Is the ban leaking? Graphite anode trans-shipment & capacity-relocation via Indonesia

Second material in the circumvention track (R72), companion to the antimony case. The price wedge measures scarcity (what a controlled material costs ex-China). This case measures the other half: is the control actually holding, or is Chinese-controlled material re-entering the US through a laundered or relocated origin? This is a DUAL-SCORE / alternative-track signal — never folded into any Tier-1 exposure score. The divergence between "who China's graphite dependency runs through" and "what country-of-origin the customs line now says" IS the signal. Research, not investment advice; origin-relabelling is INFERRED from statistical implausibility plus public ownership records, never asserted as smuggling on any single shipment.

Verdict

Chinese battery-anode graphite is under a two-sided squeeze: China licenses its export (MOFCOM Announcement 33, effective 1 Dec 2023 — natural flake, spherical, and high-purity synthetic anode graphite) while the US taxes its import (preliminary antidumping duty of 93.5% on Active Anode Material from China, 17 Jul 2025, plus countervailing duties — escalating toward ~160–220% total by the Feb-2026 final determination). Shipping anode graphite directly China→US became economically toxic in 2025. US customs data shows the release valve, and it points at one country that mines essentially no graphite: Indonesia.

The natural-graphite line (HS 250410) tells the same story from the other end:

Source: UN Comtrade (reporter USA, annual, HS 380110 artificial/colloidal graphite and HS 250410 natural graphite in powder/flake), pulled via the free public preview API. Net weight is gross product weight. The preview endpoint returns a capped partner subset and did not return a World-aggregate row for 250410/2024 (marked n/a); the China and Indonesia partner lines for that cell are present and used as-is.

Indonesia goes from zero to the US's #2 supplier of artificial graphite (24% of imports) and a top-4 supplier of natural graphite in a single year — exactly as China's direct share of artificial-graphite imports halves from 74% to 39%. Per USGS Mineral Commodity Summaries 2026, Indonesia does not appear on the list of natural-graphite producing countries at all (China 1.4 Mt, Madagascar, Tanzania, Brazil, Mozambique, Russia, India, Canada, North Korea, Norway) — yet USGS itself notes Indonesia became a leading source (~31%) of US graphite battery-anode-material imports in 2025. A country that mines no natural graphite becoming a top US graphite supplier in the same year the direct China line is taxed shut is the textbook implausible-origin fingerprint.

The corporate pipe (the common-ownership / capacity-relocation tell)

This case exposes a second mode of circumvention distinct from the antimony case, and honesty requires naming it. Antimony surged through Thailand, a country with genuinely no antimony capacity — pure relabelling of the same molecules. Indonesia's artificial-graphite surge is different: it rides on real, newly-built, Chinese-owned capacity.

Entity/plant facts: BTR press release via PR Newswire ("BTR's Indonesian Facility Becomes Largest Anode Plant Outside China", Aug 2024); S&P Global / CIlive; Jakarta Globe; electrive. US-side trigger: US Commerce Dept preliminary AD determination on Active Anode Material from China (Federal Register, 2025; final affirmative CVD Feb 2026).

So the fingerprint here is dominated by layer 2 (common ownership), not layer 1 (volume implausibility): a Chinese anode giant re-routed serving-the-US volume through its own offshore leg, keeping the dependency intact under a new flag. Because Morowali is genuine capacity, 34 kt of Indonesian artificial-graphite exports is plausible real output — the volume-implausibility test is weak for the synthetic line and I do not claim those tonnes are relabelled Chinese molecules. What flips is the origin label, not the ownership or the technology: "Made in Indonesia" anode from a Chinese-owned, Chinese-operated plant is still Chinese supply-chain dependency. The natural-graphite line (HS 250410) is the harder-to-explain leg — BTR's synthetic plant does not produce natural graphite, so Indonesia's 0→8,603 t natural-graphite surge against USGS-confirmed ~zero domestic mine output is more consistent with processing/relabelling of imported flake. That leg I flag as implausible-origin; the exact routing is an open question.

What is inference vs. sourced: the trade table is Comtrade (country-level). The BTR–Morowali relocation is separately documented. Joining the two — i.e., attributing the specific Indonesia→US customs tonnage to BTR — is inference (Comtrade reports countries, not companies); it is strong given BTR is by far the dominant new anode capacity in Indonesia, but it is not a shipment-level proof and is presented as the worked mechanism, not a per-shipment accusation.

Why it matters for the buyer

1. Country-of-origin data is compromised for controlled graphite. A risk team reading "US graphite-anode imports from China fell from 74% to 39%" would conclude the battery-anode dependency is diversifying. Nearly all of the "diversification" is one Chinese-owned plant in Indonesia. Any exposure model keyed on stated origin over-credits the de-risking; the Chinese-ownership cross-check is the correction. 2. It confirms the squeeze is binding. Relocation and relabelling only pay when direct shipment is genuinely blocked — the same fact the widening China–West graphite/anode price wedge prices. Flow re-routing and the wedge are two independent readings of one thing: the tap is real. 3. It is a leading indicator of enforcement risk. US Commerce has active anti-circumvention scope over third-country routing of Chinese anode material; the FEOC / IRA §30D rules turn Chinese ownership (not just origin) into a disqualifier. A buyer sourcing "Indonesian" anode today should know the beneficial owner — that is where the supply chain breaks next.

Method & honesty rails

• Trade data: UN Comtrade, US imports, annual, HS 380110 (artificial/

colloidal graphite) and HS 250410 (natural graphite, powder/flake). Preview API returns a capped partner subset; late-2025 months may still revise upward.

• Production baseline: USGS Mineral Commodity Summaries 2026 (Graphite,

Natural) — Indonesia absent from the producer table; China ~1.4 Mt and >90% of spherical/artificial anode material.

• Two modes, labelled: (A) trans-shipment relabelling — surge from a

country with ~zero capacity (antimony→Thailand; and the natural-graphite leg here). (B) capacity relocation to an owned offshore leg — a controlled producer builds real capacity abroad and ships under the new flag (graphite→ Indonesia via BTR). Both defeat an origin-keyed exposure score; only (A) is relabelling of the same molecules. This case is dominated by mode (B).

• Alternative-track only: never touches buyerRelativeScore or the base

exposure — it sits next to them, like the China–West price wedge.

• Inference, not accusation: relabelling/relocation is inferred from

USGS-zero production plus public ownership records. No individual shipment is asserted illegal beyond what the cited public record states.

• Generalises (R72 Slice 2): the two-layer detector — (a) imports from origin

X of controlled material M exceed X's plausible production baseline post-control; (b) exporter-of-record ↔ Chinese common ownership — applies across the MOFCOM-controlled set. Antimony is the pure-relabel template; this is the capacity-relocation template.
