As we all know, this "pre-approval process" is the industry standard for determining food grade lubricants. The USDA/FSIS “List of All Substances and Non-Food Compounds” is the “bible/authoritative” for food grade lubricants involved in food and beverage processors around the world. The inventory lists all lubricants under the labels H-1, H-2, H-3 and P-1.
USDA H-1 lubricants are true food-grade lubricants approved by the United States Department of Agriculture. The composition is permitted for the lubrication of equipment parts that may come into contact with food.
USDA Class H-2 lubricants, which generally contain non-toxic ingredients/ingredients, are used to lubricate equipment in food processing plants. There is no possibility of food contact with lubricating oil or lubricated machine parts.
USDA H-3 lubricants refer to water-soluble oils. Machine parts must be washed and emulsion removed before use again.
USDA P-1 oils refer to lubricants that comply with the conditions set forth in the USDA authorization letter. This type of lubricant should not be used in food and beverage processing plants.
