Customs valuation rules clarify inclusion of royalties and transport charges in import value and rejection procedure. The Circular explains key changes under the Customs Valuation Rules, 2007: Transaction value is defined; provisos bar use of provisionally assessed values for determining identical or similar goods; the residual valuation method is aligned with international provisions. Explanations require inclusion of royalties or licence fees in value even when linked to post importation processes, expand transport cost to cover demurrage and lighterage/barge charges to the place of importation, and clarify that the rejection provision sets a procedure for rejecting declared value while allowing acceptance after consultation.
