United States
SDS must follow OSHA HazCom 29 CFR 1910.1200.
Listed in EPA TSCA Inventory.
European Union
REACH compliant SDS mandatory (EU 2020/878).
Classified under CLP Regulation (EC) No 1272/2008.
Food-Grade Sodium Nitrate SDS Notes
Food additive code: INS 251 / E251
Extra purity requirements:
Low heavy metals (Pb, As, Cd).
Microbial limits.
Non-GMO source for some markets.
Allergens typically “None”.
Food-grade SDS must still follow the same 16-section GHS format, but with:
Typical specification ranges used for food-grade sodium nitrate (example, industry practice)
These are recommended example limits commonly requested by food manufacturers and suppliers. Verify legally binding limits for your jurisdiction.
Lead (Pb): 0.1 – 2.0 mg/kg (many food-grade specs target ≤0.5 mg/kg or ≤1 mg/kg; stricter customers may require ≤0.1–0.2 mg/kg)
Arsenic (As): 0.05 – 1.0 mg/kg (common commercial specs ~≤0.1–0.3 mg/kg)
Cadmium (Cd): 0.01 – 1.0 mg/kg (many aim for ≤0.05–0.1 mg/kg)
Mercury (Hg): 0.01 – 0.1 mg/kg (often ≤0.01–0.02 mg/kg for stricter specs)
Total heavy metals (as Pb): 1 – 10 mg/kg (used by some pharmacopeial or commercial specs as a catch-all; lower is safer)
Food safety sections added (e.g., acceptable daily intake, regulatory limits).
Practical procurement / compliance tips
If your product is sold as a food additive (INS 251 / E251 / E251), check FSSAI (India) or EU/Codex rules for additive purity and maximum contaminant limits. Some jurisdictions require declarative limits or reference to pharmacopoeial monographs.
For export, match the strictest customer/regulatory requirement (e.g., EU importers commonly expect tighter limits than some domestic markets).
Ask suppliers for food-grade certificate, CoA, and ISO 17025 lab reports for heavy metals.
Want me to do next?
I can:
Create a food-grade sodium nitrate specification sheet (table) with recommended, strict, and minimum acceptance limits (editable Word/PDF) for procurement or QC.
Draft a sampling & testing SOP and a CoA template including fields for method, LOD/LOQ, and lab accreditation.
Help you identify the exact legal limits for a specific market (FSSAI / EU / Codex / FDA) — I’ll need to browse for that; tell me which regulator/country you want and I’ll look up the current limits (I can do that if you want me to fetch official numbers).
Which would you like me to prepare right now?

Eye irritation — Category 2A
May cause fire or intensify fire due to oxidizing properties
GHS Label Elements
Pictograms:
(Flame over circle – Oxidizer)
(Exclamation mark – Irritant)
Signal word: Warning
Hazard statements:
H272: May intensify fire; oxidizer.
H319: Causes serious eye irritation.
Precautionary statements:
Keep away from heat, combustible materials.
Wear protective gloves, goggles.
Wash hands thoroughly after handling.
Heavy metals to test (minimum)
Lead (Pb)
Arsenic (As)
Cadmium (Cd)

(optional) Total heavy metals expressed as Pb (sometimes used as a quick acceptance criterion)
(optional) Other metals of concern for your supply chain: chromium (Cr), nickel (Ni), copper (Cu), zinc (Zn)
INDIA — FSSAI (Food Safety & Standards Authority of India)
Regulation: Food Safety and Standards (Food Product Standards & Food Additives) Regulations, 2011
✔ Additive Category: Preservative
✔ INS Number: 251
✔ Permitted Foods:
Cured meats and processed meat products (strictly limited)
Not allowed in general foods unless listed in the additive tables.
✔ Maximum Usage Level:
Typically up to 500 mg/kg in cured meats (combined nitrate + nitrite), BUT varies based on food category.
