How to Avoid Counterfeit Industrial Automation Components
Table of Contents
A convincing enclosure or intact carton cannot replace those controls. The objective is to prevent a questionable PLC, HMI, drive, sensor or power supply from reaching a machine simply because it arrived on time.
For purchasing teams, maintenance departments and machine builders, the following approach turns counterfeit prevention into a repeatable process.
Understand What You Are Trying to Prevent
Counterfeit prevention involves more than spotting a completely imitation product. Buyers also need to identify misrepresented condition and uncertain product history.
Schneider Electric explains that refurbished products can originate as legitimate equipment but retain original labels after alteration. Its guidance also describes instances of relabeling to make products appear new. Schneider Electric: Awareness and actions against counterfeits
Keep these purchasing questions separate:
| Question | What the answer establishes |
|---|---|
| Who manufactured the component? | Its claimed origin |
| Has it been used, repaired or modified? | Its condition and history |
| Through which channel was it supplied? | Its sourcing route |
| Does the exact version meet the application requirements? | Its suitability |
A disclosed refurbished part and a refurbished part sold as new present different purchasing situations. Likewise, genuine origin does not establish that a component is the correct replacement.
Define these requirements before requesting quotations. Otherwise, suppliers may offer materially different products under the same description.
1. Approve the Supplier Before Approving the Order
Maintain a supplier record that identifies the legal selling entity, business address, contact details and approved scope of supply.
Where a company claims manufacturer authorization, confirm the claim independently through the manufacturer’s locator or regional office. Check the exact company and relevant product scope rather than relying on a logo or a certificate supplied by the seller.
Rockwell Automation specifically recommends independent validation of authorization claims. It also advises machine buyers to verify the sourcing of Rockwell products incorporated into purchased equipment or solutions. Rockwell Automation: Gray Market and Counterfeit Product
That second point matters for machine builders and end users: components can enter your facility inside a completed control cabinet, not just through a spare-parts order.
As a practical purchasing control, record:
- Who checked the supplier and when.
- Which brands or product categories were reviewed.
- What sourcing evidence was available.
- Any restrictions or unresolved questions.
- When another review is required.
Previous satisfactory deliveries are useful history, but each new order should still meet its stated requirements.

2. Put Clear Requirements in the Purchase Order
Descriptions such as “original quality” or “same as original” leave too much room for interpretation.
Specify the manufacturer, complete part number, quantity and required condition. Include revision requirements when engineering has identified them as necessary.
For an order that requires new, unused components, the following is an example of purchasing language to adapt:
Supply the exact manufacturer and part reference stated in the order, in new and unused condition. Disclose any refurbishment, repair, modification, prior installation or packaging replacement before acceptance. No substitutions without written approval. Provide the agreed traceability records and identify each shipment against this purchase order.
Agree separately on the inspection period and the process for handling discrepancies.
Also distinguish the supplier’s warranty from manufacturer coverage. Ask who provides support, what terms apply and whether software or firmware access is included where relevant. A commercial warranty promise is not evidence of authenticity.
3. Create an Exception Process for Urgent Purchases
A stopped machine creates pressure to accept the first available offer. Establish an emergency purchasing process before that situation occurs.
When normal supply is unavailable, document:
- The exact component required and the consequence of waiting.
- The alternative supplier and evidence available.
- Any unresolved questions about origin or condition.
- Who can approve the purchase.
- What must be resolved before installation.
Purchase approval and installation approval should be separate decisions when evidence is incomplete. Paying for a urgently needed component should not automatically release it for use.
For safety-related applications, involve the responsible engineer before accepting an alternative source or replacement. Availability alone does not establish suitability.
Longer-term prevention can include reviewing critical spares, obtaining lifecycle information and planning replacements before an emergency. These are inventory decisions to make according to the plant’s equipment and downtime exposure.

