Import Tips
• Verify fiber content exceeds 50% man-made fibers via lab testing to confirm classification under 6109.90; wool blends must prioritize synthetic component
• Ensure no drawstring, ribbed waistband, or tightening at bottom per heading 6109 notes to avoid reclassification to 6106
• Label as 'thermal undershirt' and provide country-of-origin documentation; common pitfall is mislabeling as outerwear leading to duties
