HS Code for Methyl isobutyl ketone

Methyl isobutyl ketone (MIBK), chemically known as 4-methylpentan-2-one, is classified under HS code 2914.13. This classification is situated within Chapter 29 (Organic Chemicals) and heading 2914 (Ketones and quinones). Subheading 2914.13 is specifically assigned to 4-methylpentan-2-one. MIBK is an acyclic ketone that does not contain other oxygen functions. It is primarily produced from acetone and is valued for its ability to dissolve resins, oils, and nitrocellulose. The classification is determined by its chemical structure as a saturated acyclic monoketone. For customs purposes, the product must be a separate chemically defined compound; if it is mixed with other solvents to create a proprietary blend, the classification would shift to Chapter 38.

Products Included

• Pure methyl isobutyl ketone (MIBK)
• 4-methylpentan-2-one
• Isopropylacetone
• MIBK used as an extraction agent in mineral processing
• Technical grade methyl isobutyl ketone

Common Misclassification

MIBK is frequently misclassified under HS code 2914.11 (acetone) or 2914.12 (butanone) due to their similar industrial uses as solvents. It may also be confused with mesityl oxide (2914.19), which is an unsaturated acyclic ketone. Furthermore, if MIBK is imported as a component of a prepared solvent mixture, it should be classified under 3814.00.
