"Reasonable Care" Under 19 U.S.C. § 1484: What CBP Actually Expects You to Document

Under 19 U.S.C. § 1484, reasonable care requires importers of record to follow reliable procedures when declaring merchandise classification, customs value, origin, and other entry information to U.S. Customs and Border Protection (CBP). Importers must be able to demonstrate how decisions were made, what information was verified, and which compliance checks were completed at the time of entry.

Evidence of reasonable care includes documented classification rationales, valuation records, supplier verification, broker entry reviews, and internal compliance procedures. These records become particularly important during CBP audits and negligence penalty proceedings under 19 U.S.C. § 1592(e)(4), where importers may need to prove that a materially false statement or omission did not result from negligence.

What § 1484 Actually Requires

The duty attaches to the importer of record and to two distinct acts. Under 19 U.S.C. § 1484(a)(1), the importer of record must, using reasonable care, make entry by filing what CBP needs to decide whether goods may be released, and complete the entry by filing the declared value, classification and rate of duty, plus whatever else CBP needs to assess duties, collect accurate statistics, and determine whether any other applicable requirement of law is met.

Three features of that text get misread routinely.

• The standard governs manner, not outcome: The statute does not say the importer must be correct. It says the importer must use reasonable care in filing. CBP's own guidance draws the division explicitly: the importer uses reasonable care to enter, classify and value, and CBP is then responsible for fixing the final classification and value.

• The duty runs to the importer of record personally: The acts may be performed by an agent authorized in writing, but the obligation is imposed on the importer, not transferred to the broker. Designating a licensed broker changes who files. It does not change who owes the duty.

• The third limb is broader than duty: Because the statute reaches information needed to determine whether any other applicable requirement of law is met, reasonable care pulls in partner-agency admissibility, quota and visa, AD/CVD scope reporting, intellectual property, marking, and forced labor. The statistical limb has independent force through § 1484(f), which requires an accurate statement of the kinds, quantities and values of merchandise. An error that costs the government no revenue at all can still be a reasonable-care failure on statistics alone.

Why the Standard Is an Evidentiary Posture

Section 1592(e)(4) allocates the burdens: where a penalty is based on negligence, the government must establish the act or omission constituting the violation, while the alleged violator bears the burden of proving that the act or omission did not result from negligence. The Federal Circuit’s formulation in United States v. Ford Motor Co. is the standard citation.

• Government’s burden: CBP must show that a materially false statement or omission occurred.

• Importer’s burden: Once CBP does so, the defendant must affirmatively demonstrate that it exercised reasonable care.

• Materiality threshold: A statement or omission is material if it has the natural tendency to influence, or is capable of influencing, agency action.

• What materiality covers: The test applies across classification, appraisement, admissibility, duty liability, and the collection of accurate trade statistics.

• No “but for” requirement: An error can be material even if it did not actually change CBP’s decision, so long as it could have influenced it.

For a compliance function, the operative question is therefore not “what should we be doing?” but “what will we be able to produce?” Everything below follows from that reframing, and it is why classification errors carry compliance risk beyond the duty at stake on any single entry.

The Binding Definition, and the One CBP Disclaims

Two documents dominate discussion of this standard, and only one of them binds.

• CBP’s nonbinding guidance: CBP's Informed Compliance Publication Reasonable Care is the most-cited source and the one CBP most emphatically disclaims. It concedes that the responsibility "defies easy explanation" and that neither CBP nor the importing community can develop a foolproof checklist covering every transaction. Its disclaimer is worth quoting rather than paraphrasing in any internal memo that relies on it: the information "has no legal, binding or precedential effect on CBP or the importing community."

• The binding standard: The binding text sits in 19 CFR Part 171, Appendix B, paragraph (D)(6). It requires all parties to exercise reasonable care in fulfilling entry responsibilities, including providing a classification and value, furnishing information sufficient for CBP to determine final classification and valuation, and "taking measures that will lead to and assure the preparation of accurate documentation." That last clause is a process obligation independent of accuracy, and it is the hook on which documentation requirements hang.

Appendix B also names the only two failures singled out in regulation: CBP may consider failure to follow a binding ruling a lack of reasonable care, and unreasonable classification will be considered a lack of care.

Under 19 CFR Part 171, Appendix B, CBP "may consider" failure to follow a binding ruling a lack of reasonable care. However, the Mod Act legislative history explicitly states that "the failure to follow a binding ruling is a lack of reasonable care," a position cited by the Court of International Trade (CIT).

There is one further trap. CBP's own Importing Into the United States cautions that reliance solely on the general information in that pamphlet may not be considered reasonable care. General guidance is not a safe harbor, and neither is hiring an expert: the CIT held in Optrex that consulting counsel "is evidence of compliance; it is not compliance in itself."

What the Record Has to Contain

The ICP's recurring phrase across every topical section is "reliable procedures." It asks not whether the importer reached the right answer but whether a procedure exists, is followed, and produces retrievable output. Mapped to entry elements, that means specific artifacts.

One adjacent duty belongs in the same file. Under § 1485(a), every importer making entry declares under oath that it will produce at once any invoice, paper, letter, document or information received showing that declared prices or statements are not true or correct. That obligation is affirmative and continuing, carries no dollar threshold, and is not bounded by the post-summary correction window. A procedure that routes late-arriving contrary information to the customs function is therefore evidence of care in its own right.

Classification: A written rationale per HTS number actually used, showing the GRI path and the sources consulted. A dated CROSS rulings search record, because Optrex turned partly on on-point rulings and court decisions the importer could not show it had reckoned with, which defeated its claim of mere professional disagreement. Any Part 177 ruling obtained, plus evidence it was followed and brought to CBP's attention. Lab reports or engineering specifications where composition drives the code. And a documented periodic re-review against tariff amendments and new rulings, since a ruling letter is subject to modification or revocation without notice to anyone other than its addressee.

