I'm interested in sourcing high-quality humic acid flakes, specifically potassium humate, for our upcoming projects. Could you please provide details on the product specifications, including the available grades and any relevant certifications? Additionally, I would like to know your pricing structure, minimum order quantities, and lead times for delivery. It would be great if you could share any samples or datasheets you may have. Looking forward to your prompt response!
