PACKING AND SHIPPING INFORMATION

Valve bodies and other valve components require proper protection during transportation. Packaging is selected based on product structure, weight, and machining condition. Standard export cartons are used for regular machined parts, while heavier forged or cast valve bodies and structural components are packed in fumigation-free wooden cases with anti-rust treatment and reinforcement before shipment. Supported by long-term international logistics partners, we arrange safe and controlled deliveries to customers in different regions.
