Import Tips
• Submit chemical analysis reports confirming alloy elements like chromium/molybdenum per chapter note (e)
• Declare exact hot-rolled status; any polishing or coating constitutes 'further worked' requiring different code
• Measure and document maximum cross-sectional dimension to prevent misclassification to larger size subheading
