100% silk

To ensure you are purchasing genuine 100% silk, you must focus on the Momme (mm) weight, which indicates the density and quality of the silk; for bedding, 19mm to 25mm is ideal, while for garments, 12mm to 16mm is standard. Always request a Burn Test report—genuine silk burns slowly, smells like burning hair, and leaves a powdery ash. Additionally, verify the Grade of the silk, with 6A Grade being the highest quality in terms of fiber length, strength, and uniformity.

B2B buyers should prioritize suppliers who hold the OEKO-TEX® Standard 100 certification, which guarantees the silk is free from harmful chemicals and safe for skin contact. For organic silk requirements, look for the GOTS (Global Organic Textile Standard). If exporting to the US, ensure compliance with FTC labeling requirements, which mandate the disclosure of fiber content and country of origin, and check for flammability testing (16 CFR Part 1610) for apparel.

Confirm the weave type, such as Charmeuse for a high-luster finish, Habotai for linings, or Chiffon for transparency. Inquire about the dyeing process—specifically if they use reactive dyes for better colorfastness (Grade 4 or higher). For high-end brands, ask about sand-washing or anti-static treatments to improve the hand-feel and functionality of the finished fabric.

Silk is a high-value commodity with fluctuating prices; therefore, it is wise to lock in prices during the cocoon harvest seasons (typically spring and autumn). Negotiate tiered pricing based on volume, as orders exceeding 500-1,000 meters often qualify for a 10-15% discount. To reduce costs without sacrificing quality, consider silk blends (e.g., silk-cotton) for non-premium lines, but ensure the labeling remains transparent.

The biggest risk is material substitution (e.g., polyester satin passed off as silk). Mitigate this by using Third-Party Inspection services like SGS or Intertek to perform fiber analysis before final payment. Another risk is moisture damage during sea freight; ensure the supplier uses vacuum packaging or moisture-proof PE bags with desiccant packs to prevent mildew.

Focus negotiations on MOQ (Minimum Order Quantity) for custom colors; many suppliers require 100-300 meters per color, but you can negotiate lower MOQs if you use stock colors. Always clarify the Incoterms—FOB (Free On Board) is generally preferred for silk to give the buyer control over shipping costs and insurance for these high-value goods.

For initial orders, utilize Trade Assurance or Letters of Credit (L/C) to ensure payment is only released upon proof of shipment. Avoid direct wire transfers to private accounts. When sourcing through Made-in-China.com, prioritize Audited Suppliers who have undergone on-site verification of their manufacturing capabilities and financial standing.

Due to its high value-to-weight ratio, Air Freight is often the most secure and efficient method for silk garments to prevent prolonged exposure to humidity. If using Sea Freight, ensure the containers are top-tier and leak-proof. Always purchase Marine Cargo Insurance covering 110% of the CIF value to protect against loss or damage during transit.
