Product classification
HS code for Copper chloride oxide: 2827.41
Chloride oxides and chloride hydroxides, of copper.
Classification of copper chloride oxide under HS 2827.41
Copper chloride oxide, also known as copper oxychloride, is classified under HS code 2827.41. This classification falls within Chapter 28, which covers inorganic chemicals and precious metal compounds. Specifically, heading 2827 covers chlorides, chloride oxides, and chloride hydroxides. The classification is determined by the chemical composition of the substance; as a compound consisting of copper, chlorine, and oxygen (or hydroxyl groups), it fits the definition of a chloride oxide. This product is distinct from simple copper chlorides because of the presence of the oxide or hydroxide component. It is widely used in industrial applications and as a precursor in the chemical industry, though its most common commercial application is as a fungicide in agriculture.

Codes often confused with 2827.41
Common mistake. Copper chloride oxide is often misclassified under 2827.39, which is the general category for "other chlorides." However, because it is specifically a chloride oxide, 2827.41 takes precedence. Another frequent error is classifying the product under 3808.92 as a fungicide. While it is used as a fungicide, Chapter 28 takes priority for separate chemically defined compounds unless they are put up in forms or packings for retail sale as disinfectants or similar products.
Top exporters and importers of HS 282741 (the code used for copper chloride oxide), 2025
In 2025, the largest exporter of HS 282741 (the code used for copper chloride oxide) in UN Comtrade data was India, with 29% of world exports; the largest importer in UN Comtrade data was the United States, with 21% 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 that did not report are estimated from what other countries recorded trading with them. 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).
