8414 80 21 and 8414 80 29 Turbo-compressors In a turbo-compressor the vane wheel shaft is driven by an external motor and the air or the other gas to be pumped is set in motion by the vane wheel. Turbo-compressors may be single-stage or multi-stage, axial or radial. Simple two-stage compressors are used, for example, in vacuum cleaners.

8414 80 21 Single-stage This subheading also includes exhaust-gas turbochargers for internal-combustion piston engines, where they are used to compress the atmospheric air needed for combustion in order to increase power output. They are single-stage air turbo- compressors (blowers) used to generate an overpressure of more than 2 bar and are driven by an exhaust-gas turbine installed adjacent to the compressor casing. The exahust-gas turbine is supplied with exhaust gases from the internal-combustion piston engine on which it is mounted.

8414 90 10 and 8414 90 90 Parts These subheadings also include parts of exhaust-gas turbochargers for internal combustion engines. However, parts of the exhaust-gas turbine used with exhaust-gas turbochargers are classified in heading 8411 as parts of a gas turbine without combustion chamber.

8418 Refrigerators, freezers and other refrigerating or freezing equipment, electric or other; heat pumps other than air-conditioning machines of heading 8415

8418 69 99 Other This subheading includes ‘chill dryers’, which are devices used to dry the air in swimming-pool buildings and other damp premises. Basically they consist of a refrigerating unit and a motor-driven fan. The fan ingests the moist air, which is then ducted to the refrigerator-unit evaporator, where it is condensed on the cold walls. The resultant condensate water is caught in a trough. The dried air is led for reheating across the heated refrigerator-unit condenser and fed back into the room. In the case of the chill dryers used to dry compressed air in the compressed-air systems also covered by this subheading, the dried compressed air is normally reheated by means of an additionally installed air-air heat exchanger. This heat exchanger conducts the heat from the damp compressed air entering on the input side of the chill dryer via walls to the dried, compressed air. These appliances are not provided with devices for adjusting the temperature of the air. However, this subheading does not cover devices producing dry ices (slab ice) by means of the rapid reduction of the pressure of high-pressure carbon dioxide with resultant supercooling (heading 8479).

8419 Machinery, plant or laboratory equipment, whether or not electrically heated (excluding furnaces, ovens, and other equipment of heading 8514), for the treatment of materials by a process involving a change of temperature such as heating, cooking, roasting, distilling, rectifying, sterilising, pasteurising, steaming, drying, evaporating, vaporising, condensing or cooling, other than machinery or plant of a kind used for domestic purposes; instantaneous or storage water heaters, non-electric

8419 20 00 Medical, surgical or laboratory sterilisers The apparatus covered by this subheading, intended as equipment for clinics, operating theatres, medical centres, etc., consists of receptacles in which medical and surgical instruments as well as cotton wool, absorbent lint and other dressings are subjected to a temperature of 100 °C or more in order to destroy the micro-organisms they may be carrying. They are usually in the form of a paralleliped or a cylinder standing on a pedestal and containing removable grids. Generally, the container is of steel or aluminium and lined with insulating material. The door may be glazed to allow the instruments placed in the interior to be seen. Some appliances are in the form of cabinets or other furniture. In this case, a steriliser proper may incorporate a rack for storing instruments or other articles to be sterilised; this will not affect its classification in this subheading. These appliances are heated by spirit, petroleum, gas or electricity and sterilisation is effected by boiling water (vats), steam under pressure (autoclaves) or hot dry air (ovens), depending on the design of the appliance.

8419 50 10 and 8419 50 90 Heat-exchange units Heat-exchange units are used: 1. to bring about a change of temperature in fluids or gases without changing their state, this change of temperature being in some cases sufficient to cause sterilisation or pasteurisation; 2. to vaporize or condense fluids. These subheadings include: 1. condensers for nitrogen and other gases; 2. devices called ‘freezers’ for the cooling and condensing of solvents used mainly in dyeing and dry-cleaning; 3. cooling apparatus for liquids, vapour or gas, used in various industries (e.g., dairies, breweries); 4. continuous pasteurisation apparatus, used notably in dairies (plate pasteurisers). These subheadings do not cover: (a) instantaneous or storage water heaters of subheading 8419 11 00 or 8419 19 00; (b) apparatus in which: — the thermal exchange is used to transform a liquid or gaseous substance into a solid state (for example, spray drying); — the thermal exchange between the two fluids does not take place through a wall (for example, a free air-flow tower). Such apparatus is generally classified in subheading 8419 89 10 or 8419 89 98.

8419 89 10 Cooling towers and similar plant for direct cooling (without a separating wall) by means of recirculated water This subheading covers cooling towers in which the water to be cooled releases its heat directly into the air by means of evaporation. The heated water is pumped up, then trickles down freely inside the cooling tower and in so doing is cooled by the rising air (chimney effect).

