HS Code 690320

HS code 690320 is the World Customs Organization 6-digit HS 2022 subheading for "Other refractory ceramic goods (for example, retorts, crucibles, muffles, nozzles, plugs, supports, cupels, tubes, pipes, sheaths and rods), other than those of siliceous fossil meals or of similar siliceous earths : Containing, by weight, more than 50 % of alumina (Al2O3) or of a mixture or compound of alumina and of silica (SiO2)". The first two digits (69) are the chapter — Ceramic products — and digits 3-4 (6903) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 690320 include alumina crucibles, high alumina ceramics, alumina tubes, mullite ceramics, silica crucibles, aluminum oxide refractories and similar items matching containing. The correct code still depends on the product's material, function and intended use.

Duty is set by the destination country, not by the 6-digit HS code alone. Start from the official tariff of your market — USITC HTS (US), TARIC / Access2Markets (EU), GOV.UK Trade Tariff (UK), CBSA (Canada), ABF (Australia) or Singapore Customs — and look up the full national code with China as the country of origin.

The first 6 digits (690320) are the same worldwide under the WCO Harmonized System. Beyond that, each country extends the code (HTS in the US, TARIC in the EU, etc.) and sets its own duty and tax rates.

Treat a supplier-provided code as a clue, not a final classification. It can be incomplete, China-export-specific, or mismatched to your destination's rules. Verify against the official tariff and your product's actual material and use.
