Eyelash extension

When sourcing eyelash extensions, the primary material is usually PBT (Polybutylene Terephthalate), often marketed as 'Silk' or 'Mink'. You must verify the fiber consistency, ensuring the tips are tapered naturally and the color is a deep, matte black without a blue tint. Key technical specs include curl retention (tested under high temperatures), diameter precision (ranging from 0.03mm to 0.25mm), and strip stickiness, which should allow for easy pickup without leaving residue on the lash.

Since these products are used near the eyes, compliance is non-negotiable. Ensure the manufacturer adheres to ISO 22716 (GMP for Cosmetics). For adhesives, request MSDS (Material Safety Data Sheets) to check for formaldehyde and latex content. Products destined for the EU must comply with REACH regulations, while US-bound goods should meet FDA labeling requirements for cosmetic accessories.

To optimize costs, analyze the price per tray vs. the number of lines per tray (standard is 12, but 16 or 20 lines offer better value). Negotiate bulk discounts for orders exceeding 500 trays, where you can typically see a 15-25% reduction in unit price. Additionally, consider Private Label (OEM) costs; while there is an initial plate-making fee, it builds brand equity and long-term margins.

Lashes are categorized by application: Classic (1:1), Volume (fans), and Mega Volume. Functional requirements include easy-fan technology for beginners and heat-resistance for clients in humid climates. For professional salon use, the foil-back strips are preferred over paper backs as they can be peeled and repositioned on lash tiles without tearing.

The most frequent risk is quality inconsistency between batches, where the curl (e.g., D-curl) may vary between orders. To mitigate this, use Made-in-China.com's inspection services or request a pre-shipment sample. Another risk is shipping damage to the fragile acrylic lash cases; ensure the supplier uses double-walled cartons and bubble wrap reinforcement.

Always insist on Trade Terms that include a quality guarantee period (usually 6 months for lash curls). Use Secured Payment methods provided by platforms like Made-in-China.com to ensure funds are only released upon confirmation of receipt. Negotiate a 30% deposit and 70% balance payment after passing a third-party quality inspection.

Eyelash adhesives are often classified as dangerous goods (Class 3 Flammable Liquids) due to cyanoacrylate content. They require specialized chemical packaging and must be shipped via sensitive cargo channels. Ensure your supplier provides a Certificate for Safe Transport of Chemical Goods to avoid customs seizures or shipping delays.
