Case Note & Summary
The appeal before the Supreme Court concerned the correct customs tariff classification of imported components and accessories for manufacturing volumetric displacement type flow meters. The appellant was a manufacturer of such flow meters and imported goods described in the bill of lading as 'Industrial Metric Equipment (component and accessory Volumetric Type Flow Meter)'. The flow meter consisted of a measuring device, a control device, a starting/stopping device, and an action device. Purchase orders from public sector oil companies described the equipment as double case type flow meters with accessories and single case rotary vane positive displacement meter with large numeral counter, rate of flow indicator, strainer-cum-air eliminator. The Assistant Collector of Customs found that the meter produced by the appellant was capable of showing the rate of flow but, since it was also used for measuring volume, classified it under Tariff Heading 90.26 by relying on clause (c) of the General Rules for Interpretation of the First Schedule - Import Tariff. The Collector (Appeals) and the Tribunal affirmed this classification. The relevant tariff entries were Heading 90.24 for instruments and apparatus for measuring, checking or automatically controlling the flow, depth, pressure or other variables of liquids or gases, which specifically included flow meters; Heading 90.26 for gas, liquid and electricity supply or production meters and calibrating meters; and Heading 90.29 for parts or accessories suitable for use solely or principally with one or more of the articles falling within Headings 90.23, 90.24, 90.26, 90.27 or 90.28. The Court observed that flow meters were specifically covered in Heading 90.24 and that the principle 'specific excludes general' applied. Heading 90.29 permitted levy on parts or accessories used solely in the manufacture of articles falling within Heading 90.24. The Assistant Collector had found that the imported accessories were used solely for the meter manufactured by the appellant, and if the meter satisfied Heading 90.24 then by virtue of Heading 90.29 the components would attract duty at the same rate. The legal issue was whether the classification changed by application of the Interpretative Rules. The Rules were framed on the Brussels Convention to ensure uniform classification in world trade. Rule 2(b) referred to Rule 3 for goods consisting of more than one material. Rule 3(a) preferred the most specific description; Rule 3(b) applied where classification could not be by (a); and Rule 3(c) was residuary, applying only if neither (a) nor (b) applied. The Court held that the classes were mutually exclusive. The primary question was whether the goods fell under clause (a). Clause (a) embodied the principle that specific heading must be preferred over general heading. The item manufactured by the appellant was described and used as a flow meter, specifically classified under Heading 90.24, while Heading 90.26 was general in nature, applying to every production or calibrating meter for gas, liquid and electricity supply. On the findings recorded, the goods specifically fell under 90.24, though they might also fall under 90.26. Preference should be given to 90.24 as the most specific. The Tribunal had applied clause (c) and levied duty under 90.26 as it was a later heading, but clause (c) applied only if clauses (a) and (b) did not. Since the goods satisfied the specific description of 90.24, the Tribunal erred. The Supreme Court allowed the appeal and held that the imported items, being component parts of the flow meter, were classifiable for payment of duty under Tariff Heading 90.24.
Headnote
A) Customs Law - Tariff Classification - Specific Heading Prevails Over General Heading - Customs Act, 1962, First Schedule General Rules for Interpretation Rule 3(a) - Imported components and accessories of a volumetric displacement type flow meter were classifiable under Tariff Heading 90.24 because flow meters are specifically covered there, whereas Heading 90.26 was a general entry for gas, liquid and electricity supply or production meters. The Court reasoned that the specific heading must be preferred over the general heading under Rule 3(a). Held that the goods satisfied the most specific description of being a flow meter and were therefore classifiable under Heading 90.24 (Paras 2-3). B) Customs Law - Application of Residual Classification Rule - Rule 3(c) Applies Only When Rules 3(a) and 3(b) Do Not Apply - Customs Act, 1962, First Schedule General Rules for Interpretation Rule 3(c) - The Tribunal applied clause (c) and levied duty under Heading 90.26 because it was a latter heading numerically. The Court held that clause (c) is residuary in nature and could not be invoked when the goods fell squarely under the specific description in Rule 3(a). Held that the Tribunal committed an error of law in classifying the goods under Heading 90.26 by applying Rule 3(c) (Paras 2-3). C) Customs Law - Parts and Accessories Classification - Duty on Components Solely Used with Flow Meters Follows End-Product Heading - Customs Act, 1962, First Schedule Heading 90.29 - Heading 90.29 covers parts or accessories suitable for use solely or principally with articles falling within Heading 90.24. Since the imported components were solely used in the manufacture of the appellant's flow meter, and the flow meter fell under Heading 90.24, the components were liable to be classified at the same rate as the flow meter. Held that the imported items being component parts of the flow meter were classifiable for payment of duty under Tariff Heading 90.24 (Paras 2-3).
Issue of Consideration
Whether imported components and accessories of a volumetric displacement type flow meter should be classified under Tariff Heading 90.24 (specific for flow meters) or Tariff Heading 90.26 (general for gas, liquid and electricity supply or production meters), and whether Rule 3(c) of the General Rules for Interpretation of the First Schedule was wrongly applied by the Tribunal.
Final Decision
The appeal succeeded and was allowed. The imported items which are component parts of the flow meter shall be classified for purposes of payment of duty under Tariff Heading 90.24.
Law Points
- specific heading prevails over general heading
- Rule 3(a) of General Rules for Interpretation of the First Schedule
- Rule 3(c) is residuary and applies only when Rules 3(a) and 3(b) do not apply
- Heading 90.29 covers parts and accessories used solely with flow meters
- flow meters are specifically covered under Heading 90.24
- Interpretative Rules framed on Brussels Convention ensure uniform classification
