Document intake and automated client follow-up

Email, invoices, packing lists, BOLs, and COOs parsed into one structured shipment, conflicts surfaced rather than silently picked. When something is missing, Sefer emails the importer for exactly what it needs, processes the reply, and continues classification — no more waiting-for-docs loop.

FAQ

Questions brokers ask us first.

If we missed yours, the demo is the best place to dig in.

Does Sefer replace my licensed broker?

No. Your LCB reviews and submits every output on their license and your filer code.

How accurate is the classification?

Best in class. We benchmark Sefer head-to-head against frontier AI models on real CBP CROSS rulings. It leads on heading and full-code accuracy with a lower hallucination rate. Every code ships with its GRI trail and the rulings it relied on, so your LCB can verify the call.

How does Sefer fit with 19 CFR § 111.28?

Every draft has an audit trail, every classification has cited reasoning, every rule has its CBP source. The documented basis CBP wants in a focused assessment.

What happens when shipment docs are incomplete?

Sefer parses every attachment (invoice, packing list, BOL, COO) into one structured shipment and surfaces conflicts instead of silently picking. When something is missing, it emails the importer for exactly what it needs, processes the reply, and resumes classification. No manual chase.

Who actually transmits to CBP?

Your team, through your existing ABI or ACE Portal, on your filer code. Sefer has no filer code and never transmits.

What if a Sefer-drafted entry has an error?

Same liability path as any entry your LCB signs today. The reasoning trail makes reasonable care easier to demonstrate; it doesn't shift liability.

Which ABI systems do you push into?

CargoWise, NetCHB, CustomsCity, and direct ACE Portal. Magaya in pilot. Flat ABI file export for custom stacks.

Do you handle PGAs?

Yes. FDA, EPA TSCA, USDA APHIS, NHTSA, FCC, CPSC, ATF, FWS, plus state-level. Disclaimer codes pre-populated; LCB reviews before submission.

Section 232, IEEPA, Chapter 99, AD/CVD, reciprocal tariffs?

All stacked in real time with citations, so the duty number you give your client includes every applicable layer. Updates as CBP publishes CSMS and the Federal Register publishes proclamations.
