Congrats, Siemon: first EPDs for structured cabling

What Siemon just published

Siemon released its debut EPD in June 2025 for a shielded Z‑MAX Category 6A telecommunications outlet, a product‑specific declaration under the wires and cables ruleset hosted by EPD Hub. Later in December 2025, Siemon added a family EPD covering Category 6 and 6A plenum 4‑pair communication cables. Both are listed with EPD Hub as the program operator, with Aecon Group Inc. noted as the LCA developer. The mix covers a critical endpoint component and the horizontal cabling that feeds it.

Why this matters in the spec economy

Structured cabling is the nervous system of modern buildings and data centers. When a product lacks a current, third‑party verified EPD, design teams often model it with conservative defaults that can nudge bids away. With outlet and cable EPDs live, Siemon can now stay in more submittal stacks and avoid those generic penalties that quietly cost specs.

A quick read on Siemon’s core business

Siemon makes network infrastructure for commercial buildings and data centers, especially copper and fiber connectivity, cabinets, and cable management. These first EPDs land in the heart of day‑one scope that IT, electrical, and low‑voltage trades touch on almost every job. It is a smart opening move that meets where specs already ask for proof.

Competitive snapshot

CommScope has multiple product‑family EPDs for Category 6 and 6A LAN cables and fiber raceways across operators like ASTM, UL, and EPD Norway, so it has been visible in bids for a while. Legrand’s North America unit publishes a broad slate that includes RJ45 connectors, cable trays, and fiber components, which keeps its portfolio specification‑friendly across entire BOMs. Panduit shows no current structured‑cabling EPDs as of today, a gap that matters when owners and GCs request declarations in submittals.

What changed for project teams

The outlet EPD reduces friction at the telecom faceplate, where submittals often flag missing documentation. The cable family EPD plugs a larger hole across typical copper runs. Together they make it easier to keep a Siemon‑to‑Siemon pathway in submittals without swapping to a brand that only wins on paperwork.

Guidance if you are planning the next wave

Extend coverage to patch cords, patch panels, cable management, and common fiber SKUs. Keep scope language crisp, align with the rules competitors already use, and time publications so that renewals do not cluster. Pick an LCA partner who owns the heavy data wrangling inside your org, not one who hands you a spreadsheet and disappears. It saves weeks, sometimes months, when procurement is hot.

Can we find these on Siemon’s site right now

We could not locate a public EPD library or product pages hosting the new declarations on siemon.com at the time of writing. Visibility matters for estimators and sustainability reviewers, so adding a central sustainability or documentation page is a quick win. Make it one click from product pages, and keep PDFs named plainly for search. This sounds minor, but it helps alot during submittal rush.

Bottom line for the spec race

Siemon is now playing on the same field as brands that have used EPDs to stay shortlist‑ready in cabling. The June 2025 outlet EPD and the December 2025 cable family EPD signal a credible start. Keep publishing across adjacent SKUs, keep the cadence steady, and those declarations will pull real weight in bids where transparency is now the baseline.
