For US export statistics, individual NGL fractions such as ethane, propane, and butane are aggregated under the Natural Gas Liquids end-use category. However, for Electronic Export Information filing purposes, each fraction is reported under its specific Schedule B commodity code, which matters for accurate trade data and any applicable export controls.

NGL exports generally require a Shipper's Export Declaration (filed as EEI in AES), a bill of lading, a certificate of quality or product specification sheet, and compliance with DOT hazardous materials transport regulations. Cryogenic or pressurized shipments also require vessel compatibility documentation and may be subject to port-specific handling requirements.
