Case tpu

When sourcing TPU (Thermoplastic Polyurethane) cases, you must prioritize optical clarity (for transparent models) and yellowing resistance. High-grade TPU should feature UV-resistant additives to prevent discoloration over time. Additionally, check for Shore Hardness (typically 85A to 95A) to ensure a balance between impact absorption and structural rigidity. The presence of a micro-dot pattern on the interior is essential to prevent the 'wet look' or rainbow effects caused by Newton’s rings when the case touches the device back.

For the US market, ensure products are CPSIA compliant regarding lead and phthalate content. For the EU, REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) and RoHS (Restriction of Hazardous Substances) certifications are critical to prove the absence of toxic plasticizers. If you are marketing 'Eco-friendly' TPU, request GRS (Global Recycled Standard) certification to verify the percentage of recycled content.

Request samples to verify 1:1 real machine mold opening. Pay close attention to the button tactile feedback; buttons should be easy to press with clear clicking sensations. Check the port cutouts for sufficient clearance to accommodate third-party charging cables. Furthermore, ensure the raised bezel (lip) is at least 0.8mm to 1.2mm above the screen and camera lens to provide adequate drop protection.

Suppliers on Made-in-China.com typically offer IMD (In-Mold Decoration) for high-quality, scratch-resistant graphics, UV Printing for low-MOQ custom designs, and Silk Screen Printing for simple logos. For premium branding, consider Laser Engraving or Electroplating for a metallic finish on the TPU edges.

TPU has a shelf life; older stock tends to degrade. Include a clause in your contract specifying that the production date must be within the last 3 months. Use Third-Party Inspection services before final payment to conduct a color comparison test against the approved golden sample under standard D65 light sources.

TPU cases are high-volume, low-margin goods. To get the best price, aim for MOQs of 500-1,000 units per model. If you are a startup, negotiate a mixed-model MOQ (e.g., 3,000 units total across 10 different iPhone/Samsung models). Always ask for tiered pricing (1k, 5k, 10k units) to understand the supplier's scalability.

TPU cases are lightweight but bulky when packaged. To optimize costs, consider shipping cases in bulk polybags and flat-packing the retail boxes separately to reduce volumetric weight. For large orders, Sea Freight (LCL) is most economical, but for hot-selling new phone releases, Air Express (DDP) is recommended to capture the market window quickly.

Always utilize the Secured Trading Service on Made-in-China.com to ensure your payment is held in escrow until delivery is confirmed. Prioritize Audited Suppliers who have undergone on-site inspections by independent bodies like SGS or TÜV Rheinland to verify their manufacturing capacity and business legitimacy.
