Additional classification lines incur a per line fee due to the labour intensive nature of product evaluation and tariff classification, as customs brokers are legislatively obligated to individually assess each and every product in your consignment.
All customs brokerages charge similar fees.
Note: Customs legislation defines a “tariff classification” according to the products essential character, not the quantity.
For example, if your consignment contains: 3 x men’s analogue watches, 5 x ladies dresses and 2 x tennis racquets (all with different styles/colours/sizes); then you will have 3 tariff classifications, not 10.
