How to Qualify an ESD Garment Laundry Supplier
A Practical QA & Operations Checklist for Manufacturers
Selecting a laundry provider for ESD garments should not begin with one question:
“What is your price per garment?”
Price matters, but an ESD garment program can also involve manufacturer care instructions, static-control requirements, weekly garment availability, sorting, packing, exception handling, QA procedures and business continuity.
A supplier that can wash a garment once is not necessarily a supplier that can operate a reliable garment program every week.
For Operations, Procurement, QA and ESD teams, the better question is:
Can this supplier repeatedly process and return our garments according to the requirements of our factory?
This checklist is designed to help manufacturers evaluate that question before approving a laundry provider, launching a pilot or moving a recurring garment program from one supplier to another.
What This Checklist Is Designed to Evaluate
The objective is not to determine whether a laundry provider is “good” or “bad” in general.
The objective is to determine whether the supplier is suitable for your specific garment program.
The evaluation should consider four areas:
1. Garment Compatibility
Can the supplier process the actual garments according to manufacturer and factory requirements?
2. Process Control
Can the supplier reproduce an agreed washing, drying, sorting and packing process?
3. Operational Reliability
Can enough garments be returned on time every service cycle?
4. QA and ESD Requirements
Are responsibilities for garment inspection, electrical verification, exceptions and documentation clearly defined?
A supplier qualification should address all four.
Step 1: Define the Garment Before Evaluating the Laundry
Do not begin supplier qualification with the generic description:
“We have ESD coats.”
Collect the actual garment information.
For each garment model, identify where possible:
-
manufacturer
-
model
-
fabric composition
-
garment construction
-
conductive or dissipative components
-
care label
-
permitted wash temperature
-
permitted drying conditions
-
prohibited chemicals
-
restrictions on bleach
-
restrictions on fabric softeners
-
recommended garment life or laundering limitations, if specified
-
relevant ESD characteristics
-
cleanroom requirements, if applicable
Different ESD garments may require different processes.
A supplier should therefore qualify the actual garment, not simply the category “ESD clothing”.
Step 2: Determine Whether the Garment Is ESD, Cleanroom or Both
This distinction should be made early.
ESD Garment
An ESD garment is used as part of an electrostatic-control program.
Its construction may include conductive or static-dissipative materials.
Cleanroom Garment
A cleanroom garment is used where contamination or particle control is part of the production environment.
ESD Cleanroom Garment
Some facilities use garments that must satisfy requirements from both systems.
This distinction matters because:
ESD performance and cleanroom cleanliness are not the same requirement.
A laundry process suitable for an ESD garment does not automatically qualify as a specialized cleanroom decontamination or sterile process.
Likewise, a cleanroom garment process does not automatically prove that the garment continues to meet the electrical requirements of an ESD control program.
If both requirements exist, both must be defined during supplier qualification.

Step 3: Separate Laundering from Electrical Verification
This is one of the most important questions in ESD garment management.
Laundry is not automatically an electrical performance test.
IEC 61340-4-9:2024 provides test methods for evaluating the electrical resistance of garments containing conductive or static-dissipative components used for electrostatic-discharge control.
ANSI/ESD STM2.1 is technically equivalent to IEC 61340-4-9.
If your ESD control program requires periodic verification of garments, define separately:
-
which test method is required
-
which garments are tested
-
test frequency
-
acceptance criteria
-
responsibility for testing
-
documentation requirements
-
rejection criteria
-
what happens when a garment fails
Do not leave this responsibility ambiguous.
A factory should know whether:
the laundry supplier washes only
or whether:
laundering and electrical verification are provided through a separately defined arrangement.
Those are different services.
Step 4: Review the Washing Process
Ask the supplier how a process is selected for a new garment.
Good supplier qualification questions include:
-
Do you review manufacturer care instructions?
-
How is the wash temperature selected?
-
How is detergent selected?
-
Are chemical restrictions documented?
-
How are different garment models separated?
