Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cast rather than forged
Cast fittings, even rough, are classified separately from forged ones in 7307.99.70.
If for use in pumps as parts
End-use as pump parts may reclassify under Chapter 84 pump components.

Import Tips & Compliance
• Use ISO-certified test reports for material specs; CBP often audits alloy vs. carbon steel distinctions
• Avoid any pre-shipment cleaning that could be interpreted as 'processing'; ship with mill scale intact
