Import Tips
• Verify material certification to confirm 100% steel construction, as alloy composition affects duty rates and classification
• Include detailed technical specs and pressure ratings in documentation to avoid misclassification as pressure-reducing valves
• Check for anti-dumping duties on steel valves from specific countries like China or India
