Post-Classification Trade Flags

The checks that follow a settled HTS code: Chapter 99 trade-remedy provisions whose U.S. notes list the code, partner government agency requirements, and antidumping/countervailing duty orders whose scope cites it.

This skill runs as an MCP server in your LLM workspace and starts where tariff classification stops. Given a settled 10-digit HTS code it returns the Chapter 99 trade-remedy provisions whose U.S. notes list that code, the partner government agencies whose published import requirements reach its chapter or heading, and the antidumping/countervailing duty order notices whose published scope cites it — each with the note citation, the country named and the duty text, so you can read the source yourself. Proofwork never calls a model. It is a research aid, not legal or customs advice.

• Partner government agencies whose published import requirements reach this code's chapter or heading
