澳大利亚采购需求：露台、墙面、围栏、瓷砖、凉亭及栏杆、花箱

I'm reaching out to get some clarity on the minimum order quantities for your products. I'm interested in understanding how many units are required for a purchase to ensure I meet your standards. Additionally, it would be helpful if you could provide information on any pricing tiers associated with different order quantities. This will greatly assist me in planning my future orders and make our potential collaboration smoother. Thanks!
