Zeolite-Supported Platinum Reforming Catalyst
This supported catalyst uses platinum on a zeolite base to facilitate hydrocarbon reforming reactions in petroleum refineries. It falls under HTS 3815.19.00.00 as a supported catalyst with precious metal not specified elsewhere in subheading 3815.12 or 3815.13.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If precious metal exceeds specified weight limits
Catalysts with higher precious metal content like platinum are classified under 3815.12 based on metal weight relative to total catalyst weight.
If prepared as industrial chemical mixture without catalytic function
Loses catalytic classification if not proven as reaction initiator, falling to other chemical preparations.
If imported assembled in reactor equipment
Complete catalytic converter units are classified by apparatus function rather than catalyst component.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Verify catalyst support material (e.g
• zeolite, alumina) via lab analysis for accurate HTS classification
• Obtain supplier certifications confirming precious metal content below 3815.12 thresholds to avoid reclassification
• Include technical datasheets showing reaction initiation function to prevent misfiling under generic chemicals
