As per draft model law, Valuation under GST shall be on transactional value subject to certain conditions. In all other cases, value shall be determined based on comparable value method or computed value method. Computed value method in case of goods, might be arrived based on CAS 4 in GST. As on date there is no such reference to CAS4 certification in GST valuation. But I feel they might refer CAS4 for arriving at computed value for goods.
