Eyelashes extension

B2B buyers should prioritize PBT (Polybutylene Terephthalate) fiber, commonly referred to as Korean Silk or Faux Mink, due to its superior shape retention and heat resistance. Ensure the supplier provides a variety of curls (J, B, C, D, CC, L, U) and thicknesses (ranging from 0.03mm for mega-volume to 0.20mm for classic sets). High-quality lashes must have tapered tips and a non-stick strip that allows for easy fan creation without residue.

Safety is paramount as these products are used near the eyes. Request MSDS (Material Safety Data Sheets) for adhesives and lash fibers. Ensure products comply with REACH (EU) or FDA (US) cosmetic regulations. Look for suppliers with ISO 9001 certification for manufacturing consistency and SGS or Intertek lab reports verifying that the fibers are free from heavy metals and formaldehyde.

Premium lashes are characterized by color consistency (deep matte black without a blue tint) and curl stability (maintaining shape for at least 6-12 months). For volume lashing, look for 'Easy Fan' or 'Auto-fan' technology, which involves a specific glue treatment at the base of the strip. Additionally, foil-backed strips are preferred over paper ones as they can be peeled off lash tiles repeatedly without leaving messy paper residue.

Most professional suppliers on Made-in-China.com offer extensive private label services. This includes customized lash cards, branded outer boxes (paper, plastic, or magnetic), and private label adhesives. When requesting OEM, specify the GSM of the cardstock and the printing technique (e.g., gold foil, UV coating) to ensure the packaging reflects a high-end brand image.

Always order a sample kit before committing to a bulk purchase to test the curl longevity and fiber softness. Implement a Pre-Shipment Inspection (PSI) through a third-party agency or request a video inspection where the supplier demonstrates the 'pull test' and curl comparison against your approved gold sample.

Focus on Tiered Pricing; for example, negotiate a lower unit price for orders exceeding 500 or 1,000 trays. Instead of just pushing for the lowest price, negotiate for value-adds such as free logo design, lower MOQs for new curl types, or extended payment terms (Net 30) for repeat orders. Mention that you are sourcing via Made-in-China.com to leverage the platform's supplier accountability.

Since eyelash extensions are lightweight and high-value, Air Express (DHL, FedEx, or UPS) is the most efficient method, typically delivering within 3-7 business days. For larger bulk orders (e.g., 5,000+ trays), consider Air Freight to a local airport to balance cost and speed. Ensure the supplier uses moisture-proof packaging and sturdy outer cartons to prevent the lash boxes from cracking during transit.

Utilize the Secured Trading services provided by Made-in-China.com to ensure your payment is held in escrow until delivery is confirmed. Avoid using untraceable payment methods for initial transactions. Ensure the Proforma Invoice (PI) clearly states the refund policy for defective items (e.g., a 1%–3% defect allowance or full replacement for curl loss).
