Classification Of NUMBER SYSTEM

We can use a Venn diagram to illustrate this classification of number, as shown here.

Export Control Classification Number (ECCN)

Sequence number or other identifier for an internal classification subarrangement or add table. If the first or only add table found at a classification number is the number 1, and succeeding integers are used for any following add tables found at that number.

The call and classification numbers assigned using a scheme other than these:

ECCN stands for Export Control Classification Number. An ECCN is an alpha-numeric classification used in the Commerce Control List to identify items for export control purposes. AN ECCN is different from a Schedule B number, which is used by the Bureau of Census to collect trade statistics. It is also different from the Harmonized Tariff System Nomenclature, which is used to determine import duties.

A library classification is a by which library materials are arranged according to subject. Library classifications use a notational system that represents the order of topics in the classification and allows items to be stored in that order. Library classification systems group related materials together, typically arranged in a hierarchical tree structure. A different kind of classification system, called a system, is also widely used which allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in multiple ways. The library classification numbers can be considered identifiers for resources but are distinct from the (ISBN) or (ISSN) system.

There are three ways to determine the Export Control Classification Number (ECCN) for your product.

OCLC is a non-profit library cooperative, made up of thousands of member libraries throughout the world. OCLC does not sell books and the actual content is not provided in our database. Libraries add bibliographic records to WorldCat representing books and other items in their collections. The Classify prototype helps librarians apply classification numbers to resources in library collections. Only the metadata/citation is presented in Classify and WorldCat. Your local library may be able to help you gain access to a resource found through Classify and WorldCat. Classify provides a user interface and a machine service for assigning classification numbers and subject headings. The database is searchable by many of the standard numbers associated with books, magazines, journals, and music and video recordings. These numbers include: Classification schemes are used to provide a systematic arrangement of materials. The classification numbers applied to books and other materials are used to arrange items on shelves and to support browsing, filtering and retrieval of bibliographic information in online systems. The Classify prototype is designed to help users apply classification numbers.Within each Chapter, goods are listed according to a hierarchical classification system, broken down into finer and finer categories. The lowest breakdown level is called the Classification Number. This is the number that must be used on the Customs documents. There is a Classification Number for every product that anyone could ever wish to import.What do you mean by the term ‘number’? Number is a symbol representing ‘quantity’. In this we are going to learn the classification of number systems.

04 is the Chapter designation indicating that the item belongs to Chapter 4: dairy produce; birds' eggs; natural honey; edible products of animal origin not elsewhere specified or included.
04.06 is the Heading within Chapter 4, creating a more specific description of the type of dairy product: Cheese and Curd.
0406.20 is the Subheading indicating the type of cheese or curd: grated or powdered cheese of all kinds. Note that the decimal in between the first two digits and last two digits of the Heading level moves to after the first four digits in the Subheading level and below.
0406.20.90 is the Tariff Item, describing the variety of grated or powdered cheese: other than cheddar and cheddar types. The Canadian duty rate is assessed at this level. The official unit of measurement is assigned, where applicable, at this level when the Statistical Suffix is 00.
0406.20.90.20 is the Classification Number, specifying the exact type of grated or powdered cheese other than cheddar: Romano. The classification number is built by adding a two digit code, the Statistical Suffix (in this case 20) to the Tariff Item. Note that all Classification Numbers belonging to a given Tariff Item will have the same duty rate. As well, the official unit of measurement is assigned, where applicable, at this level when the Statistical Suffix is other than 00.
The Classification Number is put together in a very logical manner. Consisting of 10 digits, each digit provides specific data used to systematically produce an increasingly accurate description of the item. Because the Harmonized System was designed to be used on a global basis, the first 6 digits fulfil the international requirements while the last 4 have been designated for Country-specific Tariff and statistical purposes.Note that the digits for the Tariff Item and Classification Number levels are zeros. This indicates that no further breakdown beyond the Subheading is required and that the Subheading, Tariff Item and Classification Number levels are all encompassed by the same number. It is quite common for the last 2 digits of the Classification Number to be filled in with zeros to indicate that the duty rates and statistical classification are to be determined at the same level of detail.
