Chiffon silk

The most reliable method is the Burn Test. Genuine silk chiffon will smell like burning hair, produce a brittle black ash that crushes easily, and stop burning immediately when the flame is removed. Synthetic chiffon smells like burning plastic, produces a hard black bead, and continues to melt. Additionally, check the Momme (mm) weight; high-quality silk chiffon typically ranges from 6mm to 12mm.

Focus on fabric density and weave uniformity. Ensure the twist of the yarns is consistent to provide that characteristic 'crepe' texture without snagging. For dyed or printed silks, verify Color Fastness (Grade 4 or higher) to prevent bleeding. Always request OEKO-TEX Standard 100 certification to ensure the fabric is free from harmful chemicals, which is a critical requirement for the European and North American markets.

For Evening Wear and Bridal, prioritize transparency levels and drape. For Scarves and Accessories, focus on hand-feel (softness) and edge-rolling compatibility. If the silk is intended for Digital Printing, ensure the fabric has been pre-treated to absorb reactive dyes effectively, ensuring vibrant colors and sharp patterns.

Momme (mm) measures the weight per unit area. 6mm-8mm is ultra-light and sheer, ideal for layering or light scarves, and is generally more affordable. 10mm-12mm is more durable, less transparent, and preferred for high-end garments, commanding a higher price point. Buyers should match the Momme weight strictly to the garment's structural needs to balance cost-efficiency and quality.

Always use Third-Party Inspection services (like SGS or Intertek) to conduct a Fiber Content Analysis before the final balance payment. Clearly state in the Proforma Invoice (PI) that the material must be 100% Mulberry Silk. On Made-in-China.com, prioritize Audited Suppliers who have verified production capabilities and material certifications.

Silk is highly sensitive to moisture and pressure. Ensure the supplier uses double-layer packaging: an inner moisture-proof PE bag and a sturdy outer carton or wooden crate. Request that rolls are not stacked too high to prevent permanent creasing of the delicate fibers. For high-value silk, Air Freight is recommended over Sea Freight to minimize exposure to humidity and long-term compression.

Negotiate based on Total Volume rather than a single order. If you are a recurring buyer, ask for a 5-10% discount on repeat patterns or colors. For custom-dyed silk, discuss Lab Dip costs upfront; many top-tier suppliers will waive the Lab Dip fee if the bulk order exceeds 500 meters.

Utilize Trade Assurance or Letters of Credit (L/C) for large-scale transactions to ensure funds are only released upon proof of shipment and quality compliance. Avoid direct wire transfers to private accounts. Ensure all Incoterms (e.g., FOB, CIF) are clearly defined to establish where the risk transfers from the seller to the buyer.
