Structured register of government actions in the geoeconomic space — export controls, tariffs, sanctions, FDI screening, subsidies, industrial-policy laws — cross-referenced into the country, minerals, and ETF surface. Charter: docs/IPTM_CHARTER.md.
Severity 1-5 is the qualitative impact rating (1=minor, 5=structural). The bilateral-trade-grounded quant scorer is the next IPTM milestone. RBI (Register Breadth Index) is a complementary structural-breadth indicator from scripts/py/iptm/breadth.py; divergence between RBI and severity is itself informative (high-sev / low-RBI = strategic chokepoint; low-sev / high-RBI = broad but shallow). Every action has at least one primary source URL. Verify-or-don't-file. See also themes, timeline, graph, sankey, map, country exposure, sector exposure, material exposure (+ graph), weekly briefs, portfolio scan, escalation monitor, trans-shipment hubs. Internal triage tools (RSS-poller candidate feed, source-feed health) live under /admin/candidates + /admin/sources. Subscribe via Atom feed (accepts ?country=CN, ?material=lithium, ?issuer=BIS, ?type=export_control, ?etf=SOXX, ?company=NVDA, ?minSeverity=4, ?year=2026, ?q=…) or pull /api/iptm/actions.
On 25 October 2023 the Bureau of Industry and Security published an interim final rule (88 FR 73424; FR Doc 2023-23055) making substantive revisions to the October 7 2022 advanced-computing IFR, incorporating 43 public comments covering 78 topics. The rule replaced the prior TOPS-based performance metric with a new "Total Processing Performance" (TPP) / performance-density dual-threshold structure for ECCN 3A090, splitting the control into tiers 3A090.a (full licence requirement for highest-capability datacenter AI chips) and 3A090.b (new License Exception NAC with 25-day prior notification for the intermediate tier). Geographic scope was expanded from China-and-Macau to Country Groups D:1/D:4/D:5 to block diversion via third-country intermediaries and offshore datacenters.
The US Bureau of Industry and Security issued an interim final rule on 17 October 2023 that substantially expanded the advanced-computing and semiconductor manufacturing controls first imposed in October 2022. The rule closed the performance-threshold workaround that NVIDIA had used to ship China-specific A800/H800 GPUs, replacing it with a "performance density" metric and adding a new "Notified Advanced Computing" licence category. It expanded controls on chipmaking equipment (additional ECCNs covering deposition, etch, metrology), pulled 21 additional countries (mostly Middle East / Central Asia) into a regional licensing scheme to prevent transshipment, and added 13 Chinese entities to the Entity List including AI-chip designers.
