Last updated: August 2026 dataSilk waste in its raw, unprocessed form—encompassing cocoons unsuitable for reeling, yarn waste from throwing or weaving operations, and garnetted stock—is a commercially distinct input from reeled or thrown silk. The 'not carded or combed' qualifier is the classification boundary: once waste silk is processed through carding or combing, it moves to a spun-silk preparation heading. This material is used to produce spun silk yarn and lower-cost silk blended fabrics, and its price is closely tied to the availability and quality of primary silk production in major sericulture regions.

Silk waste under this heading includes cocoons that cannot be reeled (pierced, double, or damaged), waste generated during throwing and weaving (yarn ends, broken filaments), and garnetted stock—previously manufactured silk goods that have been mechanically broken down into fiber. All must be in an uncarded, uncombed state to remain in this heading.
Silk waste grades vary significantly by fiber length, cleanliness, and origin. Long-staple waste from throwing operations commands higher prices and is suitable for finer spun silk yarns, while short-staple or heavily contaminated waste is used in coarser blends or non-textile applications such as silk protein extracts. Buyers should specify waste type and grade in contracts, as pricing and end-use suitability differ substantially across grades.
