Acrylonitrile is classified as a flammable liquid and toxic substance under DOT hazmat regulations (49 CFR). Shipments require proper UN number marking, hazard labeling, and emergency response information. Ocean carriers and port terminals impose specific stowage and segregation requirements; importers should confirm compliance with their freight forwarder before booking.

Because acrylonitrile is consumed in large volumes by resin and fiber producers operating on tight inventory cycles, import timing is closely tied to downstream production schedules. Supply disruptions at major producing facilities — or shifts in propylene feedstock availability — can cause rapid price and availability swings, making forward contracting and diversified sourcing strategies important risk-management tools.
