Yes—the US schedule provides distinct 10-digit lines for corduroy (6204522010 for women's, 6204522020 for girls') and blue denim (6204522030 for women's, 6204522040 for girls') constructions. The separation matters because these fabric types are tracked separately for textile statistical purposes and, in some trade remedy contexts, have been subject to distinct monitoring. Importers should confirm fabric construction with the manufacturer to ensure the correct line is declared.

Classification under the folklore line requires a certificate issued by a competent authority in the exporting country attesting that the garment is a certified handmade or folklore product as recognized under the applicable US schedule note. Without that certificate, the skirt must be classified under one of the standard construction-based lines regardless of how it was made.
