Quality Agreements: What Brand Owners Need to Know

A quality agreement is a written contract between a brand owner and a contract manufacturer that defines who is responsible for every quality decision in the production process. It is separate from the manufacturing agreement and covers testing, documentation, change control, and dispute resolution.

Most brand owners sign manufacturing agreements without a quality agreement in place. This is one of the most common and costly mistakes in the supplement industry. When a batch fails testing, when a customer complaint arrives, or when the FDA shows up, the quality agreement determines who is responsible and what happens next.

Dietary supplement manufacturers must comply with 21 CFR Part 111 (Current Good Manufacturing Practice for dietary supplements). This includes requirements for personnel, facilities, equipment, production, laboratory operations, and record-keeping.

Why You Need a Quality Agreement

Under 21 CFR Part 111, the person whose name appears on the product label is responsible for compliance. That person is you. Even if a contract manufacturer made the product, tested it, packaged it, and shipped it, you bear the regulatory responsibility.

A quality agreement makes this shared responsibility explicit. It defines what the manufacturer does, what you do, and what happens when something goes wrong. Without one, every quality problem becomes a negotiation instead of a defined process.

FDA inspection reports (483s) frequently cite failures in quality oversight between brands and their contract manufacturers. The most common: no written agreement defining testing responsibilities, no documented procedure for handling out-of-spec results, and no records of incoming material review.

Quality Agreement vs. Manufacturing Agreement

These are separate documents with different purposes. Mixing them creates confusion during quality events.

Key Sections of a Quality Agreement

Every quality agreement should address these areas. The detail level depends on your product complexity and the manufacturer's capabilities.

Raw Material and Component Specifications

  • Written specifications for every ingredient, excipient, and packaging component
  • Who approves incoming materials: the manufacturer, the brand, or both
  • Procedure for handling materials that don't meet specification
  • Requirements for supplier Certificates of Analysis

Testing Responsibilities

  • Which tests the manufacturer performs in-house
  • Which tests require third-party laboratory confirmation
  • Identity testing requirements per 21 CFR 111.75(a)
  • Finished product release testing and who makes the release decision

Change Control

  • Manufacturer must notify you BEFORE changing raw material suppliers
  • Notification required before equipment changes that affect product
  • Process changes require your written approval
  • Changes to testing methods require notification

Deviation and Out-of-Spec Handling

  • Written procedure for investigating out-of-spec results
  • Timeline for notifying you of deviations (24-48 hours is standard)
  • Who decides whether to release, rework, or reject a batch
  • Root cause analysis and corrective action requirements

Complaint Handling

  • How customer complaints about product quality are routed
  • Manufacturer's responsibility to investigate complaints related to manufacturing
  • Timeline and format for complaint investigation reports
  • Adverse event reporting responsibilities

Audit Rights

  • Your right to audit the manufacturer's facility with reasonable notice
  • Frequency of routine audits (annually is standard)
  • Access to batch records, testing data, and deviation reports
  • Response timeline for audit findings and corrective actions

Recall Procedures

  • Who initiates a recall and who manages the logistics
  • Cost allocation for recalls caused by manufacturing defects vs. design issues
  • Communication responsibilities during a recall
  • Manufacturer retains sufficient retention samples for investigation

Negotiating Your Quality Agreement

Most contract manufacturers have a template quality agreement. That template protects the manufacturer. Your job is to read every section and negotiate the terms that protect your brand.

  • Start with their template, then revise. Don't write one from scratch. The manufacturer's template reflects their actual processes. Revise it to add your requirements rather than creating a document that doesn't match how they operate.
  • Get your own quality person involved. If you don't have a quality team, hire a quality consultant to review the agreement. This is not a document for your business attorney alone. Quality agreements require regulatory expertise.
  • Define testing specifications, not just 'industry standard'. Vague language like 'meets industry standards' is unenforceable. Specify exact test methods, acceptable ranges, and limits for every ingredient and finished product parameter.
  • Require notification before changes, not after. The change control section is where most quality agreements fall short. A manufacturer who switches your vitamin C supplier without telling you has created a compliance risk you didn't consent to.
  • Include a retention sample clause. The manufacturer should retain samples from every batch for at least one year past expiration. These samples allow investigation if a quality issue surfaces after the product is on shelves.

Common Mistakes

These errors show up repeatedly in the supplement industry. Each one creates real risk during FDA inspections or quality events.

  • No quality agreement at all. The most common problem. Roughly 40 percent of emerging supplement brands operate without a formal quality agreement. When a batch fails, there is no documented procedure for resolution.
  • Signing the manufacturer's template without changes. Template agreements typically assign maximum quality responsibility to the brand and minimum responsibility to the manufacturer. Review every clause.
  • Combining quality and commercial terms. When pricing and quality terms share a document, commercial pressure can influence quality decisions. 'We'll accept the out-of-spec batch if you discount the next order' is a compliance failure waiting to happen.
  • No change notification requirements. A manufacturer changes an ingredient supplier to save cost. You don't find out until a customer reports the product tastes different. Or worse, until an identity test fails.
  • Vague dispute resolution. When a batch fails and both parties disagree on the cause, a quality agreement without clear escalation steps turns a quality event into a legal dispute.

When to Review and Update

A quality agreement is a living document. Review it at least annually and update it when conditions change.

  • After any product quality event or customer complaint
  • When the manufacturer changes equipment, processes, or key personnel
  • When you add new products or change formulations
  • After an FDA inspection of either your operation or the manufacturer's facility
  • When regulations change (new testing requirements, updated limits)
  • Before renewing the manufacturing contract for the next term
