In HS code, flat knitting machine clothing (i.e. sweaters) should be classified into the eleventh category, chapter 6 1, which is called knitted fabric and crocheted fabric.

The main classification basis of HS coding is the weaving mode, structure and characteristics of goods, not whether they are woven or not. Although the flat knitting machine is a machine that uses the needle bed of the flat knitting machine to knit, its fabric is made up of a large number of knitting loops, but it is different from the general woven fabric, and it belongs to the category of knitted fabric or crochet.
