Black Carbon-Coated Glass Yarn from United States
Black carbon-coated glass yarn is a continuous E-glass filament yarn pigmented with carbon black, giving it a conductive surface for use in electronic composite applications. The carbon coating is microscopically thin, so the yarn retains the essential character of glass fibre yarn and is classified as other yarn of glass fibres under tariff item 7019.13.00.

Import Tips
• Ensure the carbon coating is microscopically thin and does not alter the yarn's glass fibre character, as thicker coatings could shift classification
• Declare the yarn's end use in electronics to support the tariff classification if questioned by CBSA
• Keep supplier technical data sheets showing the coating thickness and glass composition
