Is a User Manual Legally Required?
The Short Answer
The Duty Comes From the Product Rule
No single law says every product needs a user manual. The duty comes from the rule that governs your product type: machinery, consumer goods, connected products, batteries, construction products, and medical devices each have their own, with their own content, language, and delivery conditions. Contracts and customer specifications add more.

- Liability: Product Liability Directive (EU) 2024/2853

A product can fall under more than one of these at once. Where two apply, both sets of content belong in the manual.
United States
Fewer Statutes, More Contracts
- Radio-frequency devices: 47 CFR 15.105
- For Class A and Class B digital devices and peripherals, the instructions furnished to the user must include the FCC's interference statement, or a similar one, placed in a prominent location in the text of the manual.
- Building and facility turnover
- Operation and maintenance manuals are usually a contract requirement, not a statute. The specification or contract you are bound by sets the contents, format, and submittal dates. What goes into a building O&M manual.
- Medical devices
- US device labeling has its own directions-for-use rules, separate from the EU ones. FDA device labeling under 21 CFR 801.
The rows above are the ones covered on this site. Other federal and state rules apply to particular product classes, so a US product needs its own check beyond this list.

Practical Steps
- List the regimes your product falls under, by product type and by market. One product can sit under several, such as a connected machine with a portable battery.
- For each, read the article that sets the instructions duty, and note the language rule, the digital-delivery conditions, and the application date.
- Find each Member State's language determination for the markets you sell in. The EU texts leave the choice to the Member State.
- Merge the required content into one manual rather than keeping a manual per rule, and record which clause each section answers.
- Check contracts and customer specifications. They often ask for more than the law does.

FAQ
Questions We Hear
Is there one law that requires a manual for every product?
Not in the rules mapped here. Each one applies to a product class: machinery, consumer products, connected products, batteries, construction products, medical devices. A product outside all of them may still be covered by national rules or by a contract, so check both.
Can a consumer product skip the manual?
Under the General Product Safety Regulation, Article 9(7) does not apply where the product can be used safely and as intended by the manufacturer without instructions and safety information. That exception is narrow, and it sits beside warnings and other labeling duties in the same Regulation. Read the text for your product.
What language must the manual be in?
For machinery, consumer products, and construction products, the EU texts say a language users or consumers can easily understand, as determined by the Member State. They do not list languages. You need the national rule for each country where you sell.
Can the manual be digital only?
Sometimes. The EU rules differ on whether paper is owed on request, how long digital copies must stay online, and when each applies. Our comparison of EU rules on digital manuals sets them side by side.
What does the FCC require in a manual?
For Class A and Class B digital devices and peripherals, 47 CFR 15.105 requires the instructions to include the prescribed statement, or a similar one, in a prominent location in the text of the manual. Read the section for the exact wording of each class.
Does having a manual protect against a liability claim?
Not by itself. Under the Product Liability Directive, the instructions are one factor in whether a product is defective, alongside its presentation, foreseeable use, and the time it was placed on the market. Accurate, current instructions help; they do not settle the question.
