Buyer takeaway: Sodium nitrite is NaNO2 (CAS 7632-00-0) and is an oxidizer. The inquiry must identify a lawful industrial use, written specification, packing, destination and required safety/transport documents. This guide is not a food, medical or emergency-use instruction.
1. Confirm identity and legal use
Use the full name, formula and CAS number on the PO, bag and COA. Sodium nitrate, potassium nitrite, sodium sulfite and sodium metabisulfite are different chemicals. The buyer should confirm that the intended duty, import and storage are permitted before placing an order.
2. Build the specification
- NaNO2 assay and analytical method
- Nitrate, chloride, sulfate, insolubles and moisture where required
- Appearance, particle condition and caking acceptance
- Bag, liner, pallet, label and transport requirements
- Recent lot COA and current SDS
"Industrial grade" is not sufficient when impurity limits affect a metal-treatment, corrosion-control or chemical-intermediate process.
3. Treat safety as part of procurement
Public safety references identify sodium nitrite as an oxidizer. Storage, segregation, transport and handling must follow the current SDS and applicable rules. Do not rely on a webpage for emergency response. The receiving site should have approved procedures before shipment.
4. Qualify the first order
Review a recent lot COA or sample, then agree the acceptance method, packing, lot traceability and document set. Confirm who can approve a deviation and how damaged or unmatched bags will be isolated.
5. Keep regulated grades separate
An industrial product page does not prove suitability for food, feed, medical or pharmaceutical use. Those duties require the named standard, lawful status, traceability and current evidence. We do not provide curing recipes or medical dosing.
6. Compare commercial offers correctly
Normalize assay, impurities, packing, quantity, destination, Incoterm and documentation. A lower price is not comparable if the offer omits an impurity limit, transport requirement or receiving evidence.
