Twenty two workers were stood down amid the stand-off between the Maritime Union of Australia and the stevedore on Tuesday and another 40 were stood down on Wednesday.
DP World argued the Australian Border Force deemed the vessel compliant and the 14-day rule only applies to ships from mainland China, the Republic of Korea, Italy and Iran.
The company said chemicals for soap and detergent manufacturing, medical supplies, surgical masks, gloves surgical gowns, lab coats and hair nets are aboard the ship now sitting idle at the port. Tinned foods for supermarkets and whitegoods were also being transported.
DP World's chief operating officer Andrew Adam said the vessel had been cleared to berth at DP World by the Australian Border Force and the Department of Agriculture, Water and the Environment’s Biosecurity.
“The directions are very clear, and we don’t make the rules, these are defined by Australian Border Force. Any crew members aboard a vessel that has been to mainland China, must have been at sea for 14 days before they are allowed to dock in Australia," Mr Adam said.
"The vessel left Shanghai in China on March 17 and arrived in Melbourne on March 31. It has been out of sea for 14 days. The union is not allowed to unilaterally declare a vessel unsafe: they are not allowed to create their own set of rules.”

But Warren Smith, the union's assistant national secretary, said all vessels should be quarantined for a 14-day period if they arrive from an overseas port and it was wrong to stand down workers who were trying to prevent the spread of the virus.
"It is ridiculous that these workers have been stood down and had their livelihoods threatened for standing up and doing the right thing," Mr Smith said.
