Screen guard

Screen guards primarily come in three materials: Tempered Glass, TPU (Thermoplastic Polyurethane), and PET (Polyethylene Terephthalate). Tempered Glass is the industry standard for B2B sourcing due to its 9H hardness, superior scratch resistance, and impact protection. TPU is preferred for curved screens because of its 'self-healing' properties and flexibility, while PET is a budget-friendly option offering basic scratch protection but lower impact resistance.

Focus on Oleophobic Coating, which ensures fingerprint resistance and smooth touch sensitivity. For clarity, ensure a transparency rating of ≥99% to maintain original display quality. Additionally, check for 2.5D or 3D curved edge processing, which prevents edge chipping and provides a seamless fit with the device chassis.

Request RoHS and REACH certifications to ensure the adhesives and coatings are free from hazardous substances. For functional claims, ask for Drop Test Reports (e.g., 1.5m ball drop test) and Hardness Verification from third-party labs. Professional suppliers on Made-in-China.com often hold ISO 9001 certification, ensuring consistent mass production quality.

The market is shifting toward specialized functions such as Anti-Blue Light filters for eye protection, Privacy Filters (28° or 30° viewing angles) for data security, and Matte/Anti-Glare finishes for mobile gamers. Auto-alignment installation kits are also a major trend, significantly reducing the difficulty of application for end-users.

The primary risk is breakage during transit, especially for tempered glass. Ensure the supplier uses reinforced inner packaging (retail boxes or foam crates) and high-quality outer master cartons. Another risk is model mismatch; always verify the precise dimensions and cutout positions for specific regional phone models before finalizing the order.

Since screen guards are high-volume items, negotiate based on tiered pricing. Ask for free samples to test adhesive quality and fit. For long-term partnerships, request customized OEM packaging (private labeling) at lower volume thresholds, and aim for Net 30 payment terms once a trust baseline is established through platforms like Made-in-China.com.

Screen guards are lightweight but fragile. For small to medium batches, Air Express (DHL/FedEx/UPS) is efficient but costly. For bulk orders, Sea Freight or Rail Freight is significantly more economical. To optimize costs, use FOB (Free On Board) terms to maintain control over your logistics provider and ensure the volumetric weight is minimized through compact packaging.

Always conduct transactions through secure payment channels provided by reputable platforms like Made-in-China.com. Utilize Audit Reports to verify the supplier's factory scale and production capacity. Never transfer full payments upfront; a 30% deposit and 70% balance after pre-shipment inspection is the standard professional practice.
