A customs bond is the financial guarantee behind every formal US entry — the surety's promise that duties, taxes and penalties will be paid — and imports stop the moment it fails. Bonds fail two ways: lapse (the continuous bond's annual term not renewed) and INSUFFICIENCY (the bond amount falling below CBP's formula as your duty bill grows — the failure mode that actually catches importers, because it arrives as a CBP letter giving you 15 days while your entries queue).
About Customs Bond Tracker
The sufficiency math is why this tracker pairs the renewal date with a basis field: the minimum continuous bond is $50,000 or 10% of the duties, taxes and fees you paid in the previous 12 months, whichever is greater — and Section 301 era duty bills pushed thousands of importers' formulas past their old bond amounts. Growing imports, new tariff exposure or an antidumping order all mean recomputing sufficiency BEFORE CBP does; a stacked-bond or saturated-bond situation also complicates claims for years. The 60-day amber window fits the surety cycle: renewal or an amount increase needs underwriting (financials for larger bonds), and a terminated-then-replaced bond creates gap risk no importer wants. Track ISF, custodian and India warehouse bonds on the same board — different instruments, same failure pattern: a dated guarantee quietly outgrown by the business it guarantees.

Frequently asked questions
How is the US continuous bond amount determined?+
Greater of $50,000 or 10% of duties, taxes and fees paid in the prior 12 months, rounded per CBP's schedule (to the nearest $10k up to $100k, then $100k increments). A company paying $1.2M annual duties needs a $120k → $200k-rounded bond. Recompute when tariffs, volumes or product mix change — Section 301 famously multiplied many importers' formulas overnight.
What happens when CBP deems a bond insufficient?+
A letter demanding a larger bond, typically with ~15 days before the existing bond is rendered insufficient for new entries — after which shipments need single-transaction bonds (expensive, slow) or simply wait. Sureties also monitor exposure and can terminate. The defensive play is exactly this tracker's basis field: recompute quarterly against your duty run-rate and upgrade before the letter exists.
Continuous bond or single-transaction bonds — which is cheaper?+
The crossover is fast: a continuous bond costs a few hundred dollars a year and covers unlimited entries (plus ISF); single-transaction bonds price per entry against value+duties and add up within a handful of shipments. More than 3–5 entries a year almost always favors continuous. STBs remain right for one-off imports and certain high-risk entries where sureties demand them anyway.
Do other countries have customs bonds like the US?+
The guarantee concept is universal, instruments differ: India uses bonds with bank guarantees for warehousing (the CB bond), EPCG and provisional assessments; the EU runs comprehensive guarantees tied to authorizations (with AEO reductions); the UK similarly post-Brexit. Track each on this board with its own renewal logic — the US annual-renewal-plus-sufficiency pattern is just the most letter-prone version.
