HS Code 540419

HS code 540419 is the World Customs Organization 6-digit HS 2022 subheading for "Synthetic monofilament of 67 decitex or more and of which no crosssectional dimension exceeds 1 mm; strip and the like (for example, artificial straw), of synthetic textile materials, of an apparent width not exceeding 5 mm : Monofilament : Other". The first two digits (54) are the chapter — Man-made filaments; strip of man-made textile materials — and digits 3-4 (5404) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 540419 include synthetic monofilament, monofilament yarn, synthetic thread, monofilament string, plastic monofilament and similar items matching monofilament. 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 (540419) 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.
