1. Compliance Framework

Ronghai supplies food-grade nitrous oxide exclusively. Gas sourcing, cylinder preparation, filling, inspection and packing are organised as a single food-safety chain so that the gas delivered into cream never contacts non-food-grade surfaces after cleaning.

The framework is built around three pillars: gas purity, food-contact cleanliness of the package, and pressure-equipment safety.

2. Food Regulations

• European Union: Nitrous oxide listed as food additive E942, purity criteria per EU Regulation 231/2012
• United States: Nitrous oxide GRAS, 21 CFR 184.1545
• China: Permitted processing aid / propellant under GB food additive standards
• Kosher / Halal: Certificates available per lot for branded orders
• Allergen statement: Contains no milk, gluten, nuts, soy or other declared allergens

3. Management Systems

• ISO 9001 certified quality management system
• HACCP-based food safety controls on the filling line
• FSSC 22000 implementation available for the food-grade filling scope
• Documented lot traceability from coil and gas batch to shipped carton
• Annual third-party audits and customer factory audits welcome

4. Package Safety Certificates

Refillable cylinders are produced under pressure-equipment schemes matching the destination market: TPED with Pi mark for the European Union and DOT specification for the United States. Disposable chargers are classified for UN 1070 transport and marked with lot and food-grade identification.

• TPED / Pi mark (EU cylinders)
• DOT (USA cylinders)
• UN 1070 classification for chargers and cylinders
• COA provided with every shipment

5. Shipment Document Pack

Each export order can be supplied with: commercial invoice, packing list, MSDS/SDS, certificate of origin (Form A, Form E or COO as applicable), COA per lot, ISO/HACCP certificates, TPED or DOT certificates, and a food-grade declaration letter. Request the pack when placing the order so it is checked at booking.
