Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered a cast iron nipple
Very short couplings resembling nipples may shift if cast vs forged process used.
If other threaded types like tees
Threaded branches/tees of alloy use separate 7307.92.3050 codes.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Specify malleable grade (e.g
• ASTM A47); ductility tests may be requested
• Short length (<1 pipe diameter) still qualifies as sleeve, not nipple under 7307.50
