Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If intended for marine use
Marine-specific light fuel oils have separate subheadings despite similar specs.
If 90%+ distills at 210°C (light oils)
Motor spirit-like properties based on ISO 3405 distillation shift to gasoline-adjacent classifications.
If not refined to 70%+ petroleum oil purity
Crude or semi-refined oils remain under crude petroleum headings.

Import Tips & Compliance
• Provide ASTM D975 specification sheets confirming grade and sulfur limits during customs clearance
• Label containers clearly as 'Light Fuel Oil - ULSD' to prevent confusion with marine or off-road fuels
• Monitor for seasonal blending; pure distillates must not include residual components
