Identified goods valuation controls: Board may require unique codes and extra declaration checks to address suspected undervaluation. The Rules create a procedure for the Board to specify classes or subsets of imported goods as identified goods where undervaluation is suspected, based on written references and committee review. A Screening Committee performs preliminary scrutiny and confirms reports; an Evaluation Committee conducts detailed analysis and issues reasoned reports specifying HS Code, Unique Quantity Code, technical particulars, precautionary unit value, additional importer obligations and checks, and an initial validity period. Importers must declare required particulars and fulfill obligations on the Customs Automated System, with prescribed compliance timelines and review mechanisms; specified exceptions apply.
