About silk; yarn (other than yarn spun from silk waste), not put up for retail sale

HS code 5004 covers the trade and production of silk yarn, excluding yarn spun from silk waste. This industry plays a vital role in the global textile and apparel supply chain, providing a high-quality natural fiber that is prized for its softness, luster, and durability. Silk production is particularly important in countries with established silk-weaving traditions, such as China, India, and Italy, where it contributes significantly to the local and national economies.

Production process

The production of silk yarn involves several key steps. First, silk cocoons are harvested from silkworms, and the raw silk fibers are extracted through a process called reeling. The silk fibers are then twisted and spun into yarn, which can be dyed, woven, or knitted into a variety of textile products. Advances in technology have also enabled the development of innovative silk-blending techniques, allowing manufacturers to create unique fabric blends that combine the natural properties of silk with other fibers.

Production inputs

The primary input for the silk yarn industry is, of course, the raw silk fiber. Silkworms, which feed on mulberry leaves, are the source of this natural fiber. In addition to the raw silk, the industry also relies on various chemicals, dyes, and specialized machinery for the spinning, weaving, and finishing processes. Skilled labor, particularly in the areas of silk reeling and weaving, is another crucial input for this industry.

Production outputs

The main output of the silk yarn industry is, naturally, silk yarn itself. This yarn is then consumed by a wide range of industries, including 5007 Woven fabrics of silk or of silk waste, 6004 Knitted or crocheted fabrics, of a width exceeding 30 cm, containing by weight 5% or more of elastomeric yarn or rubber thread, and 6214 Shawls, scarves, mufflers, mantillas, veils and the like, among others. The high-quality and unique properties of silk make it a sought-after material for luxury apparel, home textiles, and various specialty applications.
