Key differences

What actually sets them apart

History and audits

HTS Hero calculates duty for a past entry date using the HTS revision in force that day, and charts each change to a product's duty over time. Gateway's calculator estimates current-day entries only, so it can't check what you should have paid last quarter.

Independence

Gateway's calculator is run by a freight forwarder. HTS Hero is a standalone tariff tool, so you can use it with any forwarder or broker.
