7904.00 Zinc; bars, rods, profiles and wire
A full HS code. These six digits are what goes on a customs declaration, and they mean the same thing in every country that uses the Harmonized System.
Section XV, Base Metals — iron, steel, copper, aluminium, other base metals and articles thereof.
- 79 Chapter Zinc and articles thereof
- 04 Heading Zinc; bars, rods, profiles and wire
- 00 Subheading Zinc; bars, rods, profiles and wire
Chapter 79 covers zinc and articles thereof: refined zinc, zinc alloys and zinc products, widely used for galvanizing steel. Classification tip: Zinc classification splits mainly by purity grade and alloy composition, which matters because galvanizing-grade zinc and die-casting alloy zinc are priced and traded quite differently.
All of chapter 79The 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.

7904.00 covers zinc; bars, rods, profiles and wire. It sits under heading 79.04 (zinc; bars, rods, profiles and wire) in chapter 79, Section XV of the Harmonized System.
It is the international part of it. Six digits are the same in every country that applies the Harmonized System; the importing country then extends them to eight or ten for its own tariff and statistics. Declare 7904.00 plus whatever national digits the destination’s tariff schedule adds to it.
The General Rules of Interpretation, read together with the notes to Section XV and to chapter 79. 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.
