8447.11 - With cylinder diameter not exceeding 165 mm:

This HTS category, 8447.11, specifically covers circular knitting machines with a cylinder diameter that does not exceed 165 millimeters. These machines are designed for the automated creation of knitted fabrics and articles in a circular formation. Their primary function is to interlock yarns to produce a seamless tubular fabric or specific knitted items, distinguishing them from other types of knitting machinery.

The key distinguishing feature of 8447.11 compared to its sibling category, 8447.12, lies solely in the physical dimension of the cylinder. While both are circular knitting machines, 8447.11 is reserved for those with a cylinder diameter measuring 165 mm or less. In contrast, 8447.12 encompasses machines with a cylinder diameter exceeding this specified limit. This diameter is a critical factor in determining the size and type of knitted products each machine can produce.

Within this category, further subdivisions exist to refine the classification based on the intended application of the circular knitting machine. The subcategory 8447.11.10.00 is designated for machines specifically designed for knitting hosiery, such as socks and stockings. All other circular knitting machines fitting the diameter criteria and not used for hosiery production fall under the broader residual subcategory 8447.11.90.
