HS Code 690100

HS code 690100 is the World Customs Organization 6-digit HS 2022 subheading for "Bricks, blocks, tiles and other ceramic goods of siliceous fossil meals (for example, kieselguhr, tripolite or diatomite) or of similar siliceous earths". The first two digits (69) are the chapter — Ceramic products — and digits 3-4 (6901) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 690100 include diatomaceous earth bricks, kieselguhr bricks, diatomite blocks, tripolite tiles, siliceous earth bricks and similar items matching bricks. 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 (690100) 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.
