Quary Regarding ITC

A business involved in raw cotton trading, ginning, and pressing faces a query regarding Input Tax Credit (ITC) on outward supplies. The client purchased lint at a 5% GST rate and made deemed exports at 0.10%. The core question is whether the client can claim the full ITC, apply for a refund of the 4.90% difference, or if they need to reverse this amount. Two potential options are presented: claiming a refund of ITC without paying outward GST, or paying outward GST and then claiming the entire outward tax as a refund, though both involve significant documentation and practical challenges.
