Taiwan China Steel Corp. has secured two Environmental Product Declarations (EDP) for its wire rod, boosting orders for “green” fasteners, Fastener World reports.

CSC recently completed EPD certification for wire rods, electro‑galvanized, and hot‑rolled pickled steel coils, allowing downstream fastener, electronic component, and automotive‑parts manufacturers to enhance their “green” competitiveness.

EPDs are based on ISO 14025 standard, using life‑cycle assessment (LCA) to quantify impacts on items such as ozone depletion, acid rain, eutrophication, and climate change across stages from raw‑material extraction to disposal. The figures after then verified by independent third‑party groups so downstream buyers can evaluate products more transparently.

In addition, the steel manufacturer has collected environmental‑footprint data for steel plates, hot‑rolled, cold‑rolled, hot‑dip galvanized steel, and electrical steel coils, obtaining certificates from UL Solutions and The International EPD System covering key applications such as building structures, public infrastructure, and motors.

A product’s carbon footprint and related environmental impact figures have become key purchasing criteria, as well as a requisite to entering international markets.

The U.S., Europe, and Southeast Asian countries have tightened environmental regulations for steel products.
