Canton fair pu bags

When sourcing PU (Polyurethane) bags, prioritize Waterborne PU or Microfiber PU for superior durability and eco-friendliness. Ensure the material thickness is at least 1.0mm to 1.2mm to prevent peeling and cracking. For the lining, high-density polyester (210D or higher) or cotton twill is recommended to ensure internal tear resistance.

For the EU market, products must comply with REACH regulations, specifically testing for phthalates, lead, and cadmium content. For the US market, California Proposition 65 and CPSIA (if for children) are critical. Always request SGS or Intertek lab reports to verify that the synthetic materials do not contain harmful Azo dyes.

Examine the stitching density, which should be 7-9 stitches per inch with no loose threads. Hardware (zippers, buckles, hooks) should be made of zinc alloy with electroplating to prevent oxidation; test the zippers for smoothness over 50 cycles. Ensure that edge oiling is smooth, uniform, and does not become tacky in high temperatures.

For Business/Laptop bags, ensure a shockproof foam compartment and reinforced handles. For Fashion handbags, focus on colorfastness (Grade 4 or higher) and trendy hardware finishes. For Travel bags, prioritize load-bearing reinforcement at stress points using 'X' stitching or rivets to handle weights over 10kg.

Implement a Pre-Shipment Inspection (PSI) by a third-party agency. Use the AQL 2.5/4.0 standard to define acceptable quality levels. For secure transactions, utilize Made-in-China.com's Secured Trading Service to ensure payment is only released after the goods pass inspection and shipping documents are verified.

Suppliers often offer a 15-20% discount for orders exceeding 1,000 units. If you are a startup, negotiate a mixed-color MOQ (e.g., 300 units total across 3 colors) to reduce inventory risk. Always ask for FOB (Free On Board) pricing to maintain control over your international logistics costs and choice of freight forwarder.

PU bags are susceptible to mold and humidity during sea freight; insist that the supplier includes silica gel desiccant packets in every polybag and uses moisture-proof inner linings for the master cartons. Ensure the HS Code (typically 420222) is correctly declared to avoid customs delays or incorrect duty applications.

Check if the supplier is an Audited Supplier on Made-in-China.com, which confirms their business license, production capacity, and factory location. Request a video factory tour to see their production lines and check if they have ISO 9001 or BSCI (Business Social Compliance Initiative) certifications to ensure ethical manufacturing.
