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 luster, softness, and durability. Silk yarn produced under this code is an important input for the manufacturing of luxury fabrics, fashion items, and home textiles, contributing significantly to the broader economy.

Production process

The production of silk yarn under HS code 5004 involves a multi-step process. First, cocoons from silkworms are harvested and the raw silk is extracted through a process called reeling. The silk filaments are then twisted and plied to create the desired yarn thickness and strength. Depending on the end-use, the silk yarn may undergo additional processing, such as dyeing, weaving, or knitting, before being distributed to manufacturers and retailers.

Production inputs

The primary input for the silk yarn industry under HS code 5004 is the raw silk harvested from silkworm cocoons. This requires a reliable supply of silkworms, as well as specialized equipment and facilities for the reeling and processing of the raw silk. Additionally, the industry relies on various chemicals, dyes, and machinery for the subsequent stages of yarn production and finishing.

Production outputs

The main output of the HS code 5004 industry is high-quality silk yarn, which is then consumed by manufacturers of 5007 Woven fabrics of silk or of silk waste and 6004 Knitted or crocheted fabrics, of a width exceeding 30 cm, containing by weight 5% or more of elastomeric yarn or rubber thread, among other textile and apparel products. The silk yarn produced under this code is highly valued for its unique properties and is often used in the production of luxury and premium-quality textiles.
