The tailoring adopts a simple plane structure, but is centered on the human body. The basic shape is rectangular, such as Chinese cheongsam. , Japanese kimono, etc. 2. Classification according to the wearing combination, use, fabric and production process of clothing (1) Classification according to the wearing combination There are roughly the following classifications: 1.

The Harmonized Commodity Description and Coding System (The Harmonized Commodity Description and Coding System) classified according to HS codes is referred to as the Harmonized System (HS). It is based on the "Customs Cooperation Council Classification Catalog" (CCCN) and the United Nations "Standard International Trade Classification" (SITC) It is a multi-purpose international commodity classification catalog that refers to other major international tax, statistical, transportation and other classification harmonization systems. HS code uses a six-digit code to represent its classification code. The first two digits represent the chapter. The third and fourth digits represent the position of each product in the chapter (arranged in order of processing level). The first to fourth digits represent the code. is Heading, and the following fifth and sixth digit codes are called Subheading. The first six digit codes are consistent in all countries. After the seventh digit, each country develops the number of codes according to its own needs. Clothing belongs to Category 11 and Chapters 61 and 62 of the HS classification system. Chapter 61 is knitted or crocheted products, numbered from 6101.1000-6101.9000***120, and Chapter 62 is non-knitted or non-knitted products. Crocheted clothing and accessories. Applicable to any textile products except batting. The numbers range from 6201.1100-6217.9000, with a maximum of 155 codes, which are classified according to different styles, genders, ages, and raw materials. For example, the HS number of cotton men's down coats is: 6201.1210, cotton The HS code for women's down coats is 6202.1210. There are specific requirements for the gender of clothing in the clothing HS code classification, that is, the gender is divided into men's, boys, women's, girls, and infants; the left placket above the right placket belongs to men, and vice versa belongs to women. Neutral clothing belongs to Female category. The ordering of needle and woven garments and clothing accessories is from outerwear to underwear according to product characteristics. The needle and woven products correspond to each other, and then other products.

Crocheted women's tops, corresponding to 6204.3100, women's tops made of wool or fine animal hair. 5. Classification according to the production and processing characteristics of knitted clothing (1) Classification of wool knitted clothing 1.

(2) Classification of cotton knitted clothing 1. Classification according to the production method of the fabric Knitted clothing fabrics are divided into two categories: warp knitting and weft knitting according to the production method. 2． Classification according to the organizational structure of the fabric. The basic structures of single-comb warp knitting of warp knitted fabrics include warp plain weave, warp satin weave, warp velvet weave, etc. However, in actual production, double-comb or multi-comb warp knitting is generally used as outerwear or shirts.

The program inspects all types of clothing and ultimately produces clothing that satisfies customers.
