How to Compare MDEA Quotes by Delivered Cost
Two quotes for the same grade of N-methyldiethanolamine (MDEA, CAS 105-59-9) can show different prices per metric ton. If one includes delivery to your plant and the other stops at the port, compare them after adding the costs needed to bring both shipments to the same receiving point.
Confirm what each quote includes
Record the net product weight, packaging type, net fill per package and named delivery point. Check whether packaging, freight and destination handling are included or billed separately. For a port quotation, confirm the charges your team will pay from the port to the plant. Use the same currency and tax treatment for both offers.
Calculate the delivered cost per net metric ton
Delivered cost per net metric ton = total cost to the receiving point ÷ net metric tons delivered
In this hypothetical example, both offers cover 20 net metric tons of the same MDEA grade. The amounts exclude taxes and assume no other charges.
| Cost item | Offer A | Offer B |
|---|---|---|
| Quoted price per net metric ton | $1,500 | $1,550 |
| Quoted shipment total | $30,000 | $31,000 |
| Additional cost to reach the plant | $1,800 | $400 |
| Total cost at the plant | $31,800 | $31,400 |
| Delivered cost per net metric ton | $1,590 | $1,570 |
Offer A starts $50 per metric ton lower. After the remaining delivery charges are included, Offer B costs $400 less for the shipment.
Check how packaging affects the comparison
If two packaging options carry different net weights per shipment, divide each shipment’s total cost by its own net product weight. Where your site incurs a packaging return or disposal charge, include it if it differs between offers. Confirm that your receiving team can handle the proposed package type before choosing the lower-cost option.
