Could you provide me with the net FOB pricing for your FT-IR model, including options for air freight to Islamabad Airport, Pakistan? It's important for us to understand the total cost involved in getting the unit delivered, so please include any additional charges or fees that may apply. Additionally, if there are any variations in pricing based on shipping timelines or preferred carriers, I'd appreciate that information as well. We're looking to make a decision soon, so prompt feedback would be greatly beneficial. Thanks!
