. Shipments have been held because the entry bond was arranged and the ISF bond was not.

### What happens if my bond is insufficient?

CBP gives fifteen days from notice to remedy it. Until then, entries may not release, and the shipment sits at the port. A lapsed or insufficient bond is one of the cheapest problems to prevent and one of the most expensive to fix late.
