Top 20 questions to ask your private label lash supplier

When you start a lash brand, one of the most crucial decisions you’ll make is choosing the right private label lash supplier. This decision impacts not just the quality of your lash products but also your brand reputation, customer satisfaction, and long-term business growth.

As a seasoned eyelash extension manufacturer, Charmlash has supported thousands of lash businesses worldwide. Based on that experience, we’ve created this list of key questions every brand owner should ask before committing to a supplier. Whether you’re sourcing wholesale lash extensions, planning custom lash packaging, or simply trying to start a lash business the smart way, these questions will guide your decision.

Why choosing the right private label lash supplier matters

Choosing the right lash supplier isn’t just about who has the lowest price or fastest shipping. Your supplier influences:

• Retention and client satisfaction: Poor-quality lashes or glue lead to complaints and refund requests.
• Your brand reputation: Inconsistent curls, poor packaging, or allergic reactions can ruin first impressions.
• Long-term business success: A reliable supplier becomes your behind-the-scenes partner, not just a vendor.

20 Key questions to ask your lash supplier

Relate to product quality & variety

Product is the core of your lash brand. The quality and range of your lash extensions directly affect client satisfaction, lash retention, and how well your brand stands out in a competitive market. Choosing a private label lash supplier with consistent, high-quality, and diverse products will give your business the best chance to grow. Here’s what you need to ask:

1. What materials are your lashes made from?
   Lash extension materials vary greatly in quality. Most premium lashes are made from PBT (Polybutylene Terephthalate), a durable and flexible synthetic fiber known for its natural look and softness. Inferior materials can cause stiffness, poor curl retention, or even allergic reactions. Always confirm the material source and grade to ensure safety and consistency across orders.
2. Are your lashes cruelty-free and hypoallergenic?
   Consumers today are more conscious than ever. Offering cruelty-free lash extensions not only aligns with ethical practices but also expands your customer base. Hypoallergenic lashes are essential for sensitive clients to avoid irritation or reactions. Asking this question helps you meet modern beauty standards and keep client trust.

1. Do you offer various types (individual, premade/promade fans, colored lashes, etc.)?
   A versatile product line allows you to cater to different lash artists and end users. Look for a supplier that offers popular types like individual lash, premade/promade lash as well as trending options such as brown lashes, matte color lashes, neon lashes. This gives you the flexibility to meet evolving customer demands and stay ahead of lash trends.
2. Can I see a chart of your curls, thicknesses, and lengths?
   Curl names and shapes can vary slightly between lash manufacturers, so it’s essential to double-check how each supplier defines them. What one supplier calls a “D” curl might be closer to a “CC” from another. Asking for a detailed lash chart helps you avoid inconsistencies and build a reliable product menu. A professional lash supplier should provide a full overview of their range, including popular curls (C, CC, D, DD) and specialty curls (L, M, L+, LD, V), thicknesses (typically from 0.03 to 0.20), and lengths (from 6mm to 20mm or more). This clarity ensures you’re offering precise styling options that meet your clients’ needs.
   
   
3. How is your lash retention and softness compared to other suppliers?
   Client retention isn’t just about lash glue—it’s also about the lash itself. Ask if the supplier offers retention lash extensions, like laser lashes, which have a textured base that improves bonding and retention. Softness also matters for comfort and natural appearance. High-quality lashes should feel soft to the touch without compromising durability.

Relate to product quality & variety

No matter how beautiful the samples look, inconsistent quality in bulk orders can hurt your brand. Reliable quality control ensures your customers always get the same great lashes—every time. A private label lash supplier who prioritizes consistency will help you avoid product returns and unhappy clients.

1. Do you have a quality control process?
   Ask for details. A trustworthy lash supplier should have a strict inspection process to check curl accuracy, lash placement, packaging condition, and cleanliness before shipping.
2. Can I order samples before committing to a bulk purchase?
   Sampling lets you test the product quality firsthand—from curl consistency and lash softness to tray design. It also helps you assess retention performance on real clients.
3. How do you ensure consistency between batches?
   Lash buyers often face issues where bulk orders differ from samples. Ask how the supplier monitors batch production, especially if you’re planning to scale. You’ll want consistent retention, curl, and softness across every box.

Private Label & Branding Options

Your packaging is your first impression. Customizing lash trays, labels, and boxes with your brand identity can elevate your perceived value and boost client trust. The right private label lash supplier should offer flexible branding options that support your vision.

1. Do you offer private labeling services?
   Not all vendors support private labeling. Clarify if they can print your logo, use custom box designs, or even create branded inserts.
2. Can I customize lash trays or packaging with my brand?
   Look into available design templates, colors, and material options. High-quality packaging strengthens your brand presence, especially if you sell online or through retailers.
3. What is your MOQ (minimum order quantity) for private label orders?
   Some manufacturers have high MOQs that may not suit small or new businesses. Ask about order flexibility—low MOQ options make it easier to test the market without overstocking.

Relate to Shipping & Logistics

Late shipments or unclear logistics can delay your launch and damage customer trust. Understanding how your lash supplier handles orders and problems ensures smoother operations.

12. How long is your production and shipping time?
    Ask for timelines from order confirmation to delivery. Are rush orders available? Can they meet your restock needs quickly?
13. Which countries do you ship to?
    Global reach is essential, especially if you’re scaling internationally. Confirm they can deliver to your location and ask about their shipping partners.
14. Do you offer tracking and handle lost/damaged orders?
    Reliable suppliers should provide tracking numbers and take responsibility for shipping issues. Ask how they handle lost packages or customs delays.

Relate to Customer Service & Support

Good customer service saves you time and stress. Having a direct contact person or account manager can make your ordering experience smoother, especially when issues arise or you need reorders fast.

15. Do you have a dedicated account manager or customer service contact?
    A responsive supplier who understands your brand and order history can provide personalized support, faster resolutions, and better results.
16. Do you provide lash product training or branding support?
    Some suppliers go beyond product delivery—they help you succeed with how-to guides, training videos, or marketing assets. This is especially helpful for new lash brand owners.
17. Can I reorder easily, and how do you handle out-of-stock items?
    Your business depends on restocking. Ask if they notify clients about stock availability, offer pre-orders, or suggest alternatives when items are out.

Relate to Pricing & Policies

Clear pricing, fair policies, and bulk discounts can help you manage your margins better—especially as your business grows. Be transparent about costs and conditions from day one.

18. Do you offer tiered pricing for bulk orders?
    Tiered pricing lets you save more as you order more. This is a good sign that the supplier supports growth-focused businesses.
19. What is your return or refund policy?
    You need clarity in case of damaged goods or inconsistencies. Ask how they handle quality issues, incorrect orders, or late deliveries.
20. Do you offer discounts or deals for long-term partners?
    Many manufacturers offer loyalty programs, annual deals, or exclusive discounts for repeat customers. It’s worth asking early on.

Red flags to watch out for

While asking the right questions helps you find a strong partner, these warning signs can help you avoid risky lash suppliers:

• Slow or vague responses: If they take too long to reply or avoid direct answers, it may signal poor communication later on.
  
• Inconsistent samples vs. bulk orders: If your test order and real order are totally different, it’s a major red flag.
  
• No reviews or online presence: A reliable private label lash supplier should have visible proof of work—whether on Instagram, a website, or trusted marketplaces.
  
• High pressure to place bulk orders: Legit suppliers let you test samples and ask questions first. Avoid those who push for payment without trust.
