Chapter 90 covers optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus; parts and accessories: lenses, cameras, medical devices, lab instruments and precision measuring equipment. It's a broad, high-value chapter spanning consumer optics through hospital equipment. Classification tip: Medical devices in this chapter typically require separate regulatory clearance (FDA, CE marking, or the destination country's equivalent) before import approval, independent of and in addition to the HS classification.

The wording above is the Harmonized System nomenclature as published by the World Customs Organization, HS 2022 edition. It is a classification reference, not a tariff: it carries no duty rates, and it stops at six digits — the importing country adds its own beyond that.

Classification is decided by the General Rules of Interpretation and the section and chapter notes, and it is the importing country’s customs authority that makes it binding.

90.01 FAQ

Heading 90.01 covers optical fibres and optical fibre bundles; optical fibre cables not of heading no. 8544; sheets, plates of polarising material; lenses, prisms, mirrors, of any material; unmounted; not non optical glass. It is part of chapter 90 (optical, photographic, cinematographic, measuring, checking, medical or surgical instruments and apparatus; parts and accessories), and it is subdivided into 6 six-digit subheadings — the level you actually declare.

Pick one of the 6 subheadings below. Those six digits are what customs recognises internationally; the importing country may extend them to eight or ten in its own tariff schedule.

The General Rules of Interpretation, read together with the notes to Section XVIII and to chapter 90. A description that reads right is not enough on its own — the notes routinely pull goods out of the chapter they obviously belong to and put them somewhere else. Where duty or licensing turns on the answer, ask the importing country’s customs authority for a binding ruling.

A wrong or missing code is one of the common reasons customs holds a container, and a hold shows up as a milestone that stops moving. Watch for it in the container tracking app, on the air waybill in the air cargo tracker, or through the tracking API.
