What is expiring, and when
As of April 20, 2026, two photovoltaic module EPDs associated with Hangzhou Dasuo Technology Co., Ltd. are slated to expire on December 13, 2026. Both sit in Division 26 of MasterFormat and were published with UL as the program operator.
- JAM72D10-xxx/MB, JAM72D30-xxx/MB, JAM72D20-xxx/MB, validity through December 13, 2026, MasterFormat 26 00 00, Program Operator: UL.
- JAM72S10-xxx/MR, JAM72S20-xxx/MR, JAM72S30-xxx/MR, JAM54S30-xxx/MR, validity through December 13, 2026, MasterFormat 26 00 00, Program Operator: UL.
Think of an EPD like a boarding pass. It proves identity and gets you through the gate, but only if it is still valid when the flight boards.
Are replacements live yet
We do not see newer replacement EPDs for these specific JAM series modules as of today. That means a gap could open in December if renewals are not submitted and verified in time. EPDs carry a fixed validity window set by the program operator, so timing the refresh matters.

If a gap opens, where might specs go
Photovolatic modules are a crowded field. If these two declarations lapse, specifiers who need current EPDs will likely turn to comparable modules with active declarations.
- LONGi solar photovoltaic modules, valid to January 21, 2029, Program Operator: EPD International AB, Division 26.
- Astronergy CHSM72M series modules, valid to January 30, 2029, Program Operator: EPD International AB, Division 26.
- EGing Solar photovoltaic modules, valid to April 1, 2029, Program Operator: EPD Italy, Division 26.
Each example stays within electrical product scope and points to products that can keep EPD-driven credits in play on certification-driven projects.
Why renewal timing shapes specability
Most project teams will not get into the weeds of LCA modeling, yet they do check whether an EPD is current. If the clock runs out, the product may still be technically excellent, but the spec team will often select a peer with an active declaration to avoid documentation penalties under owner or rating system rules. The age of an EPD rarely matters inside its window, the problem starts when it crosses the line.
Practical moves, starting now
Eight months is comfortable if the workflow is tight. Pin down the reference year, confirm site utilities and material inputs, and align the product model list to match what the market actually buys. Lock the program operator early, verify the applicable PCR version, and set internal checkpoints for data completeness. Treat it like a product launch, not a paperwork chore, and the renewal posts without last‑minute scrambles.
Bottom line for specifiers and manufacturers
Two PV module EPDs tied to Dassogroup reach their end date on December 13, 2026. Replacements are not visible yet, so a precautionary plan is wise. If renewals do not land in time, competing modules from LONGi, Astronergy, and EGing are positioned to absorb the demand. Keeping declarations current preserves pricing power and keeps your product in the conversation when schedules get tight.
