Customs Bonds for Apparel Importers: Why Yours Just Became Insufficient

This page is for apparel importers who have just had a bond-insufficiency notice, or would rather not get one. It sits under UFLPA compliance for apparel brands, the compliance cluster pillar. The trap is simple: the formula is backward-looking and duty-driven, so your bond can become insufficient without you shipping a single extra garment.

What a customs bond is and who has to have one

A customs bond is a three-party guarantee between the importer (principal), a surety company and CBP (beneficiary), that duties, taxes and fees will be paid and entry requirements met. It is not insurance for you — if the surety pays CBP, the surety comes after you.

Any shipment requiring formal entry needs a bond, and the importer of record must hold it. That now reaches further into apparel: the de minimis exemption was indefinitely suspended for all modes other than the international postal network effective 24 June 2026 and terminates permanently on 1 July 2027. Parcels that once slipped under $800 now need entry, and bond coverage.

Continuous bond vs single transaction bond for apparel importers

How the two bond types compare, as of August 2026.

The break-even is low: twelve entries a year at $150 per STB is $1,800, more than a $250,000 continuous bond costs.

How the continuous bond formula works, and why apparel got caught

The required amount is 10% of duties, taxes and fees paid in the prior 12 months, rounded up to the nearest $10,000, subject to a $50,000 minimum. Three components feed the total:

• Duty — MFN plus any Section 301 layer. Apparel MFN runs roughly 0% to 32%, averaging about 14.5% for Chapter 61 knits and 12% for Chapter 62 wovens. Verify against the current HTSUS.
• MPF — 0.3464% of entered value, min $33.58 and max $651.50 per entry in FY2026, rising to $34.58 and $670.86 from 1 October 2026.
• HMF — 0.125% of cargo value on ocean shipments, no minimum and no maximum. See how MPF and HMF are calculated.

The part that caught apparel: the Section 301 forced-labor tariffs took effect 24 July 2026, adding 10% for India, Bangladesh, Cambodia, Indonesia, Jordan, Malaysia, Pakistan and Sri Lanka and 12.5% for China, Vietnam and roughly 38 other economies, on top of MFN. Sheng Lu's FASH455 tracked the average applied rate on US apparel imports rising from 14.7% in January 2025 to 35.1% in December 2025. Apply a backward-looking 10% formula to a duty bill that roughly doubled and the bond roughly doubles too — with a lag, as higher-duty entries roll into the trailing twelve months.

Worked example: a Bangladesh knit program, volume unchanged

A brand imports $2,400,000 of cotton knit tees a year from Bangladesh, across 24 ocean entries of $100,000. HTS 6109.10.00 carries a 16.5% general rate; Bangladesh sits in the 10% Section 301 tier.

Bond calculation on the same program, before and after the Section 301 forced-labor tariff.

Same number of tees, bond requirement up 40%, and the $50,000 floor no longer hiding the increase.

A larger program moves further. Importing $8,000,000 from Vietnam across 40 entries of $200,000, MPF hits the FY2026 cap of $651.50 per entry, so MPF is $26,060 and HMF $10,000. At 16.5% duty the bond was 10% × ($1,320,000 + $36,060) = $135,606, rounded to $140,000. At 29% — 16.5% MFN plus Vietnam's 12.5% Section 301 rate — it is 10% × ($2,320,000 + $36,060) = $235,606, rounded to $240,000, moving the premium into the $900–1,500 band.

What a CBP bond-insufficiency notice means and what to do

CBP monitors bond sufficiency on a rolling basis and notifies the importer and the surety when the bond no longer covers the formula. Practically:

1. The consequence is operational. If the bond is not increased, new entries can be rejected and cargo held. Demurrage runs $100–500 a day and per-diem detention $100–200 a day, tiered so later days cost two to three times the first.
2. Sureties re-underwrite on increase. Expect financial statements, and days rather than minutes.
3. Recalculate before CBP does. Rerun the formula quarterly on a rolling twelve months, and whenever a duty rate changes.
4. Size with headroom. The next $10,000 tier costs little in premium and buys months of margin.

Single transaction bond sizing, with a worked example

An STB covers the entered value plus all duties, taxes and fees on that shipment. Worked on a $40,000 Bangladesh knit shipment at 26.5% all-in duty:

The STB for one $40,000 shipment already exceeds the $50,000 continuous bond floor that covers a whole year of entries. That is the case for a continuous bond in one line.

Detention bonds at three times merchandise value

Separately, CBP may demand a single transaction bond at three times the value of detained merchandise under the basic importation and entry bond conditions at 19 C.F.R. § 113.62. On that $40,000 shipment that is a $120,000 bond, arranged under time pressure while storage and demurrage accrue. Forced-labor detentions are where apparel importers meet this provision; see what happens when CBP detains your shipment.

Executive Order 14411 and bonding for foreign importers

Executive Order 14411, Strengthening Customs Enforcement, signed 3 June 2026, directs DHS and CBP to impose higher eligibility and bonding requirements on importers generally, and specifically to limit continuous bonds for foreign importers, prohibit their informal entries and require CTPAT validation. All importers of record must also disclose ownership, beneficial ownership and domestic assets. Importer eligibility regulations fall around 30 November 2026.

If your structure relies on a foreign entity as importer of record, the bond is where it binds first. Read whether your brand should be the importer of record, and US import duty on clothing in 2026 for the rate layers feeding the formula.
