2905.14.10.00 - tert-Butyl alcohol, having a purity of less than 99 percent by weight 🖩

This classification covers tert-Butyl alcohol (also known as 2-methylpropan-2-ol) specifically when its purity is less than 99 percent by weight. This means the material contains a significant amount of impurities or is a mixture where tert-Butyl alcohol is the primary component but not highly refined. Such products are often used as solvents or as intermediates in chemical synthesis.

This category is distinguished from its sibling category, 2905.14.50, which covers "Other" butanols not otherwise specified. While both fall under "Other butanols," this specific subcategory is defined by the purity criteria of tert-Butyl alcohol, implying that 2905.14.50 would cover other forms of tert-Butyl alcohol (e.g., greater than 99% purity) or other isomers of butanol not explicitly mentioned elsewhere.

As this is a leaf node, there are no further subdivisions. Therefore, the classification hinges entirely on the identification of tert-Butyl alcohol and its purity level falling below the 99 percent threshold. Importers and exporters should ensure their documentation accurately reflects the purity of the tert-Butyl alcohol to ensure correct classification and avoid potential delays or penalties.
