Your certified wood may be hiding liquid cocaine — and the Federal Revenue Service has just uncovered the largest scheme of its kind ever seen in Brazil. Operation Timber Shield seized 260 tons of wood in eight trucks at the Bolivian border on Sunday (21), with preliminary tests confirming cocaine impregnated in the fibers. If the Federal Police's forensic analysis confirms the provisional estimate — between 20 and 50 tons of pure drug — it will be the largest cocaine seizure in the country's history, surpassing the 36 tons found in 2021 in a soy truck in Mato Grosso do Sul. ?

"Com base em ocorrências anteriores envolvendo o mesmo método de ocultação, estima-se que entre 10% e 20% do peso da carga possa corresponder a substâncias ilícitas. As perícias preliminares apresentaram resultado positivo para cocaína. Caso a hipótese seja confirmada pelas análises técnicas em andamento pela perícia criminal da Polícia Federal, o volume potencial atingirá várias toneladas de cocaína, podendo variar aproximadamente de 20 a 50 toneladas de cocaína."
"A maior apreensão de drogas do país havia ocorrido em 2021, quando a Polícia Militar Rodoviária localizou cerca de 36 toneladas escondidas em uma carreta de soja no estado de Mato Grosso do Sul."
The estimate of 20 to 50 tons comes from a historical calculation: according to the Federal Revenue, "based on previous occurrences involving the same concealment method, it is estimated that between 10% and 20% of the cargo's weight may correspond to illicit substances." Four trucks were detained in Corumbá (MS) and another four in Cáceres (MT) on the 21st, after intensified inspections starting June 19 based on intelligence shared by the US and Bolivia. The Federal Police formally assumes custody of the drug and will conduct the criminal investigation, with technical analyses underway for "final determination of the drug volume found." ?

"A partir de informações de inteligência compartilhadas, foram adotadas medidas imediatas de monitoramento e fiscalização na faixa de fronteira ocorreram no dia 19/06/2026, resultando na retenção no dia de hoje de 8 caminhões carregados com madeira, distribuídos da seguinte forma: • Corumbá (MS): 4 caminhões (~130 toneladas) • Cáceres (MT): 4 caminhões (~130 toneladas)"
"A Polícia Federal foi acionada e por meio da perícia criminal federal está confirmando a existência da Cocaína... A Polícia Federal conduzirá a investigação criminal da carga apreendida e assume formalmente a custódia da droga no âmbito criminal para a apuração final do volume da droga encontrada."
The chemical impregnation technique is sophisticated: according to the Chilean Public Prosecutor's Office and Bolivian sources interviewed by Mongabay Latam, the wood undergoes extreme dehydration in intense heat, then is subjected to vacuum and pressure to introduce liquid cocaine into the pores and fibers; at destination, chemical solvents, acids or bases dissolve the drug for separation via filtration, crystallization and evaporation. The same route was used in a Chilean seizure of 100 tons on June 6 — the world's largest to date — and US intelligence indicates that both shipments originated from the same production site in Bolivia. ✓

"Según la Fiscalía chilena, primero se realiza una fase de deshidratación de la madera, que es sometida a calor extremo para retirar toda su humedad. Luego se pasa por un proceso de vacío y presión, en el que se introduce la droga en estado líquido en los poros y fibras de la madera. Para extraer la droga en el lugar de destino, aplican el mismo proceso de manera inversa. Utilizan solventes químicos, ácidos o bases para disolver la droga y luego separarla de la madera mediante filtrado, cristalización y evaporación."
"No último dia 6, a Aduana do Chile apreendeu 100 toneladas de cocaína vindas da Bolívia no mesmo esquema detectado neste domingo pela aduana brasileira — com cocaína líquida misturada na madeira. Essa foi a maior apreensão já vista. Informações compartilhadas pelos EUA apontam que as duas apreensões, no Chile e no Brasil, estão relacionadas entre si e têm origem no mesmo local de produção na Bolívia."
Finance Minister Dario Durigan called the operation a "firm response from the Brazilian State to the sophistication of criminal organizations operating in international drug trafficking" and highlighted "the importance of integration between intelligence, customs inspection, criminal investigation and international cooperation." The Federal Revenue reported that "the shipments remain under inspection, with technical and forensic procedures underway, aimed at confirming the presence and quantity of narcotic substances." ≈

"É uma resposta firme do Estado brasileiro à sofisticação das organizações criminosas que atuam no tráfico internacional... A Operação Timber Shield mostra a importância da integração entre inteligência, fiscalização aduaneira, investigação criminal e cooperação internacional"
"As cargas permanecem sob fiscalização, com procedimentos técnicos e periciais em andamento, visando à confirmação da presença e da quantidade de substâncias entorpecentes."
Eight trucks transporting approximately 260 tons of wood were seized on 06/21/2026 in Corumbá (MS) and Cáceres (MT), with preliminary tests confirming presence of cocaine
The operation involved international cooperation between Brazil, the United States, and Bolivia, with the US DEA and the Bolivian FELCN participating in shared intelligence
A Chilean seizure of 100 tons of cocaine on June 6, 2026 used the same wood-concealment method and, according to US information, originated from the same production site in Bolivia

The previous Brazilian cocaine seizure record was 36 tons in 2021, found by the Military Highway Police in a soy truck in Mato Grosso do Sul
The technique involves extreme dehydration of wood in intense heat, followed by liquid cocaine impregnation via vacuum and pressure into pores and fibers; at destination, chemical solvents extract the drug through filtration, crystallization and evaporation

-
What is the exact confirmed volume of cocaine after completion of the Federal Police's chemical forensic analysis?
Why it's still unknown: The federal forensic analysis is still underway; only preliminary tests were completed as of 06/22/2026, confirming the presence of cocaine but without final quantification.
-
Who are those responsible for the trafficking operation — individuals, transport companies, identified criminal organizations?
Why it's still unknown: The Federal Revenue and Federal Police have not released identities or names of those under investigation; the criminal investigation is in its early stages.
-
What was the planned final destination for the shipment — Brazilian ports, specific international markets?

-
Did the wood have environmental certification or regular tax documentation? If so, how was certification circumvented?
Why it's still unknown: No official or press sources mentioned aspects of forestry certification or tax compliance of the shipment.
-
How many times has this chemical impregnation technique been detected in Brazil before June 2026?
Why it's still unknown: The Federal Revenue mentioned 'previous occurrences involving the same method' to calculate the 10-20% estimate, but did not quantify or date these occurrences.
