Customs Bonds Are Not Insurance: Single Entry vs Continuous, and What the Surety Takes Back

Most formal US entries cannot proceed without a customs bond — a surety's guarantee to CBP, not protection for your cargo. How Single Entry and Continuous bonds differ, why import frequency decides the choice, how ISF and FDA-regulated cargo affect coverage, and the expensive truth: after the surety pays customs, it collects every dollar back from you.

One word shows up constantly in US import flow and stays half-understood by Taiwanese exporters: Bond. It is not an option or an add-on — most commercial formal entries simply do not proceed without a customs bond, the same class of hard requirement as a passport at the border. What it is, which type to buy, and who pays whom when things go wrong deserve understanding before the first shipment, not after.

What a bond is: a performance guarantee to customs

A customs bond is a surety’s promise to CBP: if this importer fails to pay duties, taxes and penalties, or fails its filing obligations, the surety pays customs first. The protected party is the US government’s claim — not the importer’s cargo — and that orientation drives every rule that follows. Who must hold the bond? The party named as Importer of Record: the bond and the duty liability ride on the same name.

Single vs Continuous: a ticket per ride, or a yearly pass

  • Single Entry Bond: one bond covers one entry, and ends with it. Fits occasional shipments and market-testing phases
  • Continuous Bond: one bond covers all imports for a year at every US port, renewed annually

The selection logic is arithmetic on frequency: a few scattered entries a year favor Single; as cadence rises, per-entry purchases quickly cost more than one annual bond, and Continuous also removes per-shipment arrangement friction. Where the break-even sits depends on current rate structures — have your broker or forwarder run it once and the answer falls out.

Two riders: ocean ISF filings also require bond coverage — a Continuous Bond usually folds it in, while Single-bond shippers must confirm how that leg is covered; and FDA-regulated cargo — categories that can later face redelivery or destruction orders — carries more claim scenarios, so look twice at amounts and conditions.

The expensive misunderstanding: a bond is not insurance

Treating the bond as insurance is the costliest confusion in this topic. Insurance absorbs your loss; a bond advances your debt to customs and then collects it back from you in full. The sequence: you underpay or get penalized, CBP claims against the surety, the surety pays — and the surety’s recovery demand lands on your desk, every dollar, possibly with costs. A bond transfers nothing except customs’ collection risk, and a claim record on your bond degrades next year’s renewal terms and pricing. Bluntly: the bond gets you into the game; compliance is what keeps you from paying.

Where SKYCARGO fits

When SKYCARGO INC serves as Importer of Record, imports run under our own Continuous Bond — duty declaration and bond liability are ours, and you do not need to arrange a bond of your own to ship to the US. On shipments where you hold the IOR name, we help run the Single-vs-Continuous math before you commit. Bond claims and petitions are case-specific legal procedure — consult compliance counsel. B2B shipments, talk to us. (Personal parcels: Shiptw.)

Bond requirements and rate structures follow current CBP law and individual surety terms. Reference only.
