Laboratory testing fails in practice for boring reasons: the wrong samples sent, the wrong standard requested, the report nobody knows how to read. CGF’s testing service is built around removing those failures. We do not run a laboratory ourselves — the analysis is performed by accredited third-party laboratories — but we own everything on either side of it: deciding what to test, drawing the samples properly, and making the results legible.

Step by step: from regulation to report

1. Define the target. You name the product and the market it ships to; the coordinator then maps the regulations that actually apply — chemical restrictions, safety standards, labelling rules — instead of selling a generic package.
2. Fix the schedule and the fee. Each test is listed with its method, turnaround and cost as a fixed-fee quote, agreed before anything moves.
3. Draw the samples correctly. Where results must represent a shipment, a CGF inspector pulls the required units at random from bulk production, seals and documents them. Samples that “happen” to be the factory’s best pieces make every downstream number meaningless.
4. Submit and chase. Samples go to the accredited partner laboratory with a documented chain of custody; we track progress against the quoted turnaround so the calendar does not drift.
5. Deliver and explain. The laboratory’s PDF report reaches you together with a plain-English summary: what passed, what failed, and what to do next if something failed.

How to read the test report you get back

• Sample identity. The report’s sample photos and identifiers must match the units drawn from your lot — this is the link between the results and your goods.
• Method references. Each line should cite the standard and version used, so your own customers or auditors can verify it independently.
• Result against limit. For every substance or property, the measured value sits next to the legal or contractual limit — the distance between those numbers is your safety margin.
• Conclusion per item. Pass or fail is stated per test, not smeared across an overall impression.
• Laboratory identity. The issuing laboratory’s name and credentials appear on the report; the testing itself stays with accredited third-party labs, with our role documented as sampling, witnessing and coordination.

Typical schedules by category

• Textiles and apparel: fibre composition, colour fastness to washing, rubbing and light, restricted azo dyes.
• Electronics: restricted substances (RoHS-style screens), safety-marking checks, battery transport requirements.
• Children’s products: mechanical and physical hazards, chemical limits under the destination market’s toy standard.
• Food contact: migration testing on plastics, silicone, ceramics and metals for the relevant market.

Samples, costs and retests

Test quantities vary widely — one unit may serve a chemical screen, while a destructive mechanical test can consume dozens — so the coordinator confirms per-test quantities when quoting, and the inspector can draw the full set from production in a single visit. Laboratory fees are passed through transparently with our coordination shown separately in the fixed-fee quote; nothing is marked up silently. Keep spare units aside wherever possible, because a failed item needs fresh samples for the retest, and units that have already been through a lab cannot represent the lot twice. Turnaround depends on the schedule: simple chemical screens run in days, full compliance packages take longer and are quoted with real dates rather than optimism.

Testing is one pillar of a wider station: CGF also inspects, stores and reworks, with 95 inspectors across China and a 2,000+ m² Dongguan base behind the laboratory coordination. The about page sets out who we are and what the base does.

Pairing tests with inspections

A passing test on one sample proves the material; an inspection proves the shipment. The strongest programmes run both: compliance testing before or during production, then a final random inspection so the container matches the certificate. See the gate map on the product inspection page and the final gate in detail under pre-shipment inspection.
