About chapter 73
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.

Codes and descriptions follow the WCO six-digit Harmonized System nomenclature. National tariff schedules extend these to 8–13 digits and set the actual duty rate, so confirm the full code for your destination country with your customs broker before filing.

Chapter 73 FAQ
What does HS code chapter 73 cover?
Chapter 73 of the Harmonized System covers: iron or steel articles. It belongs to section XV (Base Metals) and contains 26 four-digit headings, 7301–7326.
How many HS codes are in chapter 73?
Chapter 73 contains 26 four-digit headings and 124 six-digit subheadings. Countries subdivide these further (8–13 digits) in their national tariff schedules, so the full national count is larger.
Is HS code 7301 the same in every country?
Yes. The six-digit level of every code in this chapter is harmonised by the World Customs Organization and identical in all member countries. Digits beyond the sixth (for example the US 10-digit HTS or the EU 8-digit CN) are national and set the actual duty rate.
How do I choose the right code within chapter 73?
Work from the four-digit heading down: pick the heading that best matches your product, then the six-digit subheading that matches its material, form or processing. If two codes seem to fit, customs rules (the General Rules of Interpretation) decide, and when in doubt, confirm with your customs broker before filing.
