Import Tips
• Declare intended structural use but classify based on form, not application, to prevent shifts to line pipe subheadings
• Anti-dumping duties may apply; check Commerce scope rulings for Chinese-origin hollow sections
• Bundle in sets only if sold as such; individual pipes classify separately from assembled structures
