RFL Impregnated Fiberglass Cord 9-Micron
Electrically nonconductive continuous fiberglass filaments measuring 9 microns in diameter, twisted into cord and impregnated with resorcinol formaldehyde latex (RFL) for superior adhesion to rubber compounds. Used primarily as reinforcement in high-strength rubber belts and hoses. Classified under HTS 7019.19.70.00 due to its specific filament size and RFL treatment meeting the exact subheading criteria.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If filaments under 9 microns in diameter
Finer filaments (less than 9 microns) fall into separate statistical suffix for ultra-fine fiberglass reinforcing cord.
If further processed into rubber tire cord fabric
When woven into textile fabric and coated with rubber, it becomes tire cord fabric under Chapter 59 textile-rubber composites.
If silica content below 60% without qualifying oxides
Fails Chapter 70 glass wool/fiber definition per notes, treated as mineral wool substitute under Chapter 68.

Import Tips & Compliance
• Verify filament diameter (9-11 microns) and RFL impregnation via lab testing, as deviations shift classification to other 7019 subheadings
• Provide supplier certificates confirming electrical nonconductivity and treatment formulation to avoid customs reclassification
