I am interested in sourcing gibberellic acid and would like to gather more detailed information. Specifically, I need to know about the available grades, packaging options, and pricing structure for bulk orders. Additionally, it would be helpful to understand your production capacity and lead times for delivery. Please also provide any relevant certifications or quality assurance measures you have in place. I'm keen to establish a long-term relationship, so knowing your terms for repeat orders would be beneficial. Looking forward to your prompt response with the details!
