      To purchase authentic Chinese silk products and avoid counterfeit items, follow these key guidelines based on industry standards and expert recommendations:

      1. Verify Product Labels & Certifications

      • Check “SILK100%” Label: Authentic silk products must clearly specify composition (e.g., “100% mulberry silk” / “100% 桑蚕丝”). Avoid vague terms like “silk blend” without exact percentages.
      • 5-Digit Fabric Codes: In China, genuine silk fabrics use a standardized 5-digit code starting with “1” (e.g., “10001” for pure mulberry silk). Codes starting with “2”/”3″ indicate synthetic blends (e.g., polyester-silk mixes).
      • Third-Party Certifications: Reputable brands provide lab reports from institutions like PONY Testing, verifying fiber content, colorfastness, and safety standards. Always request these documents for high-value purchases.

      2. Physical Inspection: The “5-Step Test”

      Use these tactile and sensory checks to distinguish real silk:
      1. Luster (光泽):
        • Authentic: Soft, pearlescent sheen that changes with light angles, avoiding harsh or plastic-like gloss.
        • Fake: Excessively shiny or flat appearance, similar to polyester.
      1. Texture (手感):
        • Authentic: Cool to the touch, smooth with slight elasticity; wrinkles easily when pinched and retains creases.
        • Fake: Stiff, slippery, or overly smooth, with minimal wrinkle resistance.
      1. Burn Test (燃烧测试):
        • Authentic: Burns slowly, emits a smell of burnt hair, and leaves soft, crumbly ash.
        • Fake (Polyester): Melts into hard, black beads with a sweet, chemical odor.
      1. Wet Stretch Test (湿润拉伸):
        • Authentic: Wet silk fibers stretch unevenly and break with frayed, fibrous ends.
        • Fake: Snaps cleanly when wet, showing no fraying.
      1. Bleach Dissolve Test (漂白溶解):
        • Authentic: Dissolves completely in “84 消毒液” (sodium hypochlorite bleach), leaving no residue.
        • Fake: Remains intact or partially dissolves, leaving plastic-like fragments.

      3. Choose Trusted Purchase Channels

      • Brick-and-Mortar Stores:
        • Opt for established brands like Xiangrun Silk (祥润绸庄) in Hangzhou, specializing in heritage textiles like Xiangyunsha (香云纱), an intangible cultural heritage gambiered silk.
        • Visit silk hubs: Suzhou (丝绸之乡) and Nanjing for direct access to workshops and certified retailers.
      • E-Commerce Platforms:
        • On Taobao/JD.com, filter for stores with “老字号” (time-honored brand) badges or official flagship store certifications.
        • Avoid listings with prices below ¥200 for scarves or ¥1,000 for dresses—genuine silk costs 2–3x more than synthetic alternatives.
      • Wholesale/Bulk Orders:
        • Partner with suppliers on Alibaba.com that display ISO 9001 or OEKO-TEX Standard 100 certifications for quality assurance.

      4. Advanced Anti-Counterfeit Features

      High-end silk products may include:
      • UV-Reactive Labels: Laser-engraved logos or fluorescent dyes visible under ultraviolet light (refer to patent CN103469626B for technical details).
      • QR Code Traceability: Scan codes to verify production origins, such as mulberry farm locations or weaving mill certifications.

      5. Care Instructions as Quality Clues

      • Washing Guidance:
        • Authentic silk: Requires gentle hand-washing in cold water with neutral detergent; avoid machine washing or tumble drying.
        • Fake silk: Often claims to be machine-washable, a red flag for synthetic blends.
      • Packaging & Documentation:
        • Genuine products include detailed care manuals, fabric composition tags, and branded packaging (e.g., silk dust bags for garments).
      Critical Tip: Always request a physical swatch sample for burn/dissolve testing before committing to large orders. For professional verification, contact institutions like the National Silk Quality Inspection Center or local textile associations.
      By combining label checks, hands-on testing, and trusted sourcing, you can confidently invest in authentic Chinese silk while avoiding counterfeits. Prioritize transparency and documentation—reputable sellers will readily provide certification and testing support.
