8447.11.90.20 - Cylinder and dial machines

This HTS category, 8447.11.90.20, specifically covers "cylinder and dial machines" within the broader group of circular knitting machines with a cylinder diameter not exceeding 165 mm. These machines are designed for producing knitted fabrics and items using a circular needle arrangement. The "cylinder and dial" designation refers to machines that utilize both a cylinder of needles and a dial of needles to create a variety of knitted structures.

Distinguishing this category from its sibling, 8447.11.90.10 ("Open-top cylinder machines"), is the presence and function of a dial mechanism in addition to the cylinder. While open-top cylinder machines primarily rely on needles in the cylinder for knitting, machines classified under 8447.11.90.20 incorporate a dial which can perform additional knitting operations, allowing for more complex stitch formations and pattern capabilities. The "Other" designation at this level (8447.11.90.90) implies that machines not fitting the specific description of "open-top cylinder" or "cylinder and dial" would fall under that broader category.

As a leaf node, this classification does not have further subcategories. Therefore, classification within 8447.11.90.20 is determined by the specific construction and operational characteristics of the knitting machine, namely its circular knitting mechanism, cylinder diameter not exceeding 165 mm, and the combined use of both cylinder and dial needle beds for fabric production. Examples would include machines capable of producing ribbed fabrics, interlock knits, or specialized patterned fabrics that require the coordinated action of both needle sets.
