Modvat credit limitation does not bar later differential duty credit where the original credit was taken within time.

Modvat credit under Rule 57E was considered in relation to differential duty paid after the original clearance documents, and the six-month limitation was held applicable only to duty evidenced in the prescribed documents. The time bar could not be extended by analogy to later-paid differential duty where the initial credit had been taken within time. The assessee was therefore entitled to correct the credit to reflect the actual duty paid, and the limitation objection to denial of credit was not sustainable.

Issues: Whether Modvat credit of differential duty taken on the strength of a certificate issued under Rule 57E of the Central Excise Rules, 1944 was barred by limitation for being taken beyond six months from the date of the certificate.

Analysis: The credit claimed related to differential duty paid subsequently and not to duty originally shown as paid in the basic clearance documents. The reasoning accepted that the six-month limit under the Modvat scheme could govern only the duty amount evidenced by the specified documents and could not be extended by analogy to cases where the duty itself was paid later. It was also noted that where initial credit was taken within time, later credit of the additional or differential amount was not hit by the amended limitation bar, and that the assessee retained the right to correct the credit to the actual duty paid.

Conclusion: The limitation objection was not sustainable and the Modvat credit could not be denied on the ground of delay.

Ratio Decidendi: A time limit under the Modvat rules applies only to credit of duty shown in the prescribed document and does not bar credit of duty or differential duty paid subsequently when the initial credit was otherwise within time.
