Customer currently has 200 amp service to house. Also has an out building 250 feet away where heavy equipment will be used. Wants a 400 service. At the new meter base, will the line going to the outbuilding be considered a feeder? Thinking I will need a 200A disco for it next to the meter base. Any help appreciated, of course my first 400 amp service is a little more complex.

The way you have it worded, it will be a feeder, you will be on the load side of your disconnect so its not a service to the out building.
Wants a new meter base with a disconnect beside it........need a 200A disco for it next to MB...
So, your feeder to the out building will be a feeder from the load side of the 200 A disco. The service conductors stop at the line terminals.
If run PVC, you'll need an EGC and grounding electrode, if available or ground rode or 3/4 rigid pipe.
If you put a disconnect at the out building it can be out side or immediately inside.
Side note; have you considered voltage drop? At that 250 ft. and "heavy equipment".
I suggest an SPD for your heavy equipment, likely to have some electronics.
Is this considered at a dwelling type location....customer has 200 A service to
house....
I don't know anything about your city electrical jurisdiction but first responders shall have an emergency disconnect or use the 200A disconnect to meet 230.85 rule and 230.85(E) (1) (2)
Marking.
Thanks for reading.
