Isopentane (Natural Gas Derived) from Canada
Isopentane, a branched saturated acyclic hydrocarbon (2-methylbutane), is extracted from natural gas liquids via fractionation. Classified under HTS 2901.10.40.00 due to its natural gas origin and status as a C5 saturated hydrocarbon beyond butanes. Commonly used in expanding polystyrene foam production.

Import Tips
• Include gas processing plant certificates proving natural gas derivation to prevent Chapter 27 misclassification
• Comply with DOT hazardous material shipping (UN 1265); check for anti-static drum requirements
• Test for isomer purity; mixtures with n-pentane >20% may require average classification
