Because these two contracts are both formula-based pricing, there may be a second delivery, but I did not find it in your modified contract. I think it is better to be the same as the previous contract: if the final price is higher than the temporary price, you Make a second presentation (settled in the letter of credit), otherwise settle from TT outside the letter of credit.

Since both contracts are formulaical, there may be secondary payments, but I didn't find them in the contract you modified, and I think it's better to go to the previous one: if the final price is higher than the provisional price, you make a secondary payment (settled in the L/L) or settle the TT outside the L/L.
