Is the ETH address yours or and exchange? If its yours, then it might be possible to recover.
Exchange. But I sent USDT to ETH address.
If you are sure that the address belongs to the exchange then they should be able to recover your funds. They can refund your coins if the funds are there in their wallet.
As @OmegaStarScream said, if the USDT is an ERC20 token then they support that tokens.
