According to section 31(1) of CGST Act 2017, A registered person supplying taxable goods shall issue a tax invoice, before or at the time of removal of goods for supply to the recipient, where the supply involves movement of goods.
Further as per rule 55(1) of CGST rules 2017, delivery challan can be issued in case of inter alia transportation of goods for reasons other than by way of supply.
As per section 10(1)(a) of IGST Act 2017, POS of goods in case of supply involving movement of goods shall be place where movement of goods terminates.
As per section 7 of IGST Act 2017, where the location of the supplier and the POS are in two different states then this shall be treated as a supply of goods in the course of inter-State trade or commerce.
According to section 2(25)of the Customs Act 1962, "imported goods" means any goods brought into India from a place outside India but does not include goods which have been cleared for home consumption.
Further as per section 12(1)of Customs Act 1962, customs duties shall be levied on goods imported into, or exported from, India.
Query 1:- As per section 31(1) of CGST registered person registered in Rajasthan needs to issue a tax invoice for the supply of goods (3000Kgs) at Mumbai for which POS will be the Mumbai (as per section 10(1)(a) of IGST) and will results in inter-State supply of goods (as per section 7 of IGST) for which IGST shall be charged. Further for the remaining goods (7000Kgs) transporting from Nava Shera to Rajasthan delivery challan needs to be issued (as per rule 55(1) of CGST rules)
Therefore the process adopted in the given case is correct and is according to the provisions of the GST law.
Query 2:- In the given case goods (10000Kgs) are cleared from the port therefore it will not qualify as imported goods (as per section 2(25) of the Customs Act) and since customs duties are levied only on goods imported into, or exported from, India therefore customs duties will not be levied once goods cleared from port for home consumption.
Since there is no relation of the Customs Act in the given case after goods has been cleared and also there is no restriction for selling goods in transit in GST laws and its rules, therefore goods once cleared from port for home consumption can be sold in transit.
