Supplements on Amazon US: compliance without losing sales

By the Finnex Agency team

A supplement can sell well for months, hold good reviews, and generate sales every single day.

And even so, a compliance request can appear that requires you to submit documentation, complete a verification, or go through a testing process before you can keep selling normally.

For a brand that depends on few ASINs, this can turn into a revenue problem very quickly.

The important point is that compliance doesn't begin when Amazon's notification arrives.

It begins much earlier: with the manufacturer, the documentation, the product, the labeling, and the information you use in the listing.

Since April 2024, Amazon has required verification through external Testing, Inspection and Certification (TIC) organizations for dietary supplements. When a product requires action, Amazon surfaces it inside its compliance tools and sets out the corresponding steps and deadlines.

In this article we'll walk through how this process currently works for supplements sold on Amazon United States, what role TIC providers play, what's worth reviewing when a request appears, and how to prepare your catalog so you can act before a compliance problem ends up affecting your sales.

The goal isn't to turn you into a regulatory specialist.

It's for you to know what to review, what to ask, and where a problem can show up.

1. What matters before we start

When we talk about compliance on Amazon, it's easy to think only about documents.

But the problem can be considerably broader.

A request can involve the product, the manufacturer, the labeling, the results of a test, or the information attached to the listing.

That's why a supplement can be performing perfectly from a commercial standpoint and, at the same time, have a problem from a compliance standpoint.

This matters especially for small and mid-sized brands.

If a brand does US$30,000 a month across three products and one of them accounts for half of sales, an interruption on that ASIN isn't simply an operational problem.

It's a business problem.

So the objective shouldn't be to react quickly when an alert appears.

It should be to arrive at that moment with the information already organized.

What does being prepared mean?

At a minimum, you should be able to answer quickly:

• Who manufactures each product?
• Where is it manufactured?
• What documentation exists?
• What certifications does the manufacturer hold?
• What information appears on the label?
• What claims does the listing use?
• Which ASINs and variations are involved?
• Which documentation corresponds to each product?
• What deadline did Amazon give?

If those answers take several days of digging, there's probably a management problem before there's even a compliance problem.

2. What changed and why it matters

On April 2, 2024, Amazon announced changes to its dietary supplements policy and established that products subject to these requirements must be verified through an external Testing, Inspection and Certification organization, known as a TIC.

This matters because it changes how many sellers were used to handling documentation.

It isn't simply a matter of keeping a PDF in Google Drive and uploading it when Amazon asks.

Amazon uses a specific verification process and, where applicable, the seller has to work with one of the approved TIC providers.

What does TIC mean?

TIC stands for:

Testing, Inspection and Certification.

These are external organizations that carry out testing, inspection, or certification processes to verify particular product requirements.

When Amazon requests this process, the seller starts the request from the compliance tools and continues it with the corresponding provider.

The verification result has to reach Amazon through the process the provider establishes.

That's why having your own documentation from the manufacturer can be very useful, but it doesn't automatically mean that document replaces a TIC verification requested by Amazon.

---

3. So where does cGMP come in?

Here's one of the most common points of confusion.

cGMP stands for Current Good Manufacturing Practices.

In the United States, the FDA sets specific good manufacturing practice requirements for dietary supplements under 21 CFR Part 111.

These requirements relate to how supplements are manufactured, packaged, labeled, and held, and they aim to ensure aspects such as the identity, purity, quality, strength, and composition of the product.

But two concepts have to be kept apart:

cGMP is not the same as Amazon's TIC process.

cGMP is part of the regulatory framework applying to the manufacture of dietary supplements.

TIC is the testing, inspection and certification process Amazon uses to verify compliance for particular products.

So a line like:

"I have a cGMP certificate, so Amazon can't ask me for a verification"

is too simplistic.

If Amazon generates a specific request for an ASIN, you follow the process indicated in Seller Central.

---

4. Who does what: manufacturer, TIC, and seller

A good way to understand the process is to separate responsibilities.

