What the 2025 INCB precursor report says about China-linked incidents—and what it does not prove

Nine reported incidents, nearly five tonnes, and one crucial missing join: the official record identifies an origin, but it does not establish a causal chain to US deaths or measure lawful industrial trade.

5 tonnes, nearly combined across nine PICS incidents
9 incidents reported in the first ten months of 2025
168 seizures four-country operation total; not a China-to-Oceania count
38,056 provisional deaths US T40.4 excluding methadone, 12 months ending December 2025

China-to-EU aggregate retained at source precision One multi-incident aggregate. The comparison value is displayed as nearly five tonnes, never as one exact shipment.

China-to-EU aggregate retained at source precision in tonnes, upper bound
Year	Record	tonnes, upper bound	Relative scale	Source
2025	multi incident aggregate9 incidents; China → European Union	5		[3]paragraph 94; PDF page 44; printed page 26

Boundary: The report says “nearly 5 tons” across nine incidents. The bar retains that less-than upper bound and is not an exact shipment mass.

Operation Pseudonym: the allocation gap The operation-wide count is retained separately because the report does not allocate it by China/India origin and Australia/New Zealand destination pair.

Year	Record	operation-wide seizures	Relative scale	Source
2024	unallocated contextFour participating countries; majority reported by Australia and New Zealand	168		[3]paragraph 46; PDF page 31; printed page 13

Boundary: Australia’s and New Zealand’s annual seizure totals are excluded from bilateral arithmetic; they are different aggregates.

methodology

The join the evidence does not permit

This analysis keeps an INCB precursor report and a CDC mortality series in separate evidence lanes because they describe different populations, units and events. [3]paragraph 94; PDF page 44; printed page 26[6]United States; 12 month-ending December; synthetic_opioids (T40.4 excluding methadone); 2015–2025

The checked inputs share no incident, shipment, exporter or case identifier that could connect the precursor aggregate to a lawful trade record or a death. [3]paragraph 94; PDF page 44; printed page 26[6]United States; 12 month-ending December; synthetic_opioids (T40.4 excluding methadone); 2015–2025[1]registered capability and access boundary; as of 2026-08-12[2]registered capability and access boundary; as of 2026-08-12

Here, “China-linked” means only that the INCB report says substances reportedly originated in China; it is not a finding about a country, industry, company or person. [3]paragraph 94; PDF page 44; printed page 26

lawful trade

Lawful industrial trade: the missing denominator

GACC publishes official merchandise-trade statistics, while UN Comtrade exposes aggregate trade by reporter, partner, product and period. [1]registered capability and access boundary; as of 2026-08-12[2]registered capability and access boundary; as of 2026-08-12

NarcoScope has not admitted a chemical-product series from either capability into this dossier, so lawful trade is not quantified here. [1]registered capability and access boundary; as of 2026-08-12[2]registered capability and access boundary; as of 2026-08-12

Those registered aggregate capabilities do not provide a public shipment-level end-use ledger, so they cannot classify an export as licit or diverted in this build. [1]registered capability and access boundary; as of 2026-08-12[2]registered capability and access boundary; as of 2026-08-12

official incidents

What the INCB report actually says

INCB reported that, during the first ten months of 2025, 9 incidents involving nearly 5 tonnes of two related methamphetamine pre-precursors were communicated through PICS. [3]paragraph 94; PDF page 44; printed page 26

The report said those substances were mislabelled, reportedly originated in China and were destined for countries in the European Union. [3]paragraph 94; PDF page 44; printed page 26

That figure is a less-than multi-incident aggregate, not an exact 5,000 kg shipment, and NarcoScope does not add it to other qualified quantities. [3]paragraph 94; PDF page 44; printed page 26

For Operation Pseudonym, INCB said four participating countries reported 168 seizures, most in Australia and New Zealand, and reported China and India as origins in those two countries. [3]paragraph 46; PDF page 31; printed page 13

The public report does not allocate those seizures or their mass by origin-and-destination pair; Australia’s and New Zealand’s annual totals are separate aggregates and are excluded here. [3]paragraph 46; PDF page 31; printed page 13[3]paragraphs 67 and 71–72; printed pages 19–20

harm

The US harm trend is real—and separate

Across every retained December checkpoint, CDC’s provisional US count involving synthetic opioids excluding methadone rose from 9,610 in 2015 to a peak of 74,829 in 2022, then fell 49.1% to 38,056 in 2025. [6]United States; 12 month-ending December; synthetic_opioids (T40.4 excluding methadone); 2015–2025

The category is “synthetic opioids excluding methadone (T40.4),” not all synthetic opioids and not a measure of precursor supply. [6]United States; 12 month-ending December; synthetic_opioids (T40.4 excluding methadone); 2015–2025

The CDC rows contain no exporter, shipment, precursor or country-of-origin field, so the series is harm context rather than corroboration of the INCB incidents. [6]United States; 12 month-ending December; synthetic_opioids (T40.4 excluding methadone); 2015–2025[3]paragraph 94; PDF page 44; printed page 26

The counts are provisional and can be revised; the chart shows every available national December checkpoint instead of selecting only three years. [6]United States; 12 month-ending December; synthetic_opioids (T40.4 excluding methadone); 2015–2025

what cannot show

The evidence gap is the finding

The official record supports one attributed finding: INCB reported a China-origin aggregate of nearly five tonnes across nine incidents bound for European Union countries. [3]paragraph 94; PDF page 44; printed page 26

It supports zero independently corroborated event claims because no second admitted source confirms the same incident set at compatible grain. [3]paragraph 94; PDF page 44; printed page 26[6]United States; 12 month-ending December; synthetic_opioids (T40.4 excluding methadone); 2015–2025

The available sources do not establish a record-level causal chain from lawful production or export to an incident, an organization or a death. [1]registered capability and access boundary; as of 2026-08-12[2]registered capability and access boundary; as of 2026-08-12[3]paragraph 94; PDF page 44; printed page 26[6]United States; 12 month-ending December; synthetic_opioids (T40.4 excluding methadone); 2015–2025

The defensible automated conclusion is therefore narrower than a national accusation: the report identifies a pattern worth investigating and the public data needed to test its consequences are missing. [3]paragraph 94; PDF page 44; printed page 26[6]United States; 12 month-ending December; synthetic_opioids (T40.4 excluding methadone); 2015–2025

countercase

Countercase and evidence still needed

The INCB aggregate and the separately declining CDC series are compatible with many explanations, including enforcement, reporting, market and treatment changes; this build cannot choose among them. [3]paragraph 94; PDF page 44; printed page 26[6]United States; 12 month-ending December; synthetic_opioids (T40.4 excluding methadone); 2015–2025

A stronger test would require a lawful-trade denominator, shipment-level regulatory notifications, incident identifiers and adjudicated outcomes with defensible shared keys.
