Heavy Fuel Oil M-100
Heavy fuel oil M-100 is a viscous mixture of hydrocarbons derived from petroleum refining, containing less than 50% of any single hydrocarbon compound by weight. It is used primarily in industrial boilers, power plants, and large marine engines. Classified under HTS 2710.19.45 as a mixture of hydrocarbons not elsewhere specified with the specified composition limit.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains over 50% by weight of a single hydrocarbon like toluene
Products dominated by one hydrocarbon (>50%) shift to specific subheadings under 2710.19.11 for chemical purity.
If blended with biodiesel (mono-alkyl esters of fatty acids)
Biodiesel-containing preparations are excluded from 2710.19 and classified separately in 2710.20.
If contains ≥70% petroleum oils but primarily functions as a lubricant
Lubricating preparations with petroleum base move to Chapter 34 when their primary use is lubrication rather than fuel.

Import Tips & Compliance
• Obtain a Certificate of Analysis verifying hydrocarbon composition to confirm <50% single compound and ≥70% petroleum oils
• Ensure compliance with US EPA fuel quality standards and provide sulfur content documentation for customs clearance
• Avoid misclassification as crude oil (2709) by proving it is a refined product; common pitfall is inadequate flash point testing
