An approved sample does not identify every unit in a bulk shipment. Before release, compare the batch against the agreed model, configuration, connector, label and quantity for each order line. Ask for evidence that can be linked to the delivered units, and keep unresolved substitutions out of the shipment approval.
Freeze the reference before requesting photographs
This checklist is for importers, distributors and vehicle procurement teams receiving several industrial charger configurations. It addresses order fulfilment, not a claim about our factory's inspection process. Agree the evidence and inspection scope with the supplier before production or shipment.
The reference should be the approved order specification and any signed-off changes. Include the exact model, battery charge profile, rated current, input requirement, connector/harness revision, ordered options, artwork revision and quantity per variant. Identify the approved sample or approval record where one exists.
If different people approved the sample, artwork and commercial order, reconcile those records first. Otherwise a shipment photograph may match one document while contradicting another. A clear reference makes a disagreement easier to resolve without debating which email was the final instruction.
Check each order line, not just a representative unit
| Check | Evidence to agree with the supplier | Release question |
|---|---|---|
| Model and configuration | Model identification and configuration record | Does it match the approved order line? |
| Charge profile | Record identifying the approved profile/version | Is the requested battery configuration recorded? |
| Connector and harness | Approved drawing and identifiable batch evidence | Are connector type and harness revision correct? |
| Optional features | Ordered option list and relevant evidence | Are the exact agreed options included? |
| Branding label | Legible label image against approved artwork | Is the correct revision used without hiding required information? |
| Packing and quantity | Packing list and carton-to-variant mapping | Can receiving staff identify every variant and quantity? |
Photographs help confirm visible features. They do not prove an internal charging profile, a pin assignment or full electrical performance. Where a requirement is not visible, agree a suitable configuration record or inspection method rather than asking for more exterior photos.
Keep mixed configurations easy to identify
A shipment may contain 36V/18A golf cart chargers alongside 48V/15A units, or different current ratings for other applications. Those ratings alone do not capture chemistry, BMS requirements or optional interfaces. Give each approved variant a unique order reference.
Ask the supplier to connect that reference to the packing list and carton identification. Receiving staff should be able to separate variants without connecting units to batteries to find out which is which. Agree how any split carton or mixed carton will be identified before loading.
Do not prescribe a numbering system the supplier cannot support. The practical requirement is traceability between the order line, inspected evidence and received items. If serial numbers are available, agree how they will be recorded. If not, agree another suitable batch identification method.
Look closely at substitutions
A different connector that fits mechanically may have different electrical assignments. A different cable length can affect installation. A model from the same wattage family may omit a probe, auxiliary output or enable interface that the approved sample had.
Treat changes as separate approval decisions, not as minor packing details. Ask the supplier to identify the reason, affected quantity and technical difference. Obtain the responsible technical and commercial approvals before accepting the change. Verbal reassurance that it is equivalent is not a replacement for documented review.
The connector compatibility guide explains why visual similarity is insufficient. The sample inspection guide covers the earlier product-validation stage; passing that stage does not waive batch checks.
Labels and compliance records need the same model identity
Compare the label with the approved artwork and exact ordered model. Check that required ratings and identification remain legible. Branding must not obscure information needed for safe selection, installation or traceability.
The supplier reports CE, FCC and RoHS documentation availability. Request applicable documents for the ordered model and intended market, and have the responsible compliance party assess their scope. A logo on a label or a report for another model is not proof that the shipment meets every destination requirement.
For the document questions to ask, see our USA and EU compliance guide. Keep the model references consistent between the purchase order, product label, packing records and relevant technical documents.
Agree inspection scope before interpreting results
Specify whether the agreed checks cover every unit, selected units, or documents only. If sampling is used, agree the method, acceptance criteria and response to nonconformities with the inspection party. Do not describe a photograph of one charger as evidence that the entire batch was functionally tested.
Electrical tests need qualified personnel, approved equipment and a defined procedure. Buyers should request the agreed records rather than improvise hazardous tests. Any claims about test coverage must match the actual inspection scope and evidence supplied.
Record each release item as accepted, open or not applicable, with an evidence reference and reviewer. Explain not-applicable decisions. A blank cell is not an approval. Open items affecting battery suitability, interfaces, ratings or ordered quantity should be resolved before the affected goods are released. If a partial shipment is proposed, explicitly identify the approved order lines and quantities; do not let approval of one variant release unresolved variants.
Make receiving inspection easier
Send the final packing list, configuration references and relevant documents to the receiving team before arrival. Retain shipment photos where agreed, noting which batch or cartons they show. Ask receiving staff to report damage, identification discrepancies and quantity differences before assigning chargers to vehicles.
If there is a mismatch, isolate the affected units and contact the supplier with the order line, batch details and safe external photographs. Do not correct a connector or rewrite a rating label locally to make the delivery match the order.
Put the release requirements in the quotation request
For a bulk industrial charger quotation, provide quantity per variant, battery specifications, interfaces, artwork requirements, destination and requested inspection/document package. Confirm availability and any inspection charges before approval; no unconfirmed service should be treated as included.
MOQ is 30 units. Branding labels are available from 200 units, subject to artwork confirmation; mixed-model eligibility needs confirmation. Production is approximately 15-30 days depending on order quantity and configuration, with shipping time separate. Agree when approvals are needed and how unresolved checks affect shipment timing.
Questions buyers ask
Can shipment photos replace a third-party inspection?
No. They may support visible checks but do not provide the same scope or independence. Choose the inspection approach according to the order risk and agreed requirements.
Do branding labels mean custom packaging is included?
No. Packaging, manuals and other custom work need separate confirmation. Our private-label order checklist explains what to clarify before production.
Define the bulk order checks
Send quantity per variant, approved configuration references, destination and requested shipment evidence. Agree the inspection scope and any charges before order approval.
