澳大利亚采购需求：饮水机、饮水冷却器、净水器、滤水器、制冰机、苏打水机

I'm looking to develop an OEM production line for a new shower filter brand targeting the Australian and Korean markets. The main components I'm interested in are a transparent shower head body with options for high-pressure and fine spray, logo printing capabilities, and a sleek, minimalist design. Additionally, I need color-changing filter cartridges that react visually to water impurities, featuring replaceable systems with KDF and Vitamin C options, alongside custom packaging that reflects my brand. Please provide detailed information on the minimum order quantities for both the shower heads and cartridges, unit pricing for each component, sample costs, and shipping fees to Brisbane, Australia. I would also like to know your production lead times and if you can assist with small-batch OEM for initial orders. Lastly, share any existing models you have available and their certifications like CE and RoHS. Looking forward to your response!
