Carbon fiber Hs Code

Carbon fiber harmonized system code

Product Overview Carbon fiber classified under HS Code 681511 refers to high-strength, lightweight fibers composed primarily of carbon atoms bonded in a crystal lattice structure. These fibers typically exhibit tensile strengths exceeding 3,500 MPa and modulus values ranging from 230 to 600 GPa, with diameters between 5 to 10 microns. The product encompasses various processing levels, including unidirectional fibers, woven fabrics, and pre-impregnated materials (prepregs), all manufactured to stringent quality standards ensuring consistent mechanical properties and minimal defects. Within HS Code 681511, subcategories differentiate fibers by carbon content, surface treatment, and sizing agents applied to enhance compatibility with resin matrices. Commercially, carbon fiber is extensively utilized across food service equipment manufacturing, retail packaging components, and processing machinery frameworks due to its superior strength-to-weight ratio, corrosion resistance, and thermal stability. Its market positioning is anchored on delivering enhanced durability and performance at optimized weight, facilitating improved product lifecycle and operational efficiency for industrial applications. HS Code Classification & Trade Specifications The full HS Code 681511 is structured as follows: Chapter 68 (Articles of stone, plaster, cement, asbestos, mica or similar materials), Heading 6815 (Articles of carbon fibers or articles of graphite or other carbon in the form of fibers), and Subheading 681511, specifically denoting carbon fibers. This classification is predicated on the product’s chemical composition and physical form, distinguishing carbon fiber materials from other carbon-based products. Trade professionals recognize that carbon fiber under this code requires packaging in moisture-resistant, inert containers to prevent contamination and degradation, often with desiccants included to maintain low humidity levels during transit. Preservation methods may involve vacuum-sealing or nitrogen flushing to inhibit oxidation. Shipping protocols mandate secure, vibration-damped palletization to prevent fiber damage. Quality standards adhered to include ISO 2076 for textile carbon fibers and ASTM D4018 for tensile testing, ensuring compliance with WTO trade requirements and facilitating smooth customs clearance. This classification framework supports accurate tariff application, risk assessment, and regulatory adherence in international trade operations.
