Denatured Mustard Seed Oil for Industrial Lubricants from China

This is refined mustard seed oil that has been denatured by adding a denaturant to make it unfit for human consumption, primarily used as a base for bio-lubricants in machinery. It falls under HTS 1514.99.50.20 because it is a fraction of mustard seed oil that is denatured but not chemically modified beyond refinement. Denaturation distinguishes it from edible oils classified elsewhere.

Import Tips

• Verify denaturation documentation from the producer, as U.S

• Customs requires proof that the oil is unfit for food use to qualify under this subheading

• Include lab analysis certificates confirming mustard seed origin and absence of chemical modification beyond denaturation

• Avoid misdeclaration as edible oil; common pitfalls include insufficient denaturant levels leading to reclassification and penalties
