<h1>Manufacturer must substantiate UV-coated PVC 'marble' claims with objective tests, certifications, warranties, and clear installation guidance</h1> A manufacturer has promoted UV-coated PVC 'marble' sheets asserting aesthetic parity with natural marble and claims of long-lasting UV, scratch, water, termite and fire resistance, bendability, low maintenance and environmental benefits from reduced natural marble use. Legally, these marketing claims may trigger consumer protection and advertising law scrutiny; they should be substantiated by objective test data and certifications (e.g., fire safety, durability, VOC emissions) and comply with building codes and labeling rules. Warranties, installation guidance and IP rights should be clear to limit product liability and contractor/distributor exposure. Buyers and regulators will likely seek documented performance evidence and compliance certificates.
