Import Tips
• Mercerization requires fiber content declaration; treatment doesn't change heading but ensure post-process weight for nm
• Bulk cones only—no retail skeins; pitfall is partial retail packing triggering 5205 retail subheadings
• Test for excessive sizing removal per notes before nm calculation to prevent overcount errors
