Looking for ISCC certified UCO only from genuine suppliers

I am looking for ISCC certified UCO, solely from genuine suppliers. Too often brokers offer an offer and have no idea who’s the actual seller. I have three genuine seasoned experienced clients that don’t play games. When an offer and seller is genuine they step in immediately, provided the price is right. We want UCO that does NOT contain palm oil or animal fat. Any origin will do. We also require CIF shipment to Rotterdam Netherlands. Price not lower than 500/ton, and not higher than 550/ton.

Specs: FFA max 3%, Iodine min 100, MIU max 1%, Sulphur max 18.
