Firework Categories & P1 Guide – F1, F2, F3 & P1 Explained
Fireworks and other pyrotechnic articles sold on the European market can carry category markings such as F1, F2, F3, F4, P1, P2, T1 and T2. These codes are not simply a scale showing which product is more powerful.
Pyrotechnic categories describe the type and intended use of an article as well as its level of hazard, including relevant noise characteristics.
In this PiroHiT guide, we explain what F1, F2 and F3 fireworks mean, what category P1 represents, the difference between F2 and F3, and why P1 is not simply the next level after F3.

What are the main pyrotechnic categories?
Under the European classification system, pyrotechnic articles are divided into several main groups.
F – Fireworks:
- F1,
- F2,
- F3,
- F4.
T – Theatrical pyrotechnic articles:
- T1,
- T2.
P – Other pyrotechnic articles:
- P1,
- P2.
The classifications most frequently encountered when comparing consumer fireworks and other pyrotechnic products are F1, F2, F3 and P1.
What are F1 fireworks?
Category F1 covers fireworks presenting a very low hazard and a negligible noise level.
Under the European classification, F1 products are intended for use in confined areas, and the category can include certain products intended for use inside domestic buildings.
Depending on certification, F1 may include some:
- sparklers,
- small fountains,
- small visual effects,
- party pyrotechnics.
A small product is not automatically F1. The official category should always be checked on the original product label.
What are F2 fireworks?
F2 fireworks are one of the most common categories of consumer fireworks.
They are classified as fireworks presenting a low hazard and low noise level and are intended for outdoor use in confined areas.
Depending on the individual product, category F2 can include certain:
- firework cakes and batteries,
- rockets,
- fountains and volcanoes,
- Roman candles,
- single shots,
- other consumer fireworks.
The F2 marking alone does not tell you the exact calibre, number of shots or NEC of a product.
What are F3 fireworks?
F3 fireworks are fireworks presenting a medium level of hazard and intended for outdoor use in large open areas.
F3 products can require different safety distances and operating conditions compared with typical F2 fireworks.
Depending on the individual certification, F3 may include certain:
- larger firework batteries,
- cakes using larger calibres,
- single shots,
- larger fountains,
- other aerial or ground effects.
Examples of products classified in this group can also be found in our F3 Fireworks section.
F2 vs F3 fireworks – what is the difference?
The difference between F2 and F3 fireworks is not simply that F3 is “more powerful”.
| Feature | F2 | F3 |
|---|---|---|
| Hazard level | Low | Medium |
| Intended environment | Outdoor use in confined areas | Outdoor use in large open areas |
| Safety distance | According to the individual product | According to the individual product, often greater |
| Calibre | Depends on the product | Depends on the product |
| NEC | Depends on the product | Depends on the product |
You therefore cannot reliably identify an F2 or F3 article simply by looking at the size of the box, number of shots or calibre.
What does Category 3 fireworks mean?
The term Category 3 fireworks is commonly used to refer to F3 fireworks.
When looking at modern CE-marked fireworks, the official designation is F3.
Searches and descriptions may still use terms such as:
- Category 3 fireworks,
- Cat 3 fireworks,
- F3 fireworks,
- Category F3.
For technical identification, always use the classification printed on the actual product.
Does F3 always mean a larger calibre?
No. Calibre and category describe different properties.
Calibre usually refers to the diameter of a component such as a launch tube, while F2 or F3 is the classification of the complete pyrotechnic article.
The following assumption is therefore incorrect:
larger calibre = higher firework category.
Both parameters should be checked separately.
Are F3 fireworks professional fireworks?
No.
F3 is a separate category of fireworks presenting a medium hazard and intended for large open areas.
F4 is the category intended only for persons with specialist knowledge and is commonly referred to as professional fireworks.
What is P1 pyrotechnics?
P1 is one of the most commonly misunderstood pyrotechnic categories.
P1 is not a more powerful category after F3.
P1 covers pyrotechnic articles other than fireworks and theatrical pyrotechnic articles which present a low hazard.
This means that two P1 products can have completely different designs, purposes and effects.
You can read more in our dedicated P1 Pyrotechnics Guide – meaning, categories and differences.
P1 vs F2 – what is the difference?
F2 and P1 belong to different groups of pyrotechnic articles.
| Feature | F2 | P1 |
|---|---|---|
| Main group | Fireworks | Other pyrotechnic articles |
| Purpose | Entertainment / firework effect | Depends on the specific product |
| Hazard level | Low | Low |
| Typical products | Cakes, rockets, fountains and other fireworks | Various pyrotechnic products depending on intended purpose |
Is P1 stronger than F3?
This is not a valid comparison.
F1, F2, F3 and F4 all belong to the fireworks classification.
