What Should Be Included in a Supplement OEM Quality Agreement?
For supplement brands working with an OEM manufacturer, agreeing on the formula, price, MOQ and lead time is only part of the preparation for commercial production. Both parties also need to understand who is responsible for quality decisions, how changes are managed and what happens when a batch does not meet the agreed specifications.
A Quality Agreement helps define these responsibilities before routine manufacturing begins. For overseas brands, it is particularly useful when product development, manufacturing, testing and market distribution involve different organizations.
ULTRA-NUTRA AU supports global supplement brands through Australian-based project coordination and certified China-based manufacturing capabilities. Clear quality responsibilities help support consistent manufacturing, testing, documentation and long-term supply.
Why Does a Supplement OEM Project Need a Quality Agreement?
A manufacturing contract usually focuses on commercial terms, such as product specifications, pricing, order quantities, delivery schedules and payment conditions. A Quality Agreement addresses a different question: How will the parties manage quality responsibilities throughout the product lifecycle?
For example, a brand may assume that the manufacturer will notify it before changing a critical raw material supplier. The manufacturing facility may follow its internal change-control process without knowing that the customer requires prior written approval. Even when both parties have established quality procedures, unclear expectations can create problems.
A Quality Agreement helps close these gaps by documenting responsibilities, communication requirements and approval points. It does not replace the manufacturing contract, product specifications or the manufacturer’s quality system. Instead, it clarifies how the parties will work together within those arrangements.
The level of detail should reflect the product, target market, manufacturing model and associated risks. A straightforward stock product may require a simpler arrangement than a customized formula involving proprietary ingredients, multiple external service providers and market-specific documentation.
A Quality Agreement also builds on the initial process of qualifying a supplement manufacturer, defining how quality responsibilities will be managed after supplier selection and as the OEM partnership moves into production.
What Should a Quality Agreement Cover?
The agreement should focus on responsibilities that could affect product quality, regulatory compliance or the ability to maintain consistent supply.
Raw Material Approval and Supplier Changes
The agreement should clarify who approves raw material specifications and whether the brand must approve critical ingredients or suppliers before use.
This is especially important for botanical extracts, standardized ingredients and branded raw materials, where differences in source, marker levels, carrier content or specifications may affect the finished product. If a supplier discontinues an ingredient or proposes a replacement, the parties should understand how equivalence will be assessed and when customer notification or approval is required.
The objective is not to require brand approval for every routine purchasing decision. It is to establish appropriate controls for changes that could affect the product’s agreed quality attributes.
Testing, COAs and Batch Release
A Quality Agreement should explain which party is responsible for each required test, how results are reviewed and who has authority to make the manufacturing batch-release decision.
Some tests may be performed by the manufacturing facility’s laboratory, while others may be assigned to qualified third-party laboratories. Where external laboratories are involved, the agreement should clarify who selects or approves the laboratory, coordinates sample submission, reviews results and manages unexpected findings.
Critical manufacturing, packaging or testing activities may also be outsourced. In these cases, the agreement should clarify the relevant supplier qualification, oversight, documentation and customer-notification responsibilities. Outsourcing an activity does not eliminate the need to define who oversees it.
Importantly, manufacturer quality release and customer acceptance are separate decisions where the project agreement requires both. The manufacturer’s designated quality personnel remain responsible for applicable manufacturing quality decisions. Additional brand approval or destination-market requirements should be defined separately, according to the contractual and regulatory framework.
Receiving a Certificate of Analysis (COA) does not automatically mean that every contractual or customer-specific requirement has been fulfilled.
Deviations, OOS Results and Corrective Actions
Manufacturing deviations and out-of-specification (OOS) results require a defined process for investigation, documentation and disposition.
The agreement should establish how significant quality events are communicated, who leads the investigation, how corrective and preventive actions (CAPA) are managed and who is responsible for the final disposition of the affected batch under the applicable quality system.
For example, if a finished-product assay result falls outside the agreed specification, the parties should not rely on informal email exchanges to decide what happens next. The result should be investigated and documented before the batch disposition is determined.
The agreement should also clarify how customer complaints, potential product-quality issues and events that may require product withdrawal or recall are escalated.
Change Control and Customer Approval
Changes to raw materials, specifications, manufacturing processes, testing methods or packaging can affect an established product even when a change appears operationally minor.
Changes should be assessed according to their potential impact on product quality, specifications, regulatory compliance and manufacturing consistency. Major or critical changes—such as changes to key ingredients, approved specifications or critical manufacturing processes—may require prior written customer approval, as defined in the Quality Agreement. Lower-risk changes may be managed through documented internal change control and customer notification where required.
