Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If with mechanical threading
Threaded couplings are distinctly classified outside butt weld fittings.
If seamless stainless couplings
Material and seamlessness changes to tubes/pipes chapter for couplings.
If parts for mining machinery
Specific machinery end-use supersedes general pipe fitting classification.

Import Tips & Compliance
• Include dimensional sketches showing ID <360 mm and rough forging marks
• Differentiate from mechanical couplings; emphasize weld-only design
• Monitor for 301 tariffs if from targeted countries like China
