Meaning
Customs valuation additions or deductions applied to declared invoice prices determine the final dutiable import value of imported merchandise. Under Article 11 of the Regulations on Import and Export Duties, customs officers require a transaction value adjustment when declared prices exclude statutory mandatory additions or include non-dutiable cost components. Dutiable additions encompass offshore freight, transport insurance, royalties, engineering design fees, and seller profit shares generated from downstream resales.
Statutory exclusions permit deducting post-importation construction costs, internal domestic transport fees, and domestic import taxes from the total customs assessment base.
Statutory Additions
Customs evaluators inspect trade contracts to identify implicit value components that must be added to declared invoice totals. License fees, software development costs, and foreign engineering assistance provided free of charge by foreign buyers must be quantified and added to import values. Unreported royalty payments linked to imported goods trigger retroactive duty adjustments and non-compliance fines.
Operational Verification
Customs officers verify transaction values by analyzing commercial contract sets, cross-border payment receipts, and enterprise financial records. When declared transaction values appear artificially reduced due to related-party relationships, customs officials reject the invoice price. Evaluators apply alternative valuation standards to calculate revised customs duties based on independent market benchmarks.
Customs Obligation
Importers must disclose all mandatory price additions on official customs declaration forms during port entry clearance. Failing to declare mandatory transaction value adjustments constitutes tax misreporting under customs administrative regulations. Additional duties assessed during customs audits must be paid within statutory administrative deadlines alongside accrued penalty interest.
The transaction value adjustment mechanism establishes accurate customs valuation bases by aligning declared invoice prices with statutory valuation laws.
