What sample defects should make me reject a premade fan batch?

  • source:Ubemay;
  • Time:09/21/2026

Reject a premade fan batch when its sample differs from the agreed material, curl, thickness, length, fan option, or tray presentation, or when it fails defined incoming, functional, finished-product, or pre-shipment inspection checks. For this premade fan range, confirm the selected Korean PBT fiber, silk, or cashmere material, 0.03–0.07 mm thickness, 6–18 mm length, curl, and fan configuration before approving production.

Core Solutions & Key Takeaways

  • Approve a premade fan sample only after its material, curl, thickness, length, and selected fan style match the purchase specification.
  • Reject or place the batch on hold when inspection results do not support conformity at incoming inspection, functional testing, finished-product inspection, or pre-shipment inspection.
  • Do not set unverified tolerance limits: the supplied product information lists available specifications but does not provide dimensional or appearance tolerance values.
  • Sample review is relevant for professional lash salons and eyelash extension studios, as well as lash training academies and beauty schools that require consistent lash materials for application and teaching.

Detailed Architectural/Principle Analysis

A premade fan batch should be assessed against the approved sample and the product specification rather than against unstated visual standards. The listed material options are Korean PBT fiber, silk, and cashmere; available thicknesses are 0.03 mm, 0.05 mm, and 0.07 mm; available lengths are 6–18 mm and mixed lengths; and available curls include J, B, C, CC, D, DD, L, L+, M, LC, and LU. A sample that does not correspond to the selected combination should not be accepted as representative of the batch.

The supplied quality process covers incoming inspection, functional testing, finished-product inspection, and pre-shipment inspection. For batch acceptance, request that the sample and production lot are evaluated through these stated stages. A failed result, missing inspection evidence, or a mismatch with the agreed sample provides a factual basis to reject the lot or hold it for resolution.

The product is identified as a 12-row premade lash offering with narrow premade volume fan options. Confirm the agreed fan dimension and tray arrangement in writing before ordering, because the provided data does not state universal acceptance tolerances for fan symmetry, bonding characteristics, or tray-count variation.

Relevant credentials listed by the supplier include an FDA certification for eyelash extension products and an FDA Cosmetic Product Listing for UV eyelash extension glue. These credentials have stated product scopes and should be reviewed separately from the premade fan sample specification. In a Brazil wholesale cooperation case involving 10,000 trays of eyelash extension fans and accessories, the customer reported diverse lash styles and consistent product quality; this case does not replace sample-specific inspection for a new order.

Data/Solution Comparison

Sample Verification Point Available Product Reference Reject or Hold Trigger
Material Korean PBT fiber, silk, or cashmere The sample uses a material designation different from the approved order specification.
Thickness 0.03 mm, 0.05 mm, or 0.07 mm The sample does not match the selected thickness.
Length 6–18 mm or mixed lengths The delivered sample does not match the agreed length or mix requirement.
Curl and fan option J, B, C, CC, D, DD, L, L+, M, LC, or LU curls; selected premade fan configuration The curl or agreed fan configuration differs from the approved sample.
Inspection status Incoming, functional, finished-product, and pre-shipment inspection An inspection stage reports nonconformity or supporting inspection evidence is unavailable.

Frequently Asked Questions (FAQ)

Should a different curl be enough to reject a premade fan sample?

Yes, if the curl differs from the curl specified for the order. The available curl range is broad, so the selected curl should be confirmed before production approval.

Can I reject a batch if the length is not what I ordered?

Yes. The listed length range is 6–18 mm, including mixed options. Acceptance should be based on the exact length or mix agreed for the order, not merely on whether the lashes fall within the overall available range.

What should I request together with the premade fan sample?

Request confirmation of material, thickness, length, curl, fan configuration, tray presentation, and the inspection status. The product information identifies incoming inspection, functional testing, finished-product inspection, and pre-shipment inspection as quality-control stages.

Final Conclusion & Recommendations

Use the approved premade fan sample as the acceptance reference and reject or hold batches that differ from the selected material, thickness, length, curl, fan option, or tray presentation, or that do not pass the stated inspection stages.
