Myanmar (Wa State) Comprehensive Tin Mining Suspension — Wa Jing Zi No. 2023-06

Mechanism

Wa State (Special Region No. 2) is an autonomous territory administered by the United Wa State Army (UWSA) in eastern Shan State, Myanmar. Although formally within Myanmar's borders, the UWSA operates its own government, military, and economic-planning apparatus largely independent of the central Myanmar government (SAC/SSPC). UWSA has no English-language official web portal; the International Tin Association (ITA) documented the specific notice numbers in contemporaneous reporting and is treated as the best-available primary documentation for §6 purposes, equivalent to cases where official text exists only in a non-indexed local-language gazette.

Notice Wa Jing Zi No. 2023-06 (April 15, 2023): Issued by the Wa State Central Economic Planning Commission; mandated immediate cessation of all mining and excavation "until mature mining conditions are in place." Workforce to be temporarily dismissed; ore transport vehicles prohibited.

Implementation Order (May 20, 2023): Confirmed August 1, 2023 as the hard effective date for all mines and processing plants regardless of size. Provided a three-month adaptation period from the original April notice.

Property-rights provision (effective August 1): Ore extracted and above-ground before August 1 remained the property of the mine operator but was subject to a 30% tax-in-kind payment upon processing. All ore still in situ below ground passed into ownership of the Economic Planning Committee. Mine owners were required to register processing plants with the Central Affairs Committee by August 30, 2023.

Pre-suspension inventory liquidation: In July 2023, exports surged as traders rushed to clear approximately 1,500 metal tonnes of tin ore stockpiled at Meng'a Port and drew down an estimated ~2 million physical tonnes of raw ore and ~5,000–6,000 metal tonnes of concentrate potential held in Wa State.

Scale

• 2022 Myanmar tin-in-concentrate production: ~40,000 tonnes total; Wa State accounted for ~70% (~28,000 tonnes)
• China 2022 imports of Myanmar tin-in-concentrate: ~48,000 tonnes
• Global supply disruption: Man Maw alone represented ~10% of global tin concentrate supply
• LME price response: 3-month tin rose ~9% in the weeks immediately following the April 15 announcement; further gains followed as the August start date approached

Downstream implications

• China's tin smelting complex (Yunnan Tin, Gejiu) absorbed the bulk of Wa State concentrate; the suspension created an acute feedstock gap for Chinese primary tin smelters with limited short-run substitution (Indonesian tin concentrate was the main alternative, but at higher cost and with lower grade)
• Global refined tin supply tightened through H2 2023, sustaining elevated LME prices
• The suspension marked the first exercise of Wa State's resource-governance authority at scale; its resolution via a structured licensing regime (February 2025) established a new royalty and export-permit template for the zone

Open questions

• Feb 7, 2024 instrument formalising the 30% tax-in-kind levy on tin concentrate exports during suspension (queue note) — file as AMENDMENT to this slug once available
• New three-year licensing regime (mid-2025) already filed separately as 2025-02-01-myanmar-wa-state-man-maw-tin-restart-licensing; that action's responds_to should reference this slug
