Questions

HS code 390319: common questions

What is HS code 390319?

HS code 390319 is the World Customs Organization 6-digit HS 2022 subheading for "Polymers of styrene, in primary forms : Polystyrene : Other". The first two digits (39) are the chapter — Plastics and articles thereof — and digits 3-4 (3903) are the heading. Countries add further digits (8-10) for their national tariff line.

What products fall under HS 390319?

Common products classified under 390319 include GPPS, polystyrene, crystal polystyrene, general purpose polystyrene and similar items matching polystyrene. The correct code still depends on the product's material, function and intended use.

How do I find the import duty for HS code 390319?

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 390319 the same in every country?

The first 6 digits (390319) 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.
