Although the fabric of your down jacket is knitted, the whole down jacket is not knitted, so it can't be classified as "knitted or crocheted garments and garment accessories", but should be classified as "non-knitted or crocheted garments and garment accessories" in Chapter 62, heading 62.0 1 or 62.02.
It should be noted that men and women should be divided and then classified according to the composition of the fabric.
If you are not at ease, you'd better consult your local customs, hoping to help you.
