Declaration requirement for tobacco packing machines establishes manufacturer particulars and undertakings to ensure capacity determination and duty compliance. Form-1 mandates that manufacturers supply identifying and premises details, inventory and operational intentions for single-track and multiple-track packing machines (available, installed, and to be operated), machine identification and maximum packing speeds for production of pouches with and without lime tube across retail denominations, goods descriptions and retail price denominations, and a factory ground plan allocating machines by denomination. It requires a signed declaration undertaking truthfulness, payment of additional excise duty if particulars are incorrect, supervised addition/removal of machines by Central Excise Officer, and agreement to comply with the Rules.
