Jelly cases

Buyers should distinguish between TPU (Thermoplastic Polyurethane) and Liquid Silicone. TPU offers superior impact resistance and transparency, making it ideal for 'clear' jelly cases, though it may yellow over time. Liquid Silicone provides a premium soft-touch matte finish and better heat resistance but is generally more expensive. Ensure the supplier uses Bayer or BASF raw materials to minimize the 'yellowing effect' in transparent models.

Prioritize cases with a raised bezel (0.5mm to 1.2mm) to protect the screen and camera lens. For 'jelly' styles, verify the mold precision; high-quality suppliers use CNC high-precision molds to ensure a 0.1mm tolerance, preventing the case from being too loose. Additionally, check for internal micro-dot patterns which prevent the 'rainbow effect' or 'wet look' caused by the case sticking to the phone's glass back.

For the US and EU markets, products must be RoHS (Restriction of Hazardous Substances) and REACH compliant to ensure they are free from harmful chemicals like phthalates. If the cases are intended for children's accessories, CPSIA certification is required. Always request SGS or Intertek test reports to verify that the pigments used in colored jelly cases are non-toxic and lead-free.

Request Military Grade Drop Test (MIL-STD-810G) certification if marketing 'rugged' protection. For aesthetic longevity, ask for the UV resistance rating (Grade 4-5 is optimal) to ensure the case doesn't discolor under sunlight. For printed jelly cases, verify the use of IMD (In-Mould Decoration) or UV Printing with a scratch-resistant coating to prevent the design from peeling.

Jelly cases have a shelf life regarding clarity. Specify the production date in your contract and include a clause that transparency must meet a specific light transmission percentage (e.g., >92%). Use Made-in-China.com's Secured Trading services to hold payment until a pre-shipment inspection (PSI) confirms the goods are newly manufactured and free from oxidation.

Since jelly cases are lightweight but high-volume, shipping costs can easily exceed product value. For orders over 500kg, Sea Freight (LCL) is most economical. However, for trendy models (e.g., new iPhone launches), use Air Express (DDP) to ensure you hit the market window. Consolidating packaging (shipping cases and retail boxes separately) can reduce volume weight by up to 40%.

Avoid sourcing cases for unreleased phone models based on 'leaked' dimensions unless the supplier offers a fitment guarantee. To protect your own designs, ensure the supplier signs a Non-Disclosure Agreement (NDA). When sourcing from Made-in-China.com, prioritize Audited Suppliers who have verified manufacturing facilities to ensure they aren't just middle-men selling infringing designs.

Standard Jelly Cases usually have an MOQ of 500-1,000 units. To lower this, ask for 'In-Stock' colors where the MOQ might be as low as 50 units. For custom branding, negotiate for laser-engraved logos instead of silk-screen printing for smaller batches, as it eliminates the need for expensive printing plates and offers a more durable, premium finish.
