HomeQuality and compliance

What we check, and what we do not have.

Most supplier pages list certificates and stop. A certificate says the process is written down. It does not say what came off the line this week. This page covers both, including the parts we cannot answer.

Thirteen checks, in order

The list follows the product. Not every model gets every check, and the exact set is agreed per order and printed on the inspection sheet. What does not change is where the checks happen: on the line and in the lab beside it, before the carton is taped.

Incoming

01Material certificateResin certificate for the batch, filed against the order number.
02Color matchCompared to the approved color chip under D65 light, not to a screen.
03Material screeningXRF scan for restricted elements, on the resin and on a part per batch.

In process

04AppearanceBlack spots, drag marks, sink, flash at the parting line.
05Key dimensionsWall thickness and camera opening measured on the 2.5D machine.
06ThicknessThree points per part with a micrometer, against the drawing tolerance.
07Magnet pullPull force in newtons on every MagSafe model, sampled per cavity.
08Fit and feelButtons, port cutouts and clip force checked by hand on the first shot.

Finishing

09Print adhesionCross hatch and tape pull on a printed part from each print run.
10AbrasionRCA paper tape test on coated and painted surfaces.

Before the carton

11Drop testWhole unit drop on the protection models, at the height the model is rated for.
12AgingThermal shock and constant temperature humidity on the finish.
13Final samplingAQL sample from the packing table, opened and inspected, not pulled from the line.

The equipment

Six instruments do most of the work. All of them are in the Dongguan plant, and all of them are ours, not a lab we send samples to.

2.5D measuring machineWall thickness, camera opening, magnet pocket depth. A screen with a probe, not a caliper.
X-ray fluorescence (XRF)Material screening for restricted elements. Used for incoming resin and for a part per batch.
RCA abrasion testerCoating and print wear, measured in cycles to substrate.
Thermal shock chamberHot and cold cycling on the finished part, for finish and for dimensional stability.
Constant temperature humidity chamberLong soak for yellowing and for adhesive failure on laminated parts.
Tensile tester, 0 to 500 NMagnet pull and clip force, read off the same gauge the drawing quotes.

Certificates

Four management system certificates, all current, issued by Zhongbiaoyan Guolian (Beijing) Certification. The scope on each one is plastic mold and injection molded parts, phone cases.

Where a certificate stops

A system certificate covers how the plant is run. It is not a test report for a phone case. Buyers mix the two up, and then a purchase order is held at customs over a document that was never the right one.

What we do hold: material level RoHS, halogen free and REACH statements from the compound suppliers, dated 2023. They cover the resin as delivered, and they name the grade. Ask for the file and we send it with the model it applies to.

What that does not cover: the finished case. A molded part has pigment, plating, an adhesive and a magnet that the resin report says nothing about. A finished part report is run per model and per color, and it is paid per test.

What we do not have

CE and FCC. We do not hold our own reports. Phone cases do not need them. The models with electronics, such as the screen case, do, and the test is run per order with the cost inside the quote. Do not assume a file exists.

GRS. Our GRS certificate lapsed in June 2026. If your program needs a recycled content claim, tell us before you specify it, and we can tell you what we can and cannot support. A certificate alone would not cover a shipment either, because recycled content needs a transaction certificate per batch.

SMETA. The four pillar audit was completed on 31 July 2025 and the cycle is twelve months. The 2025 report raised three findings, on electrical safety, social insurance and overtime. Ask for the report and where those three stand now, not the report on its own.

EU GPSR. Regulation (EU) 2023/988 applies since 13 December 2024 and requires a responsible person inside the EU. We do not appoint one on our own. For an EU program the importer usually carries that role, and we supply the technical file it needs.

If you need a document for a model

Send the model, the market and the standard. We answer with one of three things: the file exists and here it is, the file does not exist and here is what it costs to run, or the file does not exist and we cannot get it in your timeline. The third answer is the one that saves a shipment.
