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.
Zambia's Ministry of Commerce, Trade and Industry gazetted Statutory Instrument No. 17 of 2026 on 20 March 2026 (effective 27 March 2026), replacing a prior outright export prohibition on sulphuric acid with a permit-based export control regime under the Control of Goods Act (Chapter 421). The instrument was triggered by an acute domestic shortage after multiple major Zambian copper smelters entered simultaneous extended maintenance shutdowns in 2025, collapsing by-product acid production. As the dominant supplier of sulphuric acid to DRC hydrometallurgical copper and cobalt mines, Zambia's restriction disrupted leaching operations across the DRC's oxide-ore processing chain. A partial easing began in May 2026 as smelter capacity recovered, with company-specific export authorisations issued to Chambishi Copper Smelter and Mopani Copper Mines.
The Zambian Minister of Finance suspended the 10% export duty on copper concentrates (HS 2603.00.21–29) effective 5 March 2026 under Section 89 of the Customs and Excise Act, providing temporary duty relief to miners whose domestic processing capacity was constrained by extended smelter maintenance cycles at Mopani/ZCCM-IH, Lumwana (Barrick), First Quantum Kansanshi, and Nkana. The suspension allows qualifying copper concentrate to be exported for offshore processing at zero duty, addressing a stockpile overhang across Zambia's copper belt that could not be absorbed by the domestic smelter fleet. A follow-on extension (SI No. 43/2026, effective 1 June 2026 through 30 September 2026) introduced company-specific quotas totalling 271,742 t and mandated channelling through Industrial Resources Limited, an IDC subsidiary.
On 18 February 2025 Tailings Dam 15 at Sino-Metals Leach Zambia Limited's Chambishi facility (Copperbelt Province, Kalulushi District) failed, releasing acidic leach residue into the Chambishi Stream and the Mwambashi and Kafue Rivers; the company suspended operations and the Zambia Environmental Management Agency (ZEMA) commissioned an independent Environmental and Social Incident Impact Assessment (ESIIA). ZEMA received the consultant's final report on 19 December 2025 and held a public disclosure meeting in Kitwe on 6 January 2026. On 2 February 2026 the Ministry of Mines and Minerals Development announced that the investigation had concluded and that, once ZEMA's review of the findings is complete, stakeholders will be engaged to determine remediation and compensation modalities. Company clean-up operations began in March 2026.
