Isobutanol (2-Methyl-1-Propanol)
Isobutanol is a primary alcohol classified as a saturated monohydric butanol under HTS 2905.14.5050 due to its four-carbon chain structure and single hydroxyl group. It is a colorless liquid used as a solvent in paints, coatings, and chemical synthesis.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If mixture contains over 50% methanol by weight
Mixtures of butanols with methanol are classified under pentanol headings per chapter note on mixtures.
If sold as formulated paint solvent mixture
Blends with additives beyond simple stabilizers fall under chemical preparations rather than pure compounds.
If denatured specifically for fuel use
Denatured alcohols intended as motor fuel components shift to petroleum distillates classification.

Import Tips & Compliance
• Provide detailed chemical analysis certificates confirming C4H10O composition and purity levels above 99%
• Ensure proper UN 1212 hazardous material labeling and shipping papers for flammable liquid classification
• Verify supplier SDS includes flash point (28°C) data to avoid misclassification as a different alcohol
