澳大利亚采购需求：海苔粉、东革阿里提取物、α-熊果苷、曲酸二棕榈酸酯、赤藓糖醇、罗汉果提取物

We're interested in sourcing a specific herbal extract, and we'd like to know more about your offerings. Could you provide us with the price for 2 kg of the extract powder? Additionally, it would be helpful to get an estimate on shipping costs to Queensland, Australia, so we can assess the overall budget for this purchase. Please include any details regarding lead times, packaging options, and bulk order discounts if available. We're looking to establish a reliable supply chain, so your prompt response would be greatly appreciated. Thanks in advance for your help!
