US Customs Bonds: Single Entry vs Continuous — Where's the Break-Even for Your Import Volume

We had a client — sells home goods on Amazon, operates out of City of Industry — who called me early last year with a question about his customs bond. His broker wanted to sell him a continuous bond at $475 a year. Was it worth it? I told him: don't sign anything until we've done the math. Bond money looks small, but buy the wrong one and you're lighting a few hundred dollars on fire every year. Buy the right one and you get your time back too.

He brings in six full containers a year from Ningbo, roughly $80,000 of goods per container. His broker had been buying him a single entry bond for every shipment — $65 a pop — plus another $30 per shipment for the ISF bond. That's 6 × ($65 + $30) = $570 a year just on bonds. I had him switch to a continuous bond: $475 a year, all-in, ISF coverage included (confirm with your broker — not every quote bundles it). He saved close to a hundred bucks. But the money was the small part. The real win was time.

Here's what nobody tells you about single entry bonds: each one has to be bought and issued per shipment, and during peak season your broker is juggling fifty importers at once. Half a day waiting on bond paperwork is normal. The vessel doesn't wait. With a continuous bond, you do the paperwork once a year, it covers every entry at every U.S. port, and shipments just flow. No more holding your breath over a bond.

This same client learned that lesson the hard way the previous peak season. One single entry bond didn't come through until the afternoon of the second day. He nearly missed his pickup window at the port and ate an extra day of demurrage. One day of port storage costs more than whatever he "saved" on that bond. Since then he's religious about it: renew the continuous bond a month early, never gamble a sailing schedule on a broker's turnaround time.

Now the flip side. Another client imports exactly one sample container a year. His broker sold him a continuous bond — $475 — without blinking. A single entry bond would have cost him $65. That's $400 of pure waste. Why do brokers love pushing continuous bonds on low-volume importers? Because it's one transaction a year instead of per-shipment paperwork, and in some shops the commission tracks the premium. Clients, remember this: whenever a broker "recommends" something, ask who it benefits.

Single Entry vs Continuous: What You're Actually Buying

Let's put both products on the table. A single entry bond covers exactly one shipment. The bond amount is typically set against that shipment's entered value plus duties, and the premium runs about $5.50 per $1,000 of bond amount, with a minimum of roughly $55–$75 per entry (get a current quote from your broker — rates move). A continuous bond covers twelve months of entries at every U.S. port. CBP requires a minimum bond amount of $50,000 — roughly 10% of the duties, taxes, and fees you paid over the prior twelve months, rounded up, with $50,000 as the floor. The annual premium usually lands between $400 and $500.

The Break-Even Math on Your Customs Bond

The arithmetic is simple. At $65 per single entry and $475 a year for continuous: 475 ÷ 65 ≈ 7.3. Looks like you need seven shipments to break even. But single entries usually need a separate ISF bond too — another $25–$30 a shipment — pushing the true per-shipment cost toward $90–$95. Now it's 475 ÷ 90 ≈ 5.3. The real break-even sits around five to six entries a year. The industry rule of thumb is even blunter: more than five shipments a year, go continuous; four or fewer, stay single entry; exactly five, look at whether next year's volume is growing or shrinking.

Here's the counterintuitive part: plenty of importers hear "$50,000 bond" and panic, assuming they have to hand over fifty grand. You don't. That's just the coverage limit — the guarantee amount on paper. What you actually pay is a few hundred dollars a year. People scared off by that number keep overpaying per shipment, year after year, essentially paying a tax on their own misunderstanding.

Two more things only the sell side usually knows. First, there's real margin in continuous bond quotes. What the surety charges the broker and what the broker charges you can differ by fifty to a hundred dollars — I've seen a $475 bond quoted at $550 or $600. Get two brokers to quote in writing, bond amount and annual premium spelled out. Paper beats promises. Second, continuous bonds auto-renew. If you don't want it anymore, you must terminate in writing, usually 30 days ahead, or you're billed for another year. I watched a client switch brokers, forget to cancel the old bond, and pay double premiums for six months before anyone noticed. That's the most expensive kind of money — the kind that makes no sound.

Three Questions to Ask Your Broker About Customs Bonds

Question one: "I do about this many entries a year at roughly this value per shipment — run the numbers and show me which is cheaper, single or continuous?" Make the broker show the math. A broker who'll do arithmetic with you is a broker you can trust.

Question two: "Does the annual premium include ISF coverage? All ports? Any per-entry fees on top?" Some brokers unbundle ISF and charge it separately; some add surcharges for regulated commodities. Get it in writing before you sign.

Question three: "When tariffs go up and my bond amount falls short, will you warn me in advance — and do you charge for the increase?" Tariffs have been moving a lot these past couple of years, and CBP sends insufficiency notices when your coverage no longer matches your duty exposure. Fall short and your cargo can get held. A good broker watches your bond sufficiency proactively; a bad one tells you after the container is already stuck. Say it upfront, in an email.

Next time you're reviewing the contract, ask those three questions. A customs bond isn't big money, but it's your line of credit with CBP — buy the wrong one and it costs you cash, buy it late and it costs you the shipment. Five minutes of math beats a week of finger-pointing.
