Common for this category of single ignition effect batteries is that they contain more than 1000 grams of gunpowder and can have a larger tube diameter than a normal battery. These articles can only be sold directly from importer and are not available at common firework vendors.

For the person with a genuine interest in fireworks that craves for larger articles than the normal consumer can buy this over the counter. DSB approves different compositions of class 4 batteries with an inner tube diameter up to 100 mm and up to 10 kilos. NO! Totally for the whole battery.

These articles are only permitted sold directly from the importer to the end consumer. Furthermore the customer must have:

1. Participated and passed the class IV security course at Svea Fyrverkerier AS.
2. Have permission from the landowner from whose address the firework is intended to be shot from.
3. Apply for permission for firing and get this approved from the local fire brigade, and
4. Inform the local police authorities that the launch is taking place before he or she can purchase the articles.
