Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lower API gravity variants
Heavier specific gravity oils (<25° API) separate into distinct residual fuel subheadings.
If 90%+ distills at 210°C (light oil)
Light oil preparations per ISO 3405 method exclude from heavy fuel oil categories.
If high naphthalene content (>50%)
Subheading 2707.40 specificity overrides fuel oil classification for naphthalene-dominant products.
