Wholesale natural raw silk

Raw silk is graded according to international standards ranging from 6A (highest quality) to A, B, C, etc. For high-end B2B procurement, you should prioritize Grade 6A or 5A silk, which ensures superior tensile strength, evenness, and minimal exfoliation. Always request a Quality Inspection Report that details the denier (thickness) deviation and cleanness percentage to ensure the silk meets your specific weaving or knitting requirements.

Key specifications include the Momme weight (mm) for finished fabrics or Denier (D) for raw yarn. Common deniers for raw silk are 20/22D or 27/29D. You must also verify the moisture regain rate, which is standard at 11%; excessive moisture can lead to paying for water weight and potential mildew risks during long-distance cross-border transit.

To enter European or North American markets, ensure the supplier holds OEKO-TEX® Standard 100 certification, which guarantees the silk is free from harmful chemicals. For eco-conscious brands, look for GOTS (Global Organic Textile Standard) or GRS (Global Recycled Standard) if applicable. Additionally, verify that the supplier complies with ISO 9001 for quality management systems.

Natural raw silk is highly versatile, used in high-end fashion (bridal wear, evening gowns), home textiles (silk bedding, curtains), and even medical applications (surgical sutures) due to its biocompatibility. In the beauty industry, it is increasingly used for silk pillowcases and eye masks to reduce friction and retain skin moisture.

The primary risks include material substitution (blending with polyester) and weight discrepancies. To mitigate these, always use Made-in-China.com's Secured Trading services and hire a third-party inspection agency (like SGS or Intertek) to perform a burn test or chemical solubility test before the final balance payment is made.

Silk is a commodity with prices fluctuating based on cocoon market trends. It is advisable to negotiate tiered pricing based on volume. For initial orders, seek a lower MOQ (e.g., 5-10kg) for sampling, but aim for bulk discounts of 10-15% when ordering over 500kg. Always clarify if the quoted price is FOB (Free On Board) to avoid hidden logistics costs.

Silk is sensitive to humidity and light. Ensure the supplier uses vacuum-sealed plastic inner packaging and sturdy corrugated outer boxes. For shipping to distant regions, Sea-Air combined transport or Express (DHL/FedEx) is recommended for smaller high-value batches to minimize exposure to harsh port conditions. Ensure the containers are kept in a cool, dry environment to prevent fiber degradation.

Check the HS Code (typically 5002.00) for raw silk in your country to determine import tariffs and VAT. Be aware of any anti-dumping duties or specific Certificate of Origin requirements (like Form E or CO) that could provide preferential tariff treatment under free trade agreements.
