8452.90.20 - Other parts of sewing machines

This HTS category, 8452.90.20, encompasses a broad range of components specifically manufactured for use in sewing machines, excluding complete sewing machines themselves or their dedicated furniture and covers. This includes items such as internal mechanical parts, electrical components intrinsic to the sewing machine's operation, and accessories that are integral to the machine's function, but do not constitute the entire machine or its external housing.

It is important to distinguish this category from its sibling, 8452.90.10, which specifically covers furniture, bases, and covers designed for sewing machines, as well as parts of such furniture. While both fall under the broader heading for sewing machine parts, 8452.90.20 focuses on the operational components of the machine, rather than its external support structures or protective coverings.

To further refine classification, this category is divided into two subcategories. Subcategory 8452.90.20.10 is designated for parts of household sewing machines, while 8452.90.20.90 covers all other parts of sewing machines, typically pertaining to industrial or commercial models. This distinction is crucial for accurate duty assessment based on the intended end-use and scale of the sewing machine to which the parts belong.
