Makita International (Europe), based in Milton Keynes, had complied with the regulations from 1997 to 2003, but in 2004 and 2005 it only registered with the Environment Agency and did not provide evidence of compliance.
During that time it produced more than 1,800 tonnes of packaging, which would have cost £7,800 to recover or recycle.
The company, which has a turnover of about £60 million, said staff changes led to the error.
It pleaded guilty before Milton Keynes magistrates on 27 October to two charges under the Producer Responsibility Obligations (Packaging Waste) Regulations 1997 and two under the amended 2005 regulations.
Kitchenware company Bodum was also fined under the regulations. Appearing before Northampton magistrates, Bodum (UK) of Swan Valley, was fined £12,000 with £1,125 costs after pleading guilty to six charges.
An Environment Agency investigation earlier this year found it had not registered with a compliance scheme in 2004 or 2005, despite handling more than 200 tonnes of packaging per year.
It saved £1,997 during those two years by not complying, although the Agency estimates it also saved £11,641 between 1999 and 2005.
Bodum said it had not been aware of the regulations.
