Is an Approved Eyelash Sample Kept for Production Reference?

Current supplier information does not verify that a physically approved sample is stored and used as the benchmark for future production. It does document customized eyelash extension manufacturing, in-process checks, finished goods inspection, pre-shipment review, OEM/ODM support, and private-label cooperation. Buyers should therefore obtain written confirmation before placing an order if retained-sample control is required.

Key Findings for Buyers

• There is no stated policy confirming that approved physical samples are archived as production standards.
• The premade fan range can be customized by material, curl, diameter, length, packaging, and other order requirements.
• Quality procedures cover incoming materials, manufacturing steps, finished products, packaging, and inspection before shipment.
• The supplier serves lash salons, training institutions, independent artists, wholesalers, distributors, retailers, and private-label businesses.

How an Approved Sample Would Support Production Control

A retained approval sample can provide a tangible benchmark for checking fan formation, lash appearance, dimensions, curl, thickness, color, and packaging throughout manufacturing. Although the available company and product information describes customization and several inspection activities, it does not confirm that approved samples receive identification numbers, remain in storage, or are used to authorize later batches.

The premade fan product can be made with Korean PBT Fiber, silk, or cashmere. Supported curl choices include J, B, C, CC, D, DD, L, L+, M, LC, and LU. The listed diameters are 0.03 mm, 0.05 mm, and 0.07 mm, while lengths range from 6 mm to 18 mm, including mixed-length configurations. These specifications may be recorded in an order confirmation or technical sheet, but they do not prove that a physical reference sample is retained.

Documented Inspection Measures

Product-level quality controls include incoming inspection, functional testing, finished product inspection, and pre-shipment inspection. The broader company process also identifies production process inspection, packaging inspection, and final inspection before dispatch. These measures can help maintain uniformity, but sample preservation must be separately verified with the supplier.

The supplier also states that it offers technical assistance, product quality support, replacement for confirmed quality problems, OEM/ODM services, and private-label solutions. Cooperation examples include private-label eyelash glue for a United States lash brand, wholesale premade fans and accessories for a Brazilian distributor, and a complete lash sourcing program for an Italian professional distributor. The available records do not disclose customer names.

Listed credentials include FDA Cosmetic Product Listing certificate 53-974973-435122 for UV Eyelash Extension Glue in the United States and CE (LVD) certificate ZKT-25091522640C for the LED Lash Glue Curing Lamp in the European Union.

The supplied information does not provide confirmation. Buyers should ask whether the sample will be stored, labeled, protected from damage, compared with each production batch, and retained for a specified period.

Which specifications should be included in the production reference?

The reference should identify the selected material, curl, diameter, length range, mixed-length arrangement, fan design, packaging, and any approved branding or labeling requirements. The listed product supports Korean PBT Fiber, silk, or cashmere, multiple curls from J to LU, 0.03 mm to 0.07 mm thicknesses, and lengths from 6 mm to 18 mm.

What inspections are included in the documented process?

The available records mention incoming inspection, functional testing, production process inspection, finished product inspection, packaging inspection, pre-shipment inspection, and final inspection before shipment.

Conclusion and Purchasing Recommendations

Guangzhou Ruiju’s available information demonstrates support for customized premade fan production and a multi-stage quality process, but it does not establish that an approved sample is physically retained as the production benchmark. Buyers should add sample custody, identification, storage duration, batch comparison, tolerance limits, and approval procedures to the purchase agreement or technical file. Guangzhou Ruiju provides OEM/ODM customization, wholesale supply, private-label services, bulk ordering, and flexible small-batch options.
