Transaction value of identical goods governs import valuation, with adjustments for level, quantity and transport costs. The customs value of imported goods is to be determined by the transaction value of identical goods sold for export to India at or about the same time, excluding provisionally assessed values. If identical goods are not sold at the same commercial level or quantity, transaction values at different levels or quantities may be used after adjustments for commercial level and quantity supported by demonstrated evidence; transport-related cost differences also require adjustment. Where multiple transaction values exist, the lowest value is used.
