Becoming a Watlow Supplier
Watlow utilizes a documented process within our quality system that defines how to select, evaluate, and approve a
new supplier for Watlow. Objective criteria including quality system capability, process maturity, technical
excellence, delivery, services, value capabilities, and cost are all variables that the team assigned to select the
supplier will apply in determining the best partner, whether the supplier is a new or an existing Watlow supplier.
The Watlow supplier selection process is focused on finding strong partners, suppliers dedicated to superior
performance to the requirements defined in this manual, those willing to work with Watlow to ensure alignment to
and understanding of Watlow’s expectations, and those who desire a long-term mutually beneficial relationship.
Watlow reserves the right to conduct on-site audits/visits when needed, where the product supplied to Watlow is
manufactured, which shall include a supplier’s sub-tier supplier, as required.
6.0 Wat low’s Supplier Quality Management System Requirements
6.1 Health, Safety, and Environment
Watlow’s suppliers are expected to conform to all applicable governmental requirements and laws mandated

6.2 Quality Systems Management and Improvement
Watlow expects all suppliers to have Quality Management Systems (QMS) registered to the latest revision of
ISO9001, with IATF16949 registration preferred. Other internationally recognized QMS registrations may
also be acceptable.
However, if a supplier’s quality system is not registered, Watlow Supplier Quality Engineering and Sourcing
may approve the use, or continued use of the supplier, at their discretion following a detailed evaluation of the
systems that are in operation.
Any change in approval/registration status of a third-party registration by an accredited registrar must be
communicated to Watlow in writing, sent to your Watlow purchasing or quality contact as soon as the change
of status is known.
6.3 Business Continuity Planning
Watlow’s suppliers shall manage, review regularly, and maintain a Business Continuity Plan (BCP), which
shall document and prioritize the risks to their business and develop appropriate plans to mitigate, recover,
and replace lost capacity as the result of; equipment failure, labor issues, pandemics, natural disasters, fire,
raw material availability, sub-tier supplier issues, etc., to ensure an uninterrupted supply of products.
The BCP shall include a Recovery Time Objective (RTO), which shall be defined in the plan to recover to
80% capacity within four weeks and 100% capacity within six weeks.
6.4 Product Quality Planning
Watlow expects each of our suppliers to have systems in operation that will allow proactive assessment of the
risks to the quality of their products and applicable contingency plans.
This would include; requirement capture and review, engaging material suppliers, product and process
validation, and monitoring the manufacturing production processes to ensure stability and a quality product
output.

Training
The supplier shall have a documented training program for new and current employees. Training schedules
and records of training completion shall be maintained.
Watlow may also require suppliers to train to select Watlow procedures and requirements as business is
conducted with the supplier. Watlow will initiate the training when it is applicable.
6.6 Internal/Self Audits
The supplier shall have an internal/self-audit system in operation that assesses compliance with the
organization’s quality system elements, by their quality system registration requirements.
Audit and corrective action records shall be maintained.
Watlow may also require suppliers to execute self-QMS and Process audits periodically during the
relationship. When applicable, Watlow will initiate and request these audits be executed.
6.7 Corrective Action/Problem-Solving System
All Watlow suppliers are expected to have a Corrective Action System operational, which manages both
internal and supplier issues.
When Watlow submits a “Quality Issue” to a supplier, it can be either in the form of a “notification/quality
alert” or could be a request for “corrective action”.
When a corrective action is requested by Watlow, the supplier’s work and response shall follow the 8D
methodology and response submitted be in an 8D format of the supplier’s choosing, which must include the
following elements:
D1: Identify the Team and Plan
D2: Define the Problem
D3: Establish Containment Plan

D7: Identifying and Implement Preventative Action Plan
D8: Close and Monitor
Additional Requirements for completion of an 8D corrective action:
• D1-D3 shall be established within two working days following notification.
• D4-D5 shall be defined within 10 working days following notification, or as agreed by Watlow
• D6-D8 shall be completed per the supplier’s plan, or as agreed by Watlow
• The supplier shall apply the appropriate quality tool(s) to facilitate identifying “root cause” (e.g. Five
Why’s, Cause Chains, and Fishbone (5M+E) Diagrams) and evidence of this work shall be included in D4
of the 8D response.
The supplier shall be responsible for costs and management of sorting and containment of nonconforming
material, including the sorting of material at a Watlow or customer site if necessary.
6.8 Special Material Identification Requirements
When directed by Watlow, usually in the case of reworked or 100% inspection/sorting, the supplier may be
required to apply a label to the material’s packaging (ie. outer/inner shipping containers, bulk part packaging,
reel packaging, etc.) indicating the material has been verified to meet specifications before shipping to
Watlow.
The label applied must be of a size easily recognizable on the package it is placed and include information
which will be defined by Watlow.

