Chapter 72: Iron and steel
Plain-language overview
Use HS-6 721631 when importing or exporting hot-rolled U sections made of iron or non-alloy steel that are 80mm or taller. For example, a shipment of U-shaped steel beams used in construction would fall under this code.
This code specifically covers U sections that are hot-rolled, hot-drawn, or extruded, distinguishing them from other shapes like angles or flat bars found in HS-6 721630. If your product is a different shape or has a height less than 80mm, you’ll need to look at other classifications.
When dealing with U sections, it’s crucial to note the height requirement. Products under this code must meet or exceed 80mm in height, while smaller U sections would be classified differently, possibly under HS-6 721632.
Understanding the specifics of 721631 helps ensure compliance with customs regulations and avoids misclassification. Accurate descriptions on invoices and shipping documents are essential for smooth clearance.
