Methyl Ethyl Ketoxime (MEKO) from Japan
Methyl ethyl ketoxime, a derivative of hydroxylamine, is a clear, low-viscosity liquid used primarily as an anti-skinning agent in alkyd resin paints and coatings to prevent surface film formation during drying. It functions by complexing with metal driers, delaying oxidative drying. This chemically defined organic compound falls under HTS 2928.00.10.00 as a specific hydroxylamine derivative.

Import Tips
• Verify purity ≥99% with certificate of analysis (COA) as impurities may affect classification under chapter 29 note (a)
• Include safety data sheet (SDS) showing anti-skinning agent use to distinguish from general solvents (chapter 27 exclusions)
• Ensure packaging complies with DOT/UN 1993 flammable liquid regulations for transport
