wholesale silk fabric

The primary metric for silk quality is Momme (mm) weight; for bedding, 19mm to 25mm is standard, while lightweight scarves may use 8mm to 12mm. You must also verify the Grade (6A being the highest), which indicates fiber length and uniformity. Always request a burn test result or a third-party lab report to ensure the fabric is 100% Mulberry silk and not a synthetic polyester blend.

Suppliers should provide OEKO-TEX® Standard 100 certification to guarantee the fabric is free from harmful chemicals. For the US market, compliance with CFR Part 1610 (Flammability of Clothing Textiles) is mandatory. If you are marketing 'organic' silk, ensure the supplier holds a valid GOTS (Global Organic Textile Standard) certificate.

Confirm the fabric width (usually 114cm, 140cm, or 280cm for bedding) and the dyeing method. For high-end brands, specify reactive dyeing for better colorfastness (Grade 4 or higher). Additionally, inquire about the shrinkage rate, which should typically be controlled within 3-5% through pre-shrinking processes.

Silk prices are tied to global raw silk commodity rates. To save costs, consider purchasing greige fabric (undyed) in bulk and dyeing it locally, or negotiate tiered pricing where a 30% increase in volume can often yield a 5-10% unit price discount. Always clarify if the price is FOB (Free On Board) to avoid unexpected logistics surcharges.

The biggest risk is material substitution, where silk is blended with rayon or polyester. To mitigate this, use Trade Assurance services and hire a third-party inspection agency like SGS or Intertek to perform a fiber content analysis before the final balance payment is made.

Silk is highly sensitive to moisture and pressure. Ensure the supplier uses PVC waterproof inner bags and hard cardboard tubes to prevent creasing. For shipping to distant markets, specify sea-freight with moisture-absorbent packets or air-freight for high-value Grade 6A silk to minimize transit time and environmental exposure.

Focus on consistency of dye lots. Negotiate a clause that ensures color variance (Delta E) remains within a specific range across different batches. For established buyers, request flexible MOQ (Minimum Order Quantity) for seasonal colors in exchange for a guaranteed annual purchase volume.

Conduct due diligence by checking the supplier's Business License and Export Qualification on Made-in-China.com. Prioritize Audited Suppliers who have undergone on-site factory inspections. Always use secure payment channels and avoid direct wire transfers to private accounts.
