Is the ban leaking? Copper after Indonesia's 2025 concentrate-export ban

Trade-flow companion to the price wedge (R72). Most cases in this corpus track a consumer-side control (China, the dominant refiner, cutting off a buyer) and ask whether banned material re-enters the buyer through a laundered origin (mode A — same molecules, new flag). Copper is the corpus's third Indonesian *hilirisasi* / forced-downstreaming case and the capstone of the trilogy: nickel (2020 ore ban), bauxite (2023 ore ban), and now copper (concentrate ban, hard cutoff 31 Dec 2024 → full prohibition 1 Jan 2025 under Permendag 10/2024).

The value of running it after nickel and bauxite is that both siblings landed on the same answer — a producer-side ban did not leak the raw material out under a neighbour's flag; instead the refining step was rebuilt inside Indonesia by its *Chinese* owners, so the refined product ships under a genuine Indonesian origin that is nonetheless Chinese-controlled (mode B, capacity relocation). That "genuine origin masks Chinese control" blind spot is what makes a China-de-risking buyer misread Indonesian nickel/alumina as safe.

Copper breaks the pattern — and that is the finding. The relocation is just as real (concentrate exports are being converted to onshore refined cathode), but the two smelters that absorb the banned concentrate are Western/state-Indonesian, not Chinese: PT Freeport Indonesia's Manyar/Gresik smelter (majority MIND ID, the Indonesian state holding, with Freeport-McMoRan as minority partner) and PT Amman Mineral's Sumbawa smelter (IDX:AMMN, Indonesian). The one Chinese copper-smelter deal for this stream — Tsingshan's ~$2.8 bn plan with Freeport — collapsed, and the project reverted to the Freeport-owned Gresik site. So for copper, the divergence that defines nickel and bauxite — origin Indonesia / control China — is absent. Indonesian copper cathode is genuinely less China-entangled than Indonesian nickel or alumina.

This is a DUAL-SCORE / alternative-track signal — never folded into any Tier-1 exposure score. Research, not investment advice. Nothing here alleges smuggling: the relocation is overt and legal, and the only 2025 "leak" is a government-issued export permit.

Verdict — GATE 0 (mode B confirmed; China-ownership blind spot tested and REJECTED; the only leak is a legal discretionary permit)

Under Permendag 10/2024 (30 May 2024) Indonesia pushed the copper-concentrate and anode-sludge export cutoff to 31 Dec 2024, after which the items sit on the permanent prohibited-export list — the copper leg of the hilirisasi doctrine begun with nickel (2020) and bauxite (2023). Indonesia is ~5% of global mined copper (Grasberg + Batu Hijau). As with the siblings, we can watch the flow on both sides, but with an important honesty caveat: the ban year (2025) is not yet in the customs record — Indonesia does not report 2025 monthly/annual to UN Comtrade yet, and China's 2025 mirror is also unposted. So the pre-ban baseline is fully traced; the ban-year collapse is read through the discretionary-permit press + smelter-capacity arithmetic, which is why this is GATE 0, not GATE 1.

Values are gross product value; tonnages are net weight. 2025 is not yet reported by either Indonesia or China in the preview dataset.

Read the table with the ban timeline: the hard cutoff was 31 Dec 2024, so 2024 is the last full legal-export year — Indonesia still shipped 2.47 Mt / ~$8 bn of concentrate, and China alone took 0.54 Mt. The refined-copper line already shows the relocation beginning: HS 7403 exports jumped from 144 kt (2023) to 250 kt (2024) — the first pull of the Manyar and Sumbawa smelters commissioning mid-2024. The concentrate-to-cathode conversion is real and underway.

The 2025 "leak" is a legal permit, not a laundered flag

Copper produced no phantom origin. Concentrate is a bulk mineral cargo that cannot be re-flagged the way antimony ingots or magnets can, and — critically — there was no need to launder anything, because the executive kept the flow legal:

• After a fire at Freeport's Manyar gas-cleaning plant in October 2024 halted

smelter ramp-up, Freeport's concentrate stockpile hit ~400 kt and the mine fell to ~40 % operating rate. Freeport had not exported since its last permit expired end-2024.

