Of a water absorption coefficient by weight exceeding 10%
Ceramic tiles and flags with high water absorption (exceeding 10%)
HSN 6907 23 00 (ceramic flags, paving, hearth or wall tiles, and finishing ceramics with a water absorption coefficient exceeding 10% by weight) 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. Ceramic tile products with lower water absorption coefficients fall under sibling tariff lines within Chapter 69 that may carry distinct compliance obligations.
The critical importer risk here is classification by water absorption coefficient: ceramic tiles with absorption of 10% or less are classified under separate tariff lines within Chapter 69, some of which carry Bureau of Indian Standards compliance requirements. Customs examination that determines the declared absorption coefficient to be incorrect triggers re-classification, with detention pending retrospective compliance. Obtain laboratory test documentation for water absorption before shipment and retain it for presentation at the port of entry.
