SANTIAGO, CHILE — Chile’s largest drug seizure in its history has become the subject of a genuine dispute between two governments over whether the drugs were actually there at all.
A Record-Breaking Seizure
In June, Chilean authorities announced they had intercepted 45 shipping containers at the northern port cities of Arica, San Antonio, and Valparaíso carrying roughly 1,080 tons of sawn timber from Bolivia — timber that laboratory testing determined contained between 10% and 20% of its total volume in cocaine hydrochloride and ketamine, chemically impregnated directly into the wood itself.
Officials estimated the seizure at 108 tons of drugs with a final-market value near $8.3 billion, calling it the largest interdiction of its kind in Chilean history and the largest of this specific smuggling method ever recorded worldwide.
The investigation, led by the Arica Regional Prosecutor’s Office alongside Chile’s Maritime Police and National Customs Service, ran more than six months and traced the shipments to sawmills across Bolivia’s Pando, Santa Cruz, Cochabamba, Beni, and La Paz departments, using wood from tajibo (lapacho) and almendrillo trees — a method authorities described as sophisticated and specifically designed to evade conventional detection.
The network allegedly intended to distribute the shipments through at least 14 international ports; one container bound for Miami reportedly also tested positive for drug traces.
Bolivia Launches Its Own Investigation — Then Disputes the Findings
Bolivia’s government initially treated the case seriously. Interior Minister Marco Antonio Oviedo announced a joint investigation with Chilean authorities, and by mid-June a civilian-police operation was raiding sawmills and exporting companies across Santa Cruz, Pando, Beni, and La Paz, with plans for roughly 50 total interventions and an expected expansion into Cochabamba.
Bolivian legislators from Oruro called for a special parliamentary investigating commission, though opposition Senator José Sánchez raised concerns about the commission being dominated by government allies.
In the weeks since, however, Bolivia’s executive branch has reversed course dramatically. The Ministry of Government released a statement claiming that specialized laboratories in Chile and Brazil had concluded the seized timber shipments were entirely legitimate cargo, containing no drug impregnation whatsoever, and demanded the immediate release of the detained trucks and cargo.
Chile’s prosecutors are not backing down, however. The Arica and Parinacota Regional Prosecutor’s Office issued a terse statement rejecting any suggestion the case was closed, stating plainly that the “impregnated wood” investigation remains active, with ongoing diligences, and that no further public comment would be made given the case’s standing under investigative secrecy.
That the case remains open, per Chilean authorities, directly contradicts Bolivia’s public position that the matter has already been scientifically resolved in its favor.
Not Bolivia’s First Time
This is the third time in three years Chilean customs has intercepted cocaine hidden in Bolivian timber shipments using this method. A smaller bust in July 2023 found roughly two tons of cocaine impregnated into 530 wood planks crossing at the Chungará border post, also bound for Europe. A second interception followed in March 2026, before June’s seizure became by far the largest of the three — and, per Chilean authorities’ own characterization, the largest bust of its kind ever recorded globally.
Why the Dispute Matters
Beyond the immediate question of guilt or innocence, the standoff carries real economic stakes for Bolivia’s timber export sector: Bolivia’s National Chamber of Exporters has voiced concern over damage to the country’s foreign trade reputation, while the National Forestry Chamber has pushed back against tarring the entire legitimate timber industry over the actions of the 15 exporting companies whose containers were flagged.
Bolivia’s Attorney General, Roger Mariaca, has said his office would investigate separately, in part because Chilean authorities’ initial findings were not shared through official government channels — an unusual procedural wrinkle for a case now central to Bolivia’s broader security cooperation push with the United States and the region.
For now, the case sits in an unusual limbo: Bolivia’s executive branch publicly declaring the matter resolved and demanding restitution, while Chile’s own prosecutors insist the investigation is very much alive and decline to engage publicly with Bolivia’s counter-claims.
Given the sheer scale of the alleged seizure — the largest drug bust in Chilean history, by volume — and its timing alongside Bolivia’s broader push to rebuild security credibility with Washington and its regional neighbors, how this dispute resolves is likely to say as much about the strength of Bolivia’s new anti-crime commitments as any diplomatic agreement signed so far this year.