Change Control and Communication
Watlow recognizes a continuous improvement philosophy encourages product changes, sourcing/subcontractor changes, and process and manufacturing improvements. However, to ensure against any
unforeseen impact on Watlow or its customers, Watlow expects our suppliers to have processes in place to
manage those changes and to recognize when their customers need to be involved before proceeding with
the implementation of the change.
Watlow has established a “Supplier Change Control and Communication Requirements Process”, Watlow
document #10-14866 (aka QSP-7.4.10). The latest version of the document can be found here:
https://www.watlow.com/en/resources-and-support/additional-support/supplier- requirements
This requirement document defines the level of communication and/or approvals needed for a variety of
changes affecting Watlow product supplied, including form, fit, function, and manufacturing process changes.
When there is a control level identified by Watlow on a drawing/print/spec or PO, “Supplier Change Control
and Communication Requirements” 10-14866 (aka QSP-7.4.10) applies to the item to be supplied.
If there is not a control level identified on the product drawing/print/spec or PO, the requirement of 10-14866
(aka QSP-7.4.10) does not apply to the item.
Training for all new suppliers is required, with annual refresher training required of select suppliers, who will
be notified by Watlow Supplier Quality Engineering as needed. The training material can also be found at the
link above.
6.10 Procurement Systems and Control
The supplier is expected to have a defined method of evaluating and approving new suppliers, involving
multiple functional resources, typically including purchasing, engineering, and quality in the process.
The supplier is expected to establish goals and monitor the performance of their suppliers to meet their goals
and take appropriate action when their suppliers fail to meet the goals established. Records of actions taken
shall be maintained.
The supplier shall also have a system to flow Watlow-defined requirements to the supplier’s sub-tier
suppliers as needed.
6.11 Prevention of Counterfeit Material
Watlow’s suppliers shall plan, implement, and control processes, appropriate to the supplier’s business and
product, for the prevention of counterfeit or suspect counterfeit material use and their inclusion in the
product(s) delivered to Watlow.

manufacturer’s recommendation.
6.14 Receiving/Incoming Inspections, In-Process Inspections, and Final Testing/Inspection
The supplier is expected to apply appropriate inspections and testing throughout their manufacturing process
to ensure customer and product requirements are met, with appropriate countermeasures defined to manage
nonconforming material.
6.15 Material Management and Control
The supplier is expected to maintain appropriate material storage and handling of raw materials, components,
and sub-assemblies throughout the manufacturing process and facility. This would include the storage and
handling of temperature, humidity, and electrostatic-sensitive materials.
First in First Out (FIFO) system of inventory management is expected to be in operation.
Material tracking systems shall be in place to track work in process (WIP) throughout the facility.
Material traceability systems shall comply with IPC-1782A (latest revision), Standard for Manufacturing and
Supply Chain Traceability for Electronic Products, Class/Level 1 (Basic) unless otherwise specified by
Watlow. For non-electronic materials, traceability to the manufacturer and their lot number is expected.
The supplier shall have a system of control of “nonconforming material”. This system must ensure
the segregation of material to minimize the risk of mixing into conforming material, and timely disposition of
nonconforming material (from the production floor and the facility, including return to supplier materials),
with records maintained.
The supplier shall have a system for Obsolescence Management in operation, which shall include an End Of
Life (EOL) identification procedure to detect potential material obsolescence, create a containment plan, and
comply with Watlow’s Supplier Change Control & Communication Requirements (Watlow document 10-14866,
as noted in section 6.9 of this document), where a 365-day advanced notice (or as early as possible) is
expected for any kind of material change request.
6.16 In Process Control
The supplier shall maintain systems that define how an operation (manufacturing and non-manufacturing
functions) are intended to function (i.e., standard operating procedures, work instructions, control plans, etc.)
and appropriate verification to ensure the output of each operation conforms to defined requirements.
Process Control and Manufacturing Documentation:
Manufacturers of Non-Custom, Shelf, Catalog, and similar items Watlow purchases which are
Manufactured according to the supplier/manufacturer specifications shall have:
• Manufacturing documentation defining how the item supplied is to be manufactured to ensure consistent
and repeatable product, conforming to the published specifications (ie. routers, travelers, work
instructions, control plans, etc.) is required.
Manufacturers of “Custom for Watlow” items, which are manufactured only for Watlow and for Watlow
specifications are expected to develop and maintain the following types of process control documentation,
which defines what and how the custom item is produced shall have:
• Design Records/Customer Specific Requirements
• FMEA (Failure Mode Effect Analysis)
▪ Process FMEA
▪ Design FMEA, if applicable
• Bill of Materials
• Change Records/Customer Approval Records (PPAP’s, FAI’s, PCN’s etc.)
• Control Plans (or comparable manufacturing documentation)
• Work Instructions supporting Control Plans
• Records (test, inspection, process, etc.) supporting Control Plans
• Sub-Tier Supplier Control Documentation (as applicable – prints, specifications, work instructions,
etc.)
6.17 Packaging and Shipping
In some cases, Watlow may define the packaging requirements and it is expected the supplier work with
Watlow to meet these requirements.
When the packaging is not defined by Watlow, the supplier is expected to package the product per their
internal standards. The resulting packaging shall always be sufficient to protect the product from damage
during normal shipping and handling to Watlow.
All products shipped to Watlow shall be identified with Watlow part number and revision if applicable on each
parcel shipped as well as a packing slip adhered externally to the parcel.
6.18 Lean Manufacturing
“Lean Manufacturing” or “Lean” is a culture of elimination of waste in the operation of a business without the
loss of productivity.
Watlow expects our suppliers to maintain a clean and organized workplace, be supportive of watlow’s lean
initiatives, and be open to learning how certain lean tools and techniques could also help their business
minimize waste and create a more efficient and productive environment.
7.0 Supplier Performance Expectations
7.1 Perfect Quality
The target shall always be zero non-conformances and zero supplier issue requests (notifications, SCARs).
Watlow’s supplier’s performance is monitored monthly and the supplier’s quality performance is
communicated quarterly to select Watlow suppliers, and other suppliers as required based on performance.
At Watlow’s discretion, a quality improvement plan may be requested if quality performance data trends
indicate declining performance, usually over a 3 to 6-month period, or performance trends at 20% over
established PPM targets for suppliers under a Long Term Agreement contract.
Specific quality performance and year-over-year improvement goals may be established at the discretion of
the Watlow Supplier Quality Engineer for any Watlow supplier.
Long Term Agreements and other procurement documents may also establish general performance
expectations and targets. However, any goal established by Watlow Supplier Quality Engineering shall take
precedence over any other stated quality performance targets.
Non-conforming material: Wat low’s suppliers are expected to address their quality issues as a priority at all
times to contain the issue and initiate appropriate containment and corrective/preventative action.
When supplied non-conforming material is discovered, or overall supplier performance is not acceptable,
Watlow may choose to:

