Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stainless steel with welded flanges
Flanged construction classifies as stainless steel pipe fittings.
If having wall thickness ≥0.107 in
Thicker walls meet criteria for separate statistical reporting within heat-resisting tubes.
If as valve/tap appliance parts
End-use in control valves shifts to Chapter 84 regulator/appliance parts.

Import Tips & Compliance
• UNS N08367 designation must match alloy chemistry certificates exactly
• Hydrostatic test reports at 1.5x design pressure validate pressure tubing intent
• Mixed alloy shipments require lot-by-lot verification to prevent commingling errors