4. Ask for Evidence Linked to the Actual Shipment
General company brochures and catalogue photographs say little about the goods being offered.
Request evidence proportionate to the order, such as photographs of the proposed stock, a written condition statement and available sourcing records. Link those records to the quotation, purchase order or shipment.
Use warning signs to trigger questions—not automatic counterfeit verdicts:
| Observation | Useful follow-up |
|---|---|
| A price is substantially below comparable offers | Check whether condition, version and included services differ |
| The seller provides only catalogue images | Request photographs of the proposed stock where inspection evidence is required |
| Supplier names differ across documents | Ask for an explanation of the entities involved |
| Product condition is described inconsistently | Obtain one clear written condition statement |
| The offered reference changes during negotiation | Require engineering review before accepting a substitution |
| Traceability is weaker than agreed | Resolve the gap before accepting the shipment |
No universal discount percentage identifies a fake. Equally, a high price does not prove authenticity.
5. Inspect Deliveries Before They Become Available Stock
Create a receiving stage between delivery and release to the storeroom.
Record the shipment identity, compare the delivered references with the order and preserve relevant photographs. Keep incoming items associated with their purchase records rather than mixing them immediately with existing stock.
Inspect accessible surfaces for damage, inconsistent identification or signs that conflict with the declared condition. Do not dismantle sealed assemblies simply to look for counterfeiting.
Use the correct label reference
Security markings are product-specific. Rockwell Automation’s official guidance lists applicable products by manufacturing date and plant code, with some requirements applying only to carton labels. A marking expected on one product may therefore be inappropriate as a universal test. Rockwell Automation: Security and Anti-Counterfeit Product Labels
Compare against the manufacturer’s applicable information, not an unrelated online photograph. Record discrepancies precisely: a different part-number suffix is a factual observation; “the label looks fake” is an interpretation.
Understand the scope of digital checks
Use manufacturer registration or authentication tools where applicable, and retain the actual response.
Rockwell Automation provides an official Product Registration service and information on eligible products. Follow the program’s current instructions rather than assuming every component supports the same process. Rockwell Automation: Product Registration
Distinguish between a code that opens documentation and a manufacturer response that addresses product verification. Do not record a successful catalogue lookup as a stronger result than it provides.

6. Keep Suspect Components on Hold
An unresolved component needs a visible status and a responsible owner.
A practical internal workflow is:
| Status | Handling rule |
|---|---|
| Awaiting inspection | Keep separate from available stock |
| Evidence under review | Prevent issue to a machine or project |
| Accepted | Record the basis for release |
| Rejected or confirmed counterfeit | Segregate and follow the agreed return or reporting process |
Preserve packaging, photographs, identifiers and supplier correspondence while the issue is investigated. If related units came from the same shipment, review whether they also require a hold; do not assume they are all affected without investigation.
For Rockwell products, the manufacturer directs authenticity enquiries to an authorized distributor or sales office, which can involve its Brand Protection team where necessary.
If a suspect component has already been installed, involve the responsible maintenance or safety personnel to plan the response. Avoid improvised removal from operating equipment.
7. Preserve Traceability After Acceptance
Counterfeit prevention should continue after incoming inspection.
As an internal control, connect the accepted item to its purchase order, receipt record and eventual stock location or machine. Retain unit identifiers where available and applicable; do not assume every printed code is a unique serial number.
When a component returns from a machine or repair provider, review its status before putting it back into stock. A genuine unit that has been installed should not silently return to a bin designated for new, unused parts.
Useful process measures include:
- Receipts with complete required records.
- Emergency purchases outside normal sourcing arrangements.
- Unresolved inspection holds and their age.
- Repeat discrepancies associated with a supplier.
These measures show whether purchasing controls are being followed. They should not be presented as counterfeit detection rates unless cases have actually been confirmed.
Frequently Asked Questions
A functional test establishes what the component did under the conditions tested. It does not independently establish manufacturer origin, unused condition or the absence of undisclosed modifications.
Keep engineering acceptance and authenticity review as separate records. Do not use a production machine as an authenticity test bench.
One sample cannot establish the identity and history of every other unit.
Set the inspection scope according to the application, supplier evidence and shipment consistency. Where individual identifiers exist, retaining them can help connect later findings to particular units.
Ask the manufacturer about lifecycle status and available support, then establish the offered item’s condition and sourcing evidence.
A discontinued reference does not remove the need for verification. If the evidence cannot meet your acceptance requirements, ask engineering to assess another supported route rather than treating urgency as proof of suitability.
