HS Code for High twist nylon yarn
High twist nylon yarn is classified under HS code 5402.51 based on its chemical composition and physical structure. This code specifically covers synthetic filament yarns made of nylon or other polyamides that are single (not plied) and have a twist exceeding 50 turns per metre. To qualify for this classification, the yarn must not be textured and must not be high tenacity yarn, which are covered under different subheadings. The classification also requires that the yarn is not prepared for retail sale and is not classified as sewing thread under heading 5401. The technical distinction of "high twist" is critical because the twist level affects the yarn's torque, strength, and the final hand of the fabric. Additionally, the monofilament component must be less than 67 decitex. This classification ensures that industrial-grade nylon filaments used in weaving and knitting are distinguished from consumer-ready products or specialized industrial cords.
Products Included
- Single nylon 6 filament yarn with 60 turns per metre
- Single nylon 6,6 filament yarn with 100 turns per metre
- Non-textured polyamide monofilament (under 67 decitex) with high twist
- Industrial nylon yarn on large beams for weaving
Common Misclassification
This code is frequently confused with HS code 5402.31, which is reserved for textured nylon yarns. Even if a yarn has a high twist, if it has undergone a texturing process to add bulk, 5402.31 takes precedence. Another common error is using 5402.11, which is for high tenacity nylon yarn; high tenacity is defined by specific breaking tenacity thresholds (above 60 cN/tex) in the Section XI legal notes. Furthermore, if the twist is 50 turns per metre or less, the yarn should be classified under 5402.45.
