Containing by weight less than 99.99% of zinc
Unwrought zinc, less than 99.99% purity by weight
HSN 7901 12 00 (unwrought zinc containing less than 99.99% by weight of zinc) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code (IEC), bill of entry, commercial invoice, packing list. Zinc of higher purity or zinc in wrought or alloyed forms may fall under sibling tariff lines within Chapter 79 that carry distinct compliance considerations.
The absence of compliance at this tariff line does not extend to all unwrought zinc: zinc of 99.99% or greater purity is separately classified within Chapter 79 and may attract different regulatory treatment on re-classification. Customs officers examining purity certificates or mill test reports may re-classify a consignment to the higher-purity heading, triggering retrospective compliance and potential detention. Verify purity grade and intended use against the customs tariff declaration before relying on the absence of compliance at this line.
