Full Judgment
2. Heading 85.26 reads: "Radar apparatus, radio navigational aid apparatus, radio remote control apparatus". The heading comprises two sub-headings. Subheading 8526.90 is for radio apparatus, 8526.91 for radio navigational aid apparatus and 8526.92 for radio remote control apparatus. This heading and the subheadings in the Customs Tariff are identical in terminology with the heading and sub-heading in the HSN Explanatory Notes. Reference to notes is hence justified in determining the scope and applicability of the headings and sub-headings. The explanatory notes Second Edition (1996) specify twelve types of apparatus or equipments as being included in this heading. Will the existence of radar height measuring apparatus (radio altimeters) these goods are, essentially radar equipment simpliciter employing the principle of radar either to locate the position of the aircraft or ship or identify buoys, beacons or aircraft or to measure the height of aircraft or other similar objects.
3. A reading of the explanatory notes makes it clear that mere employment of radar in an equipment or apparatus is not enough to justify classification of that equipment or apparatus in this heading.
Thus while radar devices in proximity fuses or bombs are classifiable under this heading the notes specify complete fuses with their detonators as falling under heading 93.06. Similarly special purpose vehicles permanently equipped with radar or other apparatus of this heading are excluded from the heading. It would therefore be reasonable to conclude that equipment in which radar is used as an aid or tool for the performance of the specific function would be classified, not as a radar apparatus, but by reference to the function for which the radar is employed. Applying that principle, it would follow that the goods in question which are specifically designed for measuring the level of liquids rightly classifiable under heading 90.26. This is also made clear by the explanatory notes for that heading at page 1636 indicating level indicators for liquids functioning on ultrasound, to be classifiable under heading 90.26.
4. The Commissioner has not considered these aspects in coming to the conclusion. He has been exclusively guided by the fact that the radar is employed in the equipment. His reasoning, which was adopted by the departmental representative is not acceptable in view of our earlier discussions. The goods merit classification under heading 90.26 which is also more specific in scope.
