3814.00.50.10 - Containing methyl chloroform (1,1,1-trichloro- ethane) or carbon tetrachloride

This HTS subcategory, 3814.00.50.10, specifically covers organic composite solvents and thinners that are not elsewhere specified or included, and which contain either methyl chloroform (also known as 1,1,1-trichloroethane) or carbon tetrachloride. These substances are typically used as cleaning agents, degreasers, or as components in paint and varnish removers. The defining characteristic for classification under this heading is the presence of these specific chlorinated hydrocarbons as significant ingredients.

Distinguishing this category from its sibling, 3814.00.50.90 ("Other"), is crucial for accurate classification. While both fall under "Other" organic composite solvents and thinners not elsewhere specified, 3814.00.50.10 is exclusively for those formulations explicitly containing methyl chloroform or carbon tetrachloride. Any other composite solvent or thinner, even if used for similar purposes or having a similar formulation but lacking these specific ingredients, would be classified under the residual category 3814.00.50.90.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification relies solely on identifying the presence or absence of methyl chloroform or carbon tetrachloride within the organic composite solvent or thinner. Importers and exporters should carefully review the composition of their products to ensure they are correctly assigned to this specific subcategory based on these key chemical components.
