HS Code 2825.70 – Molybdenum oxides and hydroxides
HS code 2825.70 is the 6-digit subheading for molybdenum oxides and hydroxides. It is used for molybdenum trioxide, molybdenum dioxide, molybdic acid, ammonium dimolybdate and ammonium heptamolybdate.
What HS 2825.70 covers
Molybdenum oxides and hydroxides are critical inorganic compounds utilized in various industrial applications, primarily as catalysts in petroleum refining and chemical production, and in the manufacturing of specialty steels and pigments. Their catalytic properties are particularly important for desulfurization processes in the oil and gas industry, addressing environmental regulations. Major importers include countries with large refining capacities and chemical manufacturing sectors, such as the United States, China, India, and European nations like Germany and the Netherlands. Exporters are typically countries with significant molybdenum mining operations and advanced processing facilities, including Chile, China, the United States, and Peru. The trade in these compounds is closely linked to global energy demands and evolving environmental regulations, which continuously drive the need for efficient and effective catalysts. Purity and specific forms are crucial for their high-performance applications.

Top exporters and importers of HS code 282570, 2025
In 2025, the largest exporter of HS code 282570 in UN Comtrade data was Chile, with 44% of world exports; the largest importer in UN Comtrade data was the United States, with 15% of world imports. Vietnam did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 11% of its exports here ($8.7M, CEPII BACI), so it may also belong among the top exporters.

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).
