Interlining

Selecting the correct interlining depends on the base fabric weight and the desired structure. For lightweight fabrics like silk or chiffon, use ultra-lightweight non-woven or tricot fusible interlining to maintain drape. For heavy tailored suits or coats, woven haircloth or canvas interlining is essential for crisp structural integrity. Always match the shrinkage rate of the interlining with the outer fabric to prevent bubbling after washing.

Buyers must prioritize coating technology, specifically choosing between Double Dot, Paste Dot, or Powder Dot based on the fabric type. Double Dot is generally preferred for its superior bond strength and resistance to strike-through. Additionally, verify the base material composition (Polyester, Nylon, or Viscose) and the weight (GSM) to ensure it meets your specific stiffness requirements.

Ensure the product carries the OEKO-TEX® Standard 100 certification, which guarantees the interlining is free from harmful substances like formaldehyde—a critical requirement for skin-contact apparel. For the European market, compliance with REACH regulations is mandatory. For children's wear in the US, ensure the adhesive and base materials meet CPSIA standards for lead and phthalate content.

Conduct a Peel Strength Test (measured in N/5cm) both before and after washing to ensure the adhesive remains stable. Perform Dry Cleaning and Home Laundry tests (at least 5-10 cycles) to check for delamination, bubbling, or strike-back. It is also vital to test the fusing conditions (temperature, pressure, and time) using your specific production machinery to ensure compatibility.

The primary risk is quality inconsistency between batches, where the adhesive strength varies. To mitigate this, use Made-in-China.com's Secured Trading services and insist on a Pre-Shipment Inspection (PSI). Another risk is moisture damage during sea freight, which can degrade the adhesive coating; ensure the supplier uses moisture-proof PE bag packaging and desiccant packs inside the export cartons.

Interlining is often produced in large rolls. For custom coatings or colors, MOQs typically range from 1,000 to 3,000 meters. Negotiate for tiered pricing where a 20% increase in volume could yield a 5-10% discount. If you are a startup, look for suppliers on Made-in-China.com that offer stock-supported items with lower MOQs (e.g., 1 roll/100 meters) to test market viability.

Interlining is relatively lightweight but high-volume. To optimize costs, use FOB (Free On Board) terms to maintain control over your freight forwarder and shipping routes. For large orders, Full Container Load (FCL) is more cost-effective than LCL to prevent the rolls from being crushed by heavier cargo. Ensure the HS Code (typically 5603 or 5903) is correctly declared to avoid customs delays and incorrect duty applications.

Always verify the supplier's Business License and Export Qualifications through the Audit Reports available on Made-in-China.com. Utilize Escrow-based payment methods where funds are only released upon confirmation of receipt and quality. Avoid direct wire transfers to private accounts; always use the official corporate bank account listed on the verified platform profile.
