More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is a complete water filter cartridge with housing
Complete filtering apparatus for liquids is classified in Chapter 84.
If the product contains significant amounts of other activated minerals
Mixtures of activated carbon with other activated minerals may be classified elsewhere.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Clearly describe the product as activated carbon in block form, not as a complete filter cartridge
• If the blocks are encased in plastic or other materials, the complete filter may be classified differently
• Provide density and pore structure specifications to support classification
