3820.00.00.00 - Antifreezing preparations and prepared deicing fluids 🖩

This HTS classification, 3820.00.00.00, encompasses a range of specialized chemical preparations designed to prevent freezing or to remove ice and frost. These include, but are not limited to, antifreeze solutions typically added to engine cooling systems, and deicing fluids used on aircraft, roadways, and other surfaces. The primary function of these products is to lower the freezing point of liquids or to melt existing ice.

As a classification within Chapter 38 (Miscellaneous chemical products), this heading stands apart from classifications of raw chemical elements, simple compounds, or finished goods in other sections of the HTS. For instance, it is distinct from the classification of pure ethylene glycol (which would fall under Chapter 29), or finished automotive parts that might contain antifreeze as a component. Its focus is specifically on the *prepared preparations* for their stated anti-freezing or deicing purposes.

Since 3820.00.00.00 is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification under this heading relies solely on identifying products whose primary characteristic and intended use align with the description of antifreezing preparations and prepared deicing fluids. Key determinative factors include the product's formulation, its stated function on packaging, and its typical application.
