Questions
HS code 901730: common questions
What is HS code 901730?
HS code 901730 is the World Customs Organization 6-digit HS 2022 subheading for "Drawing, markingout or mathematical calculating instruments (for example, drafting machines, pantographs, protractors, drawing sets, slide rules, disc calculators); instruments for measuring length, for use in the hand (for example, measuring rods and tapes, micrometers, callipers), not specified or included elsewhere in this chapter : Micrometers, callipers and gauges". The first two digits (90) are the chapter — Optical, photographic, measuring, medical or surgical instruments — and digits 3-4 (9017) are the heading. Countries add further digits (8-10) for their national tariff line.
What products fall under HS 901730?
Common products classified under 901730 include micrometer, caliper, gauge, digital caliper, depth gauge, vernier caliper and similar items matching micrometers, callipers and gauges. The correct code still depends on the product's material, function and intended use.
How do I find the import duty for HS code 901730?
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 901730 the same in every country?
The first 6 digits (901730) 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.
