Products classified under HTS 2711.14.00.40
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.
Industrial Liquefied Butadiene-1,3
Liquefied 1,3-butadiene for industrial chemical synthesis, meeting specifications for latex and elastomer production. HTS 2711.14.00.40 applies to this liquefied form of butadiene as a petroleum gas.
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.
