5002.00.00.00 - Raw silk (not thrown)

This HTS category, 5002.00.00.00, specifically covers raw silk, which refers to silk fibers that have been reeled from cocoons but have not yet undergone any further processing such as throwing (twisting) or degumming. This classification is exclusive to silk in its most rudimentary, natural state as harvested and prepared for subsequent manufacturing. It encompasses silk fibers that are still in the process of being wound off the silkworm cocoons, retaining their natural sericin gum.

Within Section XI, Chapter 50, which broadly deals with silk and silk products, 5002.00.00.00 distinguishes itself from other potential silk classifications by its raw, unprocessed nature. For example, it would not include "thrown" silk (prepared for weaving or knitting), spun silk (made from silk waste), or degummed silk, all of which represent further stages of processing and fall under different HTS codes. It is important to note that this is a terminal classification, meaning there are no further subdivisions within this specific code.

Therefore, any product imported or exported that consists of silk fibers directly reeled from cocoons, without any twisting, spinning, or removal of the natural gum, will be classified under 5002.00.00.00. Proper identification relies on the physical state of the silk, specifically the absence of throwing processes which are indicative of preparation for yarn manufacturing.
