Captive consumption valuation excludes post-manufacture cutting charges and unrelated overheads from production cost.

For goods captively consumed, valuation under section 4(1)(b) read with rule 6(b) must reflect the cost of production of the excisable product at the relevant manufacturing stage, together with reasonable profit. Post-manufacture cutting charges from sheet to strip were treated as outside the production cost of camel back, and unrelated administrative overheads were likewise excluded from the cost base. The analysis stressed that the product was assessed at the sheet stage, so later conversion expenses could not be added unless they formed part of that stage's manufacture. The exclusion of those items from valuation was therefore upheld.

Issues: Whether, in valuing camel back captively consumed in the manufacture of retreaded tyres, the cost of production could include cutting charges from sheet to strip and administrative overheads.

Analysis: The valuation had to be made under section 4(1)(b) of the Central Excises and Salt Act, 1944 read with rule 6(b) of the Central Excise (Valuation) Rules, 1975, under which the nearest ascertainable value, or failing that the cost of production or manufacture with reasonable profit, governs captive consumption. On the facts, the camel back was assessed at the sheet stage, and the later cutting of sheets into strips was a post-manufacture activity. If the assessment stage were shifted to strips, the corresponding wastage would also have to be accounted for, but the valuation on the record could not justify adding such cutting expenses. The gross profit already reflected salaries and administrative elements, and overheads not connected with the manufacture of camel back sheets were not properly includible in the cost base.

Conclusion: Cutting expenses from sheet to strip and unrelated administrative overheads were not includible in the cost of production for valuation purposes, and the exclusion of those items was upheld in favour of the assessee.

Ratio Decidendi: For goods captively consumed, valuation under section 4(1)(b) and rule 6(b) must be based on the cost of production of the excisable product up to the relevant stage, together with reasonable profit, and post-manufacture or unrelated overheads cannot be added unless they form part of that production cost.
