5 Critical Questions to Ask Before Choosing a Contract Manufacturer

I’ve spent over four decades formulating products for some of the industry’s biggest names. In that time, I’ve watched countless brands succeed—and watched others fail before they ever really started.

The difference almost always came down to one decision: choosing the right manufacturing partner.

When you’re evaluating contract manufacturers, every presentation looks polished. Every salesperson sounds confident. But behind the glossy brochures and flashy websites, you will find vast differences in capability, quality, and commitment.

Here are the five critical questions I recommend every brand owner ask before signing a contract. The answers will tell you everything you need to know.

Question 1: What Are Your Third-Party Certifications—and Can I See Them?

This is where the conversation should start. Anyone can claim to follow Good Manufacturing Practices. Proof is another matter.

What to Look For:

CertificationWhy It Matters
NSF InternationalRigorous third-party audit of facilities and processes
ULVerifies compliance with safety and quality standards
Organic CertificationsEssential if you’re formulating with organic ingredients
Gluten-FreeValidates testing protocols and cross-contamination controls
Kosher/HalalOpens doors to specific markets and consumer communities

The Follow-Up Question

“May I see your most recent audit reports?”

A transparent manufacturer shares them willingly. One who hesitates? That’s your answer.

At All American Pharmaceutical, we’ve earned 20+ third-party certifications because we believe your brand deserves protection at every step—from raw materials to finished goods.

Question 2: What Does Your Testing Protocol Actually Cover?

Testing isn’t a single event. It’s a process that should span the entire manufacturing lifecycle. If a manufacturer can’t articulate its protocol clearly, it probably doesn’t have one.

The Three Stages of Proper Testing

StageWhat Should Be Tested
Raw MaterialsIdentity, purity, potency, contaminants (heavy metals, microbes)
In-ProcessBlend uniformity, capsule weight, moisture content, and stability
Finished ProductLabel claims, dissolution, microbial limits, packaging integrity

The Follow-Up Question

“Do you test every batch—or just spot-check?”

Batch-by-batch testing is the only way to guarantee consistency. Spot-checking leaves room for precisely the kind of errors that destroy brands.

At All American Pharmaceutical, our triple-tested guarantee means every ingredient and every batch is tested three times. Your label claims are always rock-solid.

Question 3: Do You Have an Onsite Lab—or Do You Outsource Testing?

This question separates serious manufacturers from brokers who simply repackage others’ work.

Onsite Lab vs. Outsourced Testing

FactorOnsite LabOutsourced Testing
SpeedImmediate results, real-time adjustmentsDays or weeks waiting for third-party data
ControlFull oversight of methods and standardsReliance on someone else’s schedule and priorities
ExpertiseScientists who know your product intimatelyGeneralists running routine panels
CostInvested in quality, not markupsAdded layers of expense and delay

The Follow-Up Question

“May I see your lab?”

A manufacturer proud of their capabilities will welcome the tour. If the lab is “offsite” or “we use a partner,” ask exactly who does the testing and how you can verify their credentials.

At All American Pharmaceutical, our multimillion-dollar analytical lab houses advanced instrumentation—UHPLC, LC-MS, ICP-OES, and more—staffed by scientists who treat every product with the same rigor we apply to our proprietary ingredients.

Question 4: What’s Your Experience with My Type of Formulation?

Tablets, powders, liquids, creams—each requires different expertise, equipment, and problem-solving.

What to Ask About Your Specific Product

Product TypeKey Questions
TabletsDo you handle sustained-release? Enteric coatings? High-dose actives?
PowdersHow do you ensure particle size consistency? Mix uniformity?
LiquidsWhat’s your stability testing process? How do you prevent separation?
Creams/TopicalsDo you have experience with emulsifications? Preservative systems?

The Follow-Up Question

“Can you share an example of a similar formulation challenge you’ve solved?”

Listen for specifics. A great manufacturer doesn’t just say “yes, we can do that.” They explain how they’ve overcome similar obstacles—often with insights you hadn’t considered.

At All American Pharmaceutical, we’ve formulated everything from advanced sports nutrition complexes to delicate topical applications. Our team, led by scientists with decades of experience, applies deep expertise directly to overcoming your toughest formulation hurdles.

Question 5: Who Will Actually Formulate My Product—and What Are Their Credentials?

This might be the most important question of all. Many manufacturers separate sales from science. You meet with polished account managers, but the actual formulation work is handed to junior technicians following standard operating procedures.

What to Look For

CredentialWhy It Matters
Advanced DegreesPhDs and master’s-level scientists bring deep problem-solving ability
Industry ExperienceYears of formulating means fewer surprises
Patent HoldersScientists who’ve innovated understand how to protect your intellectual property
Published ResearchDemonstrates commitment to science, not just production

The Follow-Up Question

“Can I speak directly with the formulator who would handle my project?”

A manufacturer confident in their team says yes immediately. If there’s resistance, you’re being shielded from the very person who should be your closest ally.

At All American Pharmaceutical, our team applies deep expertise directly to your toughest challenges. With 40 US and international patents, we don’t just follow formulas. We create them.

The One Question That Ties Them All Together

After you’ve asked these five, there’s one final question that reveals everything:

“May I visit your facility?”

Nothing replaces walking the floor. Seeing the equipment. Meeting the scientists. Observing the cleanliness, the organization, and the culture.

A manufacturer confident in their quality welcomes visitors. We do.

Making the Right Choice for Your Brand

Choosing a contract manufacturer is one of the most consequential decisions you’ll make. The right partner accelerates your growth, protects your reputation, and sleeps as soundly as you do, knowing your products are right.

The wrong partner? They’ll cost you far more than you “saved.”

At All American Pharmaceutical, we invite your hardest questions. Our certifications are current. Our labs are open. Our scientists are accessible. And our triple-tested guarantee ensures your brand is protected at every step.
