China produces approximately 50% of the world's flat glass and is a dominant global supplier of glassware, container glass, architectural glass, and specialty glass products. Shandong province produces the majority of China's flat glass (window glass, tempered glass, insulating glass units). Guangdong and Jiangsu are key hubs for decorative glassware and specialty glass products. Chinese glass manufacturers serve construction, home goods, food and beverage, and industrial markets worldwide.

Frequently Asked Questions
Tempered glass: heated to 600°C+ then rapidly cooled, creating compressive stress in the surface. 4–5× stronger than annealed glass. When broken, shatters into small blunt pieces (safer). Cannot be cut after tempering. Standard for shower enclosures, vehicle side windows, glass doors. Laminated glass: two or more glass panes bonded with PVB (polyvinyl butyral) or SGP interlayer. When broken, fragments adhere to the interlayer (very safe). Required for windshields, overhead glazing, hurricane-resistant glass. More expensive than tempered. Both are available from Chinese manufacturers with EN 12150 and EN 12543 certifications respectively.
Glass bottle/jar import process: (1) Specify dimensions, wall thickness, neck finish (28mm, 38mm, 63mm — standardized), glass color (clear, amber, green, cobalt blue). (2) For custom molds: $800–$3,000 per mold, owned by you. Standard molds available at no charge. (3) MOQ: standard sizes 5,000–20,000 units, custom shapes with new molds 10,000+ units. (4) For food contact: verify EU Regulation 10/2011 (migration testing) or FDA compliance. (5) Shipping: glass is fragile and heavy — use specialized packaging (cardboard dividers, foam) and verify palletization before shipment. LCL shipping is common for glass container orders.
Architectural glass for EU market requires: EN 12150-1 (thermally toughened soda-lime glass), EN 14179-1 (heat-strengthened glass), EN 12543-3 (laminated glass), CE marking required for construction products under EU CPR (Construction Products Regulation 305/2011). Energy performance: insulated glass units must meet EN 1279 standards. Solar control glass: EN 410 for solar characteristics. Tempered and laminated glass for façades also need EN 12210 (wind load) compliance. Chinese architectural glass manufacturers exporting to EU must have their products certified by EU-recognized testing laboratories.
Shandong province produces approximately 30–40% of China's total flat glass output. The Shahe area of Xingtai (Hebei, adjacent to Shandong) is sometimes called 'China's glass city' — it's the world's largest glass trading market. Major Chinese glass producers: CSG (China Southern Glass), Xinyi Glass (Hong Kong listed), Jinjing Group, and dozens of regional manufacturers. Shandong glass is competitively priced for construction projects globally. For large architectural projects, buying from Shandong factories directly (with a sourcing agent) versus trading companies can save 15–25%.
