Questions

HS code 540251: common questions

What is HS code 540251?

HS code 540251 is the World Customs Organization 6-digit HS 2022 subheading for "Synthetic filament yarn (other than sewing thread), not put up for retail sale, including synthetic monofilament of less than 67 decitex : Other yarn, single, with a twist exceeding 50 turns per metre : Of nylon or other polyamides". The first two digits (54) are the chapter — Man-made filaments; strip of man-made textile materials — and digits 3-4 (5402) are the heading. Countries add further digits (8-10) for their national tariff line.

What products fall under HS 540251?

Common products classified under 540251 include nylon twisted yarn, polyamide twisted yarn, nylon high twist yarn, polyamide high twist filament and similar items matching of nylon or other polyamides. The correct code still depends on the product's material, function and intended use.

How do I find the import duty for HS code 540251?

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.

Is HS code 540251 the same in every country?

The first 6 digits (540251) 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.

Can I trust the HS code a 1688 supplier gives me?

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.
