Ceramic grade
Kaolin and kaolinic clays, ceramic grade
HSN 2507 00 22 (ceramic-grade kaolin and kaolinic clays, whether or not calcined) 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, bill of entry, commercial invoice, packing list. Kaolin destined for uses other than ceramics — such as paper-coating or refractory applications — may be classified under a sibling tariff line within Chapter 25 that attracts different treatment.
The absence of compliance at this tariff line is specific to ceramic-grade kaolin; other grades and uses — paper grade, refractory grade, or calcined kaolin supplied as a filler or coating pigment — are classified separately within Chapter 25 and may carry distinct obligations. Customs re-classification on examination, based on purity, particle-size distribution, or declared end-use, triggers retrospective compliance and detention pending resolution. Importers should ensure the grade designation on the commercial invoice and technical data sheet aligns precisely with the tariff-line description.
