Women bikini

B2B buyers should prioritize fabrics with a blend of 80-85% Nylon (Polyamide) and 15-20% Spandex (Elastane) for optimal stretch and recovery. Ensure the fabric weight is between 190-220 GSM to prevent transparency when wet. For premium lines, look for Italian Carvico or ECONYL® regenerated nylon, which offer superior durability and sustainability credentials.

To ensure product durability, verify that the materials have High Chlorine Resistance (to prevent fiber breakdown in pools) and UPF 50+ UV Protection. Additionally, the fabric must pass Colorfastness to Sea Water and Perspiration (ISO 105-E02/E04) tests with a rating of Grade 4 or higher to prevent fading and bleeding.

For the US market, products must comply with CPSIA (especially for lead content in metal toggles/rings). For the EU, REACH compliance is mandatory to ensure no harmful azo dyes or phthalates are used. Obtaining the OEKO-TEX® Standard 100 certification is highly recommended as it guarantees the product is safe for direct skin contact.

Inspect for Four-Needle Six-Thread (Flatlock) stitching, which provides maximum seam strength and comfort against the skin. Check that hygienic liners are securely attached and that removable padding is made of quick-dry perforated foam. Ensure all hardware (buckles, rings) is salt-water resistant and nickel-free to avoid oxidation and skin allergies.

Always request a Pre-Production Sample (PPS) for fit and color approval before mass production. Utilize third-party inspection services (like V-Trust or QIMA) to conduct a During Production Check (DUPRO) and a Final Random Inspection (FRI) focusing on sizing consistency, as swimwear sizing charts vary significantly between Asian and Western markets.

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 flexibility, such as custom branded labels and eco-friendly packaging, which adds significant retail value. Ensure the Lead Time is clearly defined, typically 30-45 days for bulk orders, to avoid missing seasonal sales windows.

Use Secured Payment services provided by Made-in-China.com to ensure funds are only released upon proof of shipment. For initial large orders, a payment term of 30% deposit and 70% balance against the Bill of Lading (B/L) is standard. Avoid direct wire transfers to private accounts; always use the verified corporate account listed on the platform.

Given the seasonal nature of bikinis, use Sea-Air combined transport or Express (DHL/FedEx) for small restocks to maintain inventory levels. For bulk shipments, choose FOB (Free On Board) terms to maintain control over freight costs and choose your own forwarder. Ensure the supplier provides a Detailed Packing List and Commercial Invoice with correct HS Codes (typically 6112.41 for synthetic swimwear) to avoid customs delays.
