I'm looking to inquire about the availability and pricing of certain chemical products. Specifically, I need a detailed quote for two different types, focusing on their specifications and any bulk purchase options you may offer. Please include information on minimum order quantities, lead times, and payment terms as well. Additionally, if there are any certifications or quality standards that these products meet, that would be great to know. I'm interested in understanding your production capabilities and any potential for custom formulations, should that be an option. A prompt response would be appreciated as we are keen to move forward quickly.
