CD jewel case

The most critical material is High-Quality Polystyrene (PS), which provides the classic crystal-clear transparency. For the internal tray, you can choose between General Purpose Polystyrene (GPPS) for clear trays or High Impact Polystyrene (HIPS) for solid colors like black or white. Ensure the material is virgin grade rather than recycled to avoid yellowing, brittleness, or surface streaks.

Focus on the hinge strength and the center hub (rosette) design. A high-quality case should have a reinforced 'teeth' design on the hub to hold the disc securely without snapping. The hinges should operate smoothly without cracking under pressure. Additionally, check for automated packing compatibility; if you are using high-speed insertion machines, the cases must meet standardized dimensions (142 x 125 x 10.4mm) with minimal tolerance variance.

Products must comply with REACH and RoHS directives to ensure they are free from hazardous substances like lead or phthalates. For the North American market, ensure the materials meet CPSIA standards if the end product is accessible to children. Always request SGS or Intertek test reports from suppliers on Made-in-China.com to verify chemical safety.

Beyond the Standard 10.4mm Jewel Case, you should consider Slimline cases (5.2mm) for space-saving, Double/Multi-disc cases (Chubby cases) for box sets, and Premium 'Super Jewel Box' styles with rounded corners. Selecting the right type depends on your shipping weight constraints and the perceived value of the media content.

CD jewel cases are highly fragile. You must mandate 5-layer corrugated export cartons and the use of corner protectors. For LCL (Less than Container Load) shipments, insist on palletization with shrink wrap to prevent crushing. It is highly recommended to include a 2-3% breakage allowance or 'over-shipment' in the contract to cover potential transit damage.

Due to the high volume-to-weight ratio, Sea Freight (FCL - Full Container Load) is the only economically viable method for large orders. A 40HQ container can significantly reduce the landed cost per unit. If sourcing from Made-in-China.com, negotiate FOB (Free On Board) terms to maintain control over your shipping line and avoid inflated destination charges.

Utilize Secured Trading Services provided by Made-in-China.com to protect your payment until the goods are shipped. Always conduct a Pre-Shipment Inspection (PSI) through a third-party agency to verify the quantity, clarity, and weight of the cases before the final balance is paid.

Focus on mold maintenance and cycle times. Ask the supplier about their mold cavity count; higher cavity molds (e.g., 2+2 or 4+4) offer better price points for massive volumes. Discuss raw material price indexing—since polystyrene prices fluctuate with oil markets, establishing a transparent pricing formula can build a more stable long-term partnership.
