<h1>Customs valuation rules impose additional importer obligations and automated checks for identified classes of potentially undervalued imported goods.</h1> The rules permit the Board to notify identified goods-classes of imports suspected to be undervalued-and require committees to examine written references and value trends. The Evaluation Committee must report specified parameters including 8 digit HS codes, brands, a precautionary unit value, Unique Quantity Code, technical specifications, additional importer obligations (such as manufacturer invoices, test or expert reports, costing) and checks to be exercised; notifications apply for 1-2 years and are implemented via the Customs Automated System, with review and specified exceptions.
