HS Code for Glass fiber threads
Glass fiber threads are classified under HS code 7019.19, which serves as a specific category for glass fibers and articles thereof that are not mechanically or chemically bonded into mats, and specifically those that do not meet the technical definition of yarns or slivers. The classification is determined by the physical state of the glass filaments. These threads are typically produced through the extrusion of molten glass through platinum-rhodium bushings, resulting in fine filaments. Under the Harmonized System, heading 7019 covers a wide range of glass fiber products, but sub-heading 7019.19 is reserved for threads, chopped strands, and rovings that are distinct from the twisted structures found in yarns. The classification depends on the absence of a specific twist or plying that would otherwise categorize the material as a yarn under 7019.13. These threads are essential in the production of composite materials, providing structural reinforcement without the bulk of woven fabrics.
Products Included

Common Misclassification
The most frequent misclassification occurs with HS code 7019.13, which is designated for glass fiber yarns and slivers. The primary distinction lies in the mechanical structure; yarns are typically twisted or plied, whereas threads under 7019.19 are often untwisted filaments or rovings. Additionally, 7019.31 is often confused with this code when the threads are lightly bonded into a mat-like form, but 7019.31 requires specific mechanical or chemical bonding. Another common error involves 7019.11, which is strictly for chopped strands of a length not exceeding 50 mm.
FAQ
What is the HS code for glass fiber threads?
The primary HS code for glass fiber threads, including rovings and chopped strands not exceeding specific lengths, is 7019.19.
Are glass fiber threads the same as glass yarn?
No, for customs purposes, glass yarn (7019.13) consists of twisted filaments, while glass fiber threads (7019.19) generally refer to untwisted filaments or rovings used for reinforcement.
