9902.12.96 - Monofilament of nylon, of 67 decitex or more and of which no cross-sectional dimension exceeds 1 mm; designed with consistent diameter to be suitable for silk-screening (provided for in subheading 5404.19.80)

HTS 9902.12.96 specifically classifies monofilament made of nylon that meets precise technical specifications. These specifications include a decitex of 67 or more, and crucially, no cross-sectional dimension exceeding 1 millimeter. The defining characteristic for this classification is its design with a consistent diameter, making it suitable for silk-screening applications. This particular item is provided for under subheading 5404.19.80, indicating its original classification within the broader category of synthetic monofilament of polyamides.

This classification is unique within Chapter 99, which generally pertains to temporary legislation and modifications. Unlike the broad categories of live animals or agricultural products found at higher levels of the HTS, 9902.12.96 addresses a very specific manufactured good with a defined industrial purpose. Its siblings, which are numerous and diverse, would cover entirely different types of goods. The temporary nature of Chapter 99 suggests this classification may be subject to change based on trade agreements or specific import restrictions.

As this is a leaf node, there are no further subcategories under HTS 9902.12.96. This means that once a product meets the precise criteria outlined in the description – nylon monofilament, 67 decitex or more, cross-section not exceeding 1 mm, and designed for silk-screening with consistent diameter – it is definitively classified here. The classification relies solely on the physical and functional attributes of the monofilament itself, as referenced by its base classification in 5404.19.80.