-
Can customer-specific instructions be incorporated?
-
How is a process changed if the garment manufacturer updates its instructions?
-
Who approves exceptions?
Be cautious if the answer is:
“We use the same ESD wash for everything.”
Different manufacturers and garment constructions may have different requirements.
The supplier should be able to explain how the process is connected to the garment specification.
Step 5: Evaluate Detergent and Chemical Restrictions
Cleaning effectiveness is only one consideration.
The factory should also know whether the products and treatments used are compatible with the garment.
Ask:
-
Which detergent is used?
-
Is fabric softener used?
-
Is bleach used?
-
Are stain-removal chemicals used?
-
Are different chemicals used for exceptional items?
-
Are manufacturer restrictions reviewed?
-
Can a customer define prohibited chemicals?
For ESD garments, stronger treatment should not automatically be considered better treatment.
The objective is to clean the garment while staying within the approved maintenance requirements.
Step 6: Define How Stains and Exceptional Garments Are Handled
Industrial garment loads are rarely identical every week.
Some garments may arrive with:
-
food stains
-
body oils
-
collar contamination
-
biological stains
-
production-related contamination
-
unusual dirt
-
physical damage
A supplier qualification should establish what happens to these items.
Possible classifications include:
Standard Garments
Processed according to the normal program.
Stain-Treatment Garments
Require additional treatment before the standard process.
Exceptional Garments
Require inspection or customer approval before further processing.
Damaged Garments
Separated for review rather than automatically returned to use.
Ask the supplier:
How will we know when a garment did not follow the standard workflow?
Exception management should be part of the service specification.
Step 7: Evaluate the Drying Process
Drying should be treated as part of garment processing, not merely the final machine cycle.
There are two requirements that must work together.
Protect the Garment
Drying temperature and conditions must remain compatible with the garment specification.
Return the Garment Fully Dry
A garment should not be packed while meaningful residual moisture remains.
Moisture inside a sealed bag, storage container, locker or garment-distribution system can create operational problems including:
-
unpleasant odor
-
microbial growth
-
damp garments reaching employees
-
in severe cases, mold
Ask:
-
What drying limitations are followed?
-
How does the supplier determine that garments are ready for packing?
-
What happens if a garment remains damp?
-
Are garments allowed to cool or finish drying before enclosed packing?
The objective is:
complete drying without unnecessarily exposing the garment to unsuitable conditions.
Step 8: Define Receiving, Counting and Sorting
For a factory using hundreds of garments, sorting can become as important as washing.
Before approving the supplier, define:
-
how garments are received
-
whether garments are counted
-
how garment types are separated
-
whether sorting is required by size
-
whether sorting is required by employee
-
whether sorting is required by department
-
how exceptional garments are identified
-
how lost or unidentified garments are handled
The correct sorting method depends on the customer's internal garment-distribution system.
Possible structures include:
By garment type
By size
By employee
By department
By production area
The supplier should return garments in a format that reduces additional work at the factory.
Step 9: Review Packing Requirements
Packing should also be defined before routine service begins.
Ask whether the factory requires:
-
bulk packing
-
packing by size
-
packing by department
-
grouped packing
-
individual garment packing
-
identification labels
-
preparation for garment lockers
-
preparation for automated garment-distribution systems
A good laundry process can still create problems if hundreds of clean garments return in a format that the factory cannot efficiently distribute.
The return format should be part of supplier qualification.
Step 10: Evaluate Weekly Capacity
Do not qualify a supplier only on the volume handled during the first pilot.
Ask:
Can the supplier handle our normal weekly quantity repeatedly?
Then ask the more important question:
What happens if our volume increases?
Define:
-
normal garments per week
-
expected seasonal variation
-
maximum likely volume
-
emergency demand
-
available garment inventory
-
required turnaround
-
frequency of collection
For example, a factory processing 500 garments weekly should not qualify a supplier based only on a successful test involving 20 garments.
A small pilot can prove process compatibility.
