Silk yarn and yarn spun from silk waste; put up for retail sale, and silk-worm gut

HS code 500600 covers a vital segment of the global textile industry - the production and trade of silk yarn and yarn spun from silk waste. Silk, one of the oldest and most luxurious natural fibers, has long been prized for its exceptional softness, luster, and durability. The silk industry plays a significant role in the economies of major silk-producing nations, providing employment and income to millions of people involved in sericulture, yarn production, and textile manufacturing.

The production of silk yarn and yarn spun from silk waste involves several key steps. First, silk cocoons are harvested from silk worms and the raw silk is extracted through a process called reeling. The silk filaments are then twisted and spun into silk yarn, which can be dyed, woven, or knitted into a variety of textile products. Yarn spun from silk waste, a byproduct of the silk reeling process, is also an important output under this HS code.

The primary inputs for the silk yarn and silk waste yarn industry include raw silk cocoons, silk waste fibers, and specialized machinery for silk reeling, spinning, and yarn processing. Skilled labor, particularly in the areas of sericulture and yarn production, is also a critical input. Additionally, the industry relies on a range of supporting industries, such as dye manufacturers and textile finishing providers, to create the final silk textile products.

The main outputs of the 500600 industry are silk yarn and yarn spun from silk waste, which are then used as inputs for a wide range of textile products. These include 500710 Woven fabrics of silk or of silk waste, 500720 Woven fabrics obtained from high-tenacity yarn of nylon or other polyamides, of polyesters or of viscose rayon, and 500790 Other woven fabrics of silk or of silk waste.
