3820 — Anti-freezing preparations and prepared de-icing fluids
Chapter 38: Miscellaneous chemical products
Plain-language overview
Use HS-4 3820 when importing anti-freezing preparations and prepared de-icing fluids, such as those used in vehicles or for industrial applications. These products help prevent freezing in cold weather, ensuring smooth operation in frigid conditions.
When deciding between HS-6 lines, consider the specific formulation of your product. For example, if your shipment consists of a liquid anti-freeze that contains ethylene glycol or propylene glycol, it falls under HS-6 382000. Ensure your product aligns with this classification to avoid delays.
If you're unsure whether your product qualifies as a de-icing fluid or an anti-freezing preparation, think about its intended use. De-icing fluids are typically applied to surfaces like roads and runways, while anti-freezing preparations are often used in engines or heating systems.
