1. Start with the Filed Entry and Its Source Records
Under 19 U.S.C. § 1484, an importer of record must use reasonable care when making entry and providing information used for classification, valuation, and duty assessment. Review what was submitted to CBP and trace it to the records supporting the filing.
Compare the Entry with Commercial Documents
Compare the entry summary with the commercial invoice, purchase order, packing list, bill of lading, supply agreement, and broker instructions. Differences in description, price, shipment terms, quantity, or origin may identify the issue. Using a broker does not eliminate the importer’s statutory responsibilities. Contract terms involving royalties, commissions, rebates, tooling, or later price adjustments may also affect the analysis. Related obligations are discussed under customs law.
Check Whether the Issue Reaches Earlier Entries
Classification, value, origin, admissibility, and documentation issues should be analyzed separately. If the same methodology was used for prior shipments, check whether the questioned assumption appears there as well.
2. Review Classification, Value, and Origin Separately
Classification depends primarily on the merchandise, valuation on the transaction and statutory rules, and origin on the applicable rule and production facts.
Classification Starts with the Merchandise
Compare the HTSUS provision with the product’s composition, function, design, components, and technical specifications. Technical sheets, photographs, drawings, and component information may provide better support than a broad commercial product name.
Customs Value May Include More Than the Invoice Price
Under 19 U.S.C. § 1401a, transaction value is generally the primary appraisal method when its statutory conditions are satisfied. The analysis begins with the price actually paid or payable and may require additions such as packing costs, selling commissions, assists, specified royalties, or certain resale proceeds. Compare invoices with contracts and payment records when related-party transactions, indirect payments, or later price adjustments may affect value. More detailed issues are addressed under customs valuation.
Origin Depends on Production Facts
The shipping country does not necessarily determine customs origin. Compare supplier declarations with bills of materials, manufacturing locations, processing records, and the origin rule applicable to the merchandise.
3. Match the CBP Document to the Correct Procedure
A request for information, Notice of Action, detention, liquidation, and protestable decision represent different procedural stages. Identify the document, affected entry, issue raised, and deadline before responding.
Forms 28 and 29 Serve Different Functions
CBP Form 28 may request documents or explanations concerning classification, value, origin, or admissibility. The response should connect relevant records to the specific question raised. A Form 29 Notice of Action may describe a proposed action or one already taken. Responding to a proposed adjustment differs from challenging a completed determination.
Detention Has Its Own Timeline
Under 19 U.S.C. § 1499, CBP generally must decide whether to release or detain merchandise within five days, excluding weekends and holidays, after presentation for customs examination. Unless a longer period is authorized by law, failure to make a final admissibility determination within 30 days after presentation is treated as an exclusion decision for protest purposes.
Additional Duties Should Be Traced to the Decision
A change in classification, customs value, duty rate, or another determination may increase duties owed. Identify the CBP decision that caused the additional amount rather than treating the amount itself as the legal issue. The response may depend on whether the entry remains open, has liquidated, or is already protestable. Broader corrective issues may overlap with import and trade compliance.
4. Preserve Records and Check the Review Deadline
The filing history should show what supported the entry and what changed later. This becomes important when evaluating a protest or other administrative response.
Keep the Original Record Trail
Under 19 U.S.C. § 1508 and 19 C.F.R. Part 163, many entry-related records are subject to a five-year retention period, although different rules may apply to particular records. Preserve invoices, contracts, classification materials, origin documents, payment records, and broker instructions. If a document is corrected later, keep both versions and the explanation for the change.
Protest and Court Review Have Different Deadlines
Under 19 U.S.C. § 1514, specified decisions concerning appraised value, classification, duty rate, charges, and exclusion may be protested. A protest generally must be filed within 180 days after liquidation or reliquidation or, when those events do not apply, within 180 days after the challenged decision.
If CBP denies a protest, an action contesting that denial falls within the exclusive jurisdiction of the U.S. Court of International Trade under 28 U.S.C. § 1581(a). Under 28 U.S.C. § 2636(a), the action generally must begin within 180 days after the applicable protest denial. For actions under § 1581(a), 28 U.S.C. § 2637(a) generally also requires payment of the liquidated duties, charges, or exactions before filing. The importer’s Brooklyn location does not convert the dispute into a New York state-law proceeding.
5. Frequently Asked Questions
Can an Importer Ask CBP for a Ruling Before Importing?
Yes. Under 19 C.F.R. Part 177, importers and other interested persons may request rulings on qualifying prospective customs questions. The request should accurately describe the merchandise and transaction because CBP’s analysis depends on the facts presented. A ruling differs from a protest, which challenges a decision already made.
Can an Importer Make a Prior Disclosure After Finding an Error?
Potentially. Under 19 U.S.C. § 1592(c)(4), qualifying disclosure of circumstances involving a potential § 1592 violation may receive prior-disclosure treatment when statutory requirements are satisfied. Prior disclosure differs from an ordinary correction or protest. Its availability may depend on investigation status, timing, and unpaid duties, taxes, and fees.
6. When Should a Customs Issue Be Reviewed by an Attorney?
Attorney review may become important when CBP proposes additional duties, detains or excludes merchandise, questions multiple entries, raises a potential penalty issue, or starts a review deadline. An attorney can assess whether the next step involves supplying information, correcting a filing, evaluating prior disclosure, preserving protest rights, or considering Court of International Trade review. Businesses facing an active CBP matter can also review customs compliance and enforcement.
