HS Code for Fiberglass rovings

Fiberglass rovings are classified under HS code 7019.12. Rovings are a specific form of glass fiber product consisting of a collection of continuous filaments gathered into a single strand without an intentional twist. This classification is determined by the physical state of the glass fiber at the time of export. Under the Harmonized System, heading 7019 covers glass fibers and their products. The sub-heading 7019.12 is specifically reserved for rovings. These are primary products used in various manufacturing processes like pultrusion, filament winding, and the production of woven rovings. The absence of a twist is the defining characteristic that separates rovings from yarns. Customs authorities look for the continuous nature of the filaments and the lack of mechanical twisting to confirm this classification. Because rovings serve as the foundational material for many composite reinforcements, their classification is strictly monitored to ensure they are not confused with processed fabrics or chopped fibers. The filaments in a roving are typically bundled in a parallel fashion, allowing for high tensile strength in specific directions, which is a key identifier during physical inspection by customs officers.

Products Included

• Single-end continuous rovings
• Multi-end (assembled) rovings
• Spray-up rovings for gun applications
• Panel rovings for translucent sheets
• SMC (Sheet Molding Compound) rovings

Common Misclassification

Fiberglass rovings are most commonly misclassified as fiberglass yarn under 7019.13. The technical difference is the twist; yarns are twisted, while rovings are not. They are also sometimes confused with chopped strands (7019.11), which are short, cut lengths of fiber rather than continuous strands. Furthermore, if the rovings have been woven into a fabric, they must be classified under 7019.61 or 7019.62, as 7019.12 only covers the raw, unwoven strand.

FAQ

What is the HS code for fiberglass rovings?

The specific HS code for fiberglass rovings is 7019.12.

What is the difference between a roving and a yarn in HS classification?

In the context of HS code 7019, rovings (7019.12) are untwisted continuous strands, whereas yarns (7019.13) have a definite mechanical twist applied to the fibers.
