## EU TARIC consultation (ec.europa.eu/taxation_customs/dds2)

**Probe** `GET https://ec.europa.eu/taxation_customs/dds2/taric/measures.jsp?Lang=en&SimDate=20261005&Taric=0101210000&StartPub=&EndPub=&MeasType=&Regulation=&Origin=&LevelMeasure=&OrderNum=&Area=&MeasText=&LangDescr=&SimRegul=false`
— `200`, `Content-Type: text/html; charset=UTF-8`, 79,917 bytes, `Server: Europa`. The response
sets `Set-Cookie: client_nr=…` and `JSESSIONID=…; HttpOnly` — a stateful Java servlet session on
what looks like a stateless query-string lookup. Body `<title>TARIC Measure Information</title>`,
rendered as an HTML `<table>` of measures (`Measure type`, duty rates, regulation references).

There is no JSON/XML sibling endpoint discoverable from this page or its query parameters —
TARIC's only machine-consumable surface is the full nomenclature/measures **bulk XML export**,
a separate dated-file download (not probed here to respect the light-client body-size budget),
distinct from this HTML consultation screen. Every parameter (`SimDate`, `Taric`, `MeasType`,
etc.) is a plain query-string field on a `.jsp` page unchanged in shape since the legacy "dds2"
system name.

Contrast: this is the one tariff system in this lane's cluster with **zero** REST/JSON surface —
USITC HTS, UK Trade Tariff, and WITS all answer JSON or SDMX-XML to a plain GET; TARIC answers
only server-rendered HTML with a servlet session.


The response is also notably uncompressed and uncached at the edge: no `Content-Encoding`, `Cache-Control`, or CDN header of any kind appears on the 79,917-byte HTML payload, unlike every other government source in this lane (STB, FMCSA, CBSA) which all sit behind some CDN or edge cache. `Transfer-Encoding: chunked` with no `Content-Length` means a client cannot pre-size a buffer for the page. A comment embedded in the HTML (`<!-- File modified for QTM132 CR#CUSTD00027346(NVI)-->`) leaks an internal change-request ticket number into the public response — a small but real provenance detail about how this legacy system is maintained.

How observed: 2026-10-05T10:58:23Z, `curl -D - -A "pwx-scout/1.0" --max-filesize 20000000 -m 30` (GET only).

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
