Conditional customs exemption allows late certificate compliance and treats an imported catalyst as raw material in manufacture.

A conditional customs exemption was analysed on two points: first, where the notification required a supporting certificate but prescribed no time limit, late production of the certificate at the appellate stage was treated as substantial compliance and did not by itself defeat concessional duty; second, an imported catalyst used in a fertiliser plant was held to fall within "raw materials" for the notification because eligibility turned on its functional role in manufacture, even though it did not remain in the finished product. The commentary concludes that such exemption conditions may be satisfied in substance and that materials integrally used in production can qualify as raw material.

Issues: (i) whether the benefit of concessional customs duty under the notification could be denied for delay in producing the required certificate from the Ministry of Chemicals and Fertilizers; (ii) whether imported catalyst could be treated as raw material for the purpose of the notification.

Issue (i): whether the benefit of concessional customs duty under the notification could be denied for delay in producing the required certificate from the Ministry of Chemicals and Fertilizers.

Analysis: The notification required production of a certificate, but no time limit for its production was prescribed. The certificate was produced at the appellate stage, and the condition stood complied with in substance. In these circumstances, the delay in furnishing the certificate was liable to be condoned and could not by itself defeat the exemption.

Conclusion: The delay in producing the certificate did not disentitle the assessee to the concessional rate of duty.

Issue (ii): whether imported catalyst could be treated as raw material for the purpose of the notification.

Analysis: The notification covered raw materials and consumables. The imported catalyst was used in the fertilizer plant and its eligibility had to be tested on the basis of its functional role in manufacture. Applying the settled test that a substance may qualify as raw material even if it does not remain in the finished product, the catalyst was held to fall within the scope of the notification.

Conclusion: The imported catalyst was eligible to be treated as raw material for the purpose of the notification.

Final Conclusion: The departmental challenge failed on both grounds, and the grant of concessional duty was sustained.

Ratio Decidendi: Where a conditional exemption notification does not prescribe a time limit for furnishing a supporting certificate, subsequent production of the certificate may amount to sufficient compliance, and goods used integrally in manufacture may qualify as raw material even if they do not remain in the finished product.
