Last updated: July 2026 dataEthylene glycol– and propylene glycol–based antifreeze and deicing formulations serve the automotive coolant, aviation ground-support, and infrastructure maintenance markets, making this a widely traded industrial chemical heading. Canada dominates US import supply, a position reinforced by USMCA preferential treatment that benefits Canadian-origin shipments. Belgium and Germany are also significant sources, reflecting European specialty chemical production capacity. The single 10-digit line 3820000000 covers the entire heading, so classification disputes typically center on whether a product is a prepared formulation versus a pure chemical compound classified elsewhere.

Heading 3820 covers formulated mixtures — products that combine a freezing-point depressant (such as ethylene or propylene glycol) with corrosion inhibitors, dyes, or other additives to make a ready-to-use or concentrate product. Pure, undiluted glycols without such additives are generally classified in chapter 29 as organic chemicals. Importers should obtain full ingredient breakdowns from suppliers to support the correct heading determination.
Generally yes — both automotive engine coolants and aircraft ground-deicing fluids that meet the 'prepared formulation' criterion fall under heading 3820. However, certain specialized runway or aircraft deicing products may carry additional regulatory documentation requirements from the FAA or airport authorities, separate from customs classification.
