HS Code 540331

HS code 540331 is the World Customs Organization 6-digit HS 2022 subheading for "Artificial filament yarn (other than sewing thread), not put up for retail sale, including artificial monofilament of less than 67 decitex : Other yarn, single : Of viscose rayon, untwisted or with a twist not exceeding 120 turns per metre". The first two digits (54) are the chapter — Man-made filaments; strip of man-made textile materials — and digits 3-4 (5403) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 540331 include viscose rayon yarn low twist, viscose rayon filament untwisted, viscose yarn low twist, rayon yarn low twist and similar items matching of viscose rayon. 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 (540331) 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.
