Yes. Narrow fabrics containing rubber or elastomeric yarns are classified under specific HTS headings for elastic fabrics, separate from non-elastic narrow wovens. The proportion of elastic yarn by weight and whether the fabric is woven or knit both influence which subheading applies, so fiber composition and construction details must be clearly stated on entry documentation.

Lace is formed by looping, twisting, or knotting threads without a ground fabric, while Schiffli embroidery is stitched onto a base that is later removed. CBP distinguishes the two by production method: true lace falls under HTS Chapter 58 lace headings, whereas Schiffli embroidery is classified under embroidery headings in the same chapter. Misidentifying one as the other is a common classification error that can result in duty underpayment.
