Sequin

When sourcing sequins, the primary material is usually PVC (Polyvinyl Chloride) or PET (Polyethylene Terephthalate). For high-end fashion, PET is preferred because it is heat-resistant, more environmentally friendly, and less prone to warping during ironing or dry cleaning. You should also verify the thickness (typically 0.15mm to 0.25mm) to ensure a balance between flexibility and durability.

To ensure quality, request products that have undergone electroplating or vacuum plating for metallic finishes, as these offer better abrasion resistance. Ask for ISO 105-E04 (colorfastness to perspiration) and ISO 105-X12 (colorfastness to rubbing) test reports. For outdoor or stage use, ensure the sequins have an UV-resistant coating to prevent fading under intense lighting or sunlight.

For the EU, sequins must comply with REACH regulations, specifically regarding lead, cadmium, and phthalate content. For the US market, especially if used in children's apparel, they must meet CPSIA standards. Always request a Certificate of Compliance (CoC) or a Third-Party Lab Test Report (such as from SGS or Intertek) to avoid customs seizures.

Sequins come as loose sequins for hand-embroidery, sequin film/rolls for punching machines, or sequin fabric. If sourcing fabric, check the base mesh quality and the stitching density. For automated garment production, ensure the sequins are uniform in shape and hole placement to prevent machine jamming.

Color inconsistency between batches is a common risk. You should request a 'Golden Sample' before mass production and insist that the supplier uses the same dye lot for your entire order. For repeat orders, provide the supplier with a Pantone TCX/TPG reference or a physical swatch to maintain brand consistency.

Focus on Tiered Pricing; sequin production is highly scalable, so you can often negotiate a 15-20% discount when moving from 50kg to 500kg. Additionally, negotiate for customized packaging (e.g., moisture-proof bags) to be included in the unit price to protect the goods during long-term sea freight.

Sequin fabrics are heavy and prone to snagging. Ensure the supplier uses roll-packing with a protective plastic film rather than folding, which can crease the sequins. For international shipping, specify double-layered corrugated boxes and palletization to prevent crushing during transit.

Always use Secured Payment services provided by reputable platforms like Made-in-China.com to ensure your funds are only released after you confirm receipt of goods. For large orders, consider hiring a third-party inspection service to conduct a Pre-Shipment Inspection (PSI) to verify quantity and quality before the final payment is made.
