Color slipper

For the upper materials, you should choose between EVA (Ethylene Vinyl Acetate) for lightweight waterproof needs, PVC for cost-effectiveness, or Coral Fleece/Velvet for indoor winter comfort. Ensure the sole thickness is at least 1.5cm to 2cm to provide adequate cushioning. For eco-conscious markets, prioritize recycled polyester or biodegradable EVA to meet sustainability trends.

Request ISO 105-X12 testing reports to verify color fastness to rubbing, ensuring the vibrant colors do not bleed onto skin or carpets. Crucially, for EU and US markets, ensure the products are Azo-free and comply with REACH (EU) or CPSIA (US) standards regarding heavy metals and phthalates in pigments.

The outsole must feature a deep-tread pattern or suction cup design to achieve a high Coefficient of Friction (CoF), especially for bathroom or poolside use. Look for ergonomic arch support and rebound resilience (shore hardness of 35-45HA) to ensure long-term walking comfort without permanent deformation.

Most professional suppliers on Made-in-China.com offer silk-screen printing, heat transfer printing, or PVC patch labeling for branding. For unique shapes, custom mold opening is available, though it typically requires a higher MOQ of 2,000 to 3,000 pairs per design.

Always request a Pre-Production Sample (PPS) before the mass run. Hire a third-party inspection service (like V-Trust or SGS) to perform a During Production Check (DUPRO) and a Final Random Inspection (FRI), focusing specifically on glue overflow, asymmetrical sizing, and odor levels.

Since slippers are lightweight but bulky, they are high-volume cargo. Sea Freight (FCL - Full Container Load) is the most economical. To optimize costs, ask the supplier to use compression packaging or bulk packing (polybags instead of boxes) to reduce the total CBM (Cubic Meters) by up to 40%.

Utilize Secured Trading Services provided by Made-in-China.com to protect your funds. A standard professional payment structure is 30% deposit via T/T to start production and the 70% balance payable against the Bill of Lading (B/L) copy after quality inspection approval.

Check the specific HS Code (typically 6402 or 6405) for your country to identify Anti-Dumping Duties. For example, certain footwear from specific regions may face higher tariffs in the EU or USA. Ensure the supplier provides a Certificate of Origin (Form A or Form E) to help you benefit from preferential tariff rates.
