The drugs found in Sinsheim in the state of Baden-Württemberg in October are said to have a street value of up to 20 million euros, corresponding to over 215 million Swedish kronor.
The methamphetamine is said to have been shipped in a container from Mexico to the Belgian port city of Antwerp, hidden in a 24-ton workshop press, and then arrived in Sinsheim by truck.
Two people in their 30s who are suspected of trying to receive the drugs were arrested red-handed when the police swooped.
