Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in bars/rods rather than powder form
Same alloy in wrought bar form classifies under Chapter 72 stainless steel bars, not powders.
If chromium content below alloy thresholds
Non-alloy compositions fall under basic iron/steel powders per US note definitions.
If sold as pickling preparations with steel powder content
If combined with chemical preparations for surface treatment, classifies as chemical products.

Import Tips & Compliance
• Certify as 'not further worked' per chapter note to avoid higher duties; include oxygen content analysis (<0.2%) in documentation; watch for anti-dumping duties on certain stainless grades from specific countries
