Outcome
Valves were manufactured, hydrostatically tested, and export-packed at our Ahmedabad works. Air freight was arranged to Las Vegas International Airport with export customs clearance from India. The buyer handled US import customs and inland transport to Saint George under DAP terms — the standard model for US direct procurement from India.
This delivery demonstrates repeatability for US buyers sourcing Alloy 20 valves without domestic distributor markup or Chinese tariff exposure.
