Customs recordkeeping under 19 CFR 163: the (a)(1)(A) list checked against what you already hold

Which customs records does 19 CFR 163 make you keep?

19 CFR part 163 implements 19 U.S.C. 1508 and 1509, and it uses two categories that carry very different consequences.

Records in the broad sense are defined in 163.1(a): any information made or normally kept in the ordinary course of business that pertains to an importation, declaration or entry, a bonded movement, a drawback claim, the payment of duties, fees and taxes, or another activity CBP's laws require. The definition names statements, declarations, documents, electronic data, books, correspondence, accounts, financial accounting data, technical data and the computer programs needed to retrieve information in usable form. Purchase orders, contracts, payment records, cost build-ups and classification memos all fall here.

Entry records, the "(a)(1)(A) list", are the narrower set required by law or regulation for the entry of merchandise, whether or not CBP asked for them at the time of entry (163.1(e)). The name comes from 19 U.S.C. 1509(a)(1)(A), which required CBP to compile and publish the list. It sits in the Appendix to part 163. CBP's recordkeeping publication explains why it exists: the Customs Modernization Act let CBP stop requiring many documents at the time of entry, and in exchange the importer must keep them and produce them on demand.

The difference is in the penalty. Only entry records on the (a)(1)(A) list carry the administrative penalty in 19 CFR 163.6(b). CBP can still examine the rest and summon them under 163.7, and the Appendix warns that failing to comply can end in penalties set by a court and the loss of import privileges. 163.10 spells out the second part: if a court orders you to obey a summons and holds you in contempt for not doing so, CBP can bar your imports and hold your goods until the contempt ends.

Who has to keep them?

19 CFR 163.2(a), which follows 19 U.S.C. 1508(a), casts the net by activity rather than by title. If your company is the importer of record, the owner or the consignee, files entries or drawback claims, or moves or stores goods in bond, it keeps records. So does anyone acting as its agent, anyone whose work requires a declaration or entry to be filed, and anyone who knowingly causes one of those activities.

That last group can reach a US company that never filed an entry. Under 163.2(b), a domestic buyer "knowingly causes" an importation when it sets the terms of the import, or when it hands the overseas maker technical data, molds, equipment, components or other help knowing they will go into the imported goods. A buyer that only picks finished goods off a dealer's shelf keeps nothing; one whose drawings the foreign plant built to does.

The broker is a separate recordkeeper, not a substitute. It keeps its own records under part 111 (163.2(d)), and when it is not the importer of record CBP treats it as a third-party recordkeeper (163.1(k)) and reaches its files through the third-party summons in 163.8. A demand for entry records addressed to you is still yours to answer within the period, so a broker's copy helps only if you can get it back in time.

How long does each entry's clock run?

19 CFR 163.4(a) sets the general rule: a record that relates to an entry is kept for five years from the date of entry; any other record for five years from the date of the activity that required it. 19 U.S.C. 1508(c)(1) caps what CBP can require at five years from entry, filing of a reconciliation, or exportation. The clock is per entry, not per year or per supplier, which is why it is best computed from the entry export rather than from a filing cabinet.

Which clock a record runs on depends on the event it supports, so the useful way to read 163.4 is from the event:

Because the drawback trigger is worded two ways, keep claim records until the later of the two anniversaries.

A worked example from an entry export, on November 7, 2026:

Two cautions about acting on the "past the period" rows. The five-year limitation period for a Section 1592 penalty runs from the violation, or from discovery for fraud (19 U.S.C. 1621), and an entry under protest, penalty review or litigation needs its records until the matter ends. And a document can relate to more than one entry. A ruling copy or a classification note filed with entry A also supports every later entry of the same part, so file it by product rather than in the oldest entry's folder, where a purge would take it.

What is on the (a)(1)(A) list, and where does each item already sit?

The Appendix to part 163 lists the records in four parts: a general list for most entries, the release data under 19 CFR 141.61, the entry summary data, and documents for special categories of goods. Items marked with an asterisk are, in the Appendix's words, usually on the form and filed with and retained by Customs. That marker matters, because 19 U.S.C. 1509(g)(3)(C) and 19 CFR 163.6(b)(3)(iii) say no penalty may be assessed where the record demanded was presented to and retained by CBP at the time of entry or in response to an earlier demand. The data your broker transmitted and CBP kept is a smaller risk; the documents behind it are where gaps open.

Read as a checklist against what most importers already hold:

Run the checklist from the export, not the folder. Filter the entry export to lines with a special program indicator and confirm a certification exists for each supplier and period. Match the export's entry list to the invoice file and the transport documents. The entries without a match are your recordkeeping gaps, found before anyone asks. Matching broker exports, invoices and ERP data line by line is the subject of reconciling broker entry exports, invoices and ERP data.

The records that are not on the list deserve the same attention for a different reason. Valuation and classification are argued from purchase orders, contracts, payment proof, cost data and product specifications. CBP's reasonable care guidance asks whether you have a complete set of documents ready for review, including purchase orders, invoices, sales agreements, shipping documents and proof of payment.

What happens if you cannot produce a record CBP demands?

A demand for entry records can be written, oral or electronic; an oral demand must be followed in writing or electronically (19 CFR 163.6(a)). The records are due within 30 calendar days of receipt, or sooner where CBP needs them to decide admissibility or release. If you cannot meet the date, ask in writing or electronically before it passes, with the reason. CBP's recordkeeping publication says no sanction is imposed if the extension is approved and the records arrive within it.

