伊朗采购需求：无机肥、有机肥、农药、植物生长调节剂

I'm reaching out to inquire about the availability and pricing for a few chemical products we need for our operations. Specifically, we're looking for high-quality potassium salts and other growth regulators in bulk quantities. We require competitive pricing for 200 kg of one potassium salt, 200 kg of another growth regulator, and 100 kg of a gibberellic acid formulation. Please provide detailed information on lead times, shipping options, and any available discounts for larger orders. Thank you!
