Gusts do not apply during planning. But they do have to be taken into account for landing (and takeoff). given the additional company restriction I’d ask for instaneous winds. If these were beyond the company limit just before landing (not necessarily at MDA/DH) even if fully stabilised I’d go around. If instaneous winds were not available I’d divert. This is obviously the company’s intention and it’s what you are paid to do and must have been budgeted into their operating costs. That the aircraft is still within its crosswind limits and other operators of the same type are landing is irrelevant.
