StoneTrades — March 31, 2026

Two EU stone import regulations taking effect in 2026 are simultaneously reshaping how natural stone is sourced, specified, and documented for the European market. The revised Construction Products Regulation (CPR, Regulation 2024/3110) entered application on January 8, 2026, imposing mandatory Global Warming Potential (GWP) declarations on construction products — explicitly naming granite, marble, limestone, and travertine among covered categories. At the same time, the EU Carbon Border Adjustment Mechanism moved from its transitional phase into full compliance from January 1, 2026, with a December 2025 Commission proposal to extend its scope downstream that will affect cost structures across the stone supply chain. For buyers sourcing natural stone for European commercial or hospitality projects, both changes have direct procurement consequences.

What the New CPR Requires from Stone Suppliers

Regulation 2024/3110 — published December 18, 2024, and applicable from January 8, 2026 — expands mandatory performance declarations for construction products sold in the EU. For natural stone, the change is material. Manufacturers and importers must now declare Global Warming Potential (GWP) under Annex II(a–d) of the regulation. The product categories specifically covered include granules, chippings, and powder of marble, travertine, ecaussine, granite, porphyry, basalt, sandstone, and other monumental stone.

Two additional compliance requirements follow in phases. From January 2030, the declaration scope widens to Annex II(e–m), covering a broader set of environmental indicators. Full lifecycle environmental reporting becomes mandatory by January 2032. But the immediate hurdle — the GWP declaration for 2026 — is what procurement teams are already asking about.

The mechanism delivering this data is the Digital Product Passport (DPP). Under the revised CPR, covered construction products require a centralized digital record containing technical specifications, performance data, and carbon footprint information. For stone imports, this means suppliers without Environmental Product Declarations (EPDs) for their specific products face real risk of specification rejection in EU tenders and projects. Industry EPDs for natural stone — covering cladding, flooring and paving, and countertop applications — have been developed and published, giving compliant suppliers a clear documentation pathway.

CBAM's Indirect Effect on Stone Import Costs

Natural stone itself is not currently a CBAM-covered product. The Carbon Border Adjustment Mechanism, which entered its definitive compliance phase on January 1, 2026, applies to cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen. Stone quarried in China, Turkey, India, or Brazil does not carry a CBAM certificate obligation at the point of import.

The indirect effects, however, are not negligible. Seaworthy wooden crates — the standard packaging for slab shipments at FOB origin — rely on steel hardware and steel banding. A-frame bundles for large granite slabs (typically 240×120 cm or 260×120 cm) use steel frames. In project installations across Europe, stone is mechanically fixed with steel anchors and brackets. The proposed December 2025 expansion of CBAM's downstream scope — targeting approximately 180 products incorporating steel or aluminium — may eventually reach stone-adjacent fixings and curtain wall components. That proposal has not yet entered force, but procurement teams handling multi-year supply contracts have reason to model the cost exposure.

A separate pressure point: EU importers of CBAM-covered goods weighing more than 50 net tons annually were required to apply for authorized declarant status by March 31, 2026. While stone importers are not yet in scope, the registration and reporting infrastructure now in place sets the operational precedent for any future scope additions.

How Procurement Specifications Are Already Shifting

European architects and procurement managers — particularly on public sector and hospitality projects — are updating specification language ahead of tender deadlines. The practical effect is straightforward: stone suppliers without an EPD for the specific product category are being removed from approved vendor lists.

For beige marble varieties sourced from Turkey or Iran — including materials like Persian Grey (Mohs 3–4, typically supplied honed for wall applications) or Classic Beige from Oman — the supply chain documentation burden has increased. Quarry-level carbon data must now be traceable back through the production process: gang-saw cutting, CNC infrared precision cutting, polishing, and surface finishing each carry energy inputs that feed into GWP calculations. Suppliers running fully automated polishing lines with documented energy consumption per square metre are better positioned to generate compliant EPD data than those operating older batch-process facilities.

Granite, by contrast, enters the 2026 regulatory environment with stronger documentation foundations. Granite's higher Mohs hardness (typically 6–7) and its established market across exterior cladding, countertops, and paving means there is more existing EPD coverage for granite categories. Brazilian black granite, Indian red granite, and China Green — a mid-priced option with uniform texture suitable for indoor-outdoor use — all fall within product families where industry EPDs can be referenced, though site-specific EPDs offer stronger specification compliance.

Limestone sits in a more complex position. Popular EU-market varieties used in facades and flooring (limestone Mohs 3–4, typically calibrated to 20 mm for interior and 30 mm for exterior applications) are explicitly named in the CPR. Specifiers on EU projects requiring CE marking documentation now need EPDs matched to the specific limestone's origin, density, and surface treatment — a honed limestone from Portugal carries different GWP data than a brushed limestone from China.

What Comes Next

The European Commission's CPR Working Plan for 2026–2029 prioritises development of harmonised standards for individual product families, including natural stone. As those standards are finalised, generic industry EPDs may become insufficient for high-value or public-tender projects — product-specific EPDs linked to individual quarry sources will carry more weight.

On the CBAM front, the December 2025 downstream expansion proposal is under review. If adopted, its implementation timeline would give stone supply chains a preparation window — but contracts signed today for multi-year European hotel and residential projects should include compliance clauses that account for evolving carbon documentation requirements.

For buyers placing orders now, the practical priority is straightforward: request EPD documentation alongside the standard technical data sheet. Suppliers able to provide quarry-level GWP data, DPP-compatible product documentation, and stone-specific EPDs — covering the exact surface finish and application category specified — are materially lower-risk counterparties for EU projects starting from 2026.
