HS Code 681591

HS code 681591 is the World Customs Organization 6-digit HS 2022 subheading for "Articles of stone or of other mineral substances (including carbon fibres, articles of carbon fibres and articles of peat), not elsewhere specified or included : Other articles : Containing magnesite, dolomite or chromite". The first two digits (68) are the chapter — Articles of stone, plaster, cement, asbestos, mica or similar materials — and digits 3-4 (6815) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 681591 include magnesite articles, dolomite products, chromite refractories, magnesite bricks, chromite bricks and similar items matching containing magnesite. 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 (681591) 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.
