Screen protectors

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

For modern smartphones, you must prioritize 0.33mm or 0.26mm thickness to ensure touch sensitivity is not compromised. Additionally, ensure the product features an oleophobic coating to resist fingerprints and oils. For devices with in-display fingerprint sensors, verify that the protector uses high-permeability glue and has been tested for biometric sensor compatibility.

Buyers should ensure products comply with RoHS (Restriction of Hazardous Substances) to guarantee the absence of lead, cadmium, and other heavy metals. For the European market, REACH compliance is essential. If the product includes cleaning kits with alcohol pads, these must have MSDS (Material Safety Data Sheets) for safe international transport and customs clearance.

The quality of the Japanese or Korean AB glue used is vital for a bubble-free installation and long-term adhesion. High-quality glue ensures the protector can be reinstalled if misaligned and leaves no residue upon removal. You should request samples to test for edge lifting after 48 hours of application.

Screen protectors, especially tempered glass, are fragile. You should mandate reinforced outer cartons and individual retail packaging (blister packs or wooden boxes). For bulk shipments, ensure the supplier uses palletization and clearly marks the cargo as 'Fragile'. On Made-in-China.com, you can select Audited Suppliers who have proven experience in export-grade packaging.

Screen protector margins are tight, so focus on volume-based pricing tiers. A typical MOQ for custom (OEM) packaging is 1,000 to 3,000 units, while neutral packaging may have an MOQ as low as 50-100 units. Negotiate for free replacement units (1-2% defect allowance) in every bulk order to cover potential shipping damages or manufacturing flaws.

Always use Secured Payment services provided by platforms like Made-in-China.com to ensure funds are only released upon confirmation of receipt. To maintain quality, hire a third-party inspection service to perform a Pre-Shipment Inspection (PSI), focusing on drop-ball tests, dimension accuracy, and hole alignment for camera and speaker cutouts.

Check the HS Code (typically 7007.19 for tempered glass) to determine import duties in your country. Be aware of anti-dumping duties that some regions may apply to glass products. Ensure the supplier provides a Certificate of Origin to help you benefit from any existing Free Trade Agreements (FTAs) between China and your specific country.
