Note. according to customer requirements, retail merchandise exports to North America may be a 12-bit code.
4.2 Principles of preparation of the code
Retail commodity code is a unified whole, it should be applied in the overall commodity circulation process. The preparation of retail commodity code, shall comply with
Under basic principles.
4.2.1 The only principle
4.2.1.1 assigned the same commodity same commodity code, the same basic characteristics as the same commodity items.
4.2.1.2 different commodities should be assigned different product codes, the basic characteristics of different commodities as different commodities.
Note. Under normal circumstances, the basic characteristics of the goods including trade names, trademarks, type, size, quantity, type of packaging and other product characteristics. Enterprises according to the line
Features industry and its own product management demand for the product is assigned a unique product code.
4.2.2 The principle of non-meaning
Retail commodity code commodity item code does not indicate the specific commodity-related information.
4.2.3 stability principle
Retail commodity code Once assigned, if the basic characteristics of the goods does not change, it should remain unchanged.
Preparation 4.3 code
4.3.1 compiled separately packaged single retail commodity code
Individually wrapped single retail means alone, can not be divided individually packaged retail merchandise. Preparation of their commodity codes are often
4.1.1 under the 13 code structure. When the packaging of goods is very small, in line with any one of the following three conditions may apply for the use of
4.1.2 prescribed code structure 8.
--- 13 Code bar code symbols printed product label area of more than a quarter of the largest surface area or the entire printable area
One-eighth of the time;
--- The largest surface area of less than 40cm2 product label or all of the printable area of less than 80cm2 time;
--- The product itself is a cylinder diameter of less than 3cm.
4.3.2 preparation of compositions packaged retail commodity code
4.3.2.1 preparation of standard packs of retail commodity code
Standard packs retail commodity refers to the same standard by a plurality of individual commodity composition of stable combinations of packaged goods. its
Preparation of commodity codes are often 13-bit code structure, but not with the same code is contained within a single package goods.
4.3.2.2 preparation of mixed composition packaged retail commodity code
Mixed composition packaged retail standards set by means of a plurality of different individual commodity composition of stable combinations of packaged goods. its
Preparation Product code usually 13 code structure, but the same code is not contained within the packaging of goods.
Preparation 4.3.3 variable retail commodity code
Code variables for retail store or inside a closed system of consumer goods unit. Their choice commodity codes can be found GB/T 18283.
