Fire clay, other than commonly traded grades
HSN 2508 30 90 (fire clay — other than commonly traded grades) 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. Other clays and refractory materials within Chapter 25 — including chamotte, mullite, and calcined forms — may be classified under distinct tariff lines that attract separate compliance scrutiny.
The absence of compliance at this tariff line does not extend to all refractory clay products: calcined fire clay, chamotte, and dinas earths are separately classified within Chapter 25, and refractory articles manufactured from fire clay fall under Chapter 69 where quality obligations may apply. Re-classification on customs examination — on grounds of calcination state, alumina content, or end-use designation — triggers retrospective compliance, including detention pending resolution. Verify product specification, processing state, and intended use against the customs tariff before relying on the absence of compliance.
