What decides the code
A baby onesie is a knitted garment for babies, classified in heading 6111 by fiber content. Cotton onesies fall under 6111.20.60.70 and polyester onesies under 6111.30.50.70.
- Fiber content decides the subheading. Cotton leads to 6111.20.60.70. Synthetic fibers such as polyester lead to 6111.30.50.70.
- Knitted or crocheted construction places the garment in heading 6111. A woven baby garment is classified elsewhere.
- The garment is sized and labeled for babies, which keeps it in heading 6111 rather than in children's apparel headings.
Common mistakes
- Classifying a cotton onesie in 6111.30.50.70 is wrong because that line covers synthetic fibers, not cotton.
- Classifying a baby onesie in heading 6110 is wrong because heading 6110 covers sweaters and similar knit garments, not babies' garments.
- Classifying a knitted baby onesie in heading 6209 is wrong because heading 6209 covers babies' garments that are not knitted or crocheted.
