Forensic analysis has revealed that 2.5 kilograms of the drug ice was secreted in tea products, bars of soap and "foot care cakes" in the luggage of a man arrested earlier this year in Melbourne.

It is alleged that Sung Su Mun, 67, a South Korean national, imported a commercial quantity of the drug - with a pure weight of 1.4 kilograms - through Melbourne Airport on March 24.

According to a prosecution summary, Mr Mun, who had arrived from India, told customs officers he came to Australia for business that involved a patent for a water machine.

Melbourne Magistrates Court heard on Monday that after he was selected for a baggage examination he told the officers he packed his suitcase which contained "maybe something to do with the machine".

The summary, tendered by prosecutor Mario Camilleri, said Mr Mun stated he had lost the key to the suitcase's padlock, but officers found it in the outer zip pocket.

Magistrate Charlie Rozencwajg was told a search of Mr Mun's luggage found "small boxes of tea products, bars of soap and foot care cakes" that appeared to be "commercially sealed and shrink wrapped".

It was alleged Mr Mun told investigators that all the items in the suitcase, which included traditional Indian clothing and shoes and a golf set, were "presents" from the company he dealt with in India.

The summary said he later told customs someone else had packed the suitcase and that he was "going to hand it over to someone" at Melbourne Airport.

After presumptive testing of the white crystalline substance in the tea, soap and cakes found methamphetamine, Mr Mun asked to speak to a lawyer after which he advised he would not participate in further questioning.

The summary said he would not consent to an interview because of legal advice, he had taken medication for high blood pressure, cancer and diabetes before flying and he was "elderly and had not slept in the previous 24 hours".

Mr Rozencwajg said he was satisfied there was evidence of sufficient weight to support a conviction on the charge, to which Mr Mun pleaded not guilty.

His solicitor, Nicole Valos, confirmed there were no custody management issues other than those raised in March, that had related to his health issues.

Mr Mun, of no fixed place, who did not apply for bail, was remanded to appear for a directions hearing in the County Court on Tuesday.
