Sandstone;. whether or not roughly trimmed, cut, by sawing etc, into blocks or slabs of a rectangular (including square) shape

HS code 251620 covers sandstone, a sedimentary rock that has been widely used in construction, architecture, and landscaping for centuries. As a versatile and durable material, sandstone plays a crucial role in the global building materials industry, contributing to the development of infrastructure, residential and commercial properties, and various other applications. This code encompasses sandstone that has been roughly trimmed, cut by sawing, or otherwise processed into rectangular or square blocks and slabs, making it ready for further use in a variety of projects.

The production of sandstone blocks and slabs typically involves a multi-step process. First, sandstone is extracted from quarries or mines using heavy machinery, such as excavators and loaders. The raw sandstone is then transported to processing facilities, where it undergoes various cutting and shaping techniques. This may include sawing, splitting, or trimming the stone to the desired dimensions using specialized equipment. The processed sandstone blocks and slabs are then carefully inspected, graded, and prepared for distribution and use in construction, landscaping, and other applications.

The primary input for the production of sandstone blocks and slabs is, of course, the raw sandstone material. This natural resource is found in various geological formations around the world and is typically extracted from quarries or mines. In addition to the raw sandstone, the industry also requires specialized machinery and tools for cutting, shaping, and finishing the stone, as well as transportation and logistics services to move the finished products to market. Energy sources, such as electricity or fuel, are also necessary for powering the production equipment.

The primary output of HS code 251620 is sandstone blocks and slabs, which are used in a wide range of applications. These products are often used in construction, such as for building foundations, walls, and facades, as well as in landscaping projects, including walkways, patios, and retaining walls. Sandstone blocks and slabs may also be used in the production of 251612 Monumental or building stone, cut or sawn, merely cut or sawn, with a flat or even surface, which is covered under a different HS code. Additionally, the waste and byproducts generated during the production process may be used in other industries, such as for aggregate in road construction or as a filler material.
