For Brokers Managing 10+ Importers

Your clients trust you to catch rate changes. Are you catching them?

One missed Section 301 change across 50 clients isn't one phone call. It's 50 phone calls, 50 amended entries, and one conversation with your E&O insurer. TariffDiff monitors every client's HTS codes and routes alerts to the right place before you're the last to know.

Annual exposure across a typical book

Fifty importers. Each one assumes you're monitoring their codes. You're managing this in spreadsheets and email forwards. One missed Section 301 change on a high-volume code and you're on the phone explaining why they owe $147K in retroactive duties. That call takes 4 minutes. The client relationship took 4 years to build.

How It Works for Brokers

Four steps. Complete coverage.

Set up once, monitor automatically. Every client gets their own alerting channel.

Step 01

Add your clients

Name each importer in your book. Add their webhook endpoint or email. Takes 30 seconds per client.

Step 02

Set their watchlists

Tell us which HTS codes matter for each client. Same code, different clients, different thresholds. All supported.

Step 03

Alerts route automatically

When HTS 8541.40 changes, Acme Importing's system gets Acme's alert. Your dashboard shows everything. No forwarding, no spreadsheets.

Step 04

Prove you were first

Every alert is timestamped and hash-addressed. When a client asks "when did you know?", you have the receipt.

What You See

A real alert, in plain English

This is what lands when a rate changes for one of your clients.

The next rate change is already in a Federal Register draft somewhere. The question is whether you find out from us in 12 minutes or from your client in 12 days.
