Embroidery in the Piece, Strips or Motifs — Other Textile Materials

Because 5810.99 is a residual category, CBP may scrutinize whether the fiber content truly falls outside cotton and man-made fibers. A fiber content test report from an accredited laboratory, along with the manufacturer's material specification, is the standard documentation. For wool embroidery under 5810991000, a declaration of the animal-hair fiber type (e.g., merino wool) further supports the classification.

Classification of embroidery on a blended ground follows the essential character of the ground fabric, typically determined by the predominant fiber by weight. A cotton-linen blend where cotton predominates would likely be classified under the cotton heading 5810.91 rather than 5810.99. When the blend is close to equal, a binding ruling from CBP is advisable to avoid misclassification.
