Entrepreneurs FirstAccelerating trade compliance operations
Sefer is the AI layer for modern trade compliance. We help importers, brokers, and trade teams classify faster, stack tariffs accurately, surface regulatory impact across your data, and stay ahead of CBP enforcement, all in one platform.
The trade compliance landscape has fundamentally changed.
For 30 years, US trade policy trended toward fewer barriers and lower duties. That era is over. Between TFTEA enforcement, Section 232, Section 301, Section 122, AD/CVD, and UFLPA, importers and brokers now operate under stacked regulatory regimes that change weekly. And when the IEEPA tariffs were struck down, the duties already collected turned into a refund opportunity nobody had budgeted for. CBP enforcement has tightened. Reasonable care expectations have risen. The tools most companies use were built for the era we left behind.
Sefer is built for what trade compliance actually looks like now.
Classification that walks the GRI, step by step.
Sefer classifies to the full 10-digit HTS code by applying the General Rules of Interpretation in order, the way a licensed broker would. Every code comes with the GRI path it followed, the CROSS rulings it relied on, and the alternatives it ruled out.
For composite and mixed goods, it surfaces the GRI 3(b) essential-character questions instead of guessing. The reasoning trail is there for your team to verify, and for CBP if they ask.
Your data, mapped against every regulatory change.
Every CSMS message, executive order, and Federal Register notice gets ingested as it publishes. Sefer continuously maps these changes against your specific entry history, your SKUs, your supply chain, and surfaces exactly what's affected, what it costs, and what to do about it. No more reading every CSMS yourself and guessing at your exposure.
One platform. Two front lines.

Best-in-class classification accuracy, ahead of frontier models.
We benchmark Sefer head-to-head against frontier AI models on real CBP CROSS rulings: published, reproducible, and updated as models ship.
Questions trade teams ask us first.
If we missed yours, a conversation is the best place to dig in.
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 team can verify the call.
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 requests exactly what it needs, processes the reply, and resumes classification. No manual chase.
Do you handle PGAs?
Yes. FDA, EPA TSCA, USDA APHIS, NHTSA, FCC, CPSC, ATF, FWS, plus state-level. Disclaimer codes pre-populated; a licensed reviewer signs off before anything is filed.
Section 232, IEEPA, Chapter 99, AD/CVD, reciprocal tariffs?
All stacked in real time with citations, so the duty number includes every applicable layer. Updates as CBP publishes CSMS and the Federal Register publishes proclamations.