The manufacturer

The manufacturer should be able to provide information and documentation related to the product and how it's made.

Depending on the case, this can include:

• facility information;
• manufacturing documentation;
• product specifications;
• ingredient information;
• quality documentation;
• available certificates;
• analytical results;
• batch-related information.

Not every product will require exactly the same documents.

That's why it's important not to work from a generic checklist as if all supplements were the same.

The TIC provider

This is the approved external organization that carries out the testing, inspection, or certification process Amazon requested.

The provider may require information, samples, and documentation before completing the evaluation.

The seller

The seller is responsible for coordinating the process.

That means:

1. identifying the affected product;
2. reviewing the request;
3. contacting the manufacturer;
4. providing the necessary information;
5. starting the TIC process where applicable;
6. tracking deadlines;
7. keeping the documentation and the results.

And here's a very important practical rule:

a seller shouldn't be discovering how their product is manufactured while Amazon is already asking them to verify it.

Ideally, that information should have been organized long before.

---

5. The day Amazon's notification arrives

This is probably the moment when mistakes are easiest to make.

When a compliance request appears, the natural reaction can be:

"Which document do I upload?"

But the first step should be a different one.

First you have to understand exactly what Amazon is asking for and for which product.

Amazon uses its compliance tools to surface the products that require action and the corresponding steps.

What to do first

1. Identify the affected product.

Don't assume your whole catalog is involved.

2. Read the full request.

Don't stop at the notification's headline.

3. Check the deadline.

Not every case runs on the same timeline. The date shown in the request is the one that should drive the action.

4. Review the ASIN and its variations.

Confirm exactly which product is involved.

5. Check who manufactures it.

You need to know what information to request and from whom.

6. Start the process Amazon indicates.

If the request calls for testing or verification through a TIC provider, follow the process indicated in Seller Central.

7. Keep everything.

The request, the case number, documentation, samples, results, emails, and communications.

Why waiting isn't a good idea

Because these processes can require coordination with third parties.

Amazon notes that testing can take time once the provider receives the samples.

Waiting until the last moment can leave you without room to correct a problem, repeat a test, or obtain additional documentation.

The practical rule is straightforward:

if a request arrives, start as soon as possible.

---

6. The variation trap

Variations can make a compliance problem more complex than it looks.

Picture a brand selling:

• 60 capsules;
• 120 capsules;
• lemon flavor;
• orange flavor.

All of them can belong to the same variation structure.

But that doesn't mean you should automatically assume one verification covers any other presentation.

The right question is:

Which products and ASINs are included, exactly, in this request?

It isn't safe to assume that a certification, test, or document applied to one product automatically covers every variation.

What should you review?

For each variation, it's worth having identified:

If there's any doubt, the right move is to confirm it with the TIC provider and review the specific scope of the request.

---

7. The listing is part of the problem too

Compliance doesn't end at the lab.

A brand can have a correctly manufactured product and still create problems through the way it presents it.

This matters especially in supplements, because there are requirements around how certain claims can be presented.

The FDA regulates dietary supplements under a different framework than the one used for drugs, and there are important limits on the statements that can be made about these products.

So before publishing or updating a listing, it's worth reviewing four layers:

1. Product

What does it actually contain?

2. Label

What ingredients, amounts, instructions, and warnings appear?

3. Listing

What is the brand claiming about the product?

4. Keywords

What terms are we using to attract traffic?

The problem shows up when these four layers start telling different stories.

A simple example

Suppose a brand sells a sleep-oriented supplement.

It isn't the same to communicate:

"Supports healthy sleep patterns."

as to state:

"Treats insomnia."

The second statement presents the product as a treatment for a medical condition and can move it onto entirely different regulatory ground.

That's why SEO shouldn't be analyzed through search volume alone.

You also have to ask:

Does this term correctly describe the product and the claim we're able to make?

A keyword with high volume can be a bad keyword if it implies a statement the product can't support.

