HS Code 6815.11 – Stone or other mineral substances not elsewhere specified or included; carbon fibres for non-electrical uses
HS code 6815.11 is the 6-digit subheading for stone or other mineral substances not elsewhere specified or included, carbon fibres for non-electrical uses. It is used for PAN-based carbon fibers, pitch-based carbon fibers, high-modulus carbon fibers, standard modulus carbon fibers and chopped carbon fibers.
What HS 6815.11 covers
This HS code specifically covers raw carbon fibers intended for non-electrical applications. Carbon fibers are renowned for their exceptional strength-to-weight ratio, high stiffness, and corrosion resistance, making them foundational materials in advanced composites. In international trade, these fibers are primarily imported and exported by manufacturers in the aerospace, automotive, sporting goods, and industrial sectors for structural reinforcement and lightweighting. The market is driven by the increasing demand for high-performance materials across various industries seeking to improve fuel efficiency, speed, and durability. Key considerations include fiber type (e.g., PAN-based, pitch-based), tensile strength, modulus, and compatibility with different resin systems for composite manufacturing.

Codes often confused with 6815.11
Common mistake. This code is distinct from 681512 (carbon fiber fabrics) and 681513 (articles of carbon fiber), focusing solely on the raw "fibres" themselves, and excludes carbon fibers for electrical uses.
Top exporters and importers of HS code 681511, 2025
In 2025, the largest exporter of HS code 681511 in UN Comtrade data was the United States, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 16% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