• Via Permendag 8/2025 (6 Mar 2025) Indonesia opened a **force-majeure export-

permit carve-out. On 16 Mar 2025 the Prabowo cabinet approved a relaxation letting Freeport export ~1.3 Mt of copper concentrate over six months (to end-June 2025) — roughly 150–200 kt/month** — explicitly to drain the stockpile while the smelter was repaired.

So the ban is nominally "in force" but the concentrate keeps flowing under a government permit — a governance / enforcement-gap leak, the same discretionary- enforcement architecture seen on the SA-chromium front-running case, not a trans-shipment relabel and not a common-ownership shell. There is nothing to prove because nothing is hidden.

Why the nickel/bauxite blind spot is ABSENT here — the ownership tell

The reason copper diverges from its siblings is who financed the onshore capacity:

The divergence that IS the signal for nickel and bauxite (stated origin Indonesia vs. underlying control China) therefore does not exist for copper: the refined cathode leaving Indonesia is genuinely Western/state-Indonesian-controlled. A China-de-risking buyer sourcing Indonesian copper cathode is not walking into the hidden-Chinese-control trap that Indonesian Class-1 nickel or alumina represents.

This is what makes copper the trilogy's counter-example: it confirms the hilirisasi doctrine generalizes to a third, chemically unrelated commodity (a settled cross-administration industrial policy — Jokowi → Prabowo), but it isolates the mode-B China-control blind spot as a function of smelter ownership, not of the ban itself. Where China financed the onshore step (nickel, bauxite), the blind spot is present; where the West/state did (copper), it is absent. The ban is not the risk — the financier of the relocation is.

Transmission chain

Controlled origin (Indonesian mine, Grasberg/Batu Hijau) → concentrate export banned 1 Jan 2025 → NOT re-flagged through a transit country (bulk cargo; no phantom origin) → refining relocated onshore to Manyar + Sumbawa → refined cathode ships under genuine Indonesian origin that is genuinely Indonesian/Western- controlled → meanwhile a legal discretionary permit (~1.3 Mt, H1-2025) keeps some concentrate flowing to Japanese/Korean/Chinese custom smelters while Manyar is repaired.

What it implies for the Tier-1 score's blind spot

• For nickel and bauxite, the Tier-1 lesson stands: a stated Indonesian origin

can hide Chinese control, and the exposure score must not treat "sourced from Indonesia" as "de-risked from China."

• For copper, the opposite correction applies: the Tier-1 score should not

over-penalize Indonesian copper cathode as China-adjacent. The onshore capacity is Freeport/MIND ID/Amman; the Chinese smelter deal for this stream fell through. Copper is the case where hilirisasi is pure resource nationalism without the China-laundering overlay.

• The residual near-term risk is not laundering but enforcement discretion: the

permitted-concentrate volume (1.3 Mt H1-2025, and any Amman extension if Sumbawa slips) is the real leak to watch, and it is published, not hidden.

Caveats (honest)

• Inference, not proof; and detector-negative on both fingerprints. No mode-A

phantom flag exists (bulk concentrate), and the mode-B ownership tell is rejected (Western/state, not Chinese). The "signal" here is the absence of the sibling blind spot plus a legal-permit governance gap — valuable precisely because it corrects an over-broad "Indonesia = China proxy" prior.

• Data lag → GATE 0. The 2025 ban-year collapse is not yet in UN Comtrade

(Indonesia and China 2025 both unposted); the pre-ban baseline (2021–2024) is fully traced, but the collapse is read through the discretionary-permit press and smelter-capacity arithmetic. Re-open when 2025 customs data posts (expected 2026) to confirm the concentrate line zeroes ex-permit and the HS 7403 cathode line steps up toward Manyar's ~600 kt + Sumbawa's ~220 kt nameplate.

• Single-shipment innocence. Nothing here alleges wrongdoing by any operator; the

permit is lawful and the relocation is overt.

• Open question — by-product streams. Grasberg/Batu Hijau concentrate carries

significant gold and silver; whether the by-product refining (previously routed through Japanese custom smelters) is captured onshore, and under whose control, is a separate thread worth its own case.
