8447.12.90.20 - Cylinder and dial machines

This classification pertains to circular knitting machines featuring a cylinder diameter exceeding 165 mm, specifically those that are not open-top cylinder machines. These machines are designed for the production of knitted fabrics in a circular manner, with the diameter of the knitting cylinder being a key defining characteristic. The scope encompasses a variety of industrial knitting equipment used for producing tubular fabrics with a wide range of stitch structures and patterns.

Distinguishing this category from its sibling, 8447.12.90.10, is the exclusion of machines specifically identified as "open-top cylinder machines." While both fall under circular knitting machines with a cylinder diameter over 165 mm, this code captures those that do not meet the criteria for the "open-top" designation, implying differences in design, operational features, or the types of fabrics they are best suited to produce. The residual category, 8447.12.90.90, serves as a further catch-all for any other circular knitting machines within the specified diameter range that do not fit the more specific criteria.

As this classification represents a leaf node within the HTS, there are no further subcategories. Therefore, the classification is concluded at this level, with the defining characteristics being the machine type (circular knitting machine), the cylinder diameter exceeding 165 mm, and the exclusion of the "open-top" feature. Importers should carefully review the design and operational specifics of their circular knitting machinery to ensure accurate classification under this heading or its sibling categories.
