Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If with higher base metal content
Supported catalysts with specified base metal weight percentages shift to 3815.11.
If marketed as hydrocarbon processing additive
Chemical preparations for specific industries may classify under 3824 rather than pure catalysts.
If primarily carbide compound
Carbide-based preparations fall under Chapter 28 inorganic chemicals.

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
• Provide BET surface area analysis confirming high-support characteristics essential for 3815 classification
• Declare nickel loading percentage accurately; excessive metal may trigger 3815.11 base metal heading
• Include reaction test data demonstrating methanation activity to distinguish from mere chemical compounds
