2914.13.00.00 - 4-Methylpentan-2-one (Methyl isobutyl ketone)

This classification covers 4-methylpentan-2-one, commonly known as Methyl Isobutyl Ketone (MIBK). MIBK is an organic compound that falls under the broader category of acyclic ketones without any other oxygen-containing functional groups. Its primary use is as a solvent in various industrial applications, including coatings, lacquers, and as an extraction solvent.

Distinguishing MIBK from its siblings is crucial for accurate classification. Unlike acetone (2914.11), which is the simplest acyclic ketone, or butanone (methyl ethyl ketone, 2914.12.00.00), MIBK is a more complex ketone with a branched carbon chain. The residual category, "Other" acyclic ketones without other oxygen function (2914.19.00.00), is intended for acyclic ketones not specifically enumerated elsewhere within this subheading.

As a leaf node, 4-methylpentan-2-one (Methyl Isobutyl Ketone) represents a specific chemical compound within the HTS. Therefore, there are no further subdivisions under this code. Classification within 2914.13.00.00 is determined by the precise chemical identity of the imported substance, ensuring that only MIBK is classified here, and not other, structurally different, acyclic ketones.
