HS Code for Butyl carbitol

Butyl carbitol, known chemically as diethylene glycol monobutyl ether, is classified under HS code 2909.43. This classification is based on its identity as an ether-alcohol. Heading 2909 covers ethers, ether-alcohols, and their derivatives. The subheading 2909.43 is specifically designated for the monobutyl ethers of ethylene glycol or diethylene glycol. As a separate chemically defined organic compound, it falls under Chapter 29. The molecule contains both an ether functional group and a hydroxyl (alcohol) group, which defines its placement within the ether-alcohol sub-category. This chemical is a clear, high-boiling liquid used extensively as a solvent in the paint and printing ink industries. The HS system requires precise chemical nomenclature for these substances to ensure they are not confused with simpler alcohols or complex mixtures.

Common Misclassification

Butyl carbitol is frequently confused with HS code 2909.41 (2,2'-Oxydiethanol) or 2909.44 (Other monoalkylethers of ethylene glycol). The distinction is based on the specific alkyl group attached to the glycol; 2909.43 is strictly for the monobutyl version. Furthermore, if the product is sold as a prepared mixture of various solvents rather than a pure chemical, it may be misclassified here instead of under HS code 3814.00, which covers organic composite solvents and thinners.

FAQ

What is the HS code for Butyl Carbitol?

The HS code for Butyl Carbitol (diethylene glycol monobutyl ether) is 2909.43.

Is Butyl Carbitol classified as a simple alcohol?
