Questions
HS code 903300: common questions
What is HS code 903300?
HS code 903300 is the World Customs Organization 6-digit HS 2022 subheading for "Parts and accessories (not specified or included elsewhere in this chapter) for machines, appliances, instruments or apparatus of Chapter 90". The first two digits (90) are the chapter — Optical, photographic, measuring, medical or surgical instruments — and digits 3-4 (9033) are the heading. Countries add further digits (8-10) for their national tariff line.
What products fall under HS 903300?
Common products classified under 903300 include optical instrument parts, measuring instrument accessories, laboratory equipment parts, scientific instrument components, spare parts for test equipment and similar items matching parts and accessories. The correct code still depends on the product's material, function and intended use.
How do I find the import duty for HS code 903300?
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 903300 the same in every country?
The first 6 digits (903300) 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.
