Most supplement brands sign a manufacturing deal without a quality agreement — and never feel the gap until something goes wrong. Then a batch fails testing, or a retailer pulls the product, and the only question that matters is: who is responsible? Without a quality agreement, the answer is usually “you.” With one, it’s defined in advance, in writing.
The quality agreement is the least glamorous and most protective document in your contract. Here’s what it does and what yours must cover.
A quality agreement is a written document, separate from your commercial contract, that defines the quality responsibilities of both the brand owner and the contract manufacturer. It spells out specifications, testing, documentation, and — critically — who is accountable when a batch is out of spec, when a recall happens, or when a raw material is rejected.
The commercial contract covers price and volume. The quality agreement covers what happens when quality is on the line. You need both.
The FDA expects the brand owner to control quality, even when manufacturing is outsourced. If responsibilities aren’t documented, regulators — and courts — default to the firm whose name is on the label. A quality agreement is how you move from “we assumed they’d handle it” to “it is defined and signed.”
| Clause | Why It Protects You |
|---|---|
| Specifications | Defines exactly what “in spec” means for identity, potency, and purity |
| Testing responsibilities | Names who tests what, when, and by which method |
| Out-of-spec handling | Sets who investigates and who decides when a batch deviates |
| Documentation & CoAs | Guarantees you receive batch records and certificates |
| Change control | Stops the manufacturer from changing ingredients or process without your sign-off |
| Recall responsibility | Defines roles and cost-sharing if a recall is needed |
| Audit rights | Confirms you can inspect the facility and records |
Change control is the quiet hero of a quality agreement. Without it, a manufacturer can swap an excipient supplier, adjust a process, or substitute a raw material — and the first you hear of it is a customer complaint about a product that “feels different.” A change-control clause requires written notice and your approval before anything in your formula or process changes. It keeps your product your product.
If a manufacturer resists signing a quality agreement, treat that as the answer to whether they’ll stand behind your product when it matters.
It’s a written document defining the quality responsibilities of the brand owner and the contract manufacturer — specifications, testing, documentation, change control, and accountability for out-of-spec batches and recalls.
It isn’t strictly mandated, but the FDA expects brand owners to control quality. A quality agreement is the standard way to document that control and protect your brand if something goes wrong.
A supply agreement covers commercial terms like price and volume. A quality agreement covers quality responsibilities and accountability. You need both — the supply agreement alone won’t protect you in a quality failure.
