Separate transportation arrangements and suppression can expand assessable value, extend limitation, and attract penalty, with ad valorem limits still controlling.
Where goods are sold under a separate transportation arrangement and delivered at the buyer's premises, only actual transport expense is deductible and the assessee must disclose the delivery structure; on the facts, the excess realised was includible in assessable value. Non-disclosure of the separate transport contract and billing amounted to suppression, supporting extended limitation and penalty, although the demand beyond five years was time-barred. For chlorine, which was not chargeable on an ad valorem basis during the relevant period, the alleged excess realisation could not be subjected to duty, and limited relief was warranted on verification.
Issues: (i) Whether the additional amount realised under a separate transportation arrangement was includible in the assessable value and whether the factory gate price was ascertainable; (ii) whether the extended period of limitation and penalty were justified; (iii) whether the extra realisation relatable to chlorine, which was liable to specific rate of duty, could be subjected to duty.
Issue (i): Whether the additional amount realised under a separate transportation arrangement was includible in the assessable value and whether the factory gate price was ascertainable.
Analysis: The valuation dispute turned on the nature of the contracts and the actual place of delivery. The Court held that the sales were negotiated transaction-wise, with separate arrangements for supply and transportation, and that the factory gate price could not be treated as ascertainable on the facts. In a delivery-at-buyer's-premises situation, only actual transportation expenses were deductible, and the appellant was required to disclose the arrangement for delivery at the buyer's place. The Court rejected the contention that excess collections could be neutralised by instances of lesser collection in other years and held that the alleged depression of price stood established.
Conclusion: The additional amount realised in excess of actual transportation expense was liable to be brought into the assessable value, and the assessee failed on this issue.
Issue (ii): Whether the extended period of limitation and penalty were justified.
Analysis: The Court found suppression in the non-disclosure of the separate transportation contract and separate transport billing. That suppression attracted the extended period of limitation and also supplied the requisite element of mens rea for penalty. At the same time, the Court restricted the demand to the normal time limit for the period beyond five years preceding the show cause notice.
Conclusion: The extended period and penalty were upheld, but the demand beyond five years was set aside as time-barred.
Issue (iii): Whether the extra realisation relatable to chlorine, which was liable to specific rate of duty, could be subjected to duty.
Analysis: The Court accepted that chlorine was not assessable on an ad valorem basis during the relevant period and therefore the alleged excess realisation on transportation could not be subjected to duty for that commodity. The adjudicating authority's omission to consider this aspect was corrected by granting relief on verification.
Conclusion: Relief was warranted in respect of chlorine.
Final Conclusion: The appeal substantially failed on valuation and limitation, with limited relief confined to chlorine and the time-barred portion of the demand.
Ratio Decidendi: Where goods are delivered at the buyer's premises under a separately structured transport arrangement, the assessee must disclose the arrangement and actual transportation expense is the only deductible element; non-disclosure may justify suppression-based extended limitation and penalty, while commodities not chargeable on an ad valorem basis cannot be subjected to such excess realisation adjustment.
