Tariff and Customs Advisory: Are You Paying Too Much at the Border?

Customs valuation under U.S. .aw follows a hierarchical methodology beginning with the transaction value, defined as the price actually paid or payable for the merchandise, and proceeds through five alternative methodologies only when the transaction value cannot be used. CBP most frequently disputes transaction value when the buyer and seller are related parties or when the invoice price omits assists such as tooling, materials, or engineering services provided by the buyer. Customs valuation counsel must audit the importer's royalty agreements, intercompany pricing documentation, and assist arrangements before any CBP examination to identify and resolve the most common bases for duty underpayment and penalty assessments.

The Harmonized Tariff Schedule classifies every imported good according to a code that determines the applicable duty rate, and a change in classification by one or two subheadings can shift the duty rate dramatically or trigger Section 301 additional duties and antidumping duties that do not apply to the originally declared classification. Customs law counsel must analyze the product's composition, function, and principal use and file a binding ruling request with CBP to secure prospective certainty for future entries of the same product.

An FTA preferential tariff claim requires the importer to maintain documentation demonstrating that the goods satisfy the applicable origin criterion, whether a tariff classification change, a regional value content threshold, or a specific manufacturing process requirement, and this documentation must cover the entire supply chain from raw material sourcing through final production. Rules of origin counsel must confirm that the producer's bill of materials, cost accounting records, and production records are complete and consistent before any preferential claim is filed.

A tariff and customs advisory team managing an FTA origin verification must recognize that the importing country's customs authority evaluates all prior entries within the audit period, and a finding that goods did not satisfy the rules of origin results in denial of preferential treatment, retroactive duty assessments, and penalty exposure for each deficient entry. FTA verification counsel must immediately organize production documentation, identify gaps in cost or materials records, and prepare a written response addressing each verification inquiry with specific documentary evidence.

Merchandise subject to agency-administered import requirements must have the required permits, registrations, certifications, and documentation in place before the shipment arrives at the U.S. .ort of entry, because a shipment that arrives without the required documentation will be detained and may be refused admission. Customs compliance and enforcement counsel must identify every federal agency with jurisdiction over the product and implement a pre-shipment checklist confirming all admissibility requirements are satisfied before merchandise is loaded for export.

A CBP seizure of imported merchandise based on suspected customs fraud, intellectual property infringement, or entry of prohibited goods triggers a formal administrative process in which the importer must file a petition for relief within the applicable deadline or lose the right to contest the seizure. International trade disputes counsel must immediately assess whether the seizure is legally supported, identify any procedural defects, and file a petition for remission or mitigation presenting all available evidence contradicting the government's seizure basis.

A CBP Focused Assessment examines the importer's entry practices, classification decisions, valuation methodologies, and record-keeping systems, and the importer must designate a knowledgeable representative and produce the requested records within the specified timeframes. International trade law counsel must review all entry records for the audit period before producing them to CBP, identify any entries containing errors that should be disclosed, and assess whether filing a prior disclosure would reduce the applicable penalty to the interest-only rate.

A prior disclosure filed before CBP has initiated a formal investigation reduces the penalty for customs fraud from as much as four times the unpaid duties to only the interest on those duties, and for negligent violations reduces the penalty to a fraction of the standard amount. Administrative hearings counsel must confirm that CBP has not yet initiated a formal investigation of the specific violation, calculate the financial benefit of the penalty reduction, and prepare a prior disclosure submission legally sufficient to qualify for reduced penalty treatment.
