HS Code 330690

HS code 330690 is the World Customs Organization 6-digit HS 2022 subheading for "Preparations for oral or dental hygiene, including denture fixative pastes and powders; yarn used to clean between the teeth (dental floss), in individual retail packages : Other". The first two digits (33) are the chapter — Essential oils and resinoids; perfumery, cosmetic or toilet preparations — and digits 3-4 (3306) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 330690 include mouthwash, denture adhesive, denture cream, denture fixative, teeth whitening strips, dental rinse and similar items matching preparations for oral or dental hygiene. 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 (330690) 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.
