Air carrier Captain reported a communication breakdown between the Captain and two FAA Inspectors during a 'Ramp Check' in which Inspectors were tracking two Hazmat items while the Captain stated two items were packaged in one box. Ultimately the Hazmat was unloaded and the flight departed safely.

Narrative

FAA Hazardous Material Safety Inspection. A few minutes prior to pushback 2 FAA inspectors came board the Aircraft introduced themselves and requested copies of our final dangerous summary and PIC acknowledgment. I provided both to them and they stated there was a discrepancy between what the hazardous cargo handlers reported versus what was loaded on the aircraft. They were tracking two hazardous cargo items for shipment (same as our final dangerous goods summary); however; they only witnessed one box being loaded. We discussed the issue with both the load planner at ZZZ; the FAA Inspector; centralized load planning via Dispatcher conference call but after 30 minutes the Inspector was not satisfied with the answers given by the Ramp Personnel at ZZZ. Ultimately; it was determined that both packages were in one box; however; the main Inspector was not happy with that solution. So a joint decision was made between myself; centralized load planning and station to remove the packages so we could depart. Additionally; the Inspector stated there was a ramp bulletin that requires the hazardous cargo personnel provide the PIC a hard copy of the paperwork; regardless of whether we receive a ACARS digital final dangerous good summary. I explained I was not aware of any such bulletin; I was abiding by Company FOM procedures; and as far as I know; was in full compliance of my required duties. The Inspector was polite; seemed to lay the blame on our Ramp Personnel; however; he repeatedly told me this was a 'minor issue' and I could make a decision to depart at any time. However; I find it strange that an Inspector would say we are in noncompliance; and then offer me the opportunity to depart without resolving the issue.
