Product classification
HS code for Platinum catalyst mesh: 7115.10
Metal, catalysts in the form of wire cloth or grill, of platinum.
Classification of platinum catalyst mesh under HS 7115.10
Platinum catalyst mesh is classified under HS code 7115.10 because it represents a finished article made of precious metal specifically designed for industrial catalytic purposes in the form of a wire cloth or grill. Chapter 71 of the Harmonized System governs natural or cultured pearls, precious or semi-precious stones, and precious metals. Within this chapter, heading 7115 is reserved for \"Other articles of precious metal or of metal clad with precious metal.\" Subheading 7115.10 is highly specific, covering catalysts in the form of wire cloth or grill, of platinum. This classification is determined by the material composition (platinum) and the physical form (mesh or grill) intended for a specific industrial function, such as ammonia oxidation or hydrogen cyanide production. The General Rules of Interpretation (GRI) 1 and 6 are applied here, as the terms of the heading and subheading provide a precise description of the product. Unlike bulk platinum or chemical compounds, this item is a manufactured article of wire designed for chemical reactions.

Codes often confused with 7115.10
Common mistake. Platinum catalyst mesh is frequently confused with supported catalysts under HS code 3815.12. However, heading 3815 is for catalysts consisting of precious metal deposited on a support (like ceramic or silica), whereas 7115.10 is for catalysts made entirely of precious metal wire. Another common error is using 7110.11, which is for unwrought platinum; this is incorrect because the mesh is a manufactured article, not a raw material.
Top exporters and importers of HS 711510 (the code used for platinum catalyst mesh), 2025
In 2025, the largest exporter of HS 711510 (the code used for platinum catalyst mesh) in UN Comtrade data was Germany, with 48% of world exports; the largest importer in UN Comtrade data was Germany, with 29% 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).
