Jason Tranter, 38, was denied bail at Mt Gambier Magistrate's Court on Friday and was remanded until 9.30am on Monday.

Australian Federal Police have charged Tranter with having imported a commercial quantity of a border controlled precursor, namely pseudoephedrine.

The court heard on Friday that Customs and Border Protection officers noticed anomalies in a sea cargo consignment from Thailand when it arrived in Port Adelaide on May 5.

Customs and Border Protection and AFP Forensic members examined the consignment of marble items including two stools, a vase and bowl and found three plastic bags containing a variety of tablets inside.

Australian Federal Police agents monitored the consignment as it was transported to Naracoorte, and then searched Tranter's Neuarpurr property on Friday where the marble items were located.

Tranter was arrested after the marble items were allegedly found broken open.

Australian Federal Police allege Tranter knowingly imported pseudoephedrine into Australia.

An Australian Federal Police spokeswoman said the maximum penalty for the offence was 25 years imprisonment.

•Tranter, who grows onions and potatoes on his Neuarpurr farm, has a high profile in the agricultural industry through his involvement in various farming sectors including dairy and wine.

He is a former winner of National Australia Bank Young Agribusiness Achievers Awards for West Wimmera Shire.
