Its first two digits, 74, are the chapter; the next two, 03, number the heading within it. Its subheadings add two more digits (7403.11, 7403.12, 7403.13). ## In other countries No national tariff lines under heading 74.03 are live on border.bot yet. Tariffs built on the Harmonized System use its subheadings at six digits and add their own digits after them. - Previous heading: [74.02](https://staging.border.bot/hs-codes/7402) Unrefined copper; copper anodes for electrolytic refining - Next heading: [74.04](https://staging.border.bot/hs-codes/7404) Copper waste and scrap ## Frequently asked questions ### What does HS heading 74.03 cover?
