I am currently looking for a Structural Insulated Panel manufacturer that allows their product to be used in Seismic Design Category D. In addition, the SIP's need to be able to have an aspect ratio greater than 2:1. Many of the reports on the ICC Evaluation Service indicate that the product may only be used in Seismic A,B, or C and limit the SIP's to aspect ratio of 1:1 or 2:1. Any suggestions?

I would say no per the following
The Federation of American Scientists - Analysis of the Seismic Performance of SIPs (from "The fact that SIPs are not directly addressed in ASCE 7 is a substantial issue for the industry, as neither AC04 nor the IRC/IBC addresses the requirements for high seismic design categories (D and E). Seismic applications have been a point of contention in discussions over developing new acceptance criteria for SIPs, and a source of complaint regarding AC04 and AC05. Current acceptance criteria do not address the requirements for high seismic design categories (D and E), such as in California, Oregon, Washington, and Alaska where SIPs are viable products. While the industry waits to develop and adopt new acceptance criteria (either AC236, or possibly AC130, Acceptance Criteria for Prefabricated Wood Shear Panels) all ICC-ES evaluation reports on SIPs will continue to not specifically recognize the use of SIPs in high seismic design categories. This imposes a considerable restriction to the market access of SIPs in
West Coast.
The SIP industry is currently working towards achieving recognition in seismic codes by developing an ANSI standard with the APA, and by developing new acceptance criteria. However, there are two major steps required to overcoming this obstacle: identifying a testing method that is appropriate for the seismic evaluation of SIPs, and conducting further testing to better understand how SIPs function under seismic loading. (These issues are addressed in more detail in this report concluding in a roadmap for the industry as envisioned by SIPA’s largest supporter, the APA.)"

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.
