In 2026, multiple mandatory national standards and industry norms for natural stone will be implemented, covering all 9 types of decorative stone materials including marble, granite, limestone, limestone, sandstone, slate, agate, quartzite, and dolomite. From classification definition, safety and radioactivity, weather resistance, construction protection, application scenarios, and mining environmental protection, the stone industry will officially bid farewell to the era of extensive chaos and enter a new stage of green, standardized, and high-quality development.
The national standard clearly divides 9 types of stone materials according to their geological properties: carbonate materials (marble, limestone, limestone, dolomite) share the common characteristics of not being acid resistant, having a soft texture, and being aesthetically pleasing indoors; Granite is an acidic magmatic rock, which has the best all-around weather resistance outdoors; Quartz minerals (quartzite, onyx) have high hardness, acid and alkali resistance, and high-end luster; Sedimentary metamorphic rocks (sandstone, slate) focus on natural anti slip retro style. Simultaneously clarify the complete ranking of hardness, weathering resistance, aesthetic grade, and price grade, and provide a unified selection principle: granite, slate, and sandstone are given priority for outdoor exterior wall squares; Indoor high-end light luxury prioritizes marble, onyx, and quartzite; Affordable indoor alternative to dolomite; European style warm toned wall with limestone; Chinese antique relief selected sandstone; Choose slate for anti slip in the bathroom; Economic large-scale tooling selection of limestone; Priority should be given to granite quartzite for kitchen oily countertops, and it is strictly prohibited to use carbonate stone for kitchen and outdoor use.
The country has simultaneously introduced ecological and environmental protection policies for mines, and will no longer approve stone mining projects without tailings treatment facilities, and will completely eliminate extensive mining; Starting from August 2026, a mandatory national standard for stone safety will be implemented, strictly regulating safety indicators for radioactivity, dry hanging processes, and protective agents; At the same time, adjusting export policies will force industries to eliminate rough processing and shift towards deep processing and upgrading to finished products. All natural stone color differences, mineral spots, and minor cracks are recognized as natural normal properties. Installation must be reinforced with a back mesh, and daily neutral cleaning and maintenance are required. Carbonate stone is strictly prohibited from contact with strong acids. This full category policy integration comprehensively guides the green mining, fine processing, standardized application, quality and efficiency improvement of the stone industry, promotes the precise matching of 9 types of stone with different decoration scenarios, and achieves scientific, reasonable and sustainable development.
