Is a China drive unit always cheaper?

No. It can be cheaper at the purchase-order line, but the decision should use landed cost plus validation hours, spare inventory, duty, warranty risk, and controller-integration time.

What makes the tool return inconclusive?

The main triggers are missing documentation, unknown tier-one/BOM traceability, high-temperature rare-earth exposure, and boundary conditions such as heavy payload or high annual volume.

Which evidence should be requested first?

Start with full datasheet, torque-speed curves, thermal derating method, brake data, encoder protocol, EMC test scope, safety-function claims, magnet family, and traceability declaration.

Can a supplier certificate replace system validation?

No. It can reduce the workload, but AMR safety validation remains a system task involving the drive, controller, brakes, sensors, software, operating zone, and foreseeable misuse.

How should UFLPA risk be handled?

For U.S. imports, request supplier-chain mapping and forced-labor due-diligence evidence before production sourcing. Unknown traceability should stop the commercial decision.

When is a local service plan mandatory?

It is mandatory for scale deployment, 24/7 sites, outdoor use, or fleets where a drive-unit failure stops revenue operations. Spare drives and diagnostic access need to be priced.

Are CANopen and EtherCAT enough for compatibility?

They are a good start, but the integration check still needs PDO/SDO mapping, emergency objects, CiA 402 behavior, safety I/O wiring, firmware update policy, and diagnostics.

What should be done for EU deployments?

Build the evidence pack around machinery compliance, ISO 3691-4 truck-system validation, functional-safety claims, and the EU responsible operator/importer obligations.

Decision Report: China Drive Unit Sourcing

The tool gives a first-pass decision. The report below explains which evidence changes the decision, what remains uncertain, and where AMR integrators should stop before ordering.

Price-only quotes are not enough

Treat the public 30-50% cost-saving claim as unverified until a landed quote includes duty, freight, warranty stock, integration hours, and evidence-pack review.

C2C3

Magnet composition is now a sourcing gate

High-temperature traction modules can depend on Dy/Tb-enhanced NdFeB. If the supplier cannot disclose magnet family and export-license exposure, the answer should be inconclusive.

Compliance follows the whole vehicle

A drive-unit CE logo does not close the AMR safety case. The integrator still needs hazard analysis, PDS safety-function evidence, and truck-system validation.

C5C6C7

U.S. readiness needs import traceability

For U.S. programs, HTSUS classification, Section 301 exposure, and UFLPA traceability should be cleared before production purchase orders.

Evidence Request List

Evidence	Why it matters	Stop signal
Torque-speed and thermal derating curves	Confirms continuous duty beyond brochure peak torque.	Only peak torque or short-duration data is provided.
Brake, encoder, and firmware release history	Reduces integration surprises during fleet debugging.	Firmware changes are undocumented or locked by reseller.
EMC, ingress, vibration, and safety-function scope	Separates component claims from vehicle-level validation.	Certificate does not match exact model or firmware.
Magnet family and material-origin statement	Screens rare-earth export-control and traceability risk.	Supplier will not disclose magnet composition.
HTSUS, tariff, and forced-labor trace pack	Protects U.S. launch dates and landed-cost assumptions.	Importer cannot support CBP evidence requests.

Supplier Profile Comparison

Profile	Good fit	Main risk	Commercial rule
Export-focused manufacturer	Pilot or controlled scale program.	Higher quote, but stronger evidence pack.	Shortlist if test scope matches exact SKU.
Factory-direct supplier	Prototype and cost discovery.	Documentation can trail product changes.	Use with sample audit and firmware freeze.
White-label trading company	Spot replacement only when source is known.	Traceability, warranty, and firmware ownership.	Reject for scale unless OEM chain is disclosed.

Scenario Matrix

Scenario	Decision	Minimum next step
800 units/year, pilot fleet, export-focused supplier, full test reports	Proceed to engineering validation.	Sample test against duty cycle and controller stack.
Scale order, U.S. market, unknown BOM traceability	Hold commercial purchase order.	Resolve HTSUS, UFLPA, magnet, and supplier-chain evidence.
EU deployment with STO/SLS claims and datasheet-only evidence	Treat safety claim as unproven.	Request IEC 61800-5-2 evidence and vehicle-level validation plan.
Outdoor AMR with custom protocol and no local spare plan	High operational risk.	Add local service stock, firmware access, and ingress test evidence.

Risk Ladder

StopNo BOM traceability, no magnet disclosure, or mismatched certificate.

Limitations

This page is a sourcing screen, not a tariff ruling, compliance certification, or product approval.

Public sources do not prove a specific supplier's cost, material origin, or certificate scope. The final decision must use SKU-level evidence and your actual import route.
