- Quota entries are entries that are regulated by U.S. Customs to a specified quantity. There are two types of quota entries – Absolute and Tariff-rate quotas. Absolute quotas limit to a set quantity to be imported. Tariff-rate quotas allow for specified quantities to receive reduced duty rates and unlike Absolute quotas, even if the specified quantity limit is reached, shipments can still be imported at higher duty rates. Please contact our offices for specifics on whether your import shipment is subject to quotas.
