Electrical Conduit EPDs in the US: The data guide
Here’s the definitive 2026 snapshot of Environmental Product Declarations for electrical conduit in the United States. If you make EMT, IMC, RMC, PVC conduit, aluminum raceway, or cable management tube, this is your field report: who’s publishing, which program operators dominate, the PCRs most used, and when renewals will hit. Use it to benchmark your roadmap and set a no‑drama path to your next specification win.
2026 snapshot in one view
The category is active. Over the last five years, 183 conduit EPDs were issued in the United States across 7 manufacturers and 4 program operators, using 4 distinct PCRs. The latest issue we see is an Electrical Metallic Tubing Conduit 38 mm from Penn Aluminum International on Sep 11, 2025, verified by Smart EPD and based on the Part B PCR for Electrical and Telecommunications Conduit, with expiry on Sep 11, 2030.
EPDs issued by year
A late surge reshaped the landscape in 2025. Here’s the five‑year issuance pattern.
| Year | EPDs |
|---|---|
| 2021 | 12 |
| 2022 | 0 |
| 2023 | 21 |
| 2024 | 3 |
| 2025 | 147 |
That 2025 spike signals a new baseline. If you were quiet in 2024, you now compete in a market where conduit EPDs are table stakes rather than nice‑to‑have.
Manufacturers: who showed up
Seven manufacturers account for the 183 EPDs. Western Extrusions (32), Western Tube (22), Wheatland Tube (36), Picoma (36), Nucor (21), Penn Aluminum International (21), and Legrand North and Central America (15). The mix spans steel EMT and RMC, aluminum conduit and tubing, and broader cable management. The picture is simple. Multiple brands now offer product‑specific EPDs across common trade sizes, so “we’ll use the default factor” is less convincing in bids.

Program operators: where conduit EPDs land
UL hosts the largest share with 126 EPDs across 4 manufacturers. Smart EPD LLC verifies 21 EPDs for 1 manufacturer. ASTM International accounts for 21 EPDs with 1 manufacturer. Association P.E.P contributes 15 EPDs for 1 manufacturer. The takeway is diversity exists, yet UL serves several competitors while others are concentrated with single firms. If you are picking an operator for 2026, align on speed, US market recognition, and integration with your sales enablement materials, not just habit.
PCRs that govern conduit in 2026
Four PCRs were used. The Part B PCR for Electrical and Telecommunications Conduit dominates with 147 EPDs and the latest expiries running to Sep 11, 2030. Part B: Designated Steel Construction Products covers 21 EPDs with latest expiry Oct 24, 2028. Product Category Rules for Electrical, Electronic and HVAC‑R Products appears on 12 EPDs and reaches its latest expiry on Sep 30, 2026. Specific Rules for Cable Management Solutions shows up on 3 EPDs with latest expiry Jan 1, 2029. Translation. Most conduit makers chose the dedicated conduit rulebook, which boosts comparability for EMT, IMC, and RMC lines.
Renewal math you can plan around
Expect renewal waves tied to five‑year validity. In the next five years, expiries cluster as follows. In 2026 there are 12 expiries, all tied to the Electrical, Electronic and HVAC‑R PCR on Sep 30. In 2028 there are 21 expiries, all on Oct 24 under the Steel Construction Products PCR. In 2029 there are 3 expiries on Jan 1 with Cable Management Solutions. In 2030 there are 147 expiries between May 21 and Sep 11, almost all under the conduit‑specific Part B. This creates a practical window. If your EPDs ride the 2030 wave, slot verification capacity now so you are not stuck queuing when everyone else renews.
The 2025 flood and what it means for 2026 roadmaps
The market moved in 2025, fast. 147 EPDs hit the registry that year, dwarfing the combined count of 2021 to 2024. That’s a strategic pivot point. Specifiers can now compare product‑specific results across trade sizes instead of falling back to conservative default factors. If your line card lacks coverage at popular diameters or coatings, a gap shows up quickly in pre‑bid screens.
How often did teams use an EPD consultant or service provider
171 of 183 conduit EPDs were prepared with an external EPD service provider, roughly 93 percent. Most manufacturers chose specialized partners to shoulder data collection, modeling, and verification coordination so their operations teams could stay on throughput. If you want that lift without the spreadsheet grind, an EPD partner like Parq handles the heavy data wrangling and keeps momentum through review cycles. It’s quicker, cleaner, and frees your engineers to focus on yield and quality.
Picking the right operator and PCR in 2026
If your competitors publish with the conduit‑specific Part B PCR, following that path usually improves apples‑to‑apples comparability. Caveat. If your product portfolio leans into unique alloys, coatings, or corrosion performance claims, verify that the PCR’s declared unit and boundary conditions capture your advantage. Program operator selection also shapes review cadence and the way EPDs present on public portals. Choose on verification speed, fee structure, and how their output aligns with your submittal format and distributor playbooks. A PCR is the rulebook of Monopoly. Ignore it and the game falls apart.
Notably absent brands in the public registry
As of Jan 17, 2026, we do not see current US electrical conduit EPDs in the public registry under Dura‑Line, Champion Fiberglass, Prime Conduit, or JM Eagle. They may publish under different legal entities or product categories, or may have releases in the pipeline that are not yet visible publicly. If any of these are on your competitive line list, sanity‑check again before bid season so you don’t get suprised by late‑posted EPDs.
What to do next if you are starting now
Audit your top revenue SKUs by diameter and coating to confirm declared units and coverage match what specifiers request most. Map your expiries against distributor line reviews and known RFP calendars. Where you lack coverage, plan a batch approach so one verification swing closes multiple gaps. Keep documentation for facility energy and scrap flows tight for the chosen reference year, and get reviewer questions anticipated before they land. The fastest wins often come from picking the same PCR and operator your closest competitors used, then letting your operations data do the talking.

Note on coverage. This guide uses the global public registry most architects and specifiers rely on. Due to publishing pipelines, some EPDs from the last half of 2025 may not appear yet. If you see a gap, reach out and we will verify the latest record before you make a call.
