7411.10.10 - Seamless

This HTS category, 7411.10.10, specifically covers seamless copper tubes and pipes made from refined copper. These articles are characterized by their lack of seams, achieved through manufacturing processes that create a hollow, continuous cross-section. This seamless construction is critical for applications requiring high integrity, such as in plumbing, refrigeration, and specialized industrial processes where pressure and leak resistance are paramount.

At this level of detail within the HTS, the "Seamless" designation differentiates these products from other forms of copper tubing and piping. While the sibling category, 7411.10.50.00, encompasses "Other" seamless copper tubes and pipes of refined copper (likely referring to those not specifically itemized under 7411.10.10), this node focuses on specific types that are further subdivided.

The subcategories under 7411.10.10 provide a further breakdown based on physical dimensions and presentation. 7411.10.10.30 details seamless tubes and pipes of refined copper that have a specific outside diameter range (6 mm to 16 mm) and are presented in coils on spools, indicating their use in applications where flexibility and continuous length are required. The residual category, 7411.10.10.90, covers all other seamless tubes and pipes of refined copper not meeting the specific dimensional and presentation criteria of the preceding subcategory.
