美国采购需求：营养保健品

I'm looking to source high-quality Humic and Fulvic acids, along with Seaweed extract for our upcoming product line. It's essential that the materials are sourced sustainably and meet our quality standards, as we prioritize eco-friendly options in our formulations. We are interested in understanding the different options available, including any specifications or certifications you might have. Additionally, please provide information on your minimum order quantities, pricing details, and potential lead times for delivery. We're in the process of evaluating suppliers, so insights into your production capabilities and any samples for testing would also be appreciated. Looking forward to your prompt response!
