Liquefied Butylene Gas from Mexico
Liquefied butylene (butene) is a C4 olefin gas stored under pressure as a liquid, primarily used as a feedstock in producing synthetic rubber and plastics. It falls under tariff item 2711.19.90 as an 'other' liquefied petroleum gas, not elsewhere specified, since it is not pure methane or propane and is not a separate chemically defined compound.

Import Tips

• Verify the liquefied state at import and provide a certificate of analysis to support classification
• Check if the product qualifies for a reduced duty rate under a free trade agreement
