Customs workflow
Customs workflow software for US and Mexico imports
Tyllus runs the customs side of every ocean import for importers and their import teams: it sends your customs broker the request 7 days before ETA, records ISF filing and clearance status, shows holds with their reason, and reads each 7501 or pedimento into duty, fee and tariff code analysis. US and Mexico imports run in one place.

What does Tyllus do for customs?
Tyllus coordinates customs from shipping documents to release for US ocean imports and definitive ocean imports into Mexico. Tyllus works with your licensed customs broker rather than replacing it: the broker files the entry, and Tyllus makes sure the request, the documents and the reminders reach the broker on time and brings the result back into the shipment.
- Automatic customs request to your broker 7 days before ETA, re-timed whenever the ETA changes.
- ISF filed confirmation from the broker for US imports, or the reason it is not filed yet.
- Clearance status from the broker: cleared, in progress, on hold with a reason, not started or not cleared.
- For Mexico, confirmation that the pedimento is validated and paid and that the goods were actually released.
- Customs readiness per container: which documents are complete and which are missing, with upload, send and request actions.
- Duty and fees read line by line from every 7501 and pedimento.
How does the customs broker handoff work in Tyllus?
Customs steps run on dates set from the ETA, not on someone's memory. The broker acts through a secure link tied to one shipment and one request, without creating an account.
The broker's link shows the house bill of lading, commercial invoice and packing list, so the broker answers from the same documents your team sees. If the broker stays silent, Tyllus sends reminder rounds and then warns you.
Read the broker handoff timeline as text
Step 1: after stuffing, the forwarder uploads the house bill of lading and ISF, and Tyllus reads them. Step 2: Tyllus asks the broker to confirm the ISF is filed. Step 3: 7 days before ETA, Tyllus sends the broker the customs request. Step 4: 5 days before ETA, Tyllus checks the house bill of lading, ISF, commercial invoice and packing list and asks partners for anything missing. Step 5: the broker reports the clearance status and, once cleared, uploads the 7501, which Tyllus reads into duty and fee lines. Step 6: after arrival, Tyllus requests the forwarder invoice and runs a final documents check.
How does Tyllus show clearance status and customs holds?
The broker's answer appears on the shipment and on the Customs page as soon as it is given. When a shipment is on hold, the broker picks one of seven reasons: documentation issue, additional information required, customs review, customs examination, duty or payment issue, government agency review, or other with a written explanation.
- An on-hold, in-progress or not-started answer keeps the step open, and Tyllus asks the broker again for an update.
- Shipments awaiting clearance or release are counted on the Customs page.
- For Mexico, the step closes only after the broker confirms the pedimento is validated and paid and the goods are released.
- Your team can finish any customs step itself with Complete now, or send the broker the request at once with Request now.
- Automatic emails can be paused for any shipment when you handle the broker directly.
What does the Customs page show?
The Customs page brings entries, duty payments and document gaps into one view, filtered by US or Mexico workflow. The numbers come from the 7501s and pedimentos Tyllus has read, not from manual entry.
- Filed entries from the 7501: entry number, port, filed date, duty and status (Filed, Accepted, Liquidated, Needs review or Pending).
- Duty history by month or year, with every payment grouped by shipment.
- Spend by tariff code: HTS codes for US imports and TIGIE/NICO codes for Mexico, with the shipments behind each code.
- Customs cost trend comparing total customs cost, customs fees and customs duty over time.
- Summary cards for the top HTS code, the highest-duty shipment, average duty, document gaps and shipments awaiting clearance.
- Readiness per container with house and master bill numbers, ETA, broker and document completeness, plus upload, send and request actions.

How does Tyllus keep importers informed about US and Mexico rule changes?
The Import Change Radar on tyllus.com publishes plain-language briefs on US Federal Register notices and on Mexico's official gazette, the Diario Oficial de la Federación, when they affect importers. Each brief shows what was published, the relevant dates and the original notice, and anyone can read it without an account.
Use the briefs to spot a tariff, customs or document change early and agree with your customs broker on what it means for your next entries.
