Independent R&D for the NSF H1 lubricant basket the modern Indian food and beverage plant actually needs — NSF H1 aluminium-complex and polyurea grease on USP white-oil base, NSF H1 hydraulic oil for packaging machinery, NSF H1 gear oil for mixers and decanters, NSF H1 chain oil for conveyor and oven chain, NSF H3 edible release oil for hooks and trolleys, and the cleanroom silicone lubricant for sterile-zone equipment. Built around the FDA 21 CFR 178.3570 ingredient whitelist, NSF International H1 registration discipline, and the ISO 21469 hygienic-manufacturing framework that Britannia, Mondelez, Amul, Parle, Hindustan Unilever, Nestle, Coca-Cola and PepsiCo bottlers are increasingly enforcing across their supply chains.
The ingredient whitelist is absolute. An NSF H1 lubricant can contain only ingredients listed in FDA 21 CFR 178.3570 and registered with NSF International. There is no equivalent ingredient or "good enough" substitution. The USP white mineral oil must carry an NSF-listed manufacturer reference. The thickener must be NSF-listed. The antioxidant, the rust inhibitor, the anti-wear, the copper passivator, the anti-foam — every single one must come from the NSF-listed component list. This is the fundamental difference between food-grade and industrial-grade formulation and it eliminates roughly 95% of the additive catalogue.
USP white oil sets the base-oil chemistry. Standard mineral lubricant base oils (Group I and II) contain measurable polycyclic aromatic hydrocarbon (PAH) content from the original crude. Food-contact requires PAH below 5 mg/kg under USP/FDA. The only mineral base that meets this is USP-grade white mineral oil — produced by additional hydroprocessing to saturate every aromatic. PAO synthetic and food-grade polyol ester are the synthetic alternatives. We blend USP white oil with PAO and ester to engineer viscosity index, low-temperature behaviour and polarity.
The wash-down environment is hot, wet and chemical. A dairy line does CIP (Clean-in-Place) every shift with 80C caustic solution. A beverage filler is washed with peracetic acid. A meat processing line is hosed down with chlorinated water. Every grease and oil in the plant must resist water washout (ASTM D1264), survive caustic exposure without breaking down, and maintain corrosion protection on stainless-steel and food-grade alloy components. Polyurea and aluminium-complex thickeners are dominant because they resist this environment far better than simple lithium.
OEM lubrication is now a procurement requirement at major brands. Mondelez (Cadbury, Oreo, 5Star), Britannia, Parle, Nestle India, Hindustan Unilever, Amul, Mother Dairy, Coca-Cola India, PepsiCo India and the major QSR back-of-house operations — almost every major branded food manufacturer now requires NSF H1 on every lubrication point above the food line. Many have additionally added ISO 21469 facility certification to their supplier requirements. We design our H1 range to be acceptable to these procurement standards. See our NSF H1 food-grade grease guide.

NSF H1 is the registration category from NSF International for lubricants used in food processing equipment where there is potential for incidental food contact — for example, a drop of grease falling from an overhead bearing onto a conveyor below. Only ingredients listed in FDA 21 CFR 178.3570 and individually registered with NSF can be used in an H1 product.
NSF H1 is no longer optional — every major branded food manufacturer in India (Britannia, Mondelez, Nestle India, Hindustan Unilever, Amul, Parle, ITC, Coca-Cola, PepsiCo) now requires H1 lubrication on all above-line machinery as a condition of food safety compliance, typically tied to their FSSC 22000 or BRC certification.
H1 is for incidental food contact — the dominant category, covering bearings, gearboxes, chains and hydraulics above the food line.
H2 is for no-contact applications, below the food line, where contact is structurally impossible. H2 has fewer ingredient restrictions but cannot be used anywhere above the food line.
H3 (and 3H) is for direct food contact — release oils applied to hooks, trolleys, conveyor wheels and pans. H3 is typically edible-grade soluble vegetable oil. There is also a 3H category for release on grills and trolleys with direct contact.
No. NSF H1 is a product-level registration of the lubricant formulation — it certifies that the ingredients are food-contact-safe. ISO 21469 is a hygiene-management system covering the manufacturing facility itself — raw-material storage, blending process hygiene, packaging cleanliness, batch traceability and contamination control.
Many major food manufacturers now ask for both: the lubricant must be NSF H1 registered AND the lubricant blender must hold ISO 21469 certification for the facility. We advise clients on aligning their plant to ISO 21469 requirements as part of plant setup.