If a demanded entry record is not produced, 19 U.S.C. 1509(g)(2) and 19 CFR 163.6(b) allow, for each release of merchandise:

• for a negligent failure to maintain, store or retrieve it, a penalty of up to $10,000 or 40 percent of the appraised value, whichever is less;
• for a willful failure, up to $100,000 or 75 percent of the appraised value, whichever is less;
• and, if the record relates to eligibility for a special rate in column 1 of the HTSUS, liquidation of an unliquidated entry at the column 1 general rate, or reliquidation at that rate of an entry liquidated within the 2 years before the demand, notwithstanding the usual time limits in 19 U.S.C. 1514 and 1520.

A worked example. CBP demands the USMCA certifications for six releases, and the importer cannot produce them because they were never collected from the supplier, a negligent failure:

Those are ceilings. Under 163.6(b)(5) the penalty may be remitted or mitigated under 19 U.S.C. 1618, and CBP's publication says recordkeeping penalties take account of the degree of compliance against the total number of importations, the nature of the records and the recordkeeper's cooperation. The caps are not adjusted for inflation: the 2015 amendments to the Federal Civil Penalties Inflation Adjustment Act exclude penalties under the Tariff Act of 1930 (28 U.S.C. 2461 note, section 4(a)).

The duty consequence often costs more than the penalty. Every unliquidated entry among the six loses the USMCA rate, and so does every entry liquidated within the 2 years before the demand. An entry liquidated earlier than that is outside 1509(g)(2)(C), though a missing certification on it may still raise a Section 1592 question.

Four showings defeat the penalty under 163.6(b)(3), and each needs its own evidence:

The recordkeeping penalty stacks on top of other penalties, with two exceptions in 163.6(b)(4): it does not add to a Section 1592 penalty for a material omission of the same information, or to disciplinary action against a broker under 19 U.S.C. 1641.

A record gap found next to a duty underpayment is a different problem. A missing certification on a line that claimed a preference means the preference may not have been supported when it was claimed; that is a duty question first, and prior disclosure after you find an underpayment covers the route.

When does going paperless need CBP's notice?

Only when you change a record's format. 19 CFR 163.5(a) lets you keep originals on paper or electronically, and 163.1(g) counts electronic data that feeds other records, and readable files such as spreadsheets, as originals. A PDF invoice from the supplier, an EDI message or a purchase order raised in the ERP needs nothing further.

Turning one format into another, such as scanning paper invoices and shredding them or moving archived records into a new system, is an "alternative storage method" under 163.5(b). Its conditions fall into three moments:

• Before you start. Send Regulatory Audit in Charlotte written notice at least 30 calendar days ahead, saying which method you will use and that it meets the 163.5(b)(2) standards. Have written procedures that keep the information intact, readable and secure, with a set way to retrieve it, and an index that lets someone find a given record.
• While it runs. Keep entry records in their first format for 120 calendar days after the later of the release or conditional release period (packing lists excepted; a broker that is not the importer of record and keeps separate electronic records is exempt). Test the system internally once a year. Be able to print, at your own cost, any record CBP asks for. Hold a working copy and a backup in a secure place for the whole retention period.
• When you change it. Give another 30 days' written notice (163.5(b)(3)). If CBP finds the method out of line, it can order you to stop within 30 days unless you show it has been fixed (163.5(b)(5)).

Two limits are easy to miss. Records about goods under seizure or detention, or about a matter under inquiry, investigation or a proceeding, can be ordered kept in their original form (163.5(b)(1)). And the software needed to read electronic data is itself a record under 163.1(a), so switching off an old ERP or document archive is a recordkeeping decision: move the entry-related data into a format you can still open, or keep a working read-only copy, before the license ends.

What does the Recordkeeping Compliance Program change?

The program in 19 CFR 163.12 is voluntary. A certified recordkeeper that fails to produce a demanded entry record, is generally in compliance with the program, and whose failure was neither willful nor repeated receives a written notice of violation instead of a monetary penalty (163.12(d)). Certification requires showing, among other things in 163.12(b)(3), that you understand the legal requirements, have procedures to explain them to the employees involved, have procedures for preparing, keeping and producing records, have named a responsible person, have an acceptable record maintenance procedure, and have procedures to report variances and take corrective action. It does not limit CBP's power to summon records.

What should you do next on your own records?

1. Pull the broker's entry export for the last five years and add a column for each entry's retention end date: the entry date plus five years, or the later date for reconciliation and drawback records.
2. Filter the lines with a special program indicator and confirm a certification or supporting record exists for each supplier and period.
3. Match every entry to its invoice, packing list and transport document, and list the gaps.
4. Confirm you hold a copy of every binding ruling cited on an entry and a current power of attorney for each filer.
5. If you scan paper records, check that the 163.5(b) notice was sent to Regulatory Audit and that the annual test is on the calendar.
6. Before any purge, check the batch against open protests, penalty cases, CBP requests and court cases.

The same export drives the line checks described in the post-entry audit pillar. TariffSense reads broker entry exports, entry summaries and invoices in any layout and flags each line where the declared duty differs from what the measures in force on the entry date required, in both directions, with the entry date and line number attached, so the entries that need their documents first are the ones with a finding. The post-entry audit page shows what goes in and what comes back. If a CBP audit is already scheduled, the focused assessment guide covers what it tests.
