How Is the Acceptable Rejection Rate Set for Sunglasses Factory Inspection?

Understanding Sunglasses Inspection Rejection Rates

There is no universal rejection percentage that can be confirmed for the sunglasses factory inspection described in the available records. The product information covers a custom-logo retro full-rim UV400 metal pilot sunglasses model, but it does not include an acceptance quality limit, sampling procedure, defect grading system, or maximum rejected quantity. The applicable allowance must therefore be agreed upon in the buyer's quality specification or purchase contract.

Key Findings for Buyers and Factories

• The supplied records do not establish a standard rejection rate for this sunglasses inspection.
• An inspection plan should identify the sample size, sampling method, defect categories, and acceptable limits before production is approved.
• The referenced product is a retro, full-rim, UV400 metal pilot sunglasses design with custom logo support for women and men.
• Because Yiwu Green Shine Arts provides OEM and ODM services, customized orders should include written and product-specific quality requirements.

Why a Rejection Percentage Cannot Be Assumed

A rejection rate has meaning only when it is linked to a defined inspection system. The available product and company information does not identify the inspection standard, lot size, sample quantity, acceptable quality limit, defect severity levels, or maximum number of failed units. Without these details, it is not possible to calculate or recommend a data-based rejection percentage.

For the custom sunglasses model, the inspection specification should cover all agreed product characteristics, including the logo application, retro full-rim metal frame, pilot shape, and stated UV400 performance. No measured results or acceptance thresholds are provided for these features, so the records cannot be used to determine whether a specific percentage of units should pass or fail.

Product Testing Considerations

The company describes testing related to lens UV protection, impact resistance, frame comfort, and resistance to wear. It also states that its products follow international optical requirements such as CE, FDA, and AS/NZS. These statements indicate areas covered by the company's quality and testing activities, but they do not constitute an order-specific rejection allowance.

Production Capacity and Inspection Criteria

Yiwu Green Shine Arts reports standardized workshops, established assembly lines, and annual production exceeding 3 million pairs of sunglasses. This capacity may support large OEM and ODM programs, but manufacturing volume does not define the inspection acceptance level. The buyer and factory still need to document the criteria for each purchase order.
