The Revenue's customs service has warned that the number of counterfeit products being brought into Ireland from abroad through the post is on the increase.

The level of fakes is increasing despite a record detection level last year.

Revenue officials said today that counterfeit products coming to Ireland from China now account for 90% of all counterfeit goods sold here.

There were were seizures of almost 400 counterfeit goods through the post, airports and ports in 2007. The value of the goods was estimated at more than €1.6m, up €500,000 on all previous yearly records.

This week, customs staff also detected a major drugs haul going through the post at the national mail centre in the midlands.
