An RFQ that says “20 metric tons of MDEA” leaves two details open. Which grade does the plant need, and does 20 metric tons refer to the weight of the delivered product or the MDEA it contains? Answering both questions helps suppliers quote on the same basis.

Neat MDEA

If your plant purchases concentrated N-methyldiethanolamine (MDEA, CAS 105-59-9) for dilution on site, specify the minimum MDEA assay and maximum water content for the product as delivered. List any additional acceptance limits your quality team uses, such as color or specified impurities.

Aqueous MDEA

If you need a premixed solution, state the target MDEA concentration in weight percent and the acceptable range. For example, 20 metric tons of a 50 wt% solution contains 10 metric tons of MDEA. If two offers quote different concentrations, compare the price per metric ton of MDEA contained in each shipment on the same delivery basis.

Activated MDEA

Activated MDEA contains a promoter, such as piperazine, that can improve CO₂ removal in gas treating. For a replacement or top-up order, include the plant-approved formulation or grade reference. If your specification lists both MDEA concentration and total amine content, give those values separately so the supplier can quote against the correct requirements.

What to put in your RFQ

Send China Amines Co., Limited the required grade, assay or concentration range, net quantity as delivered, preferred packaging, destination port and requested delivery date. Include the plant-approved grade reference for formulated solvents and any batch COA requirements. We can then confirm grade availability and quote on the same basis your purchasing team uses to compare offers.
