1. INTRODUCTION
Reasonable care is one of the most important compliance standards in U.S. importing, because it places the legal responsibility for accurate entry information on the importer of record. Under 19 U.S.C. § 1484, the importer must use reasonable care when making entry and when completing the entry with the declared value, tariff classification, and applicable rate of duty. In practice, that standard affects release, admissibility, duty assessment, recordkeeping, audit exposure, and penalty risk.
For importers, reasonable care is not just a legal phrase. It is an operating expectation. CBP’s informed compliance framework expects importers to understand their products, maintain supporting records, and provide accurate information to CBP and partner government agencies. A failure to do so can delay cargo, trigger Requests for Information, increase exam activity, and, in more serious cases, support negligence based penalty actions.
2. REGULATORY AND LEGAL CONTEXT
The legal foundation for reasonable care is the Customs Modernization framework reflected in 19 U.S.C. § 1484. That statute requires the importer of record, using reasonable care, to make entry and complete the entry by filing information necessary for CBP to determine admissibility, properly assess duties, and collect accurate trade statistics.
CBP reinforces this standard through its Informed Compliance Publications, including the current January 7, 2026 edition of What Every Member of the Trade Community Should Know About: Reasonable Care. CBP also explains in its commercial importing guidance that reasonable care is an explicit importer responsibility and that CBP and the trade community share responsibility for compliance.
Reasonable care also connects directly to recordkeeping. Under 19 CFR Part 163, persons required to maintain import records must keep required records and make them available for examination; as a general rule, records relating to an entry must be kept for five years from the date of entry.
Where import information is false, omitted, or unsupported, the issue can move beyond operational noncompliance into penalty exposure under 19 U.S.C. § 1592.
That statute establishes separate penalty standards for fraud, gross negligence, and negligence. For negligence, the maximum penalty can reach the lesser of the domestic value of the merchandise or two times the lawful duties, taxes, and fees of which the United States is or may be deprived; if the violation did not affect duties, the maximum can be 20 percent of the dutiable value.
3. WHAT CBP OR REGULATORS EXPECT
From a practical standpoint, CBP expects the importer to be able to support the core elements of the entry with contemporaneous records and internal controls. That typically includes:
- Correct importer of record identification and current CBP registration information.
- Accurate tariff classification based on the product’s actual characteristics, use, and legal notes.
- Supportable customs value, including review of assists, royalties, commissions, related party issues, and other additions or adjustments where applicable.
- Correct country of origin and marking analysis, where required.
- Admissibility review for goods subject to FDA, USDA, or other agency requirements.
- Proper use of special tariff claims, exemptions, and free trade agreement claims only when documentary support exists.
- Records retained for the required period and retrievable for audit, inquiry, or verification.
CBP also expects importers to use available compliance tools before cargo arrives. That includes reviewing Informed Compliance Publications, consulting the CBP rulings program when classification or origin treatment is uncertain, and ensuring that data given to a customs broker is complete and accurate. CBP’s guidance makes clear that the importer remains responsible for knowing the requirements applicable to the importation.
4. COMMON COMPLIANCE GAPS
Several recurring gaps tend to undermine reasonable care programs.
Overreliance on suppliers. Importers often accept vendor descriptions, origin statements, or valuation assumptions without independent review. That is risky where the supplier’s commercial documentation does not align with U.S. customs requirements. CBP’s reasonable care standard requires more than passive reliance.
Assuming the customs broker owns the legal risk. A licensed customs broker plays an important compliance role, but the importer of record generally remains responsible for the underlying accuracy of entry data unless the broker is itself acting as importer of record in a given transaction.
Weak product master data. Classification, PGA flags, origin, and valuation issues often start with incomplete or inconsistent product records. If the importer cannot clearly describe the product, components, function, and sourcing path, entry accuracy becomes harder to defend. This is especially significant for classification and admissibility analysis.
Insufficient recordkeeping discipline. Part 163 recordkeeping obligations are not satisfied by scattered emails or incomplete supplier files. Importers need a system that preserves, indexes, and retrieves records in a usable form for CBP review.
Late correction culture. Problems identified after entry should be evaluated promptly. In appropriate cases, prior disclosure may reduce penalty consequences if made before, or without knowledge of, a formal investigation. That does not eliminate the duty exposure itself, but it can materially change the penalty posture.
5. HOW S.J. STILE ASSOCIATES HELPS
S. J. Stile Associates Ltd., Trusted Customs Brokers Since 1968, supports importers by helping translate reasonable care from a legal standard into an operational discipline.
Our role is not to replace the importer’s legal responsibility. Rather, it is to help clients strengthen the quality of the information that supports entry filing and post entry compliance. That includes:
- Reviewing commercial documents for classification, valuation, and origin consistency.
- Identifying documentation gaps before entry transmission.
- Helping importers organize records needed for audit readiness and post entry review.
- Escalating issues that may require legal interpretation, a binding ruling request, or corrective action.
- Supporting communication workflows when CBP requests additional information.
- Helping clients align internal purchasing, logistics, finance, and compliance teams around the data CBP expects to see.
For many importers, the most effective reasonable care program is the one that is documented, repeatable, and integrated into normal business processes before CBP asks questions.
6. FREQUENTLY ASKED QUESTIONS
1. Does hiring a customs broker satisfy the importer’s reasonable care obligation?
No. A broker can prepare and transmit entries, but the importer of record remains responsible for the accuracy and completeness of the information underlying the entry, unless the broker is itself acting as importer of record for that transaction.
2. What information must an importer be able to support?
At a minimum, the importer should be able to support admissibility, value, tariff classification, rate of duty, country of origin, and any special claim made on the entry. Those elements are central to the statutory entry obligation under 19 U.S.C. § 1484.
3. How long must import records be kept?
Under 19 CFR § 163.4, the general rule is five years from the date of entry for entry related records, unless a specific exception applies.
4. What happens if CBP concludes the importer did not exercise reasonable care?
Consequences can include cargo delays, intensified review, record demands, duty recovery, and potential penalty exposure under 19 U.S.C. § 1592, depending on the facts and the level of culpability found by CBP.
5. Can an importer correct an issue after discovering it?
Potentially, yes. Importers should evaluate issues promptly. In certain circumstances, a prior disclosure made before, or without knowledge of, the commencement of a formal investigation can significantly reduce monetary penalty exposure, though duties, taxes, and fees still must be restored where owed.
6. When should an importer seek a binding ruling?
A binding ruling should be considered when classification or other customs treatment is uncertain and the importer needs an official pre entry determination from CBP to support a defensible compliance position. nformation are being requested.

8. FINAL THOUGHTS
Reasonable care is not a vague best practice. It is a legal and operational standard that governs how importers prepare, support, and defend their entries. Importers are expected to know their products, understand the entry data being transmitted in their name, maintain records, and correct problems when discovered. When those controls are weak, customs risk rises quickly. When those controls are documented and disciplined, importers are in a much stronger position to manage release, audit, and penalty exposure.
