Does anyone know what the net explosive content limit is for cat 3 rockets? Am I right in thinking that for ground fireworks, i.e cakes, it is 2kg?

i believe the max wight of a rocket is 200 grams and yes the max weight of a cake is 2kg NEC with a max total weight of 10 kilos including tubes/glue/woodwork/etc

In the United Kingdom fireworks cannot be sold to people under the age of 18 and are not permitted to be set off between 11pm and 7am with exceptions only for New Year, Bonfire Night (5 November), the Chinese New Year and Diwali.[15] The legal NEC (Net Explosive Content) of a UK Firework available to the public is 2 Kilos- 4 times the legal amount in the USA. Jumping Jacks, Strings of Firecrackers, Shell Firing tubes, Bangers and Mini-Rockets were all banned during the 1990s. In 2004 single shot Air Bombs and Bottle Rockets were banned, and rocket sizes were limited. From March 2008 any firework with over 5% flashpowder per tube will be classified 1.3G. The aim of these measures was to eliminate "pocket money" fireworks, and to limit the disruptive effects of loud bangs.

acording to this....its 2kg!

For a very specific legal matter please take professional advice specifically from a fireworks law specialist. Please also note that they are massively busy til after the 5th nov now! Remember that forum members may or may not have the specific knowledge that you need.

illuminateconsult.co.uk will be such a company's www when live! They are fireworks advisors at the moment (very busy for the 5th!) When their site is live there will be online advice for related matters, but due to the nature of it much will be in the subscription part of the site.

You also have to be mindful that there is no direct correlation between the 1.3G/1.4G and Cat2/3/4 fireworks
