Appearing before Bradford magistrates on 28 February, UFP (UK) pleaded guilty to nine charges under the Producer Responsibility Obligations (Packaging Waste) Regulations 1997.
The Bradford-based company, which specialises in computer accessories, was fined £18,000.
UFP (UK) was also ordered to pay £2,304 compensation and £1,220 costs to the Environment Agency.
Under the Regulations, companies with an annual turnover above £2 million that handle more than 50 tonnes of packaging a year must register with the Environment Agency and recycle a proportion of that packaging.
UFP failed to register between 2004 and 2006, saving an estimated £6,000 by not doing so. It did not register, although its directors had discussed the issue in 2004.
The company registered with a producer compliance scheme in 2007.
