Customs Bond Explained: Single Entry vs. Continuous, Cost, and How to Get One
What a customs bond is, single entry vs. continuous, cost reference bands, how the bond amount is calculated, and how to apply before your China-to-US shipment clears CBP.
Quick answer: A customs bond is a financial guarantee that you — the importer — will pay all duties, taxes, and fees owed to U.S. Customs and Border Protection (CBP) and follow import regulations. It is a three-party contract between you (the principal), a surety company, and CBP. Most commercial imports valued over $2,500 (and any shipment of regulated goods) require one before cargo will clear. You choose between a single entry bond (covers one shipment) and a continuous bond (covers unlimited entries for a year). Treat every cost figure in this guide as an approximate reference band; the bond amount and premium for your specific shipments require manual confirmation with a surety provider.
TL;DR: A customs bond is not a fee you pay to Customs — it is a guarantee from a surety company that you will meet your obligations. If you ship a few times a year, a single entry bond is usually enough; if you import regularly, a continuous bond almost always costs less per entry and removes per-shipment friction. Size the bond to your expected duties, buy it before your first shipment arrives, and confirm the exact amount and premium with a licensed surety, because figures vary by shipment.
If you are researching a customs bond, the question underneath is usually: "do I actually need one, which kind, and what will it cost me before my goods can leave the port?" This guide answers all three — what a customs bond is and why it exists, how to choose between single entry and continuous, what it costs in reference bands, how the amount is calculated, and how to apply — so your first China-to-US shipment clears without a hold.
Throughout, every dollar figure is an approximate reference band, not a binding price. Bond amounts and premiums depend on your duties, commodity, and shipping frequency, and always require manual confirmation with a surety company or customs broker.
What is a customs bond and why do importers need one?
A customs bond (sometimes called an import bond) is a legal, three-party contract:
- The principal — you, the importer of record, who owes the duties and must follow the rules.
- The surety — a licensed surety company that guarantees payment to CBP if you fail to pay.
- The obligee — U.S. Customs and Border Protection, the party the guarantee protects.
Its purpose is simple: CBP collects duties and enforces regulations on millions of entries, and it cannot chase every importer individually. The bond shifts that risk to a surety. If you do not pay duties, abandon cargo, or violate a regulation, CBP claims against the bond, and the surety then comes to you to recover what it paid. It protects the government — not you.
You generally need a customs bond when:
- Your commercial shipment is valued over $2,500, or
- Your goods are regulated by another agency (FDA, USDA, EPA, and so on), regardless of value, or
- You are importing under specific entry types that require a bond.
A common misunderstanding is that the bond is a fee paid to Customs. It is not. You pay a premium to the surety company for the guarantee; the duties themselves are separate and still owed to CBP. The bond is what lets your cargo move while those obligations remain open.
Single entry bond vs. continuous bond: which one fits your shipping volume
There are two main types of customs bond, and the right choice comes down to how often you import.
Single entry bond (SEB) — covers one shipment at one port. You buy it per entry.
- Best for: occasional importers, first-time shipments, one-off purchases.
- Typical cost reference band: often priced per entry, frequently with a minimum premium.
- Catch: if you import regulated goods, you may also need a separate ISF bond for ocean shipments, which adds per-shipment cost.
Continuous bond (annual bond) — covers unlimited entries at all US ports for 12 months.
- Best for: anyone importing more than a handful of times a year.
- Typical cost reference band: a single annual premium, sized to a percentage of your expected duties.
- Bonus: a continuous bond also covers the ISF filing requirement for ocean freight, so you avoid buying a separate bond each time.
The practical tipping point most importers hit: once you ship three to five times a year, a continuous bond usually works out cheaper than stacking single entry bonds — and it removes the scramble of arranging a bond for every shipment. This is a reference guideline, not a rule; run the numbers for your own frequency.
For route and provider decisions that connect to your import volume, you can browse destination-country route options and compare Chinese logistics companies to align your shipping cadence with the right bond type.
How much does a customs bond cost? (reference bands)
Cost has two parts, and they are easy to confuse:
- The bond amount — the size of the guarantee (for example, the minimum continuous bond is commonly set at $50,000).
- The premium — what you actually pay the surety each year or per entry, usually a small percentage of the bond amount.
As approximate reference bands:
- Single entry bond premium — often priced per entry with a minimum, commonly in the low hundreds of dollars depending on value and commodity.
