Dedicated machinery accessories are classifiable as parts, not refrigerating equipment, when they lack independent utility.

A refrigeration system dedicated to cooling a Chevron Baffle and usable only with the main vacuum coating unit was treated as a machinery part or accessory, not as independent refrigerating equipment. Because it had no separate utility apart from the main machine and was sold as an accessory, Heading 84.18 was held inapplicable and the residual classification under Sub-heading 8485.90 was sustained. The revenue challenge failed, and the assessee's tariff classification was upheld.

Issues: Whether the item described as a refrigeration system to cool the Chevron Baffle was classifiable under Heading 84.18 as refrigerating equipment or under Sub-heading 8485.90 as a machinery part/accessory.

Analysis: The item was found to be dedicated to the main vacuum coating unit, sold as an accessory, and lacking any independent function unless connected to the main machinery. The tariff entry for refrigerating equipment in Heading 84.18 was therefore inapplicable, while the residual heading for machinery parts not specified elsewhere in Chapter 84 appropriately covered the item.

Conclusion: The classification under Heading 84.18 was rejected and the classification under Sub-heading 8485.90 was upheld, in favour of the assessee.

Final Conclusion: The revenue appeal failed, and the assessee's tariff classification was sustained.

Ratio Decidendi: An item dedicated to and functioning only as part of a main machine, without independent utility as refrigerating equipment, is classifiable as a machinery part or accessory rather than under the heading for refrigerating equipment.
