Excluded from this subsector are establishments that weave or knit fabric and make garments. These are included in subsector 315, Apparel Manufacturing. Knitting, when done alone, is classified in Textile Mills subsector; but when knitting is combined with the production of complete garment, the activity is classified in Apparel Manufacturing.314 Textile Products MillsThe manufacturing of textile products (except apparel) from purchased fabric is classified in this subsector. Processes used in this subsector are generally cut and sew (i.e. purchasing fabric and cutting and sewing to make nonapparel textile products, such as sheets （被单） and towels （毛巾）).315 Apparel ManufacturingIndustries in this subsector group establishment with two distinct manufacturing processes: (1) cut and sew (i.e., purchasing fabric and cutting and sewing to make a garment) and (2) the manufacture of garments in establishments that first knit fabric and then cut and sew the fabric into a garment.316 Leather and Allied Product ManufacturingEstablishment in this subsector transform hides (兽皮) into leather by tanning （鞣革）or curing and fabricating （制造）the leather into products for final consumption. It also includes the manufacture of similar products from other materials, including products (except apparel) made from “leather substitutes （代用品）”, such as rubber, plastics, or textiles. Rubber footwear, textile luggage, and plastics purses or wallets are examples of “leather substitutes” Specific for establishments engaged in footwear manufacturing, there is:3162Footwear Manufacturing321 Wood Product ManufacturingIt includes establishments that make wood products from logs and bolts that are sawed （锯）and shaped （成形）, and establishments that purchase sawed lumber and make wood products.322 Paper ManufacturingIt includes the manufacturing of pulp（纸浆）and manufacturing of converted paper products.323 Printing and Related Support ActivitiesIndustries in this subsector print products, such as newspapers, books, periodicals （期刊）, business forms, greeting cards, and other materials, and perform support activities, such as bookbinding（装订）, platemaking（制版）services, and data imaging. This industry comprises establishments engaged in printing on apparel and textile products, paper, metal, glass, plastics, and other material, except fabric (grey goods). Establishments in this industry do not manufacture the stock that they print but may perform postprinting activities, such as bending, cutting, or laminating the materials they print, and mailing.324 Petroleum and Coal Product ManufacturingThis subsector is based on the transformation of crude petroleum and coal into usable products. The dominant process is petroleum refining（精炼）and further process of refined petroleum and coal products.325 Chemical ManufacturingIt is based on the transformation of organic（有机）and inorganic（无机）raw materials by a chemical process and the formulation of products. However, it does not include any transforming raw chemicals by a chemical process. Examples are: manufacturing of dye（染色）, pigment（颜料）, resin（树脂）, synthetic（人造）rubber, pesticides（农药）, fertilizers（肥料）, pharmaceutics（配药）, medicine, paint and coating, soap and cleaning compound.326 Plastics and Rubber Products ManufacturingThis subsector make goods by processing plastics material and raw rubber. Examples are: manufacturing of plastic bag, laminated sheet, polystyrene foam, plastic bottle and containers, rubber hoses and tubing.327 Nonmetallic Mineral Product ManufacturingThis subsector transforms mined or quarried nonmetallic minerals, such as sand, gravel, stone, clay and refractory materials into products for intermediate or final consumption. This subsector includes establishments that manufacture products, such as bricks, refractories, ceramic products; and glass and glass products, such as plate glass and container. Also included are cement and concrete products.3271 Clay Product and Refractory Manufacturing3272 Glass and Glass Product Manufacturing331 Primary Metal ManufacturingIndustries in this subsector smelt（熔炼） and/or refine ferrous（含铁的） and nonferrous metals from ore（矿石）, pig or scraps; manufacture metal alloys（合金） and superalloys（超合金）.332 Fabricated Metal Product ManufacturingIndustries in this subsector transform metal into intermediate or end products. Important fabricated metal processes are forging（锻造）, stamping, forming, and machining, used to shape individual pieces of metal; and other processes, such as welding（焊接） and assembling, used to joint separate parts together.333 Machinery ManufacturingSimilar to those used in metal fabricating establishments, machinery manufacturing is different because it typically employs multiple metal forming processes in manufacturing the various parts of the machine.334 Computer and Electronic Produce ManufacturingIt involves the manufacture of computers, computer peripherals（外围的）, communications equipment, and similar electronic products.335 Electrical Equipment, Appliance, and Component ManufacturingIndustries in this subsector manufactures products that generate, distribute and use electrical power. For examples: electric lighting equipment, household appliance, motors, transformer, batteries, wiring devices, etc.336 Tran
