Dear experts
Demurrage charges in sea transportation are incidental charges that arise when the consignee delays clearance/return of containers beyond the free period. Such charges are to be treated as additional consideration for the principal supply of transportation service. Accordingly, in my opinion, they are taxable at the same rate as freight in terms of Section 15(2)(c) of the CGST Act, 2017.
Many are under the misconception that such chrages are for "tolerating an act" falling under Sl. No. Entry 5(e) of Second Schedule to the CGST Act.
Plz validate.

Sh.Sadanand Bulbule Ji,
Sir, I wholly concur with the views of Sh. Kalleshamurthy Murthy, Sir. These are compensation charges and can never be treated as income. So no consideration. Moreover, such charges are covered under the category of NOT tolerating an act and NOT under the category of tolerating an act. Hence out of the scope of Schedule-II. NOT taxable. Most of the case laws are in favour of the assessees.
