Buyer Looking For Cooking Oil

We are currently looking for high-quality USED COOKING OIL suppliers and would like to request a quotation based on the following requirements:

Specifications:
Quantity: 500 Tons
Destination port: Barcelona, Spain, Es (BCN)
Trade term: FOB
Payment term: T/T
Ship to: Spain
Moisture And Impurities: 0.02 %
Concentration: 0.2%
Specific Gravity: 0.915 @ 25°c
Iodine Value: 120

Please provide your unit/total price and lead time. If you have any catalogs or certificates, please share them for our reference.

I am an intermediary based in Douala, Cameroon, working with a buyer in Spain who takes used cooking oil (UCO) in full flexitanks of about 24,000 L (22 to 24 tonnes), per month, recurring, for a long-term partnership with no maximum volume.
If you can supply this, please send me:

Your registration number and address
Your port of loading and where the oil is stored (do you have a tank and pump for 24,000 L?)
Your real monthly capacity, and how you source the oil
A recent lab report (FFA, moisture and impurities) and your ISCC certificate number, if you have one
Your price per tonne FOB for a full flexitank, and your payment terms

The oil would ship directly from your port to the buyer's factory in Spain. It must be filtered, with as little water as possible, and kept out of the sun. Quality is judged by specification, with a price reduction for each point outside the limits, and the buyer pays about 5 days after the container arrives at the factory. A partial advance after loading is being negotiated, and it isn't confirmed.

I act as an introducer. My commission is agreed in writing and paid only after the buyer's payment has arrived. I never ask a supplier for money.

Thank you.
