Silk pillowcase

The primary quality indicator is Momme weight (mm), which measures silk density. For premium bedding, a range of 19mm to 25mm is standard; 22mm is often considered the 'sweet spot' for durability and luxury. Additionally, ensure the material is 100% Grade 6A Mulberry Silk, which represents the highest long-strand fiber quality. Always verify the weave type, with Charmeuse being the most popular for its high luster and smooth surface.

To ensure consumer safety and market access, products must hold the OEKO-TEX® Standard 100 certification, which guarantees the silk is free from harmful chemicals. For organic claims, look for GOTS (Global Organic Textile Standard). If exporting to the US, compliance with FTC textile labeling requirements (fiber content and country of origin) and flammability standards (16 CFR Part 1610) is mandatory.

Contracts should explicitly state the Momme weight, silk grade (e.g., 6A), and closure type (hidden zipper vs. envelope closure). Specify piping or stitching details (e.g., 13-15 stitches per inch) to ensure seam strength. It is also vital to define colorfastness requirements (Grade 4 or higher) to prevent bleeding during washing, and shrinkage limits (typically <3%).

Maximize value by negotiating tiered pricing; bulk discounts often trigger at 500 or 1,000 units. Consider unbranded 'white label' stock for lower MOQs, or customized packaging (gift boxes vs. polybags) to adjust the final landed cost. Sourcing from integrated manufacturers on Made-in-China.com who handle both weaving and sewing can reduce middleman markups by 15-20%.

The biggest risk is material substitution (e.g., satin/polyester blends passed off as real silk). Mitigate this by requesting third-party lab tests (SGS or Intertek) for fiber composition. Use Trade Assurance or secure payment terms to protect your funds until the Pre-Shipment Inspection (PSI) is passed. Never skip the sample approval stage before starting mass production.

Focus on long-term partnership potential rather than just the lowest price. Inquire about customization capabilities like embroidery or digital printing. Negotiate lead times clearly, especially during peak seasons like Q4. Ask for spare units (1-2%) to be included in bulk shipments to cover any minor manufacturing defects found during local fulfillment.

Silk is lightweight but high-value, making Air Freight or Express (DHL/FedEx) the preferred choice for smaller batches to ensure fast turnover and safety. For large sea freight orders, ensure the use of desiccants and moisture-proof inner packaging to prevent mildew during transit. Always clarify the Incoterms (e.g., FOB or DDP) to understand exactly when the risk of loss transfers from the supplier to you.
