Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If austenitic but hot-worked
Non-cold-formed high alloy stainless tubes use different subheadings.
If imported in screw machine lengths
Precision lengths ≤3m for machining classify as Chapter 73 blanks.
If for mining machinery parts
Wear part tubing for specific machinery goes to Chapter 84/85.

Import Tips & Compliance
• Specify high manganese (7.5-9%) and silicon (3.5-4.5%) content unique to Nitronic 60
• Provide hardness test results (Rockwell) demonstrating superior galling resistance
• Document as 'tubing' not 'pipe'; NPS sizing can trigger 7304 pipe classification
