Import Tips
• Certify minimum yield strength if claiming high-strength steel status (note a), though not required for this heading
• Document hot-rolling process; extruded bars allowed but must declare production method accurately
• Separate from tool steel grades; misdeclaration as tool steel (note e) leads to 7228.10 higher duties