8419 89 98 Other This subheading covers apparatus for smoking raw sausages, even when the sausage undergoes a thermal treatment during smoking, which results in the partial or total cooking of the sausage. They consist of a large chamber heated by steam coils; hot or cold smoke is blown into the chamber from outside by a fan. They are equipped with a humidifying installation and coils containing cold water for cooling. The raw sausages are conveyed into the chamber suspended on moving frames. Items of equipment known as ‘tableware dispensers’ for the holding and dispensing of tableware to diners in canteens or self-service restaruants are excluded from this subheading, even where they are equipped with an electrical heating device or water bath heating for warming the tableware (heading 9403).

8421 Centrifuges, including centrifugal dryers; filtering or purifying machinery and apparatus, for liquids or gases

8421 39 71 By a catalytic process This subheading includes catalytic exhaust gas purifiers for fitting in the exhaust systems of motor vehicles or in flue gas lines of industrial plant, to remove the nitrogen oxide and, possibly, other pollutants (e.g., carbon monoxide and hydrocarbons) from the exhaust or flue gases by means of a chemical reaction in order to reduce air pollution. Catalytic converters fitted in motor vehicles consist of a housing containing a ceramic honeycomb (monolithic support) composed of channels coated with activated catalytic material. In industrial plant, flue gas purifiers consist of a support frame containing a large number of catalytic components. Monolithic supports and catalytic components presented separately, however, are classified as catalysts in heading 3815.

8423 30 00 Constant weight scales and scales for discharging a predetermined weight of material into a bag or container, including hopper scales This subheading includes electromechanical scales of the type described above. The design and method of operation of these scales correspond to those of the electromechanical scales described in the Explanatory Notes to subheadings 8423 81 10 to 8423 89 00.

8423 81 10 to 8423 89 00 Other weighing machinery These subheadings include electromechanical scales in which the weight of objects is converted into an electrical signal (current) by means of a transducer fitted into the scales, the current then being measured by a measuring device incorporated in the scales. As a rule the measuring transducers in such scales consist of load cells or bars with strain gauges (electrical resistances) connected to form an electrical bridge. The force exerted by the mass to be weighed deforms the load cells, causing a change in the length of the strain gauge (contraction or elongation) and thus a change of resistance which is proportional to the mass to be weighed and which is passed in the form of a change of current to the measuring device on the scale by the reistance measuring bridge. In addition to the measuring instrument, known as a weighing-out unit, scale display or weighing indicator, which is normally contained in a single casing, electromechanical scales can also have other units which are wired up together (e.g., keyboard, memory unit, printer, VDU, controller and card reader for controlling access to the scales). In weighing systems of this kind several scales may be connected to a common measuring instrument (also known as ‘remote weighing terminals’). The above scales may also be equipped with an interface through which the scales can be connected to an automatic data-processing unit. Electromechanical scales are considered to be ‘electronic scales’ if microprocessors are built into the scales' measuring instrument, for example, in order to calculate the cost of the amount weighed using the unit price (e.g., price per kilogram) entered into the scale.

8424 Mechanical appliances (whether or not hand-operated) for projecting, dispersing or spraying liquids or powders; fire extinguishers, whether or not charged; spray guns and similar appliances; steam or sandblasting machines and similar jet projecting machines

These subheadings cover sewing machines and sewing machine heads having both the following characteristics: (a) they must be lock-stitch only (running-stitch, zig-zag stitch, decorative stitch), i.e., operate with two threads, one inserted on the needle and one carried underneath by a shuttle; (b) the head must not exceed 16 kg in weight without motor or 17 kg, including the motor (in the case of an incomplete head to be classified as complete in accordance with General Interpretative Rule 2 (a) of the Combined Nomenclature, it is the weight in the complete state which counts). 2. The sewing machine head comprises the working unit of the machine (including, where relevant, the motor incorporated in or mounted on the head) and consists essentially of an arm containing the needle-driving mechanism and a base containing the shuttle mechanism and possibly a device for lifting the presser foot. The frame, table, cover and other furniture (including the pedal board) do not form part of the head. 3. It should be noted, however, that on some portable sewing machines the base is designed to serve also as a stand. In this case, it is regarded as a sewing machine and not as a sewing machine head.

8452 30 10 With single flat shank These needles are used in household sewing machines. They have the following appearance:

8456 Machine tools for working any material by removal of material, by laser or other light or photon beam, ultrasonic, electrodischarge, electrochemical, electron beam, ionic-beam or plasma arc processes

8456 10 90 Other In addition to the machines referred to in the HS Explanatory Notes to heading 8456, (A), this subheading also includes machines for trimming electrical resistors in printed circuits using a laser beam. The conductive material which constitutes the resistors on the insulating substrate of the printed circuits is removed by means of a laster beam until the desired resistance is attained.

8456 30 11 Wire-cut These machines are equipped with an electrode which consists of a small diameter wire which is wound between two spools set on opposite sides of the workpiece.

