Platinum Supported Alumina Catalyst
A high-performance catalyst consisting of platinum dispersed on an alumina support, used primarily in petroleum refining for catalytic reforming processes. It falls under HTS 3815.12.00.90 as a supported catalyst with precious metal (platinum) as the active substance, not specified elsewhere. This classification applies to its role as a reaction accelerator in hydrocarbon processing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If precious metal content is explicitly 2% or less by weight
Subheading 3815.11 covers supported catalysts with precious metals at or below 2% concentration, shifting from the 'other' category.
If not supported on a base but presented as powder or granules
Unsupported catalyst preparations fall under 3815.90, as support is a key criterion for 3815.12.
If imported as pure platinum salts or compounds without carrier
Pure precious metal compounds without catalytic preparation or support are classified in Chapter 28 as metal salts.

Import Tips & Compliance
• Obtain detailed chemical composition certificates to verify precious metal content; ensure EPA pre-notification for hazardous material shipment; avoid misclassification by confirming support material is inert like alumina
