U.S. imports of Chloroprene (Neoprene) Rubber (CR) in Primary Forms (SITC 23214) totaled $7.8M in August 2026, imported from 20 countries.
Importers of Chloroprene (Neoprene) Rubber (CR) in Primary Forms paid $605K in duties in August 2026, an average duty rate of 7.74% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Chloroprene (Neoprene) Rubber (CR) in Primary Forms imports of $7.8M in August 2026 ran 15% below the year-to-date monthly average of $9.2M.
Last updated: August 2026 dataChloroprene rubber, widely known in commerce as neoprene, offers a balanced combination of oil resistance, weathering resistance, and flame retardancy that distinguishes it from purely hydrocarbon elastomers. Its primary end-uses span industrial hose and belting, wet suits, adhesives, and automotive seals — applications where ozone and UV stability are non-negotiable. Production is dominated by a limited number of global manufacturers, and supply tightness in chloroprene monomer can affect lead times significantly, making inventory planning a key concern for compounders relying on CR.

Neoprene is a widely recognized trade name (originally DuPont's) for polychloroprene, and its use on commercial invoices is generally understood. However, for classification purposes, the chemical name 'chloroprene rubber (CR)' or 'polychloroprene' is preferred to avoid ambiguity, since 'neoprene' can occasionally refer to neoprene foam or fabricated articles that classify elsewhere.
Chloroprene rubber is prone to crystallization at low temperatures, which can cause bales to harden and become difficult to process upon arrival. Importers shipping CR through cold climates should specify low-crystallization grades or ensure temperature-controlled storage during transit to avoid processing delays at the compounding facility.
