Wholesale coin manufacturers

Buyers must distinguish between Zinc Alloy, Iron, Brass, and Copper. Zinc Alloy is the most popular for 3D designs due to its high fluidity during injection molding. For high-end commemorative coins, Brass is preferred for its weight and premium feel. Ensure the plating process (e.g., Real Gold, Antique Silver, or Nickel) includes an anti-oxidation coating to prevent tarnishing during long-term storage.

Specify whether you require Soft Enamel (textured feel) or Hard Enamel/Cloisonné (smooth, durable surface). For wholesale orders, request a color matching report using the Pantone Matching System (PMS) to ensure brand consistency. Check for surface leveling and ensure there are no air bubbles or dust particles trapped in the recessed areas of the coin.

If the coins are intended for retail or as promotional gifts for children, they must comply with EN71 (Europe) or CPSIA (USA) standards, specifically regarding lead and cadmium content. Ensure the manufacturer provides SGS or Intertek test reports for the base metals and the electroplating chemicals used.

For unique wholesale needs, consider Laser Engraved Serial Numbers, Glow-in-the-dark Enamel, or 3D High-Relief Die Casting. If the coins are for membership or gaming, verify the RFID/NFC chip integration capabilities to ensure technical compatibility with your scanning systems.

When ordering custom designs, ensure you have the legal right to use the logos or artwork. Professional suppliers on Made-in-China.com often require an Authorization Letter. Conversely, protect your own designs by signing a Non-Disclosure Agreement (NDA) before sharing high-resolution vector files to prevent your molds from being reused for other clients.

The Mold Fee is a significant upfront cost; negotiate for a refund of the mold fee once your cumulative order volume reaches a certain threshold (e.g., 5,000 units). For wholesale pricing, request a tiered quotation (e.g., 500, 1000, 5000 pcs) to see the impact of economies of scale on the unit price.

Coins are dense and heavy, making Sea Freight or Rail Freight more economical than Air Express for large volumes. Ensure the supplier uses reinforced double-wall corrugated cartons and individual polybags to prevent scratching during transit. Clearly define the HS Code (typically 7118.90 or 8306.29) to avoid customs delays and ensure accurate duty calculations.

Always use Secured Payment services provided by reputable platforms like Made-in-China.com. Avoid direct wire transfers to private accounts. Conduct a Pre-Shipment Inspection (PSI) through a third party to verify the weight, quantity, and finish quality before the final balance is paid.
