Valuation Rule
Legal tariff methodologies establish the taxable monetary value of imported commercial merchandise for the assessment of ad valorem customs duties and import taxes. Customs valuation applies primary transaction value criteria, secondary pricing benchmarks and statutory additions to declared commercial invoices at border checkpoints. The term excludes non-tariff customs clearance procedures such as sanitary inspections, rules of origin determinations or security screenings.
Cost Adjustment
Border authorities rely primarily on the transaction value method defined under the World Trade Organization Valuation Agreement, which uses the total price paid or payable for the goods when sold for export. Importers must declare and add statutory additions to the invoice price, including freight and insurance up to the border, selling commissions, royalties, licensing fees and engineering assists supplied by the buyer. If the transaction value is rejected due to related-party price distortions, authorities apply sequential alternate methods based on identical goods, similar goods, deductive sales prices or computed production costs.
Documentation audits review transfer pricing studies, transport contracts and general ledger accounts to verify the accuracy of declared invoice values.
Audit Liability
Undervaluation findings result in retroactive duty assessments, punitive financial fines, interest penalties and heightened commercial cargo inspection frequencies. Customs valuation determines the direct tax liability on cross-border merchandise flows.
