FROM REQUEST TO FINAL REFERENCE
A sample process
both teams can follow.
Request
Tell us the model, target devices, market, quantity and customization scope.
Agree
Confirm sample purpose, version, fees, availability, delivery and review criteria.
Evaluate
Check the delivered sample against the agreed list and record observations.
Resolve
Send consolidated feedback. Agree changes and whether another sample is needed.
Confirm
Approve the final reference and written requirements before the bulk order proceeds.
BEFORE BULK PRODUCTION
Confirm the version.
Keep the decisions.
A sample is most useful when it is connected to written requirements. Confirm the details that will guide the order and resolve open points before production approval.
A sample review does not establish performance for every unit or replace applicable compliance verification. The inspection plan and acceptance criteria are agreed separately.

SAMPLE CONFIRMATION FAQ
Before you confirm.
Can we evaluate a sample before placing a bulk order?+
Yes. Contact ZONNGOO with your preferred model, target devices and intended order. Sample availability, configuration, fees and delivery arrangements are confirmed individually.
Is an evaluation sample the same as a customized sample?+
Not necessarily. An existing-model sample may help assess the product format and charging behavior, while a customized sample may include agreed branding or packaging. Confirm exactly what each sample represents before ordering it.
Are samples free, and can the fee be refunded?+
Sample charges, customization or setup costs, shipping and any credit against a later order are confirmed in the quotation. No free-sample or refund policy is assumed for every project.
How long does sample preparation and delivery take?+
Timing depends on stock, customization, components and the destination. Ask for a confirmed preparation estimate and shipping arrangement for your particular sample request.
What should we check when the sample arrives?+
Use the agreed review checklist: appearance, dimensions, artwork, relevant functions, device compatibility, accessories and packaging. Record the sample identifier and test conditions so feedback can be reviewed accurately.
What if we need changes after reviewing the sample?+
Send one consolidated list with photos, observations and the required changes. We will discuss feasibility, any effect on cost or timing, and whether a revised sample or updated artwork proof is required.
Does sample approval replace certification or shipment inspection?+
No. Sample approval records agreement on the reviewed version and criteria. Applicable compliance testing, transport documents and production or shipment inspection remain separate requirements for the exact configuration and market.
How is the approved version recorded?+
Agree a sample reference or version identifier, the final specification, artwork revision, packaging details and any exceptions in writing. Confirm how the physical reference and supporting records will be retained for the project.
