Import Tips
• Provide NACE MR0175/ISO 15156 certification if for sour service to support valuation and compliance
• Include hydrostatic test reports (min 2x operating pressure) as proof of pressure rating capability
• Avoid bundling with fittings; separate shipments prevent set classification under 7307
