Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the powder is incorporated into a lubricating preparation containing petroleum oils
Lubricating preparations containing 70% or more by weight of petroleum oils are classified under heading 3403.
If the powder is a fluoropolymer other than PTFE
Other fluoro-polymers in primary forms are classified under this subheading.
If the powder is formulated as a prepared additive for greases, not as a pure polymer
Prepared additives for lubricants are classified under heading 3824.
