84.34 Milking machines and dairy machinery. 8434.10 - Milking machines 8434.20 - Dairy machinery 8434.90 - Parts This heading covers mechanical milking machines, and other machinery, whether for farm or industrial purposes, used in the treatment of milk or for converting it into other dairy products. (I) MILKING MACHINES A milkin machine com rises a cluster of teat-cups (each with a rubber liner) which are connecte by means of exible tubing, on one side to a vacuum pum unit via a pulsator and on the other to a milk pail (usually of stainless metal). The pulsator, w ich is fixed to the lid of the milk pail, acts on the teat-cups by alternating atmospheric pressure with a comparative vacuum between the cu s and the liners. The assembly formed by the teat-cup cluster, the pulsator and the milk pai is described as a " milking pail ". b: R R P In certain machines of smaller capacity, the milking pails and the vacuum pump unit may be on a common base (single or twin-pail machines). In the machines of necessary directly to the teats of the cow. of such machines are classified in this meaning of Note 4 to Section XVI (see the apparatus and appliances which do not devices, storage tanks, a paratus for in this heading ut in their f 01) MACHINES FOR PROCESSING MlLK This oup includes homo enisers. These break up the fat into fine particles which are more readi y digestible, and whick, also remain longer in a state of emulsion without the formation of cream. F The majority of machines for processing milk depend essentially on the principle of heat exchange and are therefore excluded (heading 84.19), e. ., apparatus far pasteurisation, stassanisation or sterilisation; apparatus for condensing or drying milk; mifk coolers. The heading further excludes : (a) Refrigerating a pliances (whether or not speciaIly designed for cooling or keeping milk) and milk-cooling vars, incorporating an evaporator of a refrigeratingunit (heading 84.18). (b) Cream se arators, filter- resses and other filtering or clarifyxng machinery or apparatus (Simple 8lter funnels and milk strainers are, however, classified according to the (heading h.21). constituent material.) (c) Machines for washing milk containers, and milk bottling or canning machines (heading 84.22). (III) MACHINERY FOR CONVERTING MILK INTO OTHER DAIRY PRODUCTS It should be noted that cream separators are excluded (heading 84.21). The heading does, however, cover machines, used for the manufacture of butter or cheese. They include : (A) Butter-making machines. (1) Churns usual1 consist of a barrel of stainless steeI, inside of which are a number of partitions or b ades. The barrel or the blades are rotated by motor power and the resultant beating action hardens the cream to foam and gradually converts it into butter. (2) Combined churns and workers. These machines, which are used for continuous production of butter, consist essentially of electric motors that drive cylinders with fast rotating elements which transform the cream into butter. The butter is pressed through the working elements of the machine as a continuous length. (3) Machines for mouldin butter into the required commercial sha es, but not including machines whic also wrap or weigh the product (headings 84. 2 and 84.23). E @) Cheese-making machines. (1) Machines for breaking up and homogenising the mixtures of curd and cream in the manufacture of soft or cream cheeses. (2) Machines for moulding hard, semi-hard and soft or cream cheeses, but not including machines which also wrap or weigh the product (headings 84.22 and 84.23). (3) Cheese presses (e. ., of the mechanical, pneumatic, etc., types) are used, especially in the manufacture o harder cheeses, both to shape the product and to eliminate the superfluous moisture. f It should be noted that the heading excludes many machines and apparatus used in the dairy industry. For example, storage, maturing, processing, etc., vats and tanks whose operation depends primarily on fitted heating or cooling equipment fall in heading 84.18 or 84.19, whether or not they also incorporate mechanical equipment such as agitators. Vats, etc., not fitted with heating or cooling equipment, but incorporating mechanical features such as stirrers, a itators, tipping mechanisms, etc., are classified in this head~n provided they are identifiable as specialize for dairy use. If the are not identifiable as for any one Particukar use, they are classified in beading 84.79. Vats, etc., not fittedywith either thermal or mechanical equipment are classified as articles of the constituent material (e.g., heading 73.09, 73.10, 74.19, 76.11, or 76.12). d PARTS Sub'ect to the general provisions regarding the classification of parts (see the General Exp anatory Note to Section XVI), parts of the machines of this heading are also classified here, e.g. : f Pails, lids, pulsators, teat-cups and fittings (other than rubber liners, etc. - headin 40.16) for milking machines; butter churn barrels; rollers and tables for butter workers; moul s for butter and cheese moulding machines. f The heading excludes domestic appliances falling in beading 82.10 or 85.09.

Other steel balls are to be classified in heading 73.26. 8.- A machine which is used for more than one purpose is, for the purposes of classification, to be treated as if its principal purpose were its sole purpose. Subject to Note 2 to this Chapter and Note 3 to Section XVI, a machine the principal purpose of which is not described in any heading or for which no one purpose is the principal purpose is, unless the context otherwise requires, to be classified in heading 84.79. Heading 84.79 also covers machines for making rope or cable (for example, stranding, twisting or cabling machines) from metal wire, textile yarn or any other material or from a combination of such materials. 9.- For the purposes of heading 84.70, the term “pocket-size” applies only to machines the dimensions of which do not exceed 170 mm x 100 mm x 45 mm. 10.- For the purposes of heading 84.85, the expression “additive manufacturing” (also referred to as 3D printing) means the formation of physical objects, based on a digital model, by the successive addition and layering, and consolidation and solidification, of material (for example, metal, plastics or ceramics).
