Unintentional collisions wouldn't happen: each manufacturer gets a unique ID, and in turn gives each product type, and each instantiation of each product of that type (e.g., this particular 12 oz. can of Coke) a unique serial. Only that particular manufacturer gets to assign codes with its manufacturer ID (or, as EPCglobal calls it, an EPC Manager Number) in it, and presumably won't screw up when it assigns its own IDs to its own products.
