While DINplus, ENplus and CANplus are all based on the European Union and ISO wood pellet standards (references grades criteria for A1, A2, and B based on EN 14961-2 or ISO 17225-2), the PFI Standards Program is the one quality scheme that currently reflects historical North American grade criteria—premium, standard and utility grades. PFI released the first version of its quality scheme in 2008. In 2010, the U.S. EPA (wood pellet association of America, also a wood pellet manufacturers association) made it known that it intended to regulate residential wood combustion appliances and the next year, PFI made substantial modifications to assure that the PFI quality scheme would comply with the EPA's anticipated requirements. The new rule is not yet finalized, but it is expected the U.S. EPA will reference the PFI quality scheme as part of its regulation.

The Pellet Fuels Institute (PFI) is a trade association representing the manufacturers of wood pellets in the United States and the companies and organizations that support them. PFI is dedicated to raising awareness about the benefits of using wood pellets to heat homes, businesses and institutions and ensuring that consistent, high-quality product is readily available in the marketplace.

Pellet Fuel Institute (PFI) in the USA has also developed standard specifications for residential and commercial grade wood pellets. The PFI wood pellet standard forms the basis of a third party accredited certification program. The certification under ENplus and CANplus are currently voluntary in Europe and Canada, while the PFI certification is mandatory in the USA.

The PFI standards has designated fuels as Premium for years, and most product sold in the US bears the PFI premium designation, which requires <1% ash content and other test requirements. However, many participants in the Pellet Fuels Institute recognize that this standard is insufficient. It does not require regular third party testing of frequent samples from production, so though one bag tested may meet the standard, the next may not. In addition, the Pellet Fuels Institute does not own the word "Premium" so if you see a fuel labeled as a "Premium" fuel, unless it actually has the PFI pellets logo on the bag, you cannot be sure that the PFI pellets manufacturer is even testing to the same standard.
