5404.19.10.00 - Racket strings

This HTS category, 5404.19.10.00, specifically covers racket strings manufactured from synthetic monofilament. The defining characteristics for inclusion are that the monofilament must have a decitex of 67 or greater, and no single cross-sectional dimension should exceed 1 millimeter. This precise specification ensures that only materials suitable for the tension and performance demands of sporting rackets are classified here.

Within the broader heading of synthetic monofilament and strip, this subcategory differentiates itself from its sibling, 5404.19.80, which encompasses "Other" synthetic monofilament, strip, and the like. The key distinction lies in the explicit designation for racket strings, implying a specific end-use and material property profile not necessarily met by other types of synthetic monofilament or strips falling under the broader "Other" category.

As a leaf node, this category does not contain further subcategories. Classification within 5404.19.10.00 is therefore determined solely by meeting the established criteria for synthetic monofilament intended for use as racket strings. Importers and exporters should ensure that the product's material composition and physical dimensions align with the decitex and cross-sectional requirements to ensure accurate classification.
