Wooden Blocks & Natural Construction: 1 product from 1 verified supplier in Yunhe. Wooden blocks and natural construction toys use materials such as pine, beech, or rubberwood, often with water-based paints. Production involves cutting, sanding, painting, and quality checks. Certification scope for this category typically includes EN71 and 7P, which cover material safety and phthalate limits. These certificates are crucial because wooden toys may have splinters or paint issues. For minimum order quantity, clarify whether it applies per shape or per set, and confirm packing details such as cotton bags or cardboard boxes. Factories in Yunhe specialize in these items, so buyers should ask about wood moisture content and age grading. Also verify whether custom shapes are possible.
