Hand-operated mechanical apparatus for dispensing a liquid into a container for titrimetric analyses (so-called ‘digital titrator’). The apparatus comprises an adjustable mechanical feeder with a space for a cartridge, a delivery knob, a mechanical counter, a counter reset knob and a hand grip. The titrator is a precision dispensing apparatus which, by each turning step of the delivery knob, releases a drop of the titrant being used into the liquid to be analysed (the analyte). The drop contains
Classification is determined by General Rules 1 and 6 for the interpretation of the Combined Nomenclature and by the wording of CN codes 8479, 8479 89 and 8479 89 97. As the apparatus does not continuously displace volumes of liquid, classification as a pump under heading 8413 is excluded. The apparatus does not perform a chemical analysis of the titrant or the analyte. Therefore, classification as apparatus for chemical analysis under heading 9027 is excluded. Even though the apparatus contributes to the process of a chemical analysis, it cannot be considered as a part or an accessory of such apparatus by virtue of Note 2(a) to Chapter 90. The apparatus is not used to measure in volumetric units the amount of fluid passing through a pipe. Therefore, classification as an apparatus under heading 9028 is excluded. The apparatus counts the number of drops but does not measure the quantity dispensed. Therefore, classification as an apparatus under heading 9031 is excluded. As the apparatus not only counts a total number of units (drops) but primarily distributes a specific volume of liquid, it functions as a burette with a mechanical counter. It is therefore to be classified under CN code 8479 89 97 as other mechanical appliances having individual functions, not specified or included elsewhere in Chapter 84. Documented CN 2026 code: 84798997.
