Premade Fan Sample Defects That Justify Batch Rejection

A premade fan shipment should be approved only when the production sample matches the specifications confirmed for the order. Material, thickness, length, curl, fan design, and tray presentation must align with the approved reference. When any of these elements differ, or when documented quality checks reveal a nonconformity, the batch should be rejected or placed on hold pending resolution.

Start With the Approved Order Specification

Sample evaluation should be based on the written purchase specification and approved reference sample, not on general visual preference. This premade lash range is available in Korean PBT fiber, silk, and cashmere. Thickness options include 0.03 mm, 0.05 mm, and 0.07 mm, while lengths range from 6 mm to 18 mm, including mixed-length selections.

Available curl choices are J, B, C, CC, D, DD, L, L+, M, LC, and LU. Since the range includes multiple combinations, a sample is not acceptable merely because it falls within the supplier's general offering. It must match the exact material, curl, thickness, length, and premade fan option selected for the order.

Defects and Mismatches That Require Action

Specification Differences

Reject the sample or hold the full batch when the lash material differs from the approved selection, such as receiving silk when Korean PBT fiber was ordered. The same principle applies to an incorrect thickness, an unapproved length or mixed-length sequence, or a curl that does not correspond with the purchase order.

Fan configuration is equally important. The product is presented as a 12-row premade lash range with narrow premade volume fan options. Confirm the selected fan dimension, shape, and tray arrangement in writing before production begins. A delivered sample that differs from the approved fan style or tray presentation should not be used as a production acceptance reference.

Quality-Control Failures

The stated quality process includes incoming inspection, functional testing, finished-product inspection, and pre-shipment inspection. Ask for the sample and production lot to be checked through these stages. A failed inspection, an identified nonconformity, or the absence of supporting inspection records is a valid reason to reject the shipment or suspend acceptance until the issue is clarified.

No universal tolerance limits for appearance, fan symmetry, bonding behavior, dimensional variation, or tray-count variation are provided in the available product information. Buyers should therefore avoid creating unsupported acceptance limits after production. Instead, document any required tolerances, inspection method, and approval criteria before the order is released.

Who Should Use This Review Process?

This sample-control process is useful for professional lash salons, eyelash extension studios, training academies, and beauty schools. These users depend on stable lash specifications for repeatable application results and teaching consistency. A clear approved sample also helps wholesale buyers maintain consistent quality across repeat purchases.

Supplier credentials should be considered separately from sample approval. Listed credentials include FDA certification for eyelash extension products and an FDA Cosmetic Product Listing for UV eyelash extension glue, each with its own stated product scope. Likewise, a Brazil wholesale cooperation case involving 10,000 trays of eyelash extension fans and accessories reported varied lash styles and consistent quality, but it does not replace inspection of a new customer's own approved sample and production order.

Frequently Asked Questions

Is an incorrect curl sufficient reason to reject a sample?

Yes. Curl is an order-specific requirement. Because this premade fan range offers numerous curl options, a sample with a different curl from the confirmed specification should be rejected or corrected before production approval.

Can a batch be rejected for an incorrect lash length?

Yes. Although the product line covers 6-18 mm lengths and mixed selections, acceptance must be based on the precise length or mix stated in the order. Being within the general catalog range does not make an incorrect length acceptable.

What documents and details should accompany a sample?

Request written confirmation of material, thickness, length, curl, fan configuration, tray presentation, and quality-control status. Inspection information should cover incoming inspection, functional testing, finished-product inspection, and pre-shipment inspection where applicable.

Conclusion

Use the approved premade fan sample and written specification as the basis for batch acceptance. Reject or hold products that differ in material, thickness, length, curl, fan option, or tray presentation, and do not approve a lot that lacks satisfactory inspection evidence.
