Customs bond for non-resident importers: single entry or continuous for US hardware shipments?

A customs bond for non-resident importers guarantees to US Customs and Border Protection that duties, taxes, fees and penalties will be paid. A foreign company can use a single transaction bond per entry or a continuous bond for a year of entries, but Executive Order 14411 is pushing foreign importers toward single bonds.

If you sell servers, switches or storage into the United States from abroad, the bond is easy to treat as a box your broker ticks. That worked for years. In 2026 it stopped being safe to ignore. The rules for foreign importers of record are being rewritten, the bond options open to them are narrowing, and the difference between the two bond types can decide whether a high-value shipment clears on the day it lands or waits while someone arranges security.

This guide explains what a customs bond for non-resident importers actually covers, how CBP sets the amount for each type, what Executive Order 14411 changes and what is still pending, and how to choose for the kind of hardware shipments a technology company usually makes. It is written for foreign manufacturers, distributors and integrators who do not have a US company and need to deliver anyway.

What is a customs bond, and why does a foreign importer need one?

A customs bond is a three-party contract between the importer, a surety company and CBP. If the importer fails to pay duties or comply with entry rules, the surety pays CBP and then recovers the money from the importer. Almost every formal entry needs one, and a foreign importer cannot enter goods without it.

The bond exists because CBP releases goods before it finishes reviewing the entry. Duties are paid later, classifications can be questioned months afterwards, and the importer may be asked to redeliver goods that did not meet a requirement. The bond is what lets CBP release cargo quickly while keeping a claim on someone with money in the United States. The standard conditions for importers are set out in the customs regulations at 19 CFR 113.62, the basic importation and entry bond.

For a foreign company, the bond is tied to its status as a nonresident. Under 19 CFR 141.18, a nonresident corporation may make entry only if it has a resident agent authorized to accept service of process and files a bond on CBP Form 301 with a resident corporate surety. In plain terms, CBP wants a person in the country it can serve legal papers on and a US surety that will answer for the money. If you want the broader picture of how the role works, our guide on what an Importer of Record is and when you need one is a good starting point.

Most technology shipments need a bond because they need a formal entry. Under 19 CFR 143.21, informal entry is generally limited to shipments valued at 2,500 US dollars or less. A single GPU server is often worth more than ten times that, so for this kind of cargo the question is never whether you need a bond, only which one.

Single transaction bond or continuous bond: what is the difference?

A single transaction bond, also called a single entry bond, covers one entry at one port. A continuous bond covers all entries the importer makes at any port for a year and renews automatically. The single bond is simpler to obtain for one shipment; the continuous bond is usually much cheaper for anyone who imports more than a few times a year.

The amounts are set very differently, and that is where the cost gap comes from. CBP's current guidance, A Guide for the Public: How CBP Sets Bond Amounts, published in February 2024 as CBP Publication No. 3569-0224, says a single transaction bond will generally be no less than the total entered value plus all duties, taxes and fees that apply. For restricted merchandise subject to the requirements of other agencies, the bond rises to three times the value. A continuous importer bond, by contrast, is set at the greater of 50,000 US dollars or 10 percent of the duties, taxes and fees paid over the previous 12 months, rounded in steps of 10,000 dollars up to 100,000 and in steps of 100,000 above that.

Notice what drives each number. A single bond tracks the value of the goods, so a 400,000 dollar shipment of servers needs a bond of at least 400,000 dollars plus duties and fees. A continuous bond tracks the duties you paid, not the value you imported, so a company bringing in several million dollars of mostly duty-free hardware a year can often stay at the 50,000 dollar minimum. The surety premium follows the bond amount, which is why high-value, low-duty hardware is exactly the cargo where single bonds hurt most.

There is also a timing difference. A single bond has to be in place and accepted for each entry before release, so every shipment depends on the surety turning the bond around in time. A continuous bond is approved once, and after that the broker simply references it. For a project with a fixed installation date, that difference is worth more than the premium.

What does Executive Order 14411 change for foreign importers?

Executive Order 14411, Strengthening Customs Enforcement, signed on June 3, 2026, directs CBP to stop foreign importers of record from relying on continuous bonds for formal entries, unless CBP accepts that the revenue is fully protected. It also bars them from informal entries and ties them to CTPAT. Most of these changes depend on rules that were still pending in late October 2026.

The order was published in the Federal Register on June 10, 2026. For formal entries, it says a foreign importer of record may not rely on a continuous bond to meet the bond requirements, except as permitted by CBP when the importer has shown that the revenue would be fully protected. The same section requires foreign importers of record to be validated in the Customs Trade Partnership Against Terrorism, if CBP finds them eligible, or to file through a CTPAT-validated licensed customs broker. Separately, it directs CBP to prohibit foreign importers of record from filing informal entries at all, which removes the low-value route for spare parts and samples. Many of its directives carry 180-day deadlines, which run to the end of November 2026.

What has not happened yet matters as much. A related rule on heightened requirements for foreign importers of record went to White House regulatory review in late September 2026, and at the time of writing its text had not been published. Until it is, nobody outside government knows exactly how CBP will judge that the revenue is fully protected, whether existing continuous bonds held by foreign importers will be grandfathered, or how fast the change will apply. Anyone who tells you the final details today is guessing.

One change is already in force. In a Federal Register notice of August 19, 2026, CBP said that from September 18, 2026 it would void importer numbers when the identity data on CBP Form 5106 is inaccurate or incomplete. A bond does not help if the importer number behind it has been voided, so the bond and the importer record have to be right together. Our guide to the Importer of Record in the USA walks through Form 5106 and the other 2026 changes in more detail.

