Import Recordkeeping Rules: What to Keep, How Long
U.S. importers must keep the records behind every import classification for five years from the date of entry and produce them whenever CBP demands. Classification is only half the job; proving it after the fact is the other half. Good records turn a customs audit from a crisis into a routine exercise — and missing records can trigger penalties even when the underlying classification was correct.
Why Recordkeeping Is a Legal Duty
Recordkeeping is not just good housekeeping; it is the law. Section 508 of the Tariff Act (19 U.S.C. § 1508) sets the general recordkeeping requirement for import activity, and Section 509 (19 U.S.C. § 1509) gives CBP the power to demand and examine those records. The implementing rules sit in 19 C.F.R. Part 163.
The logic ties directly to reasonable care. The system lets importers classify and declare their own goods up front, with CBP verifying later. That verification only works if the importer can produce the documents that support each declared code. No records, no proof — and CBP treats the inability to substantiate a classification as a compliance failure in its own right.
How Long You Must Keep Records
The general rule is five years. Any record required to be kept under Part 163 must be retained for five years from the date of entry if it relates to an entry, or five years from the date of the activity that required the record to be created.
| Record type | Retention period | Source |
|---|---|---|
| Records relating to an entry | 5 years from date of entry | 19 C.F.R. Part 163 |
| Records not tied to a specific entry | 5 years from the date of the activity | 19 C.F.R. Part 163 |
A practical caution: the five-year clock can run from later events such as a reconciliation, so the safe approach is to treat five years as a floor and key your retention to the latest relevant date, not the earliest.
What Records to Keep: The (a)(1)(A) List
CBP does not leave “what to keep” to guesswork. Section 509(e) directs CBP to publish a list of the records that importers must maintain and produce on demand — the (a)(1)(A) list, found in the Appendix to 19 C.F.R. Part 163. Anything on that list is squarely required.
For import classification, the records that matter most include:
- Entry documents — the entry summary (CBP Form 7501) and supporting paperwork.
- Commercial invoices and purchase orders showing what was bought and from whom.
- Bills of lading and packing lists describing the shipment.
- Product information — specifications, composition data, technical sheets, and anything used to determine the code.
- The classification rationale — your analysis, any binding rulings relied on, and CROSS rulings consulted.
- Certificates of origin and free-trade-agreement documentation where preferential treatment was claimed.
Keeping the classification rationale alongside the transactional documents is what lets you reconstruct, years later, why a given code was chosen — which is exactly what an auditor asks.
What Happens If You Cannot Produce Records
The penalties for recordkeeping failures are separate from any duty owed, and they can be significant. Under 19 U.S.C. § 1509(g), failing to produce records demanded from the (a)(1)(A) list can draw a civil penalty of up to $100,000 per release of merchandise for a willful failure, or up to $10,000 per release for a negligent failure.
Read that again: the penalty attaches to the failure to produce, regardless of whether the goods were classified correctly. An importer can have paid every dollar of duty owed and still face penalties simply for not having the paperwork. That is why retention discipline matters as much as classification accuracy.
Building a Records System That Holds Up
A workable system is simple and consistent. Keep records in a format CBP can read and you can retrieve quickly — electronic recordkeeping is fully acceptable and far easier to search. Organize by entry so every shipment’s documents and classification reasoning live together. Set a retention rule that keeps records at least five years from the latest relevant date, and back them up. Periodic internal reviews catch gaps before an auditor does; for the audit side, see how the reasonable-care process and a documented classification method work together.
Frequently Asked Questions
How long do I have to keep import records? Generally five years — from the date of entry for entry-related records, or from the date of the activity for other records, under 19 C.F.R. Part 163.
What is the (a)(1)(A) list? It is CBP’s published list, in the Appendix to 19 C.F.R. Part 163, of the records importers must maintain and produce on demand under 19 U.S.C. § 1509.
Can I be penalized just for losing records? Yes. Under 19 U.S.C. § 1509(g), failing to produce demanded records can draw penalties up to $100,000 per release for willful failures and up to $10,000 per release for negligent ones — separate from any duties owed.
Are electronic records acceptable? Yes. CBP accepts electronic recordkeeping, provided the records are complete, accurate, and can be produced on demand.
