The filled container that has no label yet
A supplement can be finished, sealed and sitting on a shelf before anyone decides whose name goes on it. The rules address that gap directly, and the way they do it explains a lot about the market.
A finished batch can still be nameless
Manufacturing and labeling are separate operations, and they do not have to happen on the same day.
The rules contemplate that plainly. One of the required practices is "Identifying, by any effective means, filled dietary supplement containers that are set aside and held in unlabeled condition for future label operations, to prevent mixups."
Read slowly, that sentence describes a real inventory: sealed containers of finished product with nothing on them, waiting.
It is also the physical explanation for something visible in this market. A single filled batch can become several branded products, because the decision about the label comes later.
Keeping the labeling apart from everything else
Because unlabeled stock exists, the rules put distance between operations rather than trusting attention.
One required practice is "Establishing physical or spatial separation of packaging and label operations from operations on other components and dietary supplements to prevent mixups."
That is a layout requirement. It asks for the operations to be in different places, not merely done carefully.
The rest of the same section is ordinary and still worth knowing: cleaning and sanitizing filling and packaging equipment, protecting product from contamination, particularly airborne, and using sanitary handling procedures.
Where the number on the bottle is assigned
Numbering happens at this stage, and the section assigns two of them rather than one.
A batch, lot or control number goes on "Each lot of packaged and labeled dietary supplement from a finished batch of dietary supplement."
A separate one goes on "Each lot of dietary supplement, from a finished batch of dietary supplement, that you distribute to another person for packaging or labeling."
So material leaving to be labeled elsewhere is numbered before it goes. What that number is for, and how to use one, are covered in their own articles here.
The check on the packaged product
Finishing a batch is not the last test. The packaged and labeled product is examined in its own right.
The practice required is "Examining a representative sample of each batch of the packaged and labeled dietary supplement" against the specifications set for it.
That is a different question from whether the batch was good. It asks whether the thing in the container, as packaged and labeled, matches what was specified.
The company also has to be able to "determine the complete manufacturing history and control of the packaged and labeled dietary supplement through distribution."
Relabeling is a decision somebody signs
Repackaging and relabeling get their own short section, and every sentence in it is a gate.
The first: "You may repackage or relabel dietary supplements only after quality control personnel have approved such repackaging or relabeling."
The second requires an examination of a representative sample of each repackaged or relabeled batch, against the specifications for a packaged and labeled supplement.
The third closes it: quality control personnel approve or reject each such batch before its release for distribution. Changing a label is treated as a manufacturing act, not an administrative one.
Rejected after packaging
Product can fail at the very end, and the rule for that is one sentence.
A company must "clearly identify, hold, and control under a quarantine system for appropriate disposition any packaged and labeled dietary supplement that is rejected for distribution."
This is the same shape used for rejected incoming material. Rejection puts something into a controlled state, and a decision has to follow.
The point is that finished, labeled, saleable-looking product is inside the same system as raw material that failed on arrival.
Holding: temperature, humidity and light
The holding rules are brief, and their value is in naming what is being protected.
Components and supplements are held "under appropriate conditions of temperature, humidity, and light so that the identity, purity, strength, and composition of the components and dietary supplements are not affected."
Packaging and labels are held so that they are not adversely affected, and everything is held under conditions that do not lead to mixup, contamination or deterioration.
In-process material gets its own line. A company must "identify and hold in-process material under conditions that protect against mixup, contamination, and deterioration," under appropriate temperature, humidity and light.
The sample kept in the same packaging
Reserve samples are collected under a different section, covered elsewhere on this site. How they are held is here, and the detail is the useful part.
They are held under conditions "consistent with product labels or, if no storage conditions are recommended on the label, under ordinary storage conditions."
And the container matters as much as the contents. The sample is held "Using the same container-closure system in which the packaged and labeled dietary supplement is distributed."
The retention period is tied to the product. Samples are kept "for 1 year past the shelf life date (if shelf life dating is used)." Where it is not used, the period is "2 years from the date of distribution of the last batch of dietary supplements associated with the reserve samples."
Leaving the building
The distribution requirement is the shortest sentence in either subpart, and it is broader than it looks.
A company must "distribute dietary supplements under conditions that will protect the dietary supplements against contamination and deterioration."
There is no temperature named and no method prescribed. The standard is the outcome, which means it follows the product into transit rather than stopping at the loading dock.
The records requirement is equally short. Written procedures for holding and distributing operations, and "Records of product distribution."
What this changes about a bottle in front of you
None of these records is published, and nothing in either subpart requires any of it to reach a buyer.
What the sections do is describe the stage where one physical batch turns into branded products. Two bottles with different names on them can come from the same filling run, and the rules take that for granted.
They also set a standard the market often misses. A relabeled product is not a paperwork change; it needs an approval, an examination against specifications, and a release decision.
And the retention rule gives a quiet piece of good news. A sample of a distributed batch, in the same packaging, is supposed to still exist for a year past the shelf life date, for use in investigations.
Key takeaways
- The rules expressly contemplate filled, sealed supplement containers held unlabeled for later labeling.
- Those containers have to be identified, and packaging and label operations physically or spatially separated.
- A batch or lot number is assigned both to packaged product and to product shipped elsewhere to be labeled.
- A representative sample of each packaged and labeled batch is examined against its own specifications.
- Repackaging or relabeling requires prior approval, an examination, and a release decision by quality control personnel.
- Finished product rejected for distribution goes into quarantine for a documented disposition.
- Holding conditions are stated in terms of temperature, humidity and light, and what they must not affect.
- Reserve samples are held in the same container-closure system and kept a year past shelf life, or two years past distribution.
Frequently asked questions
Can a supplement be filled before anyone decides what to call it?
The rules assume so. One of the required packaging practices is identifying, by any effective means, filled containers that are set aside and held in unlabeled condition for future label operations, to prevent mixups. That is a description of finished, sealed product waiting for a label. It is also why a single filling run can become more than one branded product.
What stops the wrong label going on?
Separation and examination, rather than care alone. Packaging and label operations have to be physically or spatially separated from operations on other components and supplements, to prevent mixups. Unlabeled filled containers set aside for later labeling have to be identified. Before packaging and labeling, packaging and labels for each batch are examined against the master manufacturing record. Afterward, a representative sample of each packaged and labeled batch is examined against its specifications.
Is relabeling a product a big deal?
Under these rules it is a manufacturing act. A supplement may be repackaged or relabeled only after quality control personnel have approved that repackaging or relabeling. A representative sample of each repackaged or relabeled batch is then examined against the specifications for a packaged and labeled supplement. Quality control personnel approve or reject each batch before it is released for distribution.
What happens to finished product that gets rejected?
It is clearly identified, held and controlled under a quarantine system for appropriate disposition, the same treatment given to rejected incoming material. Being finished, labeled and saleable in appearance does not take it out of that system, and a disposition decision still has to be made and recorded.
How is a supplement supposed to be stored before it ships?
Components and supplements are held under appropriate conditions of temperature, humidity and light, so that identity, purity, strength and composition are not affected. Packaging and labels are held so they are not adversely affected. Everything is held under conditions that do not lead to mixup, contamination or deterioration. In-process material is identified and held under the same kind of protection.
Does a sample of my batch still exist?
For a while, in principle. Reserve samples are held in the same container-closure system the product is distributed in, under conditions consistent with the product label or, if none is recommended, ordinary storage conditions. They are retained for one year past the shelf life date where shelf life dating is used, or for two years from the date the last associated batch was distributed, for use in appropriate investigations. Nothing entitles a buyer to one, and the collection requirement itself sits in a different section covered elsewhere here.