It does not automatically prove full operational capacity.
Capacity should be evaluated separately.
Step 11: Examine the Collection and Return Cycle
Recurring industrial laundry is a logistics system.
A typical weekly cycle may look like:
Clean garments returned → used garments collected → processing → sorting and packing → next return
The supplier should understand:
-
collection day
-
collection time
-
return day
-
turnaround expectations
-
factory receiving hours
-
holidays
-
shutdowns
-
emergency changes
-
communication procedures
For Operations, predictable logistics can be just as important as wash quality.
Step 12: Ask What Happens During an Unexpected Volume Increase
Business continuity should be part of supplier qualification.
Ask:
-
What happens if volume increases 25%?
-
What happens if it doubles?
-
Is extra processing capacity available?
-
Can additional collection be arranged?
-
What happens if normal transportation is disrupted?
-
How are customers prioritized during periods of unusual demand?
Industrial environments are not always predictable.
Production can increase.
Staffing can change.
Emergency conditions can affect garment consumption.
A recurring supplier should have an answer for situations outside the normal weekly cycle.
Step 13: Define QA Responsibilities
A supplier qualification should make responsibilities clear.
Questions for QA may include:
-
Who approves the process?
-
Who controls garment specifications?
-
Who approves changes?
-
How are nonconforming garments handled?
-
What records are required?
-
What is the rejection process?
-
Who communicates exceptions?
-
Are manufacturer instructions retained?
-
Are customer-specific work instructions used?
-
How often should the program be reviewed?
The objective is not unnecessary paperwork.
The objective is to prevent situations where responsibility becomes unclear after a problem occurs.
Step 14: Define Change Control
Once a recurring program is working, changes should not happen casually.
Examples include:
-
new garment model
-
new fabric
-
manufacturer change
-
new detergent
-
altered washing temperature
-
different packing method
-
new stain treatment
-
new production department
-
increased quantity
-
changed ESD requirements
Ask:
What happens when something in the approved process changes?
Depending on the importance of the change, it may require:
-
document review
-
QA approval
-
new pilot
-
new garment testing
-
updated process instructions
Step 15: Decide What Documentation You Actually Need
Documentation requirements should match the risk and operating environment.
Possible records include:
-
garment specification
-
care instructions
-
agreed laundry procedure
-
service schedule
-
packing specification
-
exception procedure
-
supplier contact
-
pilot results
-
electrical verification records, where required
-
QA approval
A supplier should not invent unnecessary documentation simply to look sophisticated.
But when documentation is important to the customer, it should be clearly defined before service begins.
ESD Laundry Supplier Qualification Scorecard
A simple internal scorecard can make supplier comparisons more objective.
| Qualification Area | Suggested Weight |
|---|---|
| Garment/specification understanding | 15 |
| Washing-process compatibility | 10 |
| Drying process | 10 |
| Sorting and packing capability | 10 |
| Weekly capacity | 15 |
| Collection and return logistics | 10 |
| QA/process discipline | 10 |
| Exception handling | 5 |
| Business continuity | 10 |
| Pilot capability | 5 |
| Total | 100 |
The weighting should be adjusted to your factory.
For example, a facility with highly complex employee-specific sorting may increase the importance of garment identification and sorting.
A facility with limited garment inventory may assign a higher weight to turnaround and business continuity.
20 Questions to Ask a Potential ESD Laundry Supplier
Before approving a supplier, consider asking:
-
Do you review the actual garment model before routine service begins?
-
Do you work according to manufacturer care instructions?
-
How do you select washing temperature?
-
How do you select detergent?
-
How do you manage chemical restrictions?
-
How do you handle difficult stains?
-
What happens to damaged garments?
-
How do you ensure garments are dry before packing?
-
Can you sort by size?
-
Can you sort by employee or department?
-
Can garments be individually packed if required?
-
How are exceptional garments identified?
-
What weekly quantity can you support?
-
What happens if our quantity increases unexpectedly?
