HS code 283210: common questions

What is HS code 283210?

HS code 283210 is the World Customs Organization 6-digit HS 2022 subheading for "Sulphites; thiosulphates : Sodium sulphites". The first two digits (28) are the chapter — Inorganic chemicals; compounds of precious metals and isotopes — and digits 3-4 (2832) are the heading. Countries add further digits (8-10) for their national tariff line.

What products fall under HS 283210?

Common products classified under 283210 include sodium sulfite, sodium sulphite, sulfite, preservative and similar items matching sodium sulphites. The correct code still depends on the product's material, function and intended use.

How do I find the import duty for HS code 283210?

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 283210 the same in every country?

The first 6 digits (283210) 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.
