Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If prepared for chemical synthesis rather than hydrocarbon cracking
Catalysts for organic synthesis may fall under 3824.90 as chemical preparations, distinct from petroleum catalysts.
If primarily alkali metal silicates without catalytic function
Base zeolite materials without active catalytic sites are inorganic silicates under Chapter 28.
If sold impregnated with petroleum oils
Oil-impregnated catalysts containing mainly petroleum oils shift to heading 2710.

Import Tips & Compliance
• Classify as hazardous material if dust form; use UN proper shipping name for catalysts
• Provide particle size and surface area specs; common issue is reclassification as mineral substances
• Ensure no asbestos content per EPA rules; bulk packaging needs proper labeling
