Switching customs brokers without missing a shipment: a step-by-step guide
Switching brokers has a reputation for being painful. Here's what actually happens the week you switch (POA, bond continuity, CBP payment setup) and how to keep cargo moving.
By Joy Xue
The short answer: switching customs brokers takes about a week, involves no filing gap, and starts with one document: a power of attorney for the new broker. Your bond stays yours, shipments in flight finish with your old broker, and new shipments file under the new one. Here is the whole process, step by step.
Most importers stay with a broker they’ve outgrown, or one that keeps surprising them on the invoice, for one reason: switching sounds like a project. It isn’t. Here’s what actually happens, so you can decide with clear eyes.
The reputation vs. the reality
The fear is that switching means downtime: cargo stuck at the port while paperwork catches up. In practice, a switch is mostly a few setup steps that run in parallel with your existing broker still covering anything in flight. Done right, there’s no gap. The whole thing is usually about a week.
The switch week, day by day
| When | What happens | Who does it |
|---|---|---|
| Day 1 | Sign the new power of attorney (e-signature is fine) | A company officer |
| Day 1–2 | New broker verifies your importer identity details against CBP’s records | The broker |
| Day 2–5 | Bond check (or new bond arranged) and direct-to-CBP ACH payment setup | The broker |
| Day 3–7 | First new entries file under the new broker | The broker |
| ~Day 7 | In-flight shipments have cleared with the old broker; revoke the old POA, settle invoices | You |
What actually happens
- Sign a new power of attorney. This is the core step. It gives the new broker authority to file for you. It’s a form, signed by an officer of your company; no notary needed, e-signature is generally fine. Same day. One thing a careful broker will insist on: the POA comes from your company directly, not routed through a forwarder or other middleman, because customs law requires it.
- Confirm your bond. Here’s the part almost everyone gets wrong: a continuous bond belongs to your company, not to your broker. It stays in force when you switch, and nothing needs “transferring.” Your new broker confirms it’s active and sized correctly (CBP wants roughly 10% of your last 12 months of duties, taxes, and fees, with a $50,000 floor). If you don’t have a continuous bond, or yours is about to renew, the new broker arranges one; CBP’s paperwork on a new bond can take a week or so, which is why it starts on day one while everything else proceeds.
- Set up direct-to-CBP payment. If you want to stop paying a duty-advance fee, this is where you establish ACH payment to CBP (and optionally Periodic Monthly Statement for float). Do it during onboarding so it’s live for your first entries. It’s free to set up, and it’s the single biggest line-item saving most switchers find.
- Hand over the basics. Your product list and prior classifications, importer number, and any open items. A good broker will ask for exactly what they need and not much more. Expect them to independently verify your importer identity details (name, address, phone, email, tax ID) rather than just copying them over: since September 2026, CBP voids importer numbers whose data on file is inaccurate, so the verification protects you.
- File the first entries in parallel. New broker takes new shipments; anything already in motion finishes cleanly. No cargo waits on the transition.
What to have ready
- A company officer available to sign the POA.
- Your importer number (for a U.S. company, your EIN doubles as this).
- Recent entry summaries (the 7501s), useful for both continuity and a savings review.
- Your current bond details, if you have a continuous bond.
What can actually go wrong (and how to prevent it)
Three failure modes cover nearly every bad switching story, and all three are preventable:
- The importer identity details on file are stale. If the address or contact information CBP holds for your importer number doesn’t match reality, filings snag, and under CBP’s 2026 accuracy rules a stale record can void the number outright. Prevention: let the new broker verify the record during onboarding, before the first entry, and fix anything off.
- The bond quietly lapsed or went insufficient. If your duties spiked this year (tariffs did that to a lot of importers), a bond sized for last year’s duty bill may be flagged insufficient. Prevention: the day-one bond check. A rider or replacement started early never delays cargo.
- Nobody owns the in-flight entries. If the old relationship ends abruptly, an entry mid-review can sit with no one watching it. Prevention: keep the old POA alive until in-flight work clears, then revoke it in writing. A week of overlap costs nothing.
When you should not switch
Honesty item: a switch isn’t always the answer. If your broker is accurate and responsive and your complaint is purely price, ask them to re-quote first; some will. If you’re mid-audit or mid-protest, finish it where the records live, or coordinate the handoff carefully. And if you import twice a year with no complications, the savings may not be worth even a week of admin. The good reasons to switch are recurring surprises on invoices, unexplained fees (especially a percentage-based duty-advance charge), slow answers when cargo is on the water, and classification work you’ve stopped trusting.
A quiet upside of switching
A switch is a natural moment to get a second set of eyes on your classifications and fees, the things that quietly cost you on every shipment. Many importers discover during the move that they’ve been overpaying duty on a misclassified product, or paying a percentage-based duty-advance fee they never needed to. (Our cost guide itemizes what each fee should run.) The switch pays for itself before the first new entry clears.
