HS Code for Platinum catalysts

HS code 711510 is a very specific classification for platinum catalysts that are presented in the form of wire cloth or grill. Unlike chemical catalysts that might be powders or liquids (classified in Chapter 38), these are articles of precious metal. Chapter 71 covers precious metals and articles thereof. Heading 7115 is a "basket" heading for other articles of precious metal or of metal clad with precious metal. The subheading 711510 specifically identifies catalysts made of platinum, often alloyed with rhodium, woven into a fine mesh or grill. These are used in high-temperature industrial chemical reactions, such as the oxidation of ammonia to produce nitric acid. The classification is determined by both the material (platinum) and the specific physical form (wire cloth/grill). If the catalyst were on a ceramic substrate or in a different physical form, it would likely be classified elsewhere, making the physical structure the primary determinant for 711510. This code reflects the high value of the precious metal content and the specialized industrial application of the mesh. It is critical for customs purposes to distinguish these from semi-manufactured platinum wire, as the intended use as a catalyst and the specific "cloth or grill" construction are the defining features for this subheading.

Common Misclassification

Platinum catalysts are often misclassified under HS code 3815, which covers "Reaction initiators, reaction accelerators and catalytic preparations." However, 3815 is for chemical mixtures or catalysts on a support (like platinum on carbon). When the catalyst is purely a precious metal in the form of wire cloth or grill, Chapter 71 takes precedence. Another error is using 7110, which covers platinum in unwrought or semi-manufactured forms (like simple wire), but 711510 is more specific for the finished catalyst article.

FAQ

What is the HS code for platinum catalysts?

The HS code for platinum catalysts in the form of wire cloth or grill is 711510.

Are all platinum catalysts under this code?

No, only those in the form of wire cloth or grill. Platinum catalysts on a support or in other chemical forms are classified under HS code 3815.
