One kind of client worries me most: entries have always cleared, never been examined, therefore “our filings are fine.” Clearing only means not yet selected. US customs is architected so that filing accuracy was never customs’ responsibility — it is the importer’s, by statute, and the obligation has a name: reasonable care.
Informed compliance: the rules are published; getting them right is on you
Since the 1993 Customs Modernization Act, US customs runs on informed compliance: CBP owes the public clear rules (Informed Compliance Publications, rulings, guidance), and importers owe reasonable care that their declarations are correct. In plain words: everything is published, so “I didn’t know” is not a defense.
Whose duty is it? The party named Importer of Record. Hiring a broker does not transfer it — the broker is your agent, and final responsibility for the filing stays with the IOR.
The five territories of the duty
Reasonable care is not abstract; CBP’s guidance lands it on concrete questions:
- Classification: is there a basis for each HTS code? Binding Rulings requested where uncertain?
- Valuation: is dutiable value right — assists, royalties, the statutory additions all in?
- Origin: does the declared origin survive tracing — transshipment and substantial transformation supported?
- Marking: is the physical origin marking compliant?
- Permits and partner agencies: FDA, USDA, FCC — registrations and licenses current?
Penalty tiers: the same error, an order of magnitude apart
When CBP pursues a filing error, penalties scale by conduct: negligence, gross negligence, fraud — and for the same underpaid duty, the tier can move the penalty by more than an order of magnitude. The pivot is precisely whether you exercised reasonable care:
- Audit process in place, records kept, the error an isolated slip → a case for the lightest tier, even mitigation
- No process at all, the error systemic and long-lived → the heavy tiers
- The self-audit record is itself the evidence — proof you were exercising the duty, and impossible to reconstruct after the fact
One more mechanism worth knowing: Prior Disclosure — voluntarily correcting and paying before customs opens a case cuts penalty exposure dramatically.
The 10-question annual self-audit
Run these once a year, each with a record of who checked, what, and the conclusion:
- Does every HTS code used in the past year have a written classification basis?
- Is there a classification-review step when new products launch?
- Any statutory additions missed in valuation — assists (molds, designs), royalties?
- Are related-party prices supported by transfer-pricing documentation?
- Could every supplier’s origin declaration be evidenced today?
- Do product and carton origin markings meet the marking rules?
- Are FDA/USDA registrations and permits for regulated items current?
- Are entry documents, invoices and packing lists retained for the statutory period?
- Were last year’s CBP CF28 inquiries and CF29 notices answered and filed?
- Are the broker’s filings spot-checked against your records — or running unwatched?
Whatever you cannot answer is this year’s gap list.
Where SKYCARGO fits
When SKYCARGO INC holds the IOR name, this checklist is the standard we hold ourselves to: classifications with bases, valuations with add-back lists, documents retained. Where you hold the IOR name, we help bring the filing paperwork to an audit-ready state. Penalty assessment and disclosure strategy after an audit finding are legal work — consult compliance counsel or customs attorneys. B2B shipments, talk to us. (Personal parcels: Shiptw.)
Reasonable care requirements follow current CBP law and guidance. Reference only; consult compliance counsel for specific cases.
