Read guide →Start with the guides when you need a decision path: whether a customs bond is required, who pays tariffs, how customs clearance works, which CBP form controls a filing step, or how duty drawback can recover paid duties. Each guide is written for import teams that need to brief finance, operations, and suppliers before a shipment is filed.
Use the customs glossary when a term appears on a broker invoice, arrival notice, CBP request, or ACE report and you need a quick definition. Use the tools when you need to screen a number: HTS candidates, duty exposure, or customs bond size.
If a topic affects a live entry, do not rely on a guide alone. Pair the resource with commercial invoices, packing lists, HTS support, country-of-origin evidence, and broker review before filing.