Valuation: The complete transaction file the ICP names: purchase orders, invoices, sales agreements, shipping documents, and proof of payment. A documented additions analysis covering assists, commissions, indirect payments, rebates, royalties and proceeds. Related-party test documentation where applicable. First-sale substantiation showing a bona fide arm's-length sale with goods clearly destined to the United States at the time of sale. And a standing procedure to capture retroactive price adjustments, which is the Ford lesson in artifact form: contract terms providing for post-entry price adjustment, combined with no mechanism routing change orders to the customs function, produced a material omission.

Origin, preference and marking: Supplier declarations, manufacturer's affidavits and milling certificates, plus the underlying production records. Critically, evidence of an affirmative verification step rather than reliance on assertion. In Golden Ship Trading the CIT drew the line directly: there is a distinct difference between legitimately attempting to verify entry information and blindly relying on the exporter's assertions, and reliance on the exporter and the broker does not remove the obligation. The attempt is what gets graded.

AD/CVD and other agencies: A documented scope analysis against active orders, with case-number reporting on the entry summary. CBP is unforgiving on the mechanics: an entry summary for merchandise subject to an order that does not contain the identifying number will be rejected. Partner-agency permits obtained prior to or upon entry, and exclusion-order screening records.

Forced labor: Supplier vetting questionnaires, contract clauses prohibiting forced labor with corrective-action timeframes and termination consequences, internal audit reports, and third-party unannounced audits. All four are ICP items added in the September 2017 revision, alongside a documented screening step against CBP's withhold release orders and the Department of Labor's list of at-risk country and commodity pairs.

The Governance Artifacts CBP Asks For By Name

Beyond entry-element evidence, CBP's Focused Assessment program requests specific documents, and its Pre-Assessment Survey Questionnaire asks specific questions. Building to that list is the cheapest way to know whether a program would survive contact.

Auditors assess whether internal control is documented, logical, reasonably complete, and likely to prevent or detect noncompliance, and whether it has been placed into operation. Design and operation are graded separately, which is why an unread manual scores badly on both counts.

Where Importers Actually Fail

The decided cases cluster around four fact patterns, and none of them turn on getting classification wrong in isolation.

1. Advice obtained and disregarded: In Optrex, discovery produced documents showing the importer sought but disregarded counsel's advice to classify under a different heading, while contemporaneously keeping a separate account reflecting the higher duty rate and paying the lower one. The CIT found negligence and assessed penalties at one and a half times the unpaid duties.

2. Reliance without verification: Golden Ship Trading found a failure of reasonable care where the importer did not verify the information in the entry documents. Commentators reading the case concluded that had she attempted to check the exporter's credentials and operations, the outcome might have differed.

3. Scale and duration: In Sterling Footwear, the CIT found gross negligence across 337 entries over three years, with $1,566,824.85 in unpaid duties.

4. A clerical error that became a pattern: There is no violation where falsity is due solely to clerical error, and unintentional electronic repetition of an initial error generally does not constitute a pattern. But the safe harbor closes on notice: once CBP draws attention to the repetition, subsequent failure to correct it can constitute a violation, and repetition over a significant period or across many entries can itself indicate a pattern.

The gross-negligence line is a difference in mental state, not in magnitude. Negligence is failure to exercise the care and competence expected of a person in the same circumstances. Gross negligence requires actual knowledge of, or wanton disregard for, the relevant facts. Penalty ceilings scale accordingly: for negligence, the lesser of domestic value or twice the deprived duties; for gross negligence, the lesser of domestic value or four times.

Building the File Before You Need It

The practical implication of a burden-shifting standard is that documentation has to be contemporaneous. A rationale prepared only after a CF-28 arrives does not demonstrate that reasonable care was exercised at entry. The more persuasive evidence is documentation created before the inquiry, with dates showing the analysis was already in place. 

Three habits produce most of the value. Record the reasoning, not just the conclusion, so a file shows the GRI path and the sources consulted rather than a bare code. Capture the negative results too, since a documented CROSS search that found nothing on point is stronger evidence than no search record at all. And route contract mechanisms that change value after entry, price adjustments, rebates, retroactive discounts, to the customs function by design rather than by luck, because that gap is precisely what converted post-entry knowledge into liability in Ford. Teams that treat classification as a decision record rather than a data field find that the same file answers an auditor, a penalty officer and an inquiry about a wrong code without reconstruction.

FAQs

Does using a licensed customs broker satisfy reasonable care?

No, the statute permits filing through an agent authorized in writing, but the reasonable-care obligation sits with the importer of record and is not transferred. The CIT has held that reliance on the exporter and broker does not remove the obligation to ensure entry statements are correct. A broker changes who files, not who answers.

Is following CBP's Informed Compliance Publication enough?

Not on its own. CBP states the publication has no legal, binding or precedential effect, and separately cautions that reliance solely on general guidance may not be considered reasonable care. The binding standard sits in 19 CFR Part 171, Appendix B. Treat the ICP as a diagnostic, not a safe harbor.

If a classification error costs the government nothing, is it still a problem?

Potentially yes. Section 1484 covers information needed to collect accurate statistics, an independent limb with its own force under § 1484(f). Materiality is the natural tendency to influence agency action, with no "but for" test, and trade statistics is a listed material category. Revenue-neutral errors stay exposed.

Does an honest disagreement about classification count as a lack of care?

Not by itself. The legislative history states that an honest, good-faith professional disagreement on a technical matter is not a lack of reasonable care unless it has no reasonable basis. The CIT has applied that, finding reasonable care where an importer acted on counsel's advice. Disregarding advice you obtained is the pattern that fails.
