Overview
This HTS category, 2711.14.00.40, specifically classifies butadiene when it is in liquefied form. Butadiene is a colorless gas at room temperature and pressure, primarily produced as a byproduct of steam cracking petroleum. Its primary use is as a key monomer in the production of synthetic rubbers, such as styrene-butadiene rubber (SBR) and polybutadiene rubber (PBR), which are essential components for tires and other rubber goods. It is also used in the manufacture of plastics and resins.
This classification distinguishes butadiene from its sibling categories, which cover other liquefied gaseous hydrocarbons. Specifically, 2711.14.00.10 covers ethylene, 2711.14.00.20 covers propylene, and 2711.14.00.30 covers butylene. While all are unsaturated hydrocarbons derived from petroleum refining, butadiene is characterized by its four-carbon chain with two double bonds, differentiating it chemically and in its industrial applications from the shorter-chain olefins like ethylene, propylene, and butylene.
As a leaf node within the HTS, 2711.14.00.40 has no further subcategories. Therefore, classification under this code is definitive for liquefied butadiene. Import and export declarations for this product should ensure that the material's identity as butadiene and its physical state (liquefied) are clearly stated to align with the specific product scope of this tariff line.