8456 91 00 For dry-etching patterns on semiconductor materials This subheading includes plasma-etching machines which use a plasma beam to etch structures in the semiconductor material of wafers. These automatic, microprocessor-controlled machines essentially consist of a process chamber with an anode and a cathode, a high-frequency generator, vacuum pumps, a gas supply line and a feeder device for transporting the wafers. The wafers are fed into the evacuated process chamber in which an electric current has been generated between the anode and cathode by the high-frequency generator. In the gas atmosphere of the process chamber an electric discharge produces positively-charged gas ions which collide with the wafer (the cathode), removing material from it by virtue of their impact energy. See the HS Explanatory Notes to subheading 8456 91.

8457 Machining centres, unit construction machines (single station) and multi-station transfer machines, for working metal

8457 10 10 Horizontal This subheading covers machining centres where the tooling is exclusively set in a horizontal spindle and cuts the workpiece from the side.

8457 10 90 Other This subheading includes machining centres where the tooling is applied to the workpiece from above (vertical spindle machining centres), those using both vertical and horizontal spindles (combined machining centres) or those working through the use of a pivoting head (universal machining centres).

8458 Lathes (including turning centres) for removing metal This heading covers lathes specially designed for working metals and which operate by removing the material with the help of turning tools. In general, the article to be shaped is driven in a rotary movement around its own axis. However, lathes in which the tool itself or the tool and the article are rotated are also covered by this heading. In addition to the lathes referred to in the HS Explanatory Notes to heading 8458, third paragraph, this heading includes special relieving lathes for axles, bark-stripping lathes and spindle or axle turning machines, as well as universal lathes. These universal lathes resemble slide lathes but are differentiated by a particular mechanism which enables them to perform other functions such as drilling, milling and cutting into lengths, in addition to turning.

These machines are equipped with measuring or setting devices. These devices include: 1. direct reading linear instruments, for example, slide rules and verniers, on which the space between two successive graduations corresponds to a movement of an element of the machine not exceeding 1/100th mm (0,01 mm); 2. profile projectors for checking work in progress. These projectors consist of a graduated ground-glass screen on which a greatly enlarged image of the article and tool is projected so that any travel of the article or tool, as well as the progress of the working process, can be assessed by reference to the graduations on the screen. The work can also be checked by placing on the screen a drawing of the article to be obtained traced on a transparent sheet on a scale corresponding to the magnification factor of the profile projectors; in this case, the machine operator's task is to make the image on the article coincide with the drawing seen on the screen; 3. devices limiting the travel of the tool holder or workpiece holder by means of an adjustable device whose positioning is controlled by means of a slip gauge; 4. electronic checking and control devices for honing and lapping machines which are adjusted by means of a graduated scale on the actual final dimensions of the article and which allow the tool to be slowed down and stopped when the dimensions of the article approach and attain the previously determined dimensions.

8460 21 11 to 8460 29 90 Other grinding machines, in which the positioning in any one axis can be set up to an accuracy of at least 0,01 mm See the Explanatory Notes to subheadings 8460 11 00 and 8460 19 00.

8460 21 11 Internal cylindrical grinding machines Internal cylindrical grinding machines are used for grinding internal diameters of hollow workpieces (e.g., the bore). The workpiece is held in a chuck and worked with a grinding wheel small enough to enter the hollow bore of the workpiece.

8460 21 15 Centreless grinding machines Centreless grinding machines are used for grinding the external diameters of workpieces. In the centreless process, the workpiece is not fixed but rests on a rail between the rotating grinding disc and a guide disc (also driven). The diameter required is determined by the distance between the grinding disc and the guide disc.

8460 21 19 Other This subheading includes universal grinding machines. These are a combination of external and internal grinding machines and can therefore work simultaneously on both the external and internal diameters of a workpiece.

8460 29 11 Internal cylindrical grinding machines The Explanatory Notes to subheading 8460 21 11 apply, mutatis mutandis.

8460 29 19 Other The Explanatory Notes to subheadings 8460 21 15 and 8460 21 19 apply, mutatis mutandis.

8461 30 10 and 8461 30 90 Broaching machines These subheadings cover broaching machines (see the HS Explanatory Notes to heading 8461, third paragraph, (4)); these are machine tools consisting of a multiple-tooth cutting tool, called a broach, used for working the interior or exterior surfaces of an article. In these machines, the article is fixed and the broach, secured to the slide, is pulled or pushed across the work piece in an even, linear cutting motion. The internal broach works and calibrates the internal surfaces of a rough or pre-worked article traversed by the tool. The external broach produces plane or profile surfaces.

8461 40 11 and 8461 40 19 For cutting cylindrical gears Only gears which are obtained from cylindrical blanks and which retain that form after cutting are considered as cylindrical gears for the purposes of these subheadings.
