If the southern states couldn’t sell their cotton to Europe they had to sell to the North at whatever price the northern factories wanted to pay.

So, in a roundabout way, yes there were tarrifs on interstate commerce.

The south controlled the tariff issue in the 1850s, so that doesn't fly.

No, there is no tariff between the states of any sort.
