Trade Reference Explorer Changelog

April 2026

HS code lookup and reference data coverage

• Surfaced HS code validity warnings in the tariff workflow so you see when an entered HS code is expired, invalid for the selected year, or otherwise unrecognized.

Country and program coverage

• Expanded the tariff calculator from a US-only model to 122 countries, enabling duty estimation against most major importing jurisdictions.
• Added Mexico and Canada tariff logic alongside the existing US treatment so North American duty estimates can be compared side by side.

Performance, reliability, and saved workspaces

• Added automatic retries and a fallback cache for slow tariff queries so transient timeouts no longer fail the request.

March 2026

Country and program coverage

• Added Liechtenstein and Monaco to the supported countries dropdown so customs-union jurisdictions surface alongside their parent customs territories.
• Removed non-country aggregates (EU, EZ) from the entry duty calculator country dropdown so you only see selectable importing countries.

Duty calculator and tariff outputs

• Free trade agreement selection now flows through cached duty calculations, so changing the agreement updates the result without stale cache hits.

February 2026

Duty calculator and tariff outputs

• Moved the Unit Count field into the main entry form and added a dynamic unit-type label so the requested unit (for example, kilograms, dozens, or square meters) is always visible.
• Section 232 automotive and medium/heavy-duty vehicle penalties now apply only to entries classified for automotive use, removing false-positive penalty additions on non-automotive goods.
• Honored the user-supplied loading date in duty queries instead of overwriting it with the as-of date, so historical and forward-dated entries return the correct rates.

January 2026

Duty calculator and tariff outputs

• Deduplicated Special Program Indicator and Free Trade Agreement program rows in the duty calculator so each eligible program shows once.

Sidebar, page chrome, and embedding

• Added embedded-session authentication handling so the trade reference explorer can be loaded inside partner and customer applications with single sign-on context.

Performance, reliability, and saved workspaces

• Migrated the trade reference explorer to asynchronous reference-data queries with a connection pool, improving responsiveness under concurrent load.
• Added a distributed cache so repeat HS, country, and duty lookups return faster across sessions and users.

December 2025

Sidebar, page chrome, and embedding

• Updated in-app copy in the trade reference explorer and its sidebar from prior Atlas and Copilot names to Altana and Agent.

Performance, reliability, and saved workspaces

• Reduced database lock contention on duty calculations so concurrent users no longer slow each other down.
• Fixed an infinite loop and placeholder-value bugs that could prevent results from loading, and hardened the cache against missing provenance data.

October 2025

Duty calculator and tariff outputs

• Aligned the duty calculator so the frontend always renders the same calculation the backend returns, removing mismatches between displayed and underlying duty values.
• Fixed the duty calculator so the quota indicator only appears on entries that are actually subject to a quota.

September 2025

Country of origin and USMCA workflows

• Country of origin and USMCA results now stream in progressively as they compute, so you see partial data immediately instead of waiting for the full query to finish.
• Reorganized the trade reference explorer results into a long-format table so multi-country, multi-program comparisons are easier to read and export.
• Added deep linking to specific trade reference explorer states and side-by-side duty comparison across multiple importing countries.

Performance, reliability, and saved workspaces

• Sped up loading of saved trade reference workspaces so previously prepared entries reopen significantly faster.

August 2025

Launch and major milestones

• Major upgrade delivering duty calculator v1, an expanded USMCA calculator, and an initial Partner Government Agency (PGA) flow.
• V1 milestone bringing together country of origin v1, USMCA v2, duty calculator v1, PGA v0.1, and a first version of the entry calculator in a unified workflow.

July 2025

HS code lookup and reference data coverage

• HS reference data now pulls directly from the latest Altana reference data, so HS code, tariff, and program data stays current.

June 2025

Launch and major milestones

• Initial release of the trade reference explorer as a USMCA and HS duty demo applet for exploring HS reference data, USMCA qualification, and duty estimates.

Sidebar, page chrome, and embedding

• Restructured the trade reference explorer page so the browser tab and in-app header show a proper page title.
