Wholesale postcard manufacturers

Focus on paper weight (GSM) and coating types. For a premium feel, select cardstock between 300gsm and 350gsm. Ensure the supplier offers UV coating or matte lamination on the front for durability, while keeping the back uncoated to allow for easy writing with standard pens.

Request that the supplier uses CMYK 4-color offset printing rather than digital printing for large batches to ensure color consistency. Verify that the resolution is at least 300 DPI and ask for a physical proof (sample) to check for registration errors or color bleeding before authorizing a full production run.

Prioritize suppliers with FSC (Forest Stewardship Council) certification, which guarantees the paper is sourced from responsibly managed forests. For European markets, ensure compliance with REACH regarding non-toxic inks, and for the US, check that the materials meet USPS mailing thickness requirements (minimum 0.007 inches).

Yes, most professional manufacturers on Made-in-China.com support OEM/ODM services. You should look for options like foil stamping, embossing, or die-cutting to differentiate your product. Ensure the supplier can handle variable data printing if you require unique QR codes or serial numbers on each card.

Paper products are highly susceptible to moisture and corner damage. Insist on shrink-wrapping in bundles of 50 or 100 units and the use of double-walled corrugated export cartons. Request silica gel desiccant packets in every master carton to prevent warping during sea freight.

Since postcards are heavy but low-volume, Sea Freight (LCL - Less than Container Load) is usually the most economical for orders over 200kg. For smaller trial orders, International Express (DHL/FedEx) is faster, but you should negotiate DDP (Delivered Duty Paid) terms to avoid unexpected customs clearance hurdles.

Postcard production has high setup costs. To get the best price, consolidate multiple designs into a single order to reach a higher total volume, which can reduce the unit price by 20-40%. Ask for a tiered pricing structure based on 1,000, 5,000, and 10,000 units.

Always use the Secured Trading Service provided by Made-in-China.com to protect your payment. Do not release the final 70% balance until you have received a third-party inspection report or high-resolution photos/videos of the finished goods and packaging.
