However, "hair lotion" is specified under Tariff Item 14F. Since May, 1974, till 13th July, 1982, the Excise Department did not raise any claim in regard to "liquid hair dyes" under Tariff Item 14F and no excise duty was demanded in respect of the said item.

2. With effect from 1st March, 1975, Tariff Item 68 was introduced as a residuary entry in the Central Excise Tariff relating to "all other goods not elsewhere specified". As a result, all goods became excisable. Inasmuch as, it had been accepted by the Excise Department that "liquid hair dye" did not fall under Tariff Item 14F, the appellant started paying duty on the said product under Tariff Item 68 with effect from 1st March, 1975.
