Case

When sourcing cases, prioritize materials based on the end-use scenario. For high-end mobile cases, TPU (Thermoplastic Polyurethane) offers a balance of flexibility and shock absorption, while PC (Polycarbonate) provides rigid impact resistance. For industrial or rugged use, look for multi-layer construction combining a hard shell with a soft silicone inner sleeve. Ensure the supplier uses non-yellowing agents in transparent cases and verify the Shore Hardness rating to match your protection requirements.

To ensure smooth customs clearance and consumer safety, products must meet regional regulations. For the EU market, RoHS (Restriction of Hazardous Substances) and REACH certifications are mandatory to ensure the absence of toxic chemicals like lead or phthalates. For the US market, ensure compliance with California Proposition 65. If marketing 'military-grade' protection, request test reports for MIL-STD-810G drop-testing standards from third-party labs.

Precision is critical in the case industry. Demand 1:1 real-machine mold opening rather than relying on 3D mockups, which can have slight discrepancies. Check for precise port cutouts, tactile button feedback, and raised bezels (at least 1.0mm) to protect screens and camera lenses. For electronic cases, verify wireless charging compatibility and ensure the material thickness does not interfere with NFC or signal strength.

A top-tier supplier should offer various branding techniques such as IMD (In-Mold Decoration), UV Printing, Silk-screen printing, or Laser Engraving. For ODM projects, confirm they can provide CAD/SolidWorks drawings and 3D printed prototypes within 3-5 days. Evaluate their ability to handle custom packaging, which is vital for retail-ready B2B orders.

The primary risk in the case industry is intellectual property (IP) infringement and mold inaccuracy. Always use Made-in-China.com's 'Audited Supplier' reports to verify the factory's existence and production capacity. Use Trade Settlement services to ensure payments are only released upon proof of shipment. Additionally, perform a Pre-shipment Inspection (PSI) to check for cosmetic defects like burrs, scratches, or color deviations which are common in mass production.

Case production is highly volume-dependent due to injection molding costs. For standard models, aim for a tiered pricing structure where costs drop significantly at 1,000+ units. If you are a startup, negotiate a lower MOQ for trial orders by choosing 'open-mold' (generic) designs before investing in 'private-mold' (exclusive) tooling. Always clarify if the quoted price includes packaging and labeling costs to avoid hidden expenses.

Protective cases are lightweight but high-volume, meaning volumetric weight often exceeds actual weight. For large orders, Sea Freight (LCL or FCL) is the most economical. For urgent stock replenishment of new phone models, use Air Freight or International Express (DHL/FedEx). Ensure the supplier uses double-corrugated export cartons and palletization to prevent crushing during transit. Always confirm the Incoterms (e.g., FOB or DDP) to clearly define who is responsible for import duties and local delivery.
