The central probe agency also attached, under the Prevention of Money Laundering Act (PMLA), an amount of Rs 1.75 crore kept in the account of the importer, identified as K Liakath Ali.
The Enforcement Directorate (ED) said Ali ran a firm called Ms Galaxy Impex.
He has now been lodged in the central jail in Puzhal.
Ali was arrested by the ED in a similar money laundering probe case early this year after it conducted nation-wide raids against shell companies.

"The police FIR was based on the complaint of the Indian Bank for cheating, using forged documents by certain importers. This is a case of trade based money laundering using shell companies by the traders engaged in the imports of electronic consumer goods," the agency said in a statement.
It added that the importers remitted large amount of foreign exchange out of India and subsequently cheated an Indian Bank branch here.
"In this case forged bills of entry were used in the guise of actual documents generated through electronic data interface of the Indian Customs.
The agency said Ali is the "mastermind" of this trade- based money laundering racket. It said it recovered "incriminating" documents after raids against him that revealed that forged bills of entry were used in the shell company accounts to facilitate outward remittance of foreign exchange.
"Ali was in possession of multiple PAN cards and driving licenses and he used to make minor variation in his name for opening bank accounts with various banks," it said.
