Chapter 73 covers iron or steel articles: pipes, tubes, structural components, fasteners, tanks and household steel goods, downstream of the primary steel forms in chapter 72. Classification tip: Like chapter 72, finished steel articles (pipe, tube, fasteners) are frequent anti-dumping targets: check the current trade-remedy list for the specific product and origin country before quoting a landed cost.

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.

73.04 FAQ

Heading 73.04 covers tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel. It is part of chapter 73 (iron or steel articles), and it is subdivided into 13 six-digit subheadings — the level you actually declare.

Pick one of the 13 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 XV and to chapter 73. 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.