How much will a single entry bond cost on a hardware shipment?

The bond amount for a single entry is driven by the value of the goods, so on servers and network gear it is large even when the duty is low. The premium is a percentage set by the surety, often with a minimum charge, and it is paid every time. For high-value hardware, the bond can become one of the larger clearance costs.

Take a simple case. A foreign manufacturer ships 400,000 dollars of servers to a US customer. Many server and computer lines carry a zero ordinary duty rate in the Harmonized Tariff Schedule of the United States, but the entry still pays the Merchandise Processing Fee, and additional duties may apply depending on the product and its origin. Under CBP's guidance, the single bond must cover at least the 400,000 dollar value plus those duties, taxes and fees. If the same company ships six times a year, it buys six bonds of that size, while a continuous bond for the same activity might sit at the 50,000 dollar minimum.

Additional duties change the arithmetic quickly. If a shipment includes products subject to the Section 232 duties on certain advanced semiconductors, the duty part of the bond grows with them, and so does the surety's appetite for collateral. Our analysis of the Section 232 semiconductor tariff on servers and GPUs explains which products are affected. Sureties price foreign principals cautiously in any case, and many ask a non-resident company for collateral, a letter of credit or a parent guarantee before they will write a large single bond. That paperwork takes time, and it has to be repeated if the shipment profile changes.

There is a cash flow side as well. Collateral tied up for each shipment is money that is not available for production or inventory. For a company shipping a few racks a quarter, that can be manageable. For one delivering a phased data center project, the collateral for overlapping shipments can add up faster than the margins.

Does the bond cover the Importer Security Filing too?

Not automatically. Ocean shipments need an Importer Security Filing before loading at the foreign port, and that filing needs its own bond coverage. A continuous importer bond can cover it when the right activity is included; otherwise a separate ISF bond is needed, with its own minimums.

CBP's bond guidance sets the minimum for a continuous ISF bond at 50,000 US dollars and for a single transaction ISF bond at 10,000 US dollars. The ISF has to be filed by the importer or its agent at least 24 hours before the cargo is loaded abroad, which means the bond coverage has to exist before the goods even leave. For air freight, which is how most high-value servers travel, there is no ISF, but the entry bond still has to be ready before the plane lands.

This is where foreign sellers get caught. A shipment is booked, the vessel cut-off approaches, and only then does someone ask who will file the ISF and under which bond. If the answer is a single ISF bond for a non-resident principal the surety has never seen, a day or two can disappear. Planning the bond with the booking, not after it, avoids that.

Which option makes sense for your hardware shipments?

If you import rarely, a single transaction bond in your own name can work. If you import regularly, a continuous bond is cheaper but is the option Executive Order 14411 restricts for foreign importers. Many foreign sellers will find that using a US-based Importer of Record, with its own continuous bond and compliance history, is the practical middle route.

Think about it in terms of frequency, value and control. A company that ships one high-value order a year can live with the cost and lead time of a single bond, provided it starts early and has a broker who knows the surety. A company that ships every month will feel the restriction on continuous bonds directly, and should plan for the possibility that, once the new rule is published, its foreign entity can only use single bonds unless it convinces CBP the revenue is fully protected. A US subsidiary solves that, but it takes months and only makes sense if the United States is a core, long-term market.

The commercial terms matter too. If you sell Delivered Duty Paid, you are promising the customer a cleared delivery, which means you carry the bond question whether you like it or not. Our guide on DDP for IT hardware explains when that promise works and when it backfires. If the buyer imports, the buyer's bond applies and the problem shifts to them, but you lose control over the delivery date.

How do you set up a bond as a non-resident importer, step by step?

Start with the importer record, then the agent and surety, then the bond itself, and only then book the cargo. Each step depends on the one before it, and doing them in the wrong order is the most common reason a hardware shipment sits in a bonded warehouse while paperwork catches up.

1. Confirm the importer data on CBP Form 5106: the real business address, the company's own email and phone, and the identifiers CBP asks for, since a voided number makes any bond useless.
2. Appoint a resident agent authorized to accept service of process, as 19 CFR 141.18 requires for a nonresident corporation.
3. Choose a licensed customs broker, preferably one validated in CTPAT, and sign the power of attorney so the broker can file on your behalf.
4. Apply to a surety through the broker, with financial statements, expected shipment values and, if asked, collateral or a parent guarantee.
5. Decide the bond type for each lane: single transaction bonds for occasional entries, a continuous bond only if your status allows it, plus ISF coverage for ocean freight.
6. Book the shipment once the bond is approved and recorded, and keep the bond and entry records with the rest of the import file.

What should you do before the new rule is published?

Do not wait for the final text. Clean up your Form 5106 data now, find out whether your broker is CTPAT-validated, ask your surety how it will treat foreign principals once the rule lands, and price your next shipments on single bonds so the budget holds either way.

If you already hold a continuous bond as a foreign importer, keep it current and watch for CBP's implementing notice, because it will say whether and how existing bonds can still be used. If you are planning your first US shipments, assume single bonds for your own entity and compare that cost with the alternative of having a US-based party act as importer. The comparison is often clearer than people expect once the bond, the collateral and the lead time are counted together.

The official reference for how amounts are calculated is CBP's guide on how CBP sets customs bond amounts. It is worth reading alongside your broker's quote, because it shows which numbers are fixed by CBP and which are set by the surety.
