Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the paste is considered a chemical product not specifically based on graphite
Heading 38.24 covers chemical products and preparations of the chemical or allied industries, which could apply if the graphite content is not the essential character.
If the paste contains precious metal compounds
Section note 1(B) requires classification in heading 28.43 for goods answering to that description, overriding other headings.
