“Food-grade grease” is one of the most requested – and most misunderstood – product categories we export. This post clarifies what NSF H1 actually means, where it is legally required, and what documentation you should demand from any supplier.<\/p>\n

What NSF H1 actually certifies<\/h2>\n

NSF (National Sanitation Foundation, USA) administers the registration program originally defined by the USDA. An H1 registration means: this lubricant is composed of substances acceptable for incidental food contact<\/em> – components evaluated against FDA 21 CFR 178.3570 and related listings. It does not<\/strong> mean the lubricant is edible, and it does not mean any amount is acceptable. “Incidental contact” is defined as technically unavoidable traces – a leaking bearing over a conveyor, grease migration at a chain.<\/p>\n

Where H1 is required<\/h2>\n
    \n
  • Any lubricated position where leakage could drip, mist or migrate into food, packaging, or food-contact surfaces: conveyor bearings above product lines, chains and oven chains, gearbox output shafts near open product, filling machine slides.<\/li>\n
  • Export goods to the USA, EU, Canada, Australia, Japan: H1 (or local equivalent, e.g. ISO 21469 certification) is either legally required or demanded by retailer audit standards (BRCGS, SQF, FSSC 22000).<\/li>\n<\/ul>\n

    Where H2 is fine:<\/strong> positions with zero possibility of food contact – the compressor in a separate machine room, forklift chassis, the outside of sealed equipment. H2 greases are cheaper and perform better in extreme loads. Over-specifying H1 everywhere wastes money.<\/p>\n

    The paperwork that backs the claim<\/h2>\n

    Any genuine H1 product has three things you can verify:<\/p>\n

      \n
    1. An NSF registration number<\/strong> – check it live at nsf.com (search “NSF White Book” – registrations are public and free to verify).<\/li>\n
    2. A COA per batch<\/strong> matching the registered formulation.<\/li>\n
    3. ISO 21469 certification<\/strong> (optional but stronger) – adds hygiene manufacturing requirements, not just formulation review.<\/li>\n<\/ol>\n

      Buying “food-grade” grease without a verifiable NSF number is buying a label. We have seen quote sheets where the “H1” line item has no registration behind it at all.<\/p>\n

      Our H1 line<\/h2>\n

      LLF Grease manufactures NSF-registered H1 greases in both aluminium-complex and calcium-sulfonate chemistries, NLGI 1 and 2, suitable for bakery ovens (up to 200 °C), bottling lines (water washdown), and general food-plant bearings. Registration numbers are printed on the COA and available for your audit file before you order.<\/p>\n
