We are looking to import high-quality furniture in two phases.

Please provide us with your best FOB pricing for these items. In Phase II, our requirements will expand to include desks for teachers as well as furniture for libraries and additional seating. We anticipate needing an extra 400 desks and chairs at that stage. Your prompt response with detailed pricing and any relevant information about lead times and product specifications would be greatly appreciated. Thank you!
