Issues involved:
1. Whether the appellant is manufacturing SMS explosives exempt from Central Excise Duty.
2. Classification of Emulsion Matrix under Central Excise Tariff Act.
3. Whether Plot Nos. 48 and 49 constitute one unit for manufacturing explosives.
4. Allegations of non-payment of Central Excise Duty and recovery from customers.

Detailed analysis:
1. The appellant, a manufacturer of explosives, mixes duty paid ingredients in a vehicle at mine sites to produce SMS explosives exempt from Central Excise Duty under specific notifications. The mixing process varies based on blast requirements, and the exemption was confirmed by CBEC after a representation made by the appellant in 1993-94.

2. The Commissioner classified Emulsion Matrix as a chemical product under Chapter 38 of the Central Excise Tariff Act, disputing its previous classification. This classification was part of the Show Cause Notices issued by the Central Excise Authorities.

3. The Central Excise Authorities alleged that Plot Nos. 48 and 49 should be considered one unit for manufacturing explosives, challenging the separate registration and operations of the two plots. The use of a vehicle for mixing ingredients at mine sites was a key point of contention.

4. Show Cause Notices were issued for recovery of Central Excise Duty, alleging non-payment and recovery from customers. The Commissioner concluded that the appellant collected Central Excise Duty but failed to deposit it, leading to demands and penalties. The appellant argued that the non-supply of a crucial Board's letter caused prejudice and denial of natural justice, seeking a de novo adjudication.

The Commissioner's order was set aside, and the case was remitted back for fresh adjudication, allowing the appellant to address all issues and defenses. The need for transparency in supplying crucial documents and ensuring natural justice was emphasized, leading to the decision for a new adjudication process.
