TUNGSTEN ORES AND CONCENTRATES
Tungsten ores and concentrates for industrial processing
HSN 2611 00 00 (Tungsten ores and concentrates) 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. Downstream tungsten products — including ferro-tungsten, tungsten powder, and finished tungsten articles — are classified in other chapters and may carry distinct compliance requirements.
The absence of compliance at this tariff line applies specifically to unprocessed ores and concentrates; tungsten in other forms, such as ferro-tungsten under Chapter 72 or tungsten carbide and powder under Chapter 28, falls under separate tariff lines that may attract their own regulatory obligations. Customs examination may prompt re-classification if the declared product has undergone processing beyond the ore or concentrate stage, triggering retrospective compliance and potential detention. Verify the degree of processing and precise product specification — tungsten trioxide content, concentrate grade — before filing.
