I'm currently exploring options for building materials and need some info about your offerings. Specifically, I'd like to know what your minimum order quantities are for various products. Additionally, if you could provide a product list or catalog, that would be super helpful in understanding what you have available. Also, I'm curious about your shipping capabilities—do you ship to Tanzania? Getting clarity on these points will really help me in making a decision. Looking forward to your prompt response!
