Substantial expansion for customs benefit requires proof of increased installed capacity, not merely modernisation or higher efficiency.

Entitlement to assessment under Heading 98.01 depended on proof of substantial expansion of the existing newspaper unit, which required an increase in installed capacity of at least 25%. The imported portable picture transmitters, automatic picture receiver and allied equipment improved printing speed and production efficiency, but no evidence showed any increase in installed capacity. Modernisation, renovation, or better efficiency was treated as insufficient to satisfy the statutory condition for the customs benefit, so the claimed assessment concession was unavailable.

Issues: Whether import of portable picture transmitters, automatic picture receiver and allied equipment for a newspaper unit entitled the appellants to assessment under Heading 98.01 on the basis of substantial expansion.

Analysis: The benefit under the relevant notification depended on proof that the existing unit had undergone substantial expansion, which in turn required an increase of installed capacity by not less than 25%. The imported equipment was found to modernise the printing process and improve speed, but no material was produced to show any increase in installed capacity. Increase in production efficiency was held not to be the same as increase in installed capacity, and modernisation or renovation of an existing unit was held insufficient to satisfy the condition for the claimed assessment benefit.

Conclusion: The claim for assessment under Heading 98.01 was rejected and the benefit of the notification was held unavailable to the appellants.

Final Conclusion: The appeal failed because the imported equipment did not establish substantial expansion of the existing unit for customs assessment purposes.

Ratio Decidendi: For entitlement to the claimed customs benefit, the assessee must prove an actual increase in installed capacity to the prescribed extent; mere modernisation or improvement in production efficiency does not amount to substantial expansion.
