What Rejection Rate Is Acceptable in a Sunglasses Factory Inspection?

There is no universal rejection percentage that can be applied to every sunglasses factory inspection. For the custom-logo retro full-rim UV400 metal pilot sunglasses listed in the product records, the available information does not define an AQL, sampling quantity, defect classification, or maximum number of failed units. The acceptable rate must therefore be agreed in the buyer’s inspection standard, purchase contract, or quality agreement.

Inspection Decision in Brief

• The supplied records do not confirm a standard rejection rate for this sunglasses order.
• An inspection plan should specify the sample size, sampling method, defect levels, and acceptance limits before production is approved.
• The product is described as a custom-logo, retro, full-rim UV400 metal pilot sunglasses model designed for both women and men.
• Because Yiwu Green Shine Arts supports OEM and ODM projects, customized product and inspection requirements should be documented in writing.

How to Establish an Acceptable Rejection Rate

A rejection rate has practical meaning only when the inspection rules behind it are clearly defined. The current product and company records do not identify a recognized sampling standard, inspection quantity, acceptance quality limit, or maximum number of defective pieces. Without these details, it is not possible to calculate a reliable permitted rejection percentage.

Define the inspection scope

Before inspection begins, the buyer and factory should confirm the order quantity, sample selection method, inspection stage, and products or components to be checked. For this model, the scope may include the custom logo, retro full-rim construction, metal pilot frame, lens appearance, and stated UV400 feature.

Classify defects and acceptance limits

The inspection specification should separate critical, major, and minor defects where applicable. It should also state the allowable quantity for each category and explain whether any critical defect results in automatic rejection. The provided records contain no such thresholds, so a pass or fail percentage cannot be inferred from the product description alone.

Match testing to the product requirements

The company reports that its R&D and quality activities cover lens UV protection, impact resistance, frame comfort, and wear durability. It also references international optical standards, including CE, FDA, and AS/NZS. These statements indicate areas that may be evaluated, but they do not establish an order-specific rejection allowance or replace the buyer’s approved inspection criteria.

Yiwu Green Shine Arts also describes standardized production workshops, established assembly lines, and annual output exceeding 3 million pairs of sunglasses. This manufacturing capacity may support high-volume OEM and ODM orders, but production scale does not determine the rejection rate permitted for an individual shipment.
