11 Things Every New Importer Gets Wrong About U.S. Customs
I’ve watched importers throw away thousands on easily preventable mistakes. Here are the 11 that show up every week.
Every week I see the same pattern: a new importer ships their first container, gets a hold notice, and suddenly a $3,000 product turns into a $7,000 nightmare. Most of those costs weren’t penalties. They were avoidable paperwork mistakes, bad assumptions, and shortcuts taken under pressure.
This article breaks down the 11 most common mistakes I’ve seen — and what to do instead.
1. Guessing the HTS code
HTS misclassification is the single fastest way to trigger a hold or an unexpected duty bill. If your broker guesses, you’re gambling. The fix: confirm the code against US HTS or CLAM before you book freight.
2. Under-declaring value
Some importers think declaring a lower value reduces duties. CBP can and will use transaction value analysis. When they find a mismatch, you pay the difference plus penalties.
3. Incomplete commercial invoice
A commercial invoice missing fields — buyer/seller addresses, currency, incoterms, unit price, country of origin — is one of the top causes of “missing documentation” holds.
4. Skipping the import bond
Without a bond, CBP won’t release your cargo. Bond cost is tiny relative to shipment value. Treat it as a non-negotiable line item.
5. Wrong entry type
Standard entry is not always the right choice. If your shipment qualifies for Section 321 / de minimis, filing Type 01 wastes time and money. Know your options before arrival.
6. Missing country of origin
Origin must be marked on the product packaging and documented on the invoice. Both. Missing one is enough to delay release.
7. Blindly accepting supplier shipment terms
FOB Shanghai might sound simple, but who owns the cargo at each leg? Who files the entry? Who pays duties? Unclear incoterms create hidden costs.
8. Ignoring AD/CVD flags
Certain HTS codes and countries of origin carry anti-dumping or countervailing duty risks. If you’re importing steel, glass, solar panels, or certain electronics, screen before you buy.
9. Hiring any carrier without checking CBP bond status
Not all truckers can move bonded freight. Verify the carrier bond before booking in-bond movement.
10. Assuming “released” means complete
Release just means CBP let it leave the port. Final liquidation can take up to a year. Errors found later still carry penalties.
11. Keeping bad records
CBP audits happen years after entry. Keep commercial invoices, packing lists, entry summaries, and broker notes for 5 years minimum.
