HS Code for Chopped glass fiber

Chopped glass fiber is classified under HS code 7019.11. This classification is determined by the material composition and the specific physical form of the glass. Chapter 70 of the Harmonized System encompasses glass and glassware, while heading 7019 specifically addresses glass fibers (including glass wool) and articles thereof. Within this heading, the 7019.1x series focuses on mechanical intermediates such as slivers, rovings, yarn, and chopped strands. Subheading 7019.11 is strictly reserved for chopped strands that have been cut to a length of not more than 50 mm. These fibers are typically produced by drawing molten glass through bushings and then mechanically chopping the resulting filaments into precise lengths. The classification depends strictly on the length measurement; if the strands exceed 50 mm, they would fall under a different subheading. These products are essential reinforcement materials in composite manufacturing, particularly for injection molding and compression molding processes where they are mixed with resins to enhance mechanical properties.

Products Included

• Chopped strands for Bulk Molding Compounds (BMC)
• Chopped strands for Sheet Molding Compounds (SMC)
• Thermoplastic grade chopped glass fibers
• Alkali-resistant (AR) chopped glass strands for concrete reinforcement
• Water-dispersible chopped glass fibers

Common Misclassification

Chopped glass fiber is frequently confused with HS code 7019.12, which is specifically for rovings. Rovings are continuous strands, whereas 7019.11 must be cut under 50mm. It is also sometimes misclassified under 7019.19, which covers other glass yarns and slivers that do not meet the chopped or roving definitions. Additionally, importers may mistakenly look at heading 6806, which covers mineral wools; however, glass fibers are explicitly excluded from Chapter 68 when they fall under the definitions of Chapter 70.

FAQ

What is the HS code for chopped glass fiber?

The specific HS code for chopped glass fiber strands with a length not exceeding 50 mm is 7019.11.

How is the length of chopped glass fiber measured for customs?

Customs authorities measure the individual strand length; if the average length is 50 mm or less, it remains in 7019.11. If it exceeds this, it is classified under 7019.19.