---

8. Not all documents serve the same purpose

Another frequent source of confusion is mixing documentation together.

A brand might hold:

• a GMP certificate;
• a Certificate of Analysis;
• lab results;
• manufacturer documentation;
• product specifications;
• batch records;
• ingredient documentation;
• third-party certificates.

All of them can be useful.

But they don't necessarily serve the same function.

A Certificate of Analysis (CoA), for instance, can provide information about one specific batch.

A certificate relating to good manufacturing practices speaks to something else.

And a TIC verification requested by Amazon is a different process again.

So it isn't wise to build a compliance strategy around the question:

"What PDFs do we have?"

The right question is:

"What is Amazon asking for, and what evidence demonstrates exactly that requirement?"

---

9. What happens to advertising while the issue is open?

Here you have to separate Amazon policy from business management.

Amazon determines what happens to a product when there's a specific non-compliance or restriction.

But the decision to keep increasing ad spend is a management decision.

So if a compliance problem appears, before aggressively raising budget it's worth reviewing:

• the ASIN's current status;
• the deadline;
• the likelihood of interruption;
• the share of sales it represents;
• available inventory;
• how much the catalog depends on that product.

This doesn't mean automatically switching off every campaign.

It means avoiding investment decisions taken without knowing the operational risk.

For example:

If an ASIN accounts for 60% of sales and there's an open compliance request, raising ad budget by 50% without reviewing the situation first may not be the best decision.

The problem isn't only CPC.

It's the possibility of investing to generate a sale you then can't fulfill normally.

---

10. Inventory should be part of the conversation too

The same principle applies to stock.

Picture a brand with:

US$80,000 of inventory in transit.

At the same time, one of its main ASINs is going through a compliance process.

That doesn't necessarily mean the order should be cancelled.

But it does mean the risk should be part of the decision.

Before committing large amounts of capital to inventory, it's worth knowing:

• which ASIN concentrates sales;
• which products have open requests;
• which manufacturer is involved;
• what documentation exists;
• how long resolving a problem could take;
• what alternatives the brand has.

Compliance isn't only a regulatory matter.

It can become a variable of cash flow, inventory, and profitability.

11. How to get ahead of it: build a compliance file per ASIN

The best strategy isn't a folder called "Compliance" full of PDFs.

It's knowing exactly which document corresponds to which product.

A simple structure can be enough.

For each ASIN, record:

Product

• ASIN
• SKU
• commercial name
• presentation
• manufacturer

Manufacturing

• manufacturer name
• location
• available documentation
• relevant certifications
• issue or expiry dates where applicable

Product

• formula
• ingredients
• specifications
• available analytical documentation
• current label

Amazon

• compliance status
• open requests
• deadline
• TIC provider
• request number
• result

Listing

• title
• bullets
• description
• A+ Content
• images
• claims
• relevant keywords

---

12. Think about the manufacturer too

There's a point many brands discover too late.

Compliance risk doesn't depend on the ASIN alone.

There can also be risk concentration at the manufacturer.

Picture this:

• 5 ASINs;
• 3 manufacturers;
• 4 ASINs depend on the same manufacturer.

If a problem appears involving that manufacturer, the potential impact can be far larger than that of a single ASIN.

So beyond measuring:

sales by ASIN

it's worth knowing:

sales by manufacturer.

That's what shows you where the risk is actually concentrated.

---

13. Compliance and profitability are more connected than they look

Suppose a brand has:

• US$50,000 in monthly revenue;
• 5 ASINs;
• 1 ASIN accounting for 45% of sales;
• that product carrying an open compliance request.

The problem is no longer only:

"How do we resolve the request?"

You also have to ask:

"What impact would an interruption have on our business?"

That's where other metrics come in:

• revenue by ASIN;
• TACoS;
• margin;
• inventory;
• manufacturer dependency;
• the product's share of sales;
• organic sales vs. PPC.

That's why compliance should be part of the account's strategic conversation.

Not only the legal or documentary one.

