Product classification
HS code for Copper foil: 7410.11
Copper, foil, not backed, of a thickness not exceeding 0.15mm, of refined copper.
Classification of copper foil under HS 7410.11
Copper foil is classified under HS code 7410.11 when it consists of refined copper that is not backed by any other material and does not exceed a thickness of 0.15 mm. The classification logic for Chapter 74 dictates that copper products are categorized by their shape and dimensions. Heading 7410 specifically addresses foil, which is defined as a flat-rolled product of a thickness not exceeding 0.15 mm (excluding any backing). The subheading 7410.11 is reserved for refined copper, which must contain at least 99.85% copper by weight or meet specific impurity limits defined in the Chapter 74 legal notes. This classification applies to foil produced through rolling or electro-deposition, provided it remains in its raw, unbacked state. The thickness measurement is critical; if the product exceeds 0.15 mm, it is reclassified as sheet or strip under heading 7409.

Codes often confused with 7410.11
Common mistake. The most frequent misclassification occurs between 7410.11 (unbacked) and 7410.21 (backed). If the copper foil is reinforced with paper, plastics, or similar materials, it must be moved to 7410.21. Additionally, importers often confuse foil with copper strip (7409). The definitive boundary is the thickness of 0.15 mm; any flat-rolled product thicker than this, even by a fraction of a millimeter, falls under 7409. Finally, if the foil is made of a copper alloy (such as brass or bronze) rather than refined copper, it should be classified under 7410.12 (unbacked) or 7410.22 (backed).
Top exporters and importers of HS 741011 (the code used for copper foil), 2025
In 2025, the largest exporter of HS 741011 (the code used for 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).

Questions about copper foil
What is the HS code for Copper foil?
The HS code for Copper foil is 741011 (Copper; foil, not backed, of a thickness not exceeding 0.15mm, of refined copper). Refined copper foil that is not backed and has a thickness not exceeding 0.15 mm is classified under HS code 7410.11.
How do I classify Copper foil for customs?
Copper foil is classified under HS code 741011 — Copper; foil, not backed, of a thickness not exceeding 0.15mm, of refined copper. This is a 6-digit subheading level code.
Does the 0.15 mm thickness limit include the backing?
No, according to the HS Chapter 74 notes, the 0.15 mm thickness limit for classification as foil is calculated by measuring the copper layer only, excluding any backing material like paper or plastic.
Which countries are the top exporters of copper foil (HS 741011)?
