(OP)
mil-c-5541E only specifies class, while mil-dtl-5541F added type I and II. type II says no hexavalent chrome.
if type II is due to RoHS, is the chem coated aluminum part per type I hazardous or just the chemical (solution)used in the process? we forgot to specify type II and the customer is giving us hard time.
thanks.

If your customer is rejecting these parts because they might have used a chem film process using hexavalent chrome, then either you did not follow their instructions, or they did not provide specific instructions to you. In our modern world, it is often a requirement for components delivered to an OEM that they comply with strict environmental regulations at every step along the way. Such as no cadmium, no lead, no beryllium, or no hexavalent chrome.