-
What is the collection and return cycle?
-
Can you work according to a customer QA procedure?
-
How are process changes approved?
-
Do you provide electrical garment verification, or is that a separate responsibility?
-
Can we begin with a pilot?
-
Can you operate as a backup supplier before we move the full program?
If the supplier cannot clearly answer these questions, the factory may not yet have enough information to approve a recurring program.
Warning Signs During Supplier Evaluation
Several answers should trigger additional questions.
“All ESD garments use the same process.”
Not necessarily.
Manufacturer and garment requirements should be reviewed.
“If the stain is difficult, we simply use stronger chemicals.”
That may conflict with garment-care requirements.
“The dryer program is automatic, so drying is not an issue.”
The relevant question is whether garments are appropriately dried before packing.
“Electrical testing is included because we wash ESD garments.”
Ask exactly what test is being performed, according to which method, by whom and with what acceptance criteria.
Laundry and electrical verification are separate activities.
“We can handle any quantity.”
Ask for evidence of recurring operational capacity.
“We don't need a pilot.”
For a large or technically sensitive garment program, a pilot can reduce risk for both parties.
How to Structure an ESD Laundry Pilot
A pilot should be small enough to control but large enough to produce useful information.
Before starting, define:
Garment Model
Which exact garment will be evaluated?
Quantity
How many items will enter the pilot?
Process
Which laundering and drying requirements apply?
Sorting
How should garments return?
Packing
How should processed garments be packed?
Timing
When are garments collected and returned?
Exceptions
What happens to stained or damaged garments?
QA Review
What will the customer inspect?
Electrical Verification
If required, when and how will garment performance be tested?
Success Criteria
What must happen for the pilot to be considered successful?
After several defined service cycles, Operations and QA can review the result before expanding the program.
Why One Successful Pilot Cycle Is Not Always Enough
The first cycle can confirm that a process is technically possible.
A recurring supplier must prove something more:
repeatability.
A better evaluation may include several cycles so the customer can see:
-
whether timing remains consistent
-
whether sorting remains accurate
-
whether packing remains consistent
-
whether communication works
-
how exceptions are handled
-
whether the process is stable from week to week
A supplier program becomes valuable when it stops depending on improvisation.
Should the Existing Supplier Be Replaced Immediately?
Not necessarily.
A manufacturer can qualify another laundry provider as a backup supplier before changing the primary supplier.
This may be useful when:
-
the existing provider has limited spare capacity
-
the factory requires business continuity
-
production volumes are increasing
-
another geographic route is needed
-
one garment group requires different handling
-
management wants an approved alternative available
The new supplier can first demonstrate performance on a limited program.
The customer can then decide whether to:
-
keep the supplier as backup
-
split volume
-
transfer a specific garment category
-
gradually expand the program
-
move the full service
Supplier qualification does not have to be an all-or-nothing decision.
Evidence Is More Important Than Claims
When evaluating a laundry provider, ask for evidence of recurring operations.
Useful evidence may include:
-
years of recurring service
-
typical weekly volumes
-
examples of sorting complexity
-
experience with customer-specific procedures
-
experience operating with QA requirements
-
examples of handling increased demand
-
pilot methodology
-
recurring collection and delivery experience
A supplier does not necessarily need to disclose confidential customer names.
Operational evidence can still demonstrate whether the company has experience managing recurring industrial programs.
For a detailed example:
Industrial Garment Laundry Case Study – Recurring Weekly Service
Maayan's Approach to Supplier Qualification
At Maayan, we prefer not to begin a new ESD garment program by asking a factory to move its entire garment inventory immediately.
The first step is usually to understand:
-
the garment
-
manufacturer instructions
-
weekly quantity
-
factory location
-
sorting requirements
-
packing requirements
-
QA requirements
-
ESD requirements
-
current service cycle
If there is a potential fit, the next stage can be a defined pilot or backup-supplier evaluation.
The objective is to determine whether a repeatable operational process can be built before expanding the relationship.
