Semi-plastic

Semi-plastic fire clay, a refractory mineral

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2508 30 20 (semi-plastic fire clay) 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 under Chapter 25 — including chamotte, mullite, and calcined grades — occupy distinct tariff lines that may carry separate compliance considerations.

No partner government agency notification covers this tariff line.

A word of counsel

Semi-plastic fire clay sits within a heading that spans several mineralogically distinct refractory materials; misidentification of grade or calcination state can shift classification to a sibling line with different compliance standing. Customs re-classification on examination triggers retrospective duty recovery and potential detention pending resolution. Importers should document purity, plasticity index, and intended refractory end-use before filing the bill of entry.
