classifiable under the heading 8529. Since the Radar Cables, Radar Antenna and Radar Processor are parts/ components of the complete radar system, and they are assembled to form the Radar, the Radar Antenna and Radar Processor are specifically classified under Customs Tariff Heading (CTH) 85299090 and all types of coaxial cables find classification under Chapter Heading 8544 therefore, Radar Cables are correctly classifiable under Customs Tariff Heading (CTH) 85442090. Learned AR also drew our attention to the relevant Chapter Hearding 8526 as applicable to radar and submits that the Adjudication Authority adopted the classification after considering the Chapter Note and respective Tariff Entries and General Rules of Interpretation. Further as regards the submission made by appellant regarding Section Note 3, Learned AR submits that under Section Note 3, parts and accessories which are not suitable for use solely or principally with the articles of Chapters 86 to 88 are excluded from those Chapters. The effect of Note 3 is therefore that when a part or accessory can fall in one or more other Sections as well as in Section XVII, its final classification is determined by its principal use. Thus, the steering gear, braking systems, road wheels, mudguards, etc., used on many of the mobile machines falling in Chapter 84, are virtually identical with those used on the lorries of Chapter 87 and since their principal use is with lorries, such parts and accessories are classified in this Section. Further when parts and accessories classifiable in two or more headings of the Section, certain parts and accessories are suitable for use on more than one type of vehicle (motor cars, aircraft, motorcycles, etc.); examples of such goods include brakes, steering systems, wheels, axles, etc. Such parts and accessories are to be classified in the heading relating to the parts and accessories of the vehicles with which they are principally used.