• Request an RMA# and return any suspect product for credit with shipping costs paid by the supplier.
• Supplier Corrective Action Request (SCAR) (request for corrective and preventative action which
requires an 8D report or similar.
• Issue a Supplier Notification (awareness expected to trigger the supplier into appropriate
corrective/preventative action without needing to provide a report to Watlow)
7.2 Perfect Delivery
100% On Time Delivery “as promised” to Watlow (OTP) and 100% On Time Delivery to Watlow’s “request”
(OTR) is always the target.
Long Term Agreements and other documents may also establish general performance expectations and
targets. Watlow Sourcing may choose to establish other goals or improvement objectives for select suppliers
at their discretion.
Watlow measures On Time Delivery, by comparing the date at which an item is received on Watlow’s dock to
the date confirmed by the supplier (OTP), and the date requested by Watlow (OTR), on the Watlow purchase
order. If an item is delivered between the date on the purchase order (as promised date) and no more than
3 days prior, it is counted as an “on-time.”
Changes to purchase orders often occur during normal business. Our suppliers are strongly
encouraged to request an updated purchase order from Watlow whenever a change or modification is made
and agreed upon between the supplier and Watlow buyer. This can help ensure accurate data is in Watlow’s
system, vital for Watlow production planning and for analyzing a supplier’s on-time delivery performance.
At Watlow’s discretion, corrective action or an improvement plan may be requested if delivery
performance data trends indicate declining performance.
7.3 Responsiveness
Watlow expects our suppliers to be as “responsive” as possible whenever requests and inquiries of any kind
are submitted.
Regarding quality-related inquiries, an initial response (within 24 hours) is expected to acknowledge receipt of
the request and provide a plan to complete the request if necessary.
See “Corrective Action/Problem-Solving Systems” in section 6.7 of this document for expectations for 8D
Reporting timing related to the responsiveness expectation.
8.0 Supplied Part/Product Technical Requirements
8.1 Purchase Order
The Watlow purchase order will identify the part number, the drawing number, and the revision if applicable. The
purchase order may identify the supplier change control level if the part is subject to Watlow’s supplier
change control and communication.
The purchase order may have additional requirements for the product (e.g. certifications, change control
level, packaging, labeling, etc.) and shall be reviewed by the supplier before acceptance of the order.
Purchase Orders (PO) shall be confirmed by the supplier within 24 hours of receipt of the PO from Watlow.
Supplier Control Level and change communication
The “Supplier Control Level” is the part control level per 10-14866 (QSP-7.4.10) policy. When a change is
pending the affected item, the supplier is to cross reference the type of change versus the control level via
the table in the policy determines whether Watlow requires Notification or Approval before implementation
• If there is not a control level identified on the product drawing, or PO the requirement of 10-14866 (QSP7.4.10) does not apply to the part.
• When there is a control level identified “Supplier Change Control and Communication Policy” 10-14866
(QSP-7.4.10) applies.
Depending on the control level and type of change, 10-14866 (QSP-7.4.10) will define the actions required of the
supplier. Actions needed will be one of the following: no action, change notification to Watlow, or hold
implementation for Watlow approval.
You may find the change submission form, policy, and training presentation at the Watlow supplier
requirements website: https://www.watlow.com/en/resources-and-support /additional-support/supplierrequirements
8.2 Traceability
There may be traceability requirements on the PO or the drawing. In this case, the drawing and PO
requirements will override the traceability requirements defined in this manual. If no traceability
requirements are defined on the PO or part drawing, the requirements are as follows:
Each container, both master and minor containers (bag, box, etc) delivered to Watlow must be identified with
a manufacturer lot #. The format of the lot number is not critical. Some examples may be work orders, date
codes, etc. The number shall be traceable to the manufacturer’s raw material lot #’s, and process information,
including outside contractors, if any.
8.3 First Article Inspection Reports (FAIR)
A part manufactured to a drawing/Engineering specification provided to the supplier is considered “custom for
Watlow” and the supplier control level on the specification sheet will be a “3” or a “4”. For all custom parts, a
FAIR is required to be delivered with, or in advance of, part shipment for the first receipt from a supplier, and
for the first shipment of a new revision.
A typical First Article inspection should include:
• First Article Inspection Report complete with all dimensions verified and actual measurement recorded
and a positive acknowledgment of every general note on the engineering drawing, including a bubble
drawing numbering the features reported.
• Raw material certifications to applicable industry or manufacturer standards
• Subcontractor (i.e. plating, welding, PCB fabrication, cleaning, etc., certificates of conformance to
specified requirements
• Additional documentation, such as Process Control Plan, PPAP, or work instruction, as applicable
• Other types of data requested by Watlow, if applicable
Approval of FAIR by Watlow shall be considered the release for shipment of future products and the start of
production. If signoff by Watlow is required by the supplier, please contact the Watlow Buyer to assist.
The goal for all FAIRs is to ensure the requested information and data submitted by the supplier will allow for
Watlow approval the first time it is submitted.
8.4 Hazardous Materials
Hazardous Materials shall include an MSDS with the shipment. The container and product shall be labeled
per OSHA Hazard Communication Standard, 29 CFR 1910.1200 (HCS), which is in alignment with the United
Nations’ Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
8.5 Compliance Programs (RoHS, REACH, Conflict Minerals, UL, etc.)

