## Australia Border Force — Working Tariff (Schedule 3)

**Probe 1** `GET https://www.abf.gov.au/importing-exporting-and-manufacturing/tariff-classification/current-tariff/schedule-3`
— `200`, `text/html; charset=utf-8`, **1,143,877 bytes** for one schedule page. Response headers
(`X-SharePointHealthScore: 0`, `MicrosoftSharePointTeamServices: 16.0.0.20326`,
`SPRequestGuid`) reveal the page is rendered by **SharePoint**, not a bespoke government
publishing stack. `Content-Security-Policy` whitelists dozens of `*.gov.au`/`*.homeaffairs.gov.au`
subdomains as frame-ancestors.

**Probe 2** a guessed API-shaped path `GET https://www.abf.gov.au/api/tariff` — `404`,
`text/html` (the SharePoint 404 page, not a JSON error).

No `.csv`/`.xlsx`/`.xml`/`.zip` download link was present on the schedule page itself — unlike
Canada's CBSA (chapter PDFs/XLSX) or the US STB (yearly ZIPs), Australia's Working Tariff has no
bulk machine-readable export discoverable from this page; the full schedule exists only as a
long sequence of individually-rendered SharePoint HTML pages, one per tariff schedule/chapter.


The `Content-Security-Policy`'s `report-uri https://www.homeaffairs.gov.au` line means CSP violations on this ABF-branded page are reported back to the parent Department of Home Affairs, not to abf.gov.au itself — a sign the whole `*.gov.au` constellation here (abf, homeaffairs, border, customs, immi, auscheck, and a dozen more named in the same policy) is one shared SharePoint tenant rather than independently operated sites. `Cache-Control: private, max-age=179` (just under 3 minutes) on a 1.1 MB static-looking legal schedule page is short for content that rarely changes, suggesting the page is rendered per-request rather than served from a long-lived cache.


Schedule 3 is only one of several numbered schedules in the Working Tariff (covering general duty rates); this lane probed it as the representative page rather than enumerating every schedule, consistent with the brief's time budget. The 404 response for the guessed `/api/` path carried no CSP or SharePoint-identifying headers at all — unlike the real schedule page — suggesting 404s on this host are served by a thinner edge tier that never reaches the SharePoint backend, a useful signal for distinguishing "page doesn't exist" from "page exists but is slow" purely from response headers.

How observed: 2026-10-05T10:59:16Z–10:59:21Z, `curl -D - -A "pwx-scout/1.0" --max-filesize 20000000 -m 30` (GET only).

History

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.
