Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marketed primarily as ketone derivative
Customs may classify based on parent ketone structure if oxime function not emphasized in technical literature.
If containing >10% finishing agents
Additives with multiple paint finishing functions classified as preparations in chapter 38.
If for anti-dusting formulations
MEKO with added anti-dusting agents per chapter note (g) may be mixtures rather than pure compounds.

Import Tips & Compliance
• Include end-use statement specifying paint anti-skinning application to avoid mixture classification
• Test for water content (<0.1%) as aqueous solutions may fall under chapter 29 note (d)
• Register with TSCA for chemical import notification if annual volume >10,000 lbs
