The Manufacturing sector covers work performed in mechanical, physical, or chemical transformation of materials, substances, or components into new products. The assembling of component parts of manufactured products also falls under Manufacturing unless the activity is appropriately classified in Construction.
Manufacturing uses raw materials that are products of agriculture, fishing, forestry, mining, or quarrying, as well as products of other manufacturing operations.
Plants, factories, or mills that characteristically use power-driven machines and materials-handling equipment, transform the raw materials into new finished products or components of products that require further manufacturing. Manufacturing that transforms materials or substances into new products by hand or in workers homes, as well as those engaged in selling products made on the same premises from which they are sold, such as textile handcrafts, baked goods and custom-made golf clubs or fishing poles for example, to the general public are also included in this sector. Manufacturing businesses may process materials or may contract with other establishments to process their materials for them. Both types fall under the classification manufacturing.
