100% cotton

To ensure authenticity, buyers should request a Third-Party Lab Test Report (SGS, ITS, or TUV) specifically for Fiber Content Analysis. A common field test is the Burn Test: 100% cotton should smell like burning paper, leave a fine grey ash, and not melt or bead like synthetic blends. Additionally, check for the Cotton USA™ or Global Organic Textile Standard (GOTS) certification to guarantee purity and ethical sourcing.

Key metrics include Thread Count (TC) for beddings or Grams per Square Meter (GSM) for apparel; higher GSM usually indicates a thicker, more durable fabric. Pay close attention to Yarn Count (e.g., 30s, 40s, 60s)—higher numbers signify finer, softer yarns. For industrial or retail use, verify the Color Fastness Grade (Grade 4 or above is recommended) and the Shrinkage Rate, which for 100% cotton should ideally be controlled within ±3% to 5% through pre-shrinking processes.

For the US market, products must comply with CPSIA (especially for children's wear) and ACT (Association for Contract Textiles) standards. For the EU, REACH regulations regarding chemical dyes are mandatory. OEKO-TEX® Standard 100 is a globally recognized benchmark ensuring the cotton is free from harmful substances, which is a significant selling point for B2B buyers focusing on health-conscious consumers.

The price varies significantly based on the staple length. Extra-Long Staple (ELS) cotton, such as Pima or Egyptian cotton, commands a premium price but offers superior softness and strength. For mass-market retail, Upland cotton is more cost-effective. Buyers should balance the Target Retail Price with the material grade, noting that Organic Cotton typically carries a 15-25% price premium due to certification and specialized farming costs.

The primary risk is Material Substitution, where suppliers blend cotton with polyester to reduce costs. Another risk is Moisture Damage during sea transit, leading to mold. To mitigate this, ensure the contract specifies the use of Silica Gel desiccant packs and PE inner bag packaging. Always use Trade Assurance on platforms like Made-in-China.com to protect your payment until quality is verified.

Negotiate based on Volume Tiers; for 100% cotton, price fluctuations are tied to the Global Cotton Commodity Index. Request a Fixed Price Agreement for a set period to avoid sudden surcharges. Additionally, negotiate the MOQ (Minimum Order Quantity) by offering to use 'Greige Fabric' (un-dyed) that the supplier already has in stock, which can significantly lower entry barriers for custom colors.

Cotton is heavy and voluminous. For cost-efficiency, use Sea Freight (FCL or LCL). Ensure the supplier provides a Fumigation Certificate if wooden pallets are used. To prevent 'Container Sweat,' request Vacuum Packaging for finished goods like towels or t-shirts, which reduces volume and protects against humidity and odors during long-distance cross-border shipping.

Conduct a Factory Audit or hire a local inspection service to verify the supplier's production capacity. On Made-in-China.com, prioritize Audited Suppliers who have undergone on-site verification. Ensure all technical specs, including weight tolerance and pilling resistance, are clearly documented in the Proforma Invoice (PI) to provide legal recourse in case of disputes.
