Stone or other mineral substances not elsewhere specified or included; carbon fibres for non-electrical uses

HS v2022 Code: 681511

About stone or other mineral substances not elsewhere specified or included; carbon fibres for non-electrical uses

HS code 681511 covers a diverse range of stone, mineral, and carbon fiber products that have a wide variety of industrial and commercial applications. These materials are essential inputs for numerous manufacturing and construction industries, making them a crucial component of the global economy. The products under this code play a vital role in the production of everything from building materials to advanced composites, highlighting their importance across multiple sectors.

Production process

The production techniques for the products covered by HS code 681511 can vary significantly depending on the specific material. Stone and mineral substances may be extracted from quarries or mines, then processed through cutting, grinding, or polishing to achieve the desired shape and finish. Carbon fibers, on the other hand, are typically produced through a multi-step process involving the pyrolysis of precursor materials, such as polyacrylonitrile (PAN) or pitch.

Production inputs

The main inputs required for the industries covered by HS code 681511 include raw materials such as various types of stone, minerals, and carbon-based precursors. Additionally, specialized machinery and equipment for extraction, processing, and fabrication are essential. Energy sources, such as electricity or natural gas, are also necessary for the production of these materials. 842139 Machinery for filtering or purifying gasesand 848180 Taps, cocks, valves and similar appliances for pipes, boiler shells, tanks, vats or the like may be used in the production process.

Production outputs

The products covered by HS code 681511 are used as inputs for a wide range of industries, including 680100 (Setts, curbstones and flagstones, of natural stone (except slate)), 680221 (Marble, travertine and alabaster, merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape), 680293 (Granite, merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape), and 680420 Millstones, grindstones, grinding wheels and the like, without frameworks, for grinding, sharpening, polishing, trueing or cutting, hand sharpening or polishing stones, and parts thereof, of natural stone, of agglomerated natural or artificial abrasives, or of ceramics. These materials are also used in the production of advanced composites and other specialized applications.

Revisions to 681511

Classification codes are adjusted frequently. The code may have been revised or replaced between system versions. The table below shows the history (newest to oldest) of the code 681511. The most recent 1 version of this code (681511) is in the HS v2022 system (this version):
