With the exception of Tony Chachere's, most of these LA seasonings are custom blended and packed by Targil, which is also located in opelousas, la.
They will blend according to your specs, or you can choose from hundreds of their own blends.
You can use their label or your own homemade label, which they will also custom design, print and attach.
I make my own which is based on a box of salt(26oz) plus other seasoning. I use about 3/4 box of salt and more spice.
Lots of the car dealerships get targill to pack seasoning for them.
Even lawyers in NOLA have their own seasoning brand! Lol. @Peter1469