- Continuous bond premium — commonly in the low-to-mid hundreds of dollars per year for the minimum $50,000 amount, rising with the bond size and your risk profile.
These are not quotes. Your actual premium depends on your duties, commodity risk, credit, and the surety's underwriting, and it requires manual confirmation. Think of these bands as orientation so you can budget, not as a price you will be charged.
How a customs bond amount is calculated
For a continuous bond, CBP bases the amount on your estimated duties, taxes, and fees for the next 12 months — commonly 10% of that figure, rounded up to the nearest $10,000, with a $50,000 minimum.
A worked example, using reference figures:
- You estimate $180,000 in duties and fees over the coming year.
- 10% of that is $18,000.
- Rounded up to the nearest $10,000 → $20,000, but the $50,000 minimum applies → your continuous bond amount is $50,000.
Only when your expected duties climb above roughly $500,000 does the 10% calculation start to push the bond above the $50,000 floor. For a single entry bond, the amount is usually set at the entered value plus duties, and it can be higher for regulated goods. Because the amount hinges on your specific duty picture, always confirm the calculation with a surety or broker rather than assuming the minimum covers you.
A quick case study. A cross-border seller importing consumer electronics from China sized their continuous bond at the $50,000 minimum based on last year's sales. Midway through the year a product line took off, duties for the rolling 12 months jumped well past expectations, and the bond became insufficient for the entries being filed. CBP flagged the shortfall, and the seller had to increase the bond and reconcile the gap — a delay that held up time-sensitive inventory right before a peak sales window. The fix cost far more than the few minutes of reviewing duty projections each quarter would have. The lesson: a bond amount is not set-and-forget; revisit it as your volume changes.
How to get a customs bond: application and timeline
Getting a customs bond is fast compared to most import setup. The usual path:
- Choose where to buy — directly from a licensed surety company, or through a customs broker or freight forwarder who arranges it for you.
- Submit a short application — typically your business details, importer/IRS number, commodity type, and estimated duties.
- Underwriting and approval — for straightforward cases, approval often comes through in one to three business days; some single entry bonds are issued the same day.
- Bond is filed with CBP — once active, your entries can clear against it.
How long it takes depends on underwriting complexity, but most standard importers should budget a few business days, not weeks. Buy the bond before your shipment departs, not after it arrives — cargo sitting at the port without a bond accrues storage and demurrage while you sort paperwork.

Common customs bond mistakes China-to-US importers make
The recurring errors to avoid:
- Waiting until cargo arrives to arrange a bond, then paying storage and demurrage while it sits at the port.
- Undersizing a continuous bond and not reviewing it as duty volume grows, triggering an insufficiency flag.
- Buying single entry bonds repeatedly when annual shipping frequency would make a continuous bond cheaper and simpler.
- Assuming the bond covers the duties — it guarantees payment; you still owe the duties themselves.
- Forgetting the ISF bond for ocean shipments on a single entry basis, which is a separate requirement.
- Confusing the bond with cargo insurance — a customs bond protects CBP; it does not insure your goods against loss or damage.
Frequently asked questions
What is the purpose of a customs bond?
A customs bond guarantees to U.S. Customs and Border Protection that the importer will pay all duties, taxes, and fees and comply with import regulations. It protects the government, not the importer — if you fail to pay, CBP claims against the bond and the surety recovers from you.
Do I need a customs bond for every shipment?
For most commercial imports over $2,500, and for regulated goods of any value, yes — a bond must be in place. Whether that is a fresh single entry bond per shipment or one continuous bond covering all entries depends on which type you hold.
How long does it take to get a customs bond?
For straightforward applications, approval commonly takes one to three business days, and some single entry bonds are issued the same day. Complex or higher-risk underwriting can take longer, so apply before your shipment departs.
How much is a CBP bond payment?
There is no single "CBP bond payment." You pay a premium to a surety company, typically a small percentage of the bond amount — commonly in the low-to-mid hundreds of dollars per year for a minimum continuous bond, as an approximate reference band. The exact premium for your situation requires manual confirmation with the surety.
How do I check my customs bond status?
Your surety company or customs broker can confirm whether your bond is active and sufficient. If you import under a continuous bond, review it periodically against your actual duty volume to make sure it has not become undersized.
