HS code for Cast iron scrap: 7204.10
Ferrous waste and scrap, of cast iron.
Classification of cast iron scrap under HS 7204.10
Ferrous waste and scrap of cast iron are classified under HS code 720410. This code is part of Chapter 72, which covers iron and steel in their primary forms and waste products. To qualify for this code, the material must be fit only for the recovery of metal through remelting or for use in the manufacture of chemical products. It typically consists of broken pieces of cast iron machinery, discarded pipes, or manufacturing offcuts. It is essential to distinguish this from \"second-hand\" goods that are still usable for their original purpose. If a cast iron pipe is sold for reuse as a pipe, it remains under 7303; if it is sold as scrap for melting, it falls under 720410. The classification is strictly based on the condition of the material and its intended use as raw material for the metallurgical industry.

Codes often confused with 7204.10
Common mistake. Cast iron scrap is often confused with other types of ferrous scrap. For instance, stainless steel scrap is 720421, and other alloy steel scrap is 720429. General iron or steel scrap not specifically of cast iron falls under 720449. Another common error is classifying remelted scrap ingots under 7204; however, if the scrap has been remelted into crude ingots, it may fall under 7201 (pig iron) or 7206 (iron in primary forms) depending on the carbon content and shape.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
