Import Tips
• Provide OEM part numbers and extinguisher model cross-references in commercial invoices to confirm dedicated use
• Certify stainless steel grade (typically 304/316) meets NFPA 10 standards for fire equipment corrosion resistance
• Avoid bulk shipments with generic tubing; misclassification risk high without proof of fire extinguisher specificity