14. What you shouldn't mistake for a compliance problem

Not everything affecting a listing is compliance.

And telling them apart correctly saves an enormous amount of time.

Compliance

Can involve safety requirements, documentation, testing, certification, or regulatory information.

Suppression

Can relate to content, category, image, attribute, or other catalog requirements.

A variation problem

Can involve incorrect parent-child relationships, attributes, or differences between products.

A commercial problem

Can simply be:

• a drop in conversion;
• rising CPC;
• lost ranking;
• competition;
• price;
• stock;
• reviews;
• changes in demand.

The mistake is treating all of these as if they were the same.

A good diagnosis starts by identifying:

what kind of problem is in front of us.

15. The checklist you should have before Amazon asks

If you sell supplements on Amazon United States, this can be a good baseline for reviewing your operation.

Product

☐ I know exactly who manufactures each product.

☐ I've identified the manufacturer's location.

☐ I have the available documentation organized.

☐ I've identified the relevant certifications.

Manufacturing and quality

☐ I know the compliance status of the facilities.

☐ I have access to the documentation a verification could require.

☐ I know what information to request from the manufacturer if Amazon generates a request.

Labeling and listing

☐ The label matches the current formulation.

☐ Ingredients and amounts are correctly documented.

☐ The images represent the actual product.

☐ The listing's claims have been reviewed.

☐ The keywords don't create claims the product can't support.

Amazon

☐ I know where to find Manage Your Compliance.

☐ I review open requests regularly.

☐ I keep track of deadlines.

☐ I know which ASINs are involved.

☐ I know the process for starting a TIC verification when Amazon requests one.

Management

☐ I have a compliance file per product.

☐ I know what share of my sales depends on each ASIN.

☐ I know what share of my sales depends on each manufacturer.

☐ I have a procedure for responding to a notification.

☐ The manufacturer and the Amazon team can coordinate quickly when needed.

16. The goal isn't to react faster

It's to react earlier.

The difference sounds small, but it completely changes how an account is managed.

A reactive brand waits for the notification.

A prepared brand already has:

• documentation organized;
• manufacturer information;
• labels up to date;
• ASINs identified;
• claims reviewed;
• variation structure under control;
• financial impact understood.

When the request arrives, it doesn't start an investigation from zero.

It starts a process.

And that difference can save time, money, and sales.

What a brand already operating this way looks like

It helps to look at a large brand that works this way.

Physician's Choice, one of the best-selling probiotic brands on Amazon in the United States, publishes a quality standards and testing page on its own site.

There it states that its facilities are cGMP compliant and independently audited, with certifications such as NSF cGMP and FSSC 22000.

It also indicates that it sends finished product to independent labs like Eurofins, and that part of its catalog carries the Non-GMO Project Verified seal.

What's interesting isn't the page itself.

It's the position it leaves them in.

The documentation exists, it was issued by recognized organizations, and it's identified product by product.

If a request appears tomorrow, that brand doesn't start by asking its manufacturer what certifications it holds.

It starts directly with the process.

And that's exactly the difference between a brand that reacts and a brand that was prepared.

You don't need to do millions in revenue to work this way.

You need the information organized before you need it.

Conclusion: protecting your ASINs starts long before the notification

On Amazon United States, selling supplements isn't only a matter of PPC, SEO, price, and conversion.

There's also a compliance layer that can directly affect product availability.

Amazon introduced verification requirements through TIC organizations for dietary supplements in 2024, and it uses its compliance tools to indicate when a product requires action.

At the same time, supplements are subject to the FDA's regulatory framework, including the Current Good Manufacturing Practices requirements set out in 21 CFR Part 111.

So compliance shouldn't be seen as a document you go looking for when Amazon asks for it.

It should be part of how the product is managed.

Because a well-managed ASIN isn't only an ASIN that sells.

It's an ASIN whose product, documentation, listing, and operation are ready to keep selling when Amazon asks questions.

The best compliance strategy doesn't start with a notification.

It starts with being ready for one.
