Where do we find exemption for high sea sales

There is no exemption that is specifically issued for high sea sales. All import of goods are liable to IGST not under section 5(1) but under the proviso which takes imported goods into the Customs Act for determination of the liability. And ‘the point’ at which customs duties are levied is when bill of entry for home consumption is filed. In case of high sea sales, such a bill of entry is filed only by the final recipient (high sea buyer).

What is the effect of omitting to avail exemption

GST would have been charged, collected and deposited along with claim of ITC. If the exemption was absolute, explanation to section 11 makes it clear that the exemption must be availed. In case of omission to avail exemption, the tax charged and collected being ‘in the name of GST’ is liable to be paid to the Government under section 76. More importantly, the ITC availed in error will also be denied.

What is the effect of mistaken claim of exemption

GST applicable will be recovered with benefit of ITC available only to the limited extent of the time available within section 16(4) when this mistake is realized. There is no estoppel that ITC must be availed because claim of credit is through the return filed under section 39 (section 16(2) refers) and not from the receipt of tax paid supplies.
