A number of commercial products that I've worked on met the Class B limits with margin. But since they were commercial products, and were not marketed to the "public", marketing stayed with the Class A compliance claims to avoid any confusion for the customs, which meant a sizable margin to the A limit!. Was it more expensive to make those margins to the limits? Just a bit, a lot more care in the layout took care of it. Generally two more layers did it, along with a few layout tricks. And being expensive commercial products with lots of $$ margin to start with, no real concern. And with those margins to the limit, go ahead and make some changes, they probably won't affect the DOC.
