But generally, for inward and outward remittance, I usually provide the following purpose code to the banks.
Inward Remittance: "P0019 - Receipts on account of Sale of non-produced non-financial assets (Sale of intangible assets like patents, copyrights, trademarks etc ., use of natural resources) – Non-Government"
Outward Remittance: "S0019 - Acquisition of non-produced non-financial assets (Purchase of intangible assets like patents, copyrights, trademarks etc., use of natural resources) – NonGovernment"
