[MW:27064] WPS for A105

Dear Experts,
I have a WPS qualified as per ASME Sec IX for ASTM A106 with AISI 4130.Now we have a requirement to weld A105 with AISI 4130. As I understand 4130 is unlisted material as per ASME and we need to qualify WPS every time. Kindly confirm the same or advice. Or can I go ahead with same WPS as there is no requirement for Impact testing. 
Thanks in adv.
