Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cold-rolled flat products
Cold reduction and annealing moves from semi-finished to specific flat-rolled heading
If hollow drill bars
If processed into hollow profiles for drilling, classifies under specialized stainless heading
If <4% chromium content"
Below stainless threshold (10.5% Cr) falls into general semi-finished iron/steel

Import Tips & Compliance
• Document titanium addition (5x C content) distinguishing from Type 304 for proper alloy classification
• Confirm no artificial oxidation or metal coating that would constitute 'further working'
