The shortest version of the rule
The filler-is-manufacturer rule means that it is not the party that produces the packaging material who bears responsibility, but the party that fills the packaging with a product and subsequently places it on the market. Do you buy cardboard boxes from a supplier, print them with your logo, and fill them with products you sell? In such cases, it is typically not the supplier of the cardboard who is designated as the manufacturer of the packaging, but your own business.
The most common mistake is assuming precisely the opposite: businesses reason that they did not make the box, so they cannot be responsible either. This does not align with how the regulations view the chain. It is not about who produces the material, but about who puts the product in it and places the whole thing on the market.
Why this thinking error occurs so frequently
The confusion usually arises because businesses are accustomed to other product oversight, where the manufacturer of the physical product is central. Packaging works differently: the packaging and the product in it are assessed separately. A supplier who only delivers boxes, bags, or film without filling them is generally not the party designated as the manufacturer of that packaging once you fill and sell it yourself. If you expect your printer or cardboard supplier to have already arranged the registration, that is an assumption that does not automatically hold true.
A common example
An online shop has neutral boxes printed with its own logo at a printing company. The online shop thinks: the printing company makes the packaging, so they will arrange the EPR registration. In practice, however, it is the online shop that fills the boxes with orders and ships them to customers. With this, the role of manufacturer typically falls to the online shop, not to the printing company that only supplies material.
What typically does and does not fall under the rule
Whether you are designated as a manufacturer depends on what you specifically do with the packaging. If you only supply empty packaging material to another business that fills it itself, the role usually lies with that other party. If you fill products into packaging that you subsequently sell or ship, there is a greater chance you qualify as a manufacturer, even if you did not design or produce the packaging yourself. Intermediate arrangements, such as fulfilment partners who pack on your behalf, have their own points of attention and are explained elsewhere.
Because the outcome differs by situation, and there are also borderline cases on which the guidelines themselves allow room for interpretation, it is wise not to rely on an assumption from the chain but to examine your own situation.
How to assess this for your own situation
Whether you are a manufacturer depends on the type of packaging, the country where you supply, and the way you fill and sell that packaging. A good first step is to examine this separately for each packaging stream: primary packaging, shipping packaging, and any collective packaging can each yield a different outcome. You can see where you stand in five questions, without requiring an account.
If you wish to read the underlying definitions yourself, you can consult the knowledge base for the precise descriptions by packaging type. It also indicates in which cases the role does not fall to you, which is just as important as knowing when it does.
What happens if you assess the role incorrectly
If you mistakenly believe that a supplier already bears the responsibility, it could mean that a registration that should have been in your name has not been done anywhere. The reverse also happens: companies register themselves as a precaution while the responsibility actually lies with another link in the chain, and as a result they pay for duplicate work or unnecessary contributions. Both situations can be prevented by making the question concrete for your own packaging flow, instead of adopting a general assumption from a supplier or competitor.

In summary
The most common mistake with the filler-is-manufacturer rule is assuming that whoever produces the material is also the responsible party. In many cases, this is not the producer of the cardboard or film, but the company that fills the packaging and places it on the market. If you are unsure whether this applies to your situation, you can check it in a few minutes.