When the compliance program is a requirement per PO or Drawing, it is the supplier’s responsibility to
ensure compliance. Evidence of compliance shall be available and furnished upon request. Certification of
compliance should be provided to Watlow with an FAI report on the first shipment.
Certifications, if needed, will be requested via the drawing or the PO.
8.6 Trade Compliance (for suppliers of foreign goods or suppliers exporting to the U.S.)
It is, by law, that for any foreign (non-U.S.) goods we must provide the U.S. purchaser with the proper country
of origin. For suppliers who are exporting to the U.S., the proper country of origin must be stated to the U.S.
Customs for admissibility, duty, and other reasons.
The supplier shall provide, upfront, a written and signed non-preferential certificate of origin, as well as,
include the origin on the invoice at the line item level.
Should the origin of a product change, the supplier shall provide an updated signed non-preferential
certificate of origin before shipping or invoicing for the affected part(s).
Discontinuation of product/services: Watlow requests a one-year notification of product or service
obsolescence. If this is not possible, Watlow requests a last-time buy option for a negotiated quantity of
material to secure a minimum of one year supply.
9.0 Exceptions to this Document
This document establishes the general expectations of watlow’s suppliers, which may or may not be defined
by other procurement documentation, such as purchase orders, terms and conditions, design
specification/drawing, supply agreements, or other specific contractual agreements with the supplier.
If there are any exceptions or additions to what this guide defines that are mutually agreed upon, those
details shall be defined in one of those documents noted above, or as otherwise agreed by Watlow.
