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
