Mobile screen protector

Tempered glass offers superior 9H hardness, providing the best protection against scratches and high-impact drops, while maintaining a crystal-clear transparency similar to the original screen. TPU (Thermoplastic Polyurethane) is a flexible, plastic-like material that is better for curved-edge devices due to its elasticity and self-healing properties for minor scratches, though it offers less impact resistance than glass.

Buyers should prioritize Oleophobic Coating to reduce fingerprints and oil smudges. For high-end markets, look for 2.5D or 3D curved edges to ensure a seamless fit. Additionally, verify the light transmittance rate, which should be above 92% to ensure display clarity, and check for bubble-free adhesive technology (such as AB glue) for easy installation.

Ensure the products comply with RoHS (Restriction of Hazardous Substances) to certify that the materials are free from toxic chemicals. For the EU market, REACH compliance is often required. If the product includes cleaning kits with liquid solutions, ensure they have a Material Safety Data Sheet (MSDS) for safe international transport.

Request a pencil hardness test report or a drop ball test (e.g., a 64g steel ball dropped from 1 meter). A reputable supplier on Made-in-China.com should be able to provide video proof of these tests or third-party lab certifications to validate that the glass will not shatter easily under pressure.

The biggest risk is breakage during transit due to the fragile nature of tempered glass. To mitigate this, insist on reinforced outer packaging and individual retail packaging. Another risk is model mismatch; always verify the exact dimensions and sensor cutout positions for specific phone models (e.g., iPhone 15 vs. 15 Pro) before mass production.

Negotiate based on volume tiers; screen protectors are high-volume, low-margin goods where a 10,000+ unit order can significantly reduce the unit price. Ask for free samples to test the adhesive quality and fit. On Made-in-China.com, look for Audited Suppliers to ensure you are dealing with a factory rather than a middleman to secure better pricing.

Due to the high value-to-weight ratio, Air Freight or Express (DHL/FedEx/UPS) is common for small to medium batches to ensure fast turnover. For large-scale wholesale, Sea Freight is the most economical, but you must ensure the pallets are moisture-proof and clearly labeled as 'Fragile' to prevent heavy stacking.

Always use secure payment terms such as Letters of Credit (L/C) for large orders or trade escrow services provided by Made-in-China.com. Avoid direct wire transfers to unverified personal accounts. Conduct a pre-shipment inspection via a third-party agency to verify the quantity and quality match the Proforma Invoice (PI).
