HS Code 680690

HS code 680690 is the World Customs Organization 6-digit HS 2022 subheading for "Slagwool, rockwool and similar mineral wools; exfoliated vermiculite, expanded clays, foamed slag and similar expanded mineral materials; mixtures and articles of heatinsulating, soundinsulating or soundabsorbing mineral materials, other than those of heading 6811 or 6812 or of Chapter 69 : Other". The first two digits (68) are the chapter — Articles of stone, plaster, cement, asbestos, mica or similar materials — and digits 3-4 (6806) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 680690 include insulation board, acoustic panel, mineral wool board, insulation blanket, soundproofing material and similar items matching slagwool. 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 (680690) 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.
