5404.19 - Other:

This HTS category, 5404.19, encompasses synthetic monofilament and strips that meet specific physical criteria but are not classified under the "Elastomeric" or "Other, of polypropylene" subheadings. The core defining characteristics are that the monofilament must have a decitex of 67 or more, and none of its cross-sectional dimensions can exceed 1 millimeter. Similarly, strips and similar materials, such as artificial straw, must be made of synthetic textile materials and have an apparent width not exceeding 5 millimeters.

This classification serves as a residual category within the broader "Monofilament" group. It distinguishes itself from the sibling category 5404.11 by excluding elastomeric materials, which are typically characterized by their significant stretch and recovery properties. Furthermore, it differs from 5404.12, which is specifically designated for monofilament and strips made from polypropylene. Therefore, 5404.19 applies to synthetic monofilaments and strips composed of materials *other than* elastomers or polypropylene that meet the general size specifications.

Within this category, further distinctions are made to refine classification. Subcategory 5404.19.10.00 specifically covers racket strings, highlighting a particular application for these synthetic materials. The remaining items that fit the general description but are not racket strings fall under the residual subheading 5404.19.80, "Other." This subdivision acknowledges the diverse range of synthetic monofilaments and strips that may not have a dedicated subheading but still conform to the broader criteria of this chapter.
