Silk duvet cover

The primary quality indicator is Momme weight (mm). For duvet covers, a range of 19mm to 25mm is ideal; anything below 19mm is too fragile for bedding. Additionally, ensure the silk is Grade 6A, which represents the highest quality long-fiber mulberry silk with the least amount of impurities and the highest tensile strength.

Suppliers must provide OEKO-TEX® Standard 100 certification to guarantee the product is free from harmful chemicals. For the US market, compliance with 16 CFR Part 1610 (Standard for the Flammability of Clothing Textiles) is necessary, while EU buyers should verify REACH compliance for dye safety.

Prioritize covers with seamless construction (wide-width fabric) to avoid uncomfortable seams. Check for internal corner ties to prevent the duvet from shifting and hidden zipper closures or deep envelope closures. The stitching should be high-density, typically 10-12 stitches per inch, to prevent fraying at the seams.

Request a Burn Test report or a third-party fiber composition analysis (e.g., SGS or Intertek). Pure silk will smell like burnt hair and leave a crushable black ash, whereas polyester blends will smell like burning plastic and form a hard, melted bead.

The most significant risk is material substitution, where suppliers blend silk with rayon or polyester to lower costs. To mitigate this, use Made-in-China.com's Secured Trading services and insist on a Pre-shipment Inspection (PSI) to verify the Momme weight and fabric grade before the final payment is released.

Silk prices are tied to global raw silk commodity indices. Negotiate based on volume-tiered pricing; for example, a 500-unit order should yield a 15-20% discount compared to a 50-unit order. If you require custom colors (Pantone matching), expect a higher MOQ of at least 100-200 units per color due to dyeing vat minimums.

Silk is highly sensitive to moisture and odors. Ensure the supplier uses moisture-proof PE inner bags and sturdy, double-walled corrugated outer cartons. For high-end retail, request luxury gift boxes, but ensure they are flat-packed during transit to reduce volumetric shipping weight and costs.

Check the HS Code (typically 6302.21) for specific import duties in your country. Be aware of Anti-Dumping Duties that may apply to certain textile categories. Always request a Certificate of Origin from your supplier to potentially benefit from preferential tariff rates under Free Trade Agreements (FTAs).
