Transaction value of liquid chlorine excludes optional hydraulic testing charges for customers' tonners lacking nexus with sale value.

Hydraulic testing charges collected for customers' tonners were held outside the assessable value of liquid chlorine because the testing was optional, undertaken only at the customer's request, and related to the containers rather than to the sale or value of the chlorine. The article notes that liquid chlorine was marketable as such and was supplied in the assessee's own tonners, customers' tonners, and sometimes through pipeline, so the testing activity did not form part of the transaction value. Only amounts having a direct nexus with the sale of the excisable goods and contributing to their value can be included under Section 4 of the Central Excise Act, 1944.

Issues: Whether hydraulic testing charges collected for customers' tonners in which liquid chlorine was supplied were includible in the assessable value of liquid chlorine under the transaction value mechanism.

Analysis: The liquid chlorine was found to be marketable as such and was sold not only in the assessee's own tonners but also in customers' tonners and, in some cases, through pipeline. The testing of customers' tonners was optional, undertaken only on the customer's request when the tonners were due for testing under the Gas Cylinder Rules, 1981. The charges related to a separate activity concerning the customers' containers and did not contribute to the value of the chlorine or arise in connection with its sale. The principle applied was that only amounts having a nexus with the sale and contributing to the value of the excisable goods can form part of transaction value.

Conclusion: The hydraulic testing charges were not includible in the assessable value of liquid chlorine and the Revenue's appeal failed.

Ratio Decidendi: Amounts collected for an optional activity relating to customers' containers, where the goods are otherwise marketable and the activity has no nexus with the sale or value of the goods, are not includible in transaction value under Section 4 of the Central Excise Act, 1944.
