Assembling Product in Two Facilities

We are attempting a new process and I need some help from the experts who work in more robust manufacturing environments.

We have two facilities across the United States - most of the manufacturing is done on the West Coast, but we export the product to another country from the East Coast. We just purchased equipment for the East Coast facility only. But, it will need to be used for every exported item.

For example's sake, we fill a tube of goo with product at the West Coast facility and then send it to the East Coast facility to add an insert and shrink band.
