9902.12.86 - Monofilament yarn of nylon, of 53 decitex or more but not over 58 decitex, with no cross-sectional dimension exceeding 1 mm; untwisted or with twist of fewer than 5 turns/m, not put up for retail sale, fully oriented; the foregoing with consistent diameter to be suitable for silk-screening (provided for in subheading 5402.45.90)

This HTS classification, 9902.12.86, pertains to specific types of monofilament yarn made from nylon. The defining characteristics for this category include a decitex range of 53 to 58, a cross-sectional dimension not exceeding 1 mm, and a twist level of fewer than 5 turns per meter. Crucially, the yarn must have a consistent diameter suitable for silk-screening applications and is not intended for retail sale. It is important to note that this provision is found within Chapter 99, which houses temporary legislation and modifications related to trade agreements and agricultural adjustments.

This temporary classification is distinct from the permanent HTS classifications found in Chapters 1-98, particularly Chapter 54 which covers man-made staple fibers and yarns. While the physical characteristics of the yarn might align with certain descriptions under Chapter 54, the specific application for silk-screening and the temporary nature of this provision under Chapter 99 differentiate it. Unlike sibling categories in Chapter 99 that might cover other temporary restrictions or modifications, this node is narrowly focused on this particular type of nylon monofilament yarn.

As this node is a leaf node, there are no further subdivisions. The classification is complete at this level, meaning goods meeting the precise criteria outlined in the description will be classified under 9902.12.86. This implies that importers and exporters need to carefully verify that all specified physical properties and intended use (silk-screening suitability) are met to ensure correct classification and compliance with any temporary trade measures associated with this code.
