Polyester mesh net

Buyers should focus on GSM (Grams per Square Meter), which determines the fabric's density and strength; typically, 40-150 GSM is standard for most applications. The mesh size (hole shape and diameter) is critical—hexagonal or diamond shapes offer different levels of elasticity. Additionally, ensure the material is 100% high-tenacity polyester to guarantee resistance to stretching and shrinking.

For textile products, OEKO-TEX® Standard 100 is essential to ensure the mesh is free from harmful substances. If the net is used for outdoor or industrial safety, verify UV resistance ratings (UPF) and ISO 9001 quality management certification. For U.S. markets, compliance with CPAI-84 for flame retardancy may be required depending on the end-use scenario.

For apparel and sportswear, prioritize moisture-wicking finishes and a soft hand-feel. For industrial or filtration use, focus on bursting strength (measured in kPa) and chemical resistance. If the product is for outdoor gear (like tents or mosquito nets), a high hole density (e.g., 250-400 holes per square inch) is vital to prevent insect penetration while maintaining airflow.

Request a pre-production sample (PPS) to test for colorfastness to washing and light (Grade 4 or higher). Conduct a tensile strength test to ensure the mesh can handle the intended load. It is also recommended to verify the shrinkage rate, which should ideally be less than 3% under standard washing conditions.

Utilize secure payment terms such as Letter of Credit (L/C) or platforms that offer Trade Assurance services. Always conduct third-party factory audits via agencies like SGS or Intertek to verify the supplier's production capacity and legitimacy. For sourcing in China, Made-in-China.com provides verified supplier profiles that help reduce the risk of dealing with non-existent entities.

Polyester mesh is a volume-driven commodity. You can often achieve a 10-20% price reduction by increasing the order to meet the supplier's dyeing vat capacity (usually around 500-1,000kg). Negotiate for tiered pricing based on annual volume rather than single orders, and ask for free lab dips to ensure color accuracy before committing to a large deposit.

Since mesh is lightweight but bulky, it is often charged by volumetric weight. Request vacuum packaging or high-compression rolling to reduce the volume and save on ocean freight costs. Ensure the outer cartons are waterproofed with plastic lining to prevent mold or moisture damage during long-transit sea voyages.

Check the HS Code (typically 6005.37 for synthetic warp knit fabrics) against your country's tariff schedule to account for Anti-Dumping Duties (ADD) or specific trade barriers. Ensure the supplier provides a Certificate of Origin (CO), which may qualify the shipment for Preferential Tariff Rates under Free Trade Agreements (FTAs).
