stock wool fabric

When purchasing stock wool, the primary focus should be on storage conditions and fiber integrity. You must verify the wool content percentage (e.g., 100% wool, 70/30 blend) through a burn test or lab report. Check for signs of aging such as moth damage, 'shelf-smell,' or color fading along the creases. High-quality stock should maintain a soft hand-feel and natural elasticity; if the fabric feels brittle, it may have been stored in a low-humidity environment for too long, compromising its durability.

Key metrics include fabric weight (GSM - Grams per Square Meter) and yarn fineness (Super S numbers like Super 100s or 120s). For suiting, a weight of 240-280 GSM is standard, while coating requires 400+ GSM. Ensure the effective width is consistent across all rolls to avoid layout issues during cutting. Additionally, confirm the shrinkage rate; since stock fabric has often 'settled,' it may have better dimensional stability, but a pre-wash or steam test is still mandatory before bulk cutting.

To ensure market access and consumer safety, prioritize fabrics that meet OEKO-TEX® Standard 100 for absence of harmful substances. If the stock is marketed as sustainable, look for RWS (Responsible Wool Standard) or GOTS (Global Organic Textile Standard) certifications. For the US market, ensure compliance with AATCC standards for colorfastness to light and crocking, and for the EU, ensure the dyes used are REACH compliant.

Stock lots are typically one-off opportunities. It is nearly impossible to find an exact dye-lot match once the current stock is depleted. Buyers should purchase 10-15% more than the calculated requirement to account for potential defects or future repairs. Always request a shipping sample (top sample) from the actual stock rolls being shipped, rather than a generic swatch book, to verify the current color state.

The biggest risk is hidden defects such as holes, stains, or uneven dyeing that are not visible in photos. Unlike fresh orders, stock is often sold 'as-is.' To mitigate this, use a third-party inspection service to perform a 10% random roll check. Ensure the transaction is protected by Trade Terms on Made-in-China.com to secure your payment until the goods are verified.

Stock lots are 'dead capital' for suppliers, giving you significant bargaining power. Negotiate based on volume and 'take-all' strategies; buying the entire remaining lot can often result in a 30-50% discount compared to fresh production prices. Always clarify if the price is FOB (Free On Board) or EXW (Ex Works), as wool is heavy and shipping costs will significantly impact your landed cost.

Wool is highly susceptible to moisture and mildew during sea transit. Insist that the supplier uses double-layer packaging: an inner plastic polybag and an outer woven bag or strong carton. Request desiccant silica gel packs inside the containers. For shipping to humid regions, ensure the container is seaworthy and free of leaks to prevent 'container rain' from damaging the natural fibers.

Focus on suppliers with 'Audited Supplier' status on Made-in-China.com. Check their business track record—specialized stock-lot dealers are often more reliable than factories trying to offload rejected custom orders. Ask for video verification of the warehouse to confirm the stock actually exists and is stored in a clean, temperature-controlled environment.
