The majority of shipments seized had papers which underdeclared the weight of the shipments. a tactic which permits importers to evade quota limits based on weight equivalents. Agents also made many seizures of textiles manufactured in the Peoples Republic of China. These textiles were imported using fraudulent visas which allowed shipments to this country far in excess of the amounts permitted by quota. The other scam which resulted in significant seizures involved the violation of trademark and copyright laws. Much of the increase in seizures can be attributed to increased diligence on the part of the Customs Service. in part enhanced by the increased use of more sophisticated equipment such as portable scales.
