HS 271114

Liquefied Ethylene, Propylene, Butylene & Butadiene

U.S. imports of liquefied ethylene, propylene, butylene & butadiene (HS 271114) totaled $47.3M in April 2026, traded with 21 countries.

Last updated: April 2026 data

Four distinct light olefins—ethylene (2711140010), propylene (2711140020), butylene (2711140030), and butadiene (2711140040)—are grouped under this heading in their liquefied state, each serving as a critical petrochemical building block for plastics, synthetic rubber, and chemical intermediates. These commodities are key feedstocks for the polymer and specialty chemicals industries, and their import volumes reflect gaps between domestic cracker output and downstream demand. Canada leads US import supply, with South Korea and Italy also among the primary sources.

Frequently Asked Questions

Why are ethylene, propylene, butylene, and butadiene grouped together under HTS 271114 rather than classified separately?

The HS nomenclature groups these four light olefins together at the 6-digit level because they share the characteristic of being gaseous hydrocarbons transported and traded in liquefied form. The US 10-digit schedule then provides separate lines for each individual olefin, allowing precise statistical tracking while maintaining the HS structure.

Which countries are the leading suppliers of liquefied light olefins to the US?

Canada is the primary foreign source of liquefied ethylene, propylene, butylene, and butadiene imports into the US. South Korea and Italy also rank among the top suppliers, with Mexico and China rounding out the leading origins.
