Leggings

When evaluating leggings, focus on fabric composition, typically a blend of Nylon and Spandex (Elastane) for durability and stretch. For high-performance activewear, a 75% Nylon / 25% Spandex ratio is standard. Ensure the fabric weight is between 220 GSM to 320 GSM to prevent 'see-through' issues (squat-proof). Additionally, look for four-way stretch technology and moisture-wicking finishes to ensure comfort during intense physical activity.

Prioritize suppliers using Flatlock Stitching (6-thread 4-needle), which reduces skin friction and provides maximum seam strength. Check for a gusseted crotch design to prevent tearing and improve range of motion. For waistbands, high-rise double-layered construction with internal elastic or 'tummy control' compression is highly sought after in the current B2B market.

Ensure the products meet OEKO-TEX® Standard 100 to guarantee they are free from harmful chemicals. For the US market, compliance with CPSIA (especially for youth sizes) is mandatory. If you are targeting eco-conscious consumers, verify GRS (Global Recycled Standard) certifications for leggings made from recycled polyester or ocean plastics.

Request a stretch recovery test report to ensure the leggings return to their original shape after use. To verify 'squat-proof' quality, ask for opacity testing under high-intensity light. For 'non-slip' features, check if the supplier offers silicone waist grippers or specialized high-compression knitting at the waistband to prevent rolling during movement.

Size standards vary significantly between Asian, European, and American markets. You must provide a detailed size specification chart in centimeters and request a pre-production sample (PPS). Ensure the contract includes a tolerance clause (typically +/- 1cm to 1.5cm) to hold the manufacturer accountable for deviations.

Focus on tiered pricing based on volume; for example, aim for a 15-20% discount when moving from 500 to 2,000 units. Negotiate for OEM/ODM customization (like private labeling or custom colors) to be included in the unit price for bulk orders. Always verify the supplier's Audit Report on the platform to ensure they are a genuine manufacturer rather than a middleman.

Utilize Secured Trading Services provided by the platform to ensure payment is only released upon confirmation of shipment. Always insist on a Third-Party Pre-shipment Inspection (PSI) to check for fabric defects, loose threads, and color shading (Lab dips) before the final balance is paid.

For small trial orders, International Express (DHL/FedEx) is fastest but expensive. For bulk commercial stock, Sea Freight (LCL or FCL) is the most economical. Given that leggings are high-density but low-volume, consider Matson Fast Boat services for a balance between speed and cost-efficiency when shipping to the US.
