Agents, brokers, distributors, repackers and relabellers should pass every piece of quality or regulatory information in both directions, from the API or intermediate maker to the customer and back again. Whoever supplies the customer should give the original manufacturer's name and the batch numbers supplied. The agent should also identify the original manufacturer to regulators on request (the manufacturer may respond to the authority directly or through its authorised agents). Certificates of analysis should follow section 11.4.
