HS Code 2825.50 – Copper oxides and hydroxides
HS code 2825.50 is the 6-digit subheading for copper oxides and hydroxides. It is used for copper(I) oxide (cuprous oxide), copper(II) oxide (cupric oxide), copper hydroxide, copper oxide nanoparticles and red copper oxide.
What HS 2825.50 covers
Copper oxides and hydroxides are fundamental inorganic chemicals with a broad spectrum of industrial uses, including as pigments, catalysts in various chemical processes, fungicides in agriculture, and precursors in the electronics industry. Countries with strong agricultural sectors, chemical manufacturing capabilities, and electronics production, such as China, India, the United States, and Germany, are significant importers of these compounds. Exporters typically include nations with substantial chemical processing industries and access to copper resources, like Chile, Peru, and various European chemical producers. Key aspects of their trade involve their application in crop protection, their role in advanced materials science, and the impact of global copper prices on their market value. The purity and specific form, such as powder or nanoparticles, are critical for their intended high-performance applications, influencing trade specifications and pricing.

Codes often confused with 2825.50
Common mistake. Often confused with unwrought copper (7402) or other copper compounds (284290) if not specifically identified as oxides or hydroxides, which can lead to incorrect tariff classifications. Precise chemical nomenclature is crucial.
Top exporters and importers of HS code 282550, 2025
In 2025, the largest exporter of HS code 282550 in UN Comtrade data was the United States, with 37% of world exports; the largest importer in UN Comtrade data was China, with 16% of world imports. The United Kingdom reports $2.7B of its chapter 28 imports without product detail (confidential), so it may also belong among the top importers.

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).
