2002, especially concerning the safety of fireworks storage. Since then, the Vuurwerkbesluit has been amended a number of additional times, including the 2014 limitation of the period during which fireworks may be lit during New Year's Eve from 10 am to 6 pm on 31 December. Since the adoption of the 2007 European Pyrotechnic articles Directive, the Dutch Vuurwerkbesluit has been amended by 2010 to harmonise legislation with that of other EU member states concerning, amongst other things, the categorisation, trade and safety of fireworks, and a common approach of countering illegal fireworks. The updated 2013 Pyrotechnic articles Directive led to another amendment of the Vuurwerkbesluit. So-called "consumer fireworks" (consumentenvuurwerk or particulier vuurwerk) in the Netherlands consists of category F1 (on sale and usable throughout the year by every person aged 12 and older without a special licence or training), and category F2 and F3 (on sale the last three days of the year, Sundays excepted, which are to be lit from 6 pm on 31 December until 2 am on 1 January). Category F4 is reserved for professionals, and aside from New Year's Eve, categories F2 and F3 are also reserved for professionals.

Because of "flaws in the Pyrotechnic articles Directive", there are dangers for local security and terrorist threats. The Netherlands also have a considerable illegal fireworks problem. In 2014, about 1 million kilos of illegal fireworks entered the country annually. According to inquiries by VeiligheidNL, illegal fireworks used to cause most fireworks-related injuries (almost two-thirds of all fireworks-related injuries during New Year's Eve 2012–13), but since New Year's Eve of 2013–14 more than half was caused by legal fireworks. Illegal fireworks were responsible for more serious injuries, however, and resulted in four times as many hospitalisations. During New Year's Eve 2014–15, the percentage of injuries by illegal fireworks decreased to almost 40%. During New Year's Eve 2015–16 and 2016–17, illegal fireworks were to blame for about 25% of fireworks-related injuries. For New Year's Eve 2020-21, the government prohibited fireworks, citing that the number
