Valuation Basis
Customs assessment structures assign trade duties as a fixed percentage of the declared transaction value of imported merchandise. Buying organizations calculate the ad valorem tariff against the invoice value verified by customs authorities upon entry. The assessment applies to the transaction total recorded on commercial shipping documents, stopping at post-importation inland freight costs.
Calculation Method
Valuation officers compute duty amounts by multiplying the percentage rate against the appraised value of the shipment. When a mill invoices woven fabric at one hundred thousand dollars under a ten percent rate, the resulting fee equals ten thousand dollars. Fluctuations in raw material prices shift total paid duties even when physical volume stays constant.
Freight insurance inclusion depends on whether the destination port operates under free on board or cost insurance freight valuation rules.
Commercial Impact
Price fluctuations directly alter clear-to-land inventory costs under percentage duties. Importers adjust sourcing contracts when percentage rates shift between trade zones.
Entry Assessment
Declaration documents require supporting bills of lading and commercial invoices to verify declared transaction figures. Customs auditors examine unit prices during formal audits to prevent undervaluation of finished apparel consignments. Correct classification ensures duty liabilities match published schedule rates across all shipping manifests.
