Silk crepe

When evaluating Silk Crepe, the most critical metric is Momme weight (mm). For standard apparel, a range of 12mm to 16mm is common, while premium heavy crepe (Crepe de Chine) typically exceeds 18mm to 30mm. You must also verify the thread count and twist density, as the characteristic 'pebbly' texture of crepe is achieved through high-twist yarns. Ensure the fabric is 100% Mulberry Silk to guarantee superior luster, strength, and hypoallergenic properties.

To ensure market access and consumer safety, prioritize suppliers with OEKO-TEX® Standard 100 certification, which guarantees the fabric is free from harmful chemicals. For organic claims, look for the Global Organic Textile Standard (GOTS). If you are exporting to the US, ensure compliance with FTC Textile Fiber Rule for accurate labeling, and for the EU, verify adherence to REACH regulations regarding dye toxicity.

Request a Burn Test report or perform one on a sample; genuine silk smells like burning hair and leaves a crushable black ash, whereas polyester smells like burning plastic and leaves a hard bead. Additionally, check the luster; real silk has a multi-dimensional sheen that changes color slightly depending on the angle of light, unlike the uniform metallic shine of synthetics. Always ask for a Third-Party Inspection (TPI) report from agencies like SGS or Intertek to verify fiber content.

For high-end evening wear, prioritize drape and opacity (higher momme). For scarves and lightweight overlays, focus on Silk Georgette variants which offer transparency and breathability. If the silk is intended for digital printing, ensure the supplier uses reactive dyes to maintain the fabric's soft hand-feel while achieving high color fastness (Grade 4 or above).

The biggest risks are material substitution (blending with rayon/polyester) and weight discrepancies. Mitigate this by using Trade Assurance services on platforms like Made-in-China.com to protect your payment. Never pay the full balance until a pre-shipment inspection confirms the Momme weight and yardage match the Proforma Invoice.

Silk prices are tied to the global raw silk commodity index, so prices fluctuate. Negotiate based on volume tiers; for example, ordering over 500 meters usually triggers a 10-15% discount. If you are a startup, look for suppliers on Made-in-China.com that offer 'Ready to Ship' stock colors to bypass high MOQs (Minimum Order Quantities) for custom dyeing.

Silk is highly sensitive to moisture and pressure. Insist that the supplier uses double-layered plastic wrapping and sturdy cardboard tubes to prevent creasing. For international shipping, choose Air Freight for high-value silk to minimize the time spent in humid sea containers, which can lead to mildew or odor issues. Ensure the outer cartons are marked 'Keep Dry' and 'Do Not Pressure'.

Check the Harmonized System (HS) Code (typically starting with 5007 for woven silk) against your country's tariff schedule. Be aware of Anti-Dumping Duties or specific trade agreements (like RCEP or FTA) that might reduce import taxes. Always request a Certificate of Origin (CO) from your supplier to take advantage of preferential tariff rates.