The agreement should define which changes require internal documentation, customer notification or prior written approval. It should also specify the supporting information needed, applicable notification and response timelines, and whether additional testing, comparability assessment or stability evaluation is necessary before implementation.
Timelines should be agreed according to the type of change and its potential impact rather than applying one fixed deadline to every situation. Urgent quality events may require a separate escalation process.
This is particularly important for mature supplement brands that need to maintain product consistency across repeated commercial orders.
Documentation, Traceability and Recall Support
The parties should clarify which records the manufacturing facility maintains, how relevant documents are made available to the brand and how long records are retained under applicable requirements and agreements.
The agreement should also define responsibilities for batch traceability, complaint investigation and product withdrawal or recall activities where applicable. If a market issue occurs, both parties need to understand how affected raw materials and finished batches can be identified, who coordinates communication and how supporting information will be shared.
Not every internal manufacturing record needs to be routinely supplied to the customer. However, the agreement should identify which records must be provided, which must be retained by the manufacturing facility and how relevant records can be accessed when a quality investigation or regulatory request requires them.
For projects involving an existing product or manufacturing process, the Quality Agreement should also align with the relevant supplement manufacturing tech transfer checklist, so that documentation, testing responsibilities and change-control expectations are clear before commercial production.
Who Is Responsible for Each Quality Decision?
When an OEM project involves a brand, manufacturing facility, project coordinator and external laboratory, responsibilities can overlap unless they are defined in advance.
The following matrix is a practical starting point. Actual responsibilities should be confirmed in the project agreement and adjusted to the manufacturing model, target market and applicable regulatory requirements.
Quality activity
Brand / Customer
Manufacturing Facility / Quality Unit
ULTRA-NUTRA AU Project Coordination
External Laboratory
Raw material specifications
Defines requirements and approves where agreed

This matrix does not transfer the manufacturing facility’s quality-release responsibilities to the project coordinator, nor does it automatically transfer an importer’s or local responsible party’s legal obligations to another organization. Applicable duties depend on the product, destination market, legal framework and actual business arrangements.
The objective is to establish clear ownership while allowing the parties to cooperate efficiently.
Practical Quality Agreement Scenarios
A Quality Agreement becomes more useful when it explains how responsibilities work in real situations.
Scenario A: A critical botanical extract supplier changes.
The manufacturing facility should assess the proposed change against the approved specification and relevant quality risks. Supporting information may include the ingredient specification, marker levels, analytical results and a comparability assessment. ULTRA-NUTRA AU can coordinate the communication and documentation exchange, while the brand provides approval where the agreement requires it. Additional testing or stability evaluation should be determined according to the change’s potential impact.
Scenario B: A finished-product test returns an OOS result shortly before shipment.
The result should be managed through the applicable investigation and batch-disposition procedures. The manufacturing facility’s designated quality personnel determine the appropriate manufacturing quality disposition. The brand should be notified according to the agreed escalation requirements, and shipment should not proceed where applicable release conditions remain unmet. A commercial deadline does not override the required quality process.
Scenario C: A customer complaint may require batch traceability or recall support.
The parties should follow the agreed complaint and escalation process, identify potentially affected batches and share relevant information. The manufacturing facility supports manufacturing records and traceability, while the brand, importer or other responsible party fulfills its assigned market-facing and regulatory obligations. ULTRA-NUTRA AU can coordinate communication and document collection within its agreed project role.
These scenarios illustrate why responsibilities, notification timelines, approval requirements and records should be established before a quality event occurs.
When Should the Quality Agreement Be Finalized?
The agreement is best discussed during supplier qualification and finalized before routine commercial production begins. This allows both parties to resolve differences in expectations before they become urgent production or release issues.
It should be consistent with the product specifications, testing requirements, manufacturing contract and applicable regulatory obligations. If the project involves a new formulation, technology transfer, outsourced activities or market-specific requirements, those details should be considered during preparation.
A Quality Agreement should be proportionate to the project rather than treated as a universal template. Product classification, manufacturing arrangements, target markets and customer requirements can all affect the appropriate allocation of responsibilities.
The agreement should also identify the process for reviewing and updating responsibilities when the product, manufacturing arrangement or applicable requirements change.
A Practical Quality Agreement Review
Before signing, the brand and its manufacturing partner should be able to answer the following questions:
- Who owns each important quality activity and decision?
- Which raw material, process, specification or packaging changes require notification or prior approval?
- How are deviations, OOS results, complaints and potential recalls investigated and communicated?
- Which activities are outsourced, and how are those activities qualified and overseen?
- Which records and testing reports must be provided, retained or made available upon request?
- How are manufacturing release, customer acceptance and shipment requirements distinguished?
If these questions cannot be answered consistently by the parties, the agreement may need further clarification before commercial production begins.