P1 belongs to the separate group of other pyrotechnic articles.
Therefore, the following scale is incorrect:
F1 → F2 → F3 → P1
P1 is not “level four”, nor does the P1 marking itself mean that a product is more powerful than an F2 or F3 article.
What are F4 fireworks?
F4 fireworks present a high hazard and are intended for use only by persons with specialist knowledge.
They are commonly described as professional fireworks.
F4 should therefore not be confused with F3 simply because both categories may include large pyrotechnic articles.
What are T1 and T2 pyrotechnics?
The letter T refers to theatrical pyrotechnic articles.
- T1 – pyrotechnic articles for stage use presenting a low hazard,
- T2 – theatrical pyrotechnic articles intended only for persons with specialist knowledge.
This group is separate from standard F1-F4 fireworks.
What is category P2?
P2, like P1, belongs to the group of other pyrotechnic articles.
However, P2 articles are intended for handling or use only by persons with specialist knowledge.
Does the category tell you how loud a firework is?
Not precisely.
Noise level is relevant to the classification of fireworks, but an F2, F3 or P1 marking does not provide a specific sound level in decibels.
Two products in the same category may produce very different sound effects.
If sound is an important characteristic, the individual product specifications and manufacturer information should be checked.
Does the category determine NEC?
No.
NEC – Net Explosive Content refers to the net quantity of pyrotechnic composition contained in an article.
NEC and pyrotechnic category are different technical specifications.
Two products belonging to the same category can have very different NEC values.
Does higher NEC mean a higher category?
No. An article is not classified only according to the amount of pyrotechnic composition it contains.
Classification can take into account factors including:
- product type,
- intended use,
- construction,
- level of hazard,
- noise level,
- safety distances.
NEC alone therefore does not determine whether a product is F2, F3 or another category.
What does CE mean on fireworks?
Pyrotechnic products placed on the European market under the applicable conformity system carry identifying and classification information, including a CE marking.
When checking a product label, look for information such as:
- category – for example F1, F2, F3 or P1,
- CE marking,
- registration information,
- NEC,
- instructions for use,
- safety distance where applicable,
- manufacturer or importer details.
The commercial product name alone should never be used to determine its official category.
How can you check a firework category?
The most reliable source is the original label of the specific pyrotechnic article.
The classification should be clearly stated, for example:
- F1,
- F2,
- F3,
- P1,
- T1.
Two products that look almost identical can still have different classifications.
F1, F2, F3 and P1 – quick comparison
| Category | Group | General classification |
|---|---|---|
| F1 | Fireworks | Very low hazard and negligible noise level |
| F2 | Fireworks | Low hazard and low noise level |
| F3 | Fireworks | Medium hazard, intended for large open areas |
| F4 | Fireworks | High hazard, for persons with specialist knowledge |
| P1 | Other pyrotechnic articles | Low hazard |
| P2 | Other pyrotechnic articles | For persons with specialist knowledge |
| T1 | Theatrical pyrotechnics | Low hazard |
| T2 | Theatrical pyrotechnics | For persons with specialist knowledge |
Frequently asked questions about firework categories
What are F1 fireworks?
F1 fireworks present a very low hazard and a negligible noise level and are intended for use in confined areas.
What are F2 fireworks?
F2 fireworks present a low hazard and low noise level and are intended for outdoor use in confined areas.
What are F3 fireworks?
F3 fireworks present a medium hazard and are intended for outdoor use in large open areas.
What does Category 3 fireworks mean?
Category 3 fireworks generally refers to F3 fireworks. F3 is the official category marking used on appropriately classified products.
What is the difference between F2 and F3 fireworks?
F3 has a higher hazard classification than F2 and is intended for larger open areas. The individual product's safety information must still be checked.
Are F3 fireworks professional fireworks?
No. F4 is the category intended only for persons with specialist knowledge. F3 is a separate category.
What does P1 mean in pyrotechnics?
P1 covers other pyrotechnic articles, excluding fireworks and theatrical pyrotechnics, which present a low hazard.
Is P1 stronger than F3?
No such conclusion can be drawn from the category. P1 and F3 belong to different classification groups.
Does calibre determine the firework category?
No. Calibre and category describe different characteristics of a pyrotechnic article.
Does NEC determine the category?
No. NEC is an important technical specification, but it does not independently determine whether an article belongs to F1, F2, F3 or another category.
Where can I find the category of a firework?
The official category should be shown on the original label of the specific pyrotechnic article.
Firework categories – the key point
The markings F1, F2, F3 and P1 should be understood as official classifications rather than a simple scale from “weak” to “powerful”.
When comparing pyrotechnic products, consider the category, NEC, calibre, construction, effect, safety distance and manufacturer's instructions together.
