FAQ
Do I need a customs broker?+
Not legally required, but strongly recommended. A licensed customs broker handles documentation, tariff classification, duty calculation, and communication with CBP. For FBA shipments, a broker familiar with Amazon logistics is essential.
What is ISF (10+2)?+
Importer Security Filing requires importers (or their brokers) to submit 10 data elements about ocean cargo to CBP at least 24 hours before loading onto a vessel at the foreign port. Failure to file results in $5,000 penalties per violation.
How do I get a CBP bond?+
A customs bond guarantees payment of duties to CBP. Continuous bonds (recommended for regular importers) cover all transactions for one year. Single-entry bonds cover one shipment. Bonds are obtained through a licensed surety company, typically via your customs broker.
