Clay graphite stopper heads
Clay graphite stopper heads for refractory applications
HSN 6902 90 40 (clay graphite stopper heads) 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. Other refractory ceramic goods within Chapter 69 — particularly those covered by specific IS standards for refractory bricks and shapes — may carry compliance obligations at neighbouring tariff lines.
The absence of compliance at this tariff line does not extend to all refractory ceramic goods in Chapter 69; refractory bricks, blocks, and tiles classified under other headings within the chapter may be subject to Quality Control Orders or IS standards based on composition and end-use. Re-classification on customs examination — for instance, where a stopper head is assessed as a generic refractory shape rather than a clay graphite article — triggers retrospective compliance and potential detention. Verify product composition, graphite content, and intended application against the customs tariff before import.
