HS Code 903031

HS code 903031 is the World Customs Organization 6-digit HS 2022 subheading for "Oscilloscopes, spectrum analysers and other instruments and apparatus for measuring or checking electrical quantities, excluding meters of heading 9028; instruments and apparatus for measuring or detecting alpha, beta, gamma, Xray, cosmic or other ionising radiation : Other instruments and apparatus, for measuring or checking voltage, current, resistance or power : Multimeters, without a recording device". The first two digits (90) are the chapter — Optical, photographic, measuring, medical or surgical instruments — and digits 3-4 (9030) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 903031 include multimeter, voltmeter, ammeter, ohmmeter, digital multimeter and similar items matching multimeters. The correct code still depends on the product's material, function and intended use.

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.

The first 6 digits (903031) 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.

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.
