B The numerous types of machines falling in the heading include the following : (1) Spring balances. (2) Household or shop scales. (3) Letter or parcel scales. (4) Personal weighmg machines (coin operated or not), including baby scales. (5) Portable or mobile platform type scales. (6) Weighbridges (hydraulic or other) and other weighing platforms. (7) Scales for weighing goods on conveyor bands, overhead conveyors, etc. (8) Weight operated counting scales. (9) Constant weight scales such as check scales (indicating excess or deficient over standard weight) and continuous weighers for checking the uniformity of textile or otxer materials. (10) Hopper scales, for automatically weighing materials discharged from hoppers, including those weighing ingredients fiom several hoppers in compoundmg a mixture. (11) Scales for discharging a predetermined weight of material into a ba or container, but not including such machines which also ack or wrap the goods in the o m or presentations in which they are normally distribute and sold in commerce. (12) Automatic balances for weighing a continuous flow of liquid. (13) Apparatus full automatic, which weighs and labels repacked goods, comprisin weighng, mac ine, a calculator and a printer with bui t-in package totaliser and la el ejector. K %" P These various weighing machines may inco orate provision for automatical~yprinting weight tickets, for recording and totalling a series o weighing operations, for p~ojectmgor magtllfjmg the reading, etc. ?' The heading also covers weights of all kinds and of any material, whether or not in sets or cases, for any type of weighin machine, includin se arately presented weights for recision machines of heading 90. 6; wei hts presentej wig such precision machines are, owever, classified therewith. Cursor wei$ts (mncluding those of p atinurn) are also covered by this heading. f PARTS General Sub'ect to the general provisions regarding the classification of parts (see Exp anatory Note to Section XVI), the heading includes parts for the weighing machrnes of this heading. Such pasts include : Scale beams, calibrated or not; scale pans and platforms; base- lates, supports and casings; knife-edges, pivots and pivot bearings (exce t those wholly o a ate or other precious or semi-precious stones (heading 71.16)); hy aulic dash-pots (osci lation dampers); weight indicator dials. The heading does not cover : (a) Hydrostatic (or specific gravity) balances (heading 90.16). (b) Machines for balancing mechanical parts (heading 90.31). (c) Instruments such as dynamometers of a kind primarily designed for measuring tractive, compressive forces, etc., and not for weighing goods, persons, animals, etc. (heading 90.24 or 90.31).

Subheading Explanatory Note. Subheading 8423.20 The scales for continuous weighing of goods on conveyors of this subheading, which may be either of the totaliser or integrating kind, measure and record the weight of materials as they go past in buckets, on chains or the like.
