Questions
HS code 550931: common questions
What is HS code 550931?

The first two digits (55) are the chapter — Man-made staple fibres — and digits 3-4 (5509) are the heading. Countries add further digits (8-10) for their national tariff line.
What products fall under HS 550931?
Common products classified under 550931 include acrylic single yarn, modacrylic single yarn, 100% acrylic yarn, acrylic spun yarn and similar items matching single yarn. The correct code still depends on the product's material, function and intended use.
How do I find the import duty for HS code 550931?
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 550931 the same in every country?
The first 6 digits (550931) 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.
