Republic of  Uzbekistan is the state of production of cotton fiber, occupies fifth-sixth place in the world production of cotton fiber   and second place after USA on export. Cotton fiber and its production are the main strategic goods of the Republic. At conversion of cotton is possible to get the cotton filament, waste cotton plant, waste of textile industry, cotton lint, cotton, cotton wool and many other wastes. The problems appear at the export of these mentioned products on classification of goods, on the goods nomenclature of Foreign Economic Activity of the Republic Uzbekistan.

It’s known that below enumerated countries produce the cotton filament and products: USA, Mexico, Brasilia, Turkey, Australia, Syria, Egypt, Pakistan, India, Uzbekistan, Tadzhikistan, Turkmen and others. Installed, that Uzbek filament at present on consumer characteristics don’t yield, but on some features the quality of  cotton filament exceed among the most largest countries as USA, India, China.

In Republic happened to solve the difficult problems on deduction and further fortification position of Uzbek cotton fiber on the world market. The Efforts of government of the Republic were directed on reformation and improvement of whole cotton branch, commencing from removing of new selection sorts of the cotton plant and finishing efficient policy of the marketing filament in accordance with modern market mechanism.

The Background element of the policy of government on increasing of competitiveness filament was support        by Ministry of rural and water facilities and selectors of the republic, which in these years undertook the row of the drastic measures on improvement of the high-quality composition of the cotton plant, removing new early-ripening, higher harvest, firm to diseases and vermin sorts with high quality and share of the output filament, as well as preparation of  material for undertaking efficient relief sort[1].

From literature is known for quality analysis of cotton filament are used different modern methods of the analysis and instruments. We give some examples typical for all countries, growing cotton. The measurements of the qualitative features are executed by exact speediest methods, which usually is identified "Classification HVI".

Test the cotton began in 1920, but velocity of the acceptance noticeably increased from the time at which USA have altered by sawing to 100% test filament on system HVI at the beginning of 1990. During undertaking 61 plenary sessions in Cairo in 2002 representatives of the producers and users came to the total opinion about that cotton industry necessary to move onward on way to taking the systems of the estimation quality filament, founded on instrument, but on 62 plenary sessions in 2003 in Gdansk they have came to a conclusion that for standardization of test results  necessary international agreement on use the systems of the estimation quality of cotton by means of instrument.

 Beside one on third world production of cotton fiber is at present checked at a rate of producer instrumentally, and this percent grows. We suppose that at the following five years more then half of the cotton production in the world will be valued with using of the systems HVI. The Large powered instrument HVI – higher automated module system for measurement and determined physical features of the textile filaments and, in the first place of cotton filament.

World cotton industry developed more than two ages in the manner of independent national industry often on local rules and trade procedures, units of the measurement and internal standard quality. The size of the stacks and their density differed in miscellaneous countries. China releases stacks both on 80 kgs, and on 225 kg. The rate of the weight in South Asia are on stacks 170 kgs, 400 pounds - in West Africa, 480 pounds of the stack are accepted in USA, 227 kgs stacks in Australia and 720 pounds of the stack in Egypt. The standards of quality differ in miscellaneous countries, including universal cotton standards and multiple national standards, supported national organization in many cottons-sow countries. Some countries have qualitative parameters, founded on numeral, which unite the color, texture and litter in one category, others use the letters. In some countries qualitative standards are differentiated on sorts, in the other countries distinguish the cotton and saw and topple dginirovaniye. The different standards quality do not find the concordant correlation, allowing produce the exact comparison of different sorts of cotton and its production.

The Cotton plant, as live plant, with its acclimatization, sorts, increasing its fibers, oily, moisture nutriment, speedup of the periods of ripple, with reference to different light weather forecast condition, research many scientists -biologists, chemists, physicists in all country of the world growing cotton.  Cotton plant, as the most important technical plant, has not exhausted their own possibilities, but, on the contrary, shows their own new, inimitable working quality. In light of the foregoing considerations, at determination of the goods code of cotton filament necessary to take into account the latest achievements of the science in the field of breeding and creation of its early-ripening sorts, economy watered resources, as natural polymer, residing in unceasing biological renovation and improvement.

In one pound of the cotton fiber can be kept till 100 and more millions of the filaments.  Each filament is an offshoot from separate hutch, which develops on surface layer of the cottonseed. On early stage of its development filament lengthens on get fat length as pipe with fine wall. On measure of the maturation wall filament is thickened to account of the postponing the cellulose, leaving cavity in the centre. When period of the growing ends and alive material dies, filament decays and  twisted around its own axis.    

From literature is known that filament by length 29-32 mm in China and Republic of  Korea are used for reception of fabrics i.e. in textile production. In Republic Uzbekistan, according to GUST  the most short filaments is equal to 29,2 mm so on the world market Uzbek cotton filament is considered popular for production fabrics.

As a result of complex study of physic-chemical and mechanical characteristic of goods filament was proved by us need to its classification of cotton filament and its products on Goods nomenclature of foreign economic activity. Herewith necessary to come from such parameter, as length filament, mass share vice and rubbish admixtures, linear density, moisture, factor to maturity, molecular mass, viscosity solution and etc. In requirement international standard as main parameter of cotton fiber is accepted its length. In other words, there is practicability and need to provide in correspondence to with requirements of international standard applicable in practice state standards and standard specifications on cotton filament and its different marketable products. Us are designed methods of the determination of the new goods codes for cotton filament and its product on the base of their chemical composition, legally protecting economic interests of the Republic.

During the firs time of research work was investigate sorts of miscellaneous cotton filament, but cellulose is chosen on the known method. Studied the leaving the cellulose from miscellaneous sort filament.

In the Republic Uzbekistan, Tadzhikistan and Turkmen is used Goods nomenclature of foreign economic activity Eurasian Economic Community (EVRAZES) i.e. 10 signs codes of goods.

At classification of cotton fiber and its derived on Goods nomenclature of foreign economic activity appears the certain difficulties. In this connection was studied composition, physical chemical factors of cotton in accordance with requirements O`z DSt.

In the first place was researched code numbers of cotton filament and its product on Goods nomenclature: cotton filament (the goods position 5201), product after conversion cotton filament (the goods position 5202), product, formed after conversion of the cotton-product in its raw state (ulyuk, carbon-monoxide fumes); (the goods position 5202) product, formed after conversion cotton filament on textile production (ulyuk, carbon-monoxide fumes, Standard 1-17).  The product for instance "wastes", forming after conversion of cotton filament on textile production, length filament is equal from 5 till 29,2 mm, is  valuable raw material for reception of the net cellulose.

2 types of cotton filament exist in according to O`zDSt of the Republic of Uzbekistan: middle fiber and long fiber, from them 5 sorts, 9 types, which differs from each other on physical-chemical parameters, on length as follows, exterior, moisture, wastes and others, to which are used codes of the Goods nomenclature of Foreign economic activity and which are classified on two goods positions: 520100100 - - - hygroscopic or bleached, 520100900 - - - others.  So, on our opinion, at classification of cotton filament on Goods nomenclature of Foreign economic activity as main criterion reasonable to take the length a filament so necessary to carry in subheading 5201000100 additional code numbers 10 and 11.
