Subjects of research: cotton filament and its product (the cotton filament, cotton wool, waste cotton and textile cleaning plant).
Purpose of work: research the new codes of goods Nomenclature to foreign economic activity, create and use in practice methods of expert tests goods of operation undertaking for determination of cotton filament and its some products.
Methods of research: study of the research work is founded on experimental method of the analysis. For determination of the chemical composition of goods and cheese are used classical chemical and technical methods, as well as physical, customs and the other expert operations of the chemical science.
The results obtained and their novelty: On the base of the complex research works for cotton fibres arc designed 10 new code numbers and commentaries to him; for product from cotton filament - 4; for cotton fibre - 4; for product cotton cleaning plant - 4; for cotton wool - 6. In generally - 28 code numbers and commentary for it. Designed scicntifically-mcthodical bases of the determination of the codes of goods is on Goods Nomenclature to foreign economic activity. Coming from results of the studies and their deep analysis, for the first time, in customs system of the Republic Uzbekistan, is created customs expert laboratory. In practical activity of the central and regional expert laboratories arc introduced designed scicntifically-mcthodical bases and new methods, especially in realization of the customs expert operation. For determination code numbers cotton filament and its product and goods on Goods Nomenclature to foreign economic activity, as well as undertaking the customs expert operation, is designed "express" methods.
Determined that with the measures of changcing of the sort filament quantitative mass of the cellulose falls. So, as a result of reductions of the sort filament, increasing level of pollution of sample and reductions of the factor to maturity (1,8% - 1,4%) formed mass of the cellulose fell on 1,3%. Explored microstructures, chemical and physico-mechanical characteristic of 5 sorts and 9 types cotton filament. The Microscopic observations under investigation sample cotton filament have allowed to define in them amount of the growing, which number of rings decreases from 38 before to 20 with the measures of the reduction of the factor of maturity from 2,0 before to 1,2 less. Determined chemical and physico-mcchanical factors for each sort, which differ from each other on creating the different types of the cellulose i.e. alpha - celluloses (96,7% - 93,6%); beta -celluloses (2,3% -1,2%); the gamma - celluloses (2,0% -1,0%) decreases, according to increasing of degrees of pollution (2,1% -12,5%) and density (125M/teks - 200 м/teks). By means of IK, PMR - spectroscopical and x-rayscopycal analysis is studied micro- and macro structure of cotton filament of 5th sort and 9 types and two types cotton lint. The certain difference degree crystalloid cotton filament on determination of the bands of the absorption in IK - spectrum.
Practical value: theoretical and methodological rules and explanations to national Goods Nomenclature to foreign economic activity arc designed in Thesis study on categorizations goods on base of the chemical composition, can be applying at development of the national goods nomenclature. Separate its theoretical rales and explanations possible to use such scholastic discipline in process of the education as "Commodity subject", "Classification and certification of goods on base their chemical composition", "Customs expert operation", "Goods nomenclature to foreign economic activity" etc.
Degree of embed and economic effectivity: the Main results, findings and recommendations, being kept in study, offered by researcher operative methods of the realization of the customs expert operation, is accepted laboratory to State association "O’zpahtasanoat", Uzbek center on certification cotton filament "Sifat" at Cabinet Ministers of the Republic of Uzbekistan, as well as Central customs expert laboratory of the State customs committee for using in determination of the codes goods cotton filament and its product to national Goods nomenclature of foreign economic activity. The Directed offer on newly designed code goods in Committee on Harmonized System to Worldwide Customs Organization. The Separate positions of the dissertation are used in scholastic process in some educational institutions Ministry high average special formation, Tax academy of the State tax committee, Higher military customs institute. In practice it was passed the test operative methods of customs expert operation for determination of the codes goods cotton filament and its product in accordance with Goods nomenclature of foreign economic activity. On base concrete example in study is confirmed possibility of protection economic interest of republic as a result of correct categorization of the codes goods cotton filament and its product in accordance with Goods nomenclature of foreign economic activity. So, for instance, from explored sample cotton filament economic damage in amount of 370,7 mln. sum. (For December 2009).
Field of application: results of the study and theoretical findings can be applying at the State Customs Committee and laboratory agency ’’Uzstandart", them can also use the participants of foreign economic activity, specialists on customs registration, declarants and others, besides in High and average special educational institutions- in process of the education, for scientific employees - in research works.
