Meaning
Customs appraisement mechanisms determine the dutiable basis of imported merchandise by working backward from the unit price at which the imported goods are sold in the greatest aggregate quantity to unrelated domestic buyers. Recognized under the World Trade Organization Valuation Agreement, deductive value reconstructs the border transaction value when direct sales invoices between exporter and importer are absent, unverified, or distorted by corporate relationships. The calculation applies exclusively to products entering the domestic stream of commerce, terminating where post-import modifications alter the goods beyond clear accounting separation.
Aggregate Deduction
Resale data from the earliest commercial tier in the importing country forms the starting figure for the formula. When customs officials calculate deductive value, the initial reference point is the unit price at which the merchandise enters the market without prior alteration. Statutory rules require that this sale be made to parties independent of the importer, eliminating transfer-pricing distortion.
The price realized on the single largest total volume of units sold establishes the baseline, preventing isolated low-volume retail transactions from setting the customs benchmark.
Statutory Allowances
Statutory adjustments strip out all commercial and regulatory costs incurred after the physical merchandise crosses the national border. Standard markups for domestic profit, general administrative overhead, and local selling commissions earned within the destination market are deducted from the baseline resale price. Inbound freight rates, regional transport insurance, warehousing expenses, and domestic port handling fees incurred inside the importing country are removed.
National import duties, local turnover taxes, and value-added assessments paid upon entry are likewise stripped out to leave an appraised border figure.
Timeline Limits
Sales transactions utilized for backward calculation must occur within rigid statutory windows relative to import dates. Customs guidelines specify that the qualifying domestic resale must take place at or about the date of importation, usually defined as within ninety calendar days of entry. If identical or similar imported goods are not sold within this window, the calculation moves to sales occurring at the earliest date thereafter.
Inability to produce verified domestic sales records within the prescribed timeline invalidates this methodology, compelling appraisement under fallback statutory rules.
