Welded Steel Fence Post Pipe
A welded circular steel pipe with an outside diameter of 150 mm and wall thickness of 2.5 mm, used for constructing chain-link fence posts. It falls under HTS 7306.30.50.90 as a welded tube of nonalloy steel with specified dimensions exceeding 114.3 mm but not over 406.4 mm OD and wall 1.65 mm or more. The open-seamed or welded construction matches the 'other tubes, pipes and hollow profiles' category.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If outside diameter exceeds 406.4 mm
Larger OD pipes shift to 7306.30.10 for bigger structural tubes, changing the subheading.
If made of alloy steel
Alloy steel composition (e.g., >1.65% manganese) moves it to Chapter 73 alloy headings like 7306.50.
If seamless instead of welded
Seamless construction falls under 7304 for tubes/pipes, separate from welded profiles in 7306.

Import Tips & Compliance
• Verify wall thickness and OD measurements with calipers; customs requires certification for classification under 7306.30
• Provide mill test reports confirming nonalloy steel composition to avoid reclassification to alloy steel headings
