Import Tips
• Certify cobalt content and other alloys via spectrographic analysis to prevent disputes over high-speed qualification
• Ensure no cold-reduction; thermal processing records help prove not cold-formed status
• Avoid rust/discoloration claims at entry per chapter note; no duty allowance for surface corrosion
