Project quality planning
Eyewear quality control for an OEM or ODM order begins with the buyer-approved physical sample and written specification. Project checkpoints may cover materials, dimensions, assembly, lenses, logos, appearance and packaging. The inspection method, sampling level, evidence and destination-market testing are agreed for the final product rather than assumed from a general factory claim.
Discuss your quality requirements ↗No certification or test report is represented on this page unless a document is specifically identified and made available for the relevant product and order. Destination-market tests and documentation must be specified before order confirmation.
Buyer-defined evidence
The controlling reference
A custom frame cannot be inspected consistently without agreed requirements for materials, dimensions, colors, lenses, logos, packaging and acceptable variation. The approved physical sample together with the written production specification should provide the main reference. Any approved change should also be documented.
XH Glasses coordinates project information between the international customer, Wuxi Xinjintai International Trade Co., Ltd. and the production team at Ronghao (Shenzhen) Glasses Co., Ltd. The applicable checkpoints, sampling level and acceptance method can be agreed before production.
Depending on the order, the reference package may include the approved sample, drawing or measurement table, material direction, frame and temple colors, lens requirements, logo artwork and placement, surface appearance, components, packaging and requested inspection or testing instructions.
Relevant inputs may be compared with the agreed project information. Acetate review can include visible color, pattern, transparency and frame-to-temple relationship. Metal review can include construction direction, components, surface color, temple tips and nose-pad route. Lens and logo components are reviewed against the ordered direction.
Depending on the project, checks may cover visible workmanship, frame-front shape, temple alignment, bridge and rim appearance, hinge movement, component position, surface appearance, color consistency, lens fitting, and logo position or readability. The inspection frequency depends on construction, quantity, identified risks and the agreed plan.
An assembled frame may be reviewed for temple opening and closing, general hinge function, temple position, lens seating, applicable nose-pad position, decorative-part security, general alignment and obvious sharp edges or surface defects. These are review directions, not a universal published test standard.
Appearance review may include cleanliness, visible marks, frame and temple finish, color relationships, lens appearance, print readability, engraving effect and metal-decoration position. Printed, laser and metal applications behave differently on each material, so the approved physical sample establishes the intended result.
Where packaging is included, the plan may confirm the correct model and color, demo lenses, case, pouch, cloth, cards, labels, quantities, carton marking and visible packing condition. A pre-shipment inspection arrangement can be included in the agreed order plan. Packaging review does not establish transport-test performance unless that testing is specified.
Customer-defined inspection
A buyer may provide its own checklist, measurements, sampling plan, acceptance level or third-party inspection company. These requirements should be submitted before order confirmation so scope, timing, responsibility and cost can be included in planning.
Depending on the agreement, the plan may include comparison with an approved sample, defined measurement points, a specified inspection sample size, pre-shipment review, third-party access, required product testing, or photo and summary records. We do not state that a particular AQL level, retained sample or third-party inspection is automatically included.
Where third-party testing is requested, the test scope, laboratory, samples, destination-market standard, timing and cost are agreed separately. Testing statements apply only to the identified product and order.
When a difference is found
The response depends on the nature, extent and timing of the difference.
Describe the observed difference without hiding it in general language.
Check the approved sample, written specification and documented changes.
Identify or separate affected goods where practical.
Assess correction, rework, replacement or reproduction options.
Agree the action before shipment where customer approval is required.
Timing and scope
Typical MOQ starts from 300 pairs per style in total, with colors combined, subject to materials and components. Sampling typically takes 7–10 working days after requirements are confirmed. Bulk production typically takes around 25 working days after sample approval and production details are confirmed.
Under standard project conditions, available capacity can reach approximately 1,000 pairs per day. Additional checkpoints, third-party inspection, specialist tests, documentation, rework or approved changes can affect cost and timing. Lead times are production estimates, not shipment or arrival guarantees.
Final inspection scope, evidence and shipment-release arrangements should be stated in the quotation, order information or other agreed project document.
Frequently asked questions
No fixed AQL level is represented as automatically included. If the buyer requires a particular sampling plan or acceptance level, it should be supplied and agreed before order confirmation.
No. Test reports are not universal across products. Required standards, test scope, laboratory arrangements, samples, cost and timing must be confirmed for the relevant product and order.
The approved physical sample together with the written production specification should form the primary reference. Any approved changes should also be recorded.
A third-party pre-shipment inspection can be discussed. Access, timing, scope, sampling method, responsibility and cost must be agreed in advance.
