Import Tips
• Submit chemical analysis reports distinguishing from tool steel (chapter note e) to prevent duty reassessment
• Specify cross-section dimensions; rectangular shapes over certain sizes may trigger shape/section headings
• No duty allowance for rust per chapter note; inspect and declare condition accurately
