Questions
HS code 283010: common questions

What is HS code 283010?
HS code 283010 is the World Customs Organization 6-digit HS 2022 subheading for "Sulphides; polysulphides, whether or not chemically defined : Sodium sulphides". The first two digits (28) are the chapter — Inorganic chemicals; compounds of precious metals and isotopes — and digits 3-4 (2830) are the heading. Countries add further digits (8-10) for their national tariff line.
What products fall under HS 283010?
Common products classified under 283010 include sodium sulfide, sodium sulphide, sulfides, sodium sulfide flake and similar items matching sodium sulphides. The correct code still depends on the product's material, function and intended use.
How do I find the import duty for HS code 283010?
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 283010 the same in every country?
The first 6 digits (283010) 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.
Is HSN code 283010 the same as HS code 283010?
Yes at the 6-digit level. India's HSN (Harmonized System of Nomenclature) uses the same WCO base, so HSN 283010 covers the same "sodium sulphides" scope; India then extends it to 8 digits for GST and customs. Check the Indian Customs tariff (CBIC) for the full national line.
