The impact

  • 90%

    classification accuracy on initial AI-assisted drafting

  • 70%

    reduction in initial research time per tariff item

  • 100%

    of drafts reviewed and signed off by senior counsel

01 The challenge

Hours of associate research behind every classification opinion.

Determining the correct harmonized tariff classification for complex industrial and chemical imports required junior associates to spend hours cross-referencing tariff schedules, judicial precedents, and explanatory notes.

Turnaround times stretched during peak filing periods, creating bottlenecks for commercial importers awaiting advisory opinions.

02 Our approach

Augment expert judgment, never replace legal sign-off.

  1. Discover

    Cataloging past rulings, tariff codes, and judicial precedents

  2. Design

    Reasoning framework, citation verification, and confidence scoring

  3. Build

    Specialized retrieval engine, prompt engineering, and validation suite

  4. Roll out

    Associate pilot and senior counsel sign-off workflow

We established strict parameters: the AI assists with first-pass research and generates structured reasoning with exact statutory citations, but never issues an opinion without senior counsel review and approval.

03 The solution

What we built

  1. Request

    product specs · invoices

  2. AI draft

    classification · reasoning

  3. Associate review

    verify citations · edit

  4. Senior counsel

    final sign-off

The system digests product descriptions, laboratory specifications, and relevant trade agreements. It cross-references current customs schedules and past rulings to produce a comprehensive classification memo complete with statutory citations and alternate classification risks.

04 The outcome

70% faster memo turnarounds with uncompromised rigor.

First-pass research time was cut by over two-thirds, allowing associates to handle three times the case volume while senior counsel maintains 100% oversight and sign-off authority.
