Product classification
HS code for Refined copper foil: 7410.11
Copper, foil, not backed, of a thickness not exceeding 0.15mm, of refined copper.
Classification of refined copper foil under HS 7410.11
Refined copper foil is classified under HS code 7410.11. According to the Chapter 74 notes of the Harmonized System, foil is defined as a flat-rolled product of a thickness not exceeding 0.15 mm. This thickness measurement includes any surface treatment such as embossing, perforation, or coating, but excludes any backing material. Heading 7410 is specifically for copper foil, and subheading 7410.11 is reserved for foil made of refined copper (as defined in Note 1a to Chapter 74) that is not backed. This material is widely used in the electronics industry for printed circuit boards (PCBs) and in lithium-ion battery manufacturing due to its high conductivity and thin profile. The classification is strictly based on the thickness and the absence of a supporting backing like paper or plastics.

Codes often confused with 7410.11
Common mistake. The most common misclassification for refined copper foil is HS code 7409.11, which covers refined copper plates, sheets, and strip. The difference is entirely based on thickness; if the product is thicker than 0.15 mm, it must be classified under 7409. Another frequent error is using HS code 7410.21, which is for refined copper foil that is "backed" with paper, paperboard, plastics, or similar materials. If the copper foil is attached to a substrate for structural support, it moves from 7410.11 to 7410.21. Additionally, if the foil is made of a copper alloy (such as brass foil), it should be classified under 7410.12 (unbacked) or 7410.22 (backed).
Top exporters and importers of HS 741011 (the code used for refined copper foil), 2025
In 2025, the largest exporter of HS 741011 (the code used for refined copper foil) in UN Comtrade data was Taiwan, with about 29% of world exports; the largest importer in UN Comtrade data was China, with 32% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
