U.S. imports of liquefied ethylene, propylene, butylene & butadiene (HS 271114) totaled $31.5M in July 2026, traded with 25 countries.
Last updated: July 2026 dataFour distinct light olefins — ethylene (2711140010), propylene (2711140020), butylene (2711140030), and butadiene (2711140040) — are classified together as liquefied petroleum gases but serve as critical petrochemical building blocks rather than fuel products. Each is a primary feedstock for plastics, synthetic rubber, and chemical intermediates: ethylene for polyethylene, propylene for polypropylene, butadiene for styrene-butadiene rubber. Canada leads US import supply, with South Korea and Mexico also significant. Because these olefins are typically moved in pressurized or cryogenic tankers and require specialized receiving infrastructure, logistics constraints can be as commercially significant as tariff treatment.

Importers should verify current Section 301 applicability for shipments originating from China, as these measures have applied broadly to petroleum and chemical products from that origin. South Korea and Canada, the leading suppliers, are not currently subject to Section 301 tariffs on these products, but trade-remedy exposure can change; consulting a licensed customs broker or trade attorney before entry is recommended.
These materials are classified as flammable gases under DOT hazardous materials regulations (49 CFR Parts 171–180) and require proper shipping names, UN numbers, and hazard labels on transport documents. Safety Data Sheets (SDS) must accompany shipments, and receiving terminals must be equipped for cryogenic or pressurized LPG handling. CBP entry documentation should reflect the correct chemical identity to align with both the HTS classification and the hazmat shipping description.
