HS Code for Silk thread

Silk thread intended for consumer use is classified under HS code 5006.00. This code specifically covers silk yarn and yarn spun from silk waste that has been put up for retail sale. In the context of the Harmonized System, "put up for retail sale" refers to yarn wound on supports (like reels, tubes, or cards) or in hanks and skeins of a specific limited weight. This classification is distinct from industrial silk yarns which are imported in bulk for textile manufacturing. The inclusion of silk-worm gut in this heading further consolidates specialized silk filaments used for non-medical purposes under this single classification.

Products Included

• Silk sewing thread on reels for retail
• Embroidery silk thread in small skeins
• Silk yarn for hand-knitting put up for retail

Common Misclassification

The most frequent misclassification occurs with HS code 5004.00 (silk yarn not for retail) and 5005.00 (yarn spun from silk waste not for retail). These codes are for industrial-sized bobbins or cones used in factories. If the thread is synthetic but looks like silk, it must be classified under 5401.10 (synthetic sewing thread). Importers often confuse silk thread with "silk-like" polyester thread, which leads to significant duty discrepancies as Chapter 50 is strictly for natural silk.
