Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily butylene content with minor butadiene
Butylene takes precedence over butadiene in mixed C4 streams for classification purposes within liquefied gases.
If when imported pre-polymerized as synthetic rubber
Polymerized butadiene products like polybutadiene rubber fall under Chapter 39 plastics rather than raw gaseous feedstocks.

Liquefied 1,3-Butadiene
Pure liquefied 1,3-butadiene (C4H6), a gaseous hydrocarbon liquefied under pressure for storage and transport. It falls under HTS 2711.14.00.40 as butadiene within the category of liquefied petroleum gases and other gaseous hydrocarbons, specifically the butadiene subheading.
Polymer-Grade Liquefied Butadiene
High-purity liquefied butadiene (>99.5%) specifically refined for polymerization in rubber and plastics production. Classified under HTS 2711.14.00.40 due to its liquefied gaseous hydrocarbon form and butadiene composition.
Refrigerated Liquefied Butadiene Cargo
Bulk liquefied butadiene transported in refrigerated ISO tanks at -4°C to prevent polymerization. Falls under HTS 2711.14.00.40 as specifically identified butadiene among liquefied gaseous hydrocarbons.
Stabilized Liquefied Butadiene
Liquefied butadiene with polymerization inhibitors (TBPE/PPP) to maintain stability during storage and shipping. Classified under HTS 2711.14.00.40 as butadiene despite minor stabilizers, as they don't change principal character.
