On Thursday, Malaysian authorities release MH370's full cargo manifest as part of the preliminary report on the missing plane.
The manifest showed NNR Global transported consolidated items - 133 pieces of one item weighing 1.99 tonnes, 67 pieces of another item weighing 463 kg, for a total weight of 2.453 tonnes.
According to a report from Malaysia Chronicle, the cargo came with a precaution that it should be handled with care due to flammable components.
However, a statement from Malaysia Airlines (MAS) Sunday sparked confusion as information revealed that it was not part of the cargo manifest stated in the preliminary report.
"About two tonnes, equivalent to 2,453 kg of cargo was declared as consolidated under one master airway bill. This master AWB actually comprised five house AWB. Of these five AWB, two contained lithium ion batteries amounting to a total tonnage volume of 221 kg. The balance three house AWB, amounting to 2,232 kg, were declared as radio accessories and chargers," MAS said in a statement.
A source from MAS said that the batteries weighed less than 200 kg but they were instructed not to reveal the remaining components of the 2.253 tonnes of cargo.
"I cannot reveal more because of the ongoing investigations. We have been told by our legal advisers not to talk about it," the source said.
According to the source as reported by The Star Online, he could not name the manufacturer of the batteries.
However, another source told fz.com that it was Motorola that shipped the cargo from its factory in Penang to the KL International Airport on March 6.
According to the report, the manifest indicated lithium ion batteries but did not mention radio accessories and chargers.
The air waybill from NNR Global Logistics Sdn Bhd revealed that it shipped on behalf of its client, Motorola. In detail two loads were packed - 1,990 kg with 133 pieces and 463 kg for 67 pieces.
The first load was shipped by NNR Global Logistics and the second load was forwarded by Kerry Logistics (Malaysia) Sdn Bhd.
The source said that it was confusing for MAS not to reveal the house air waybill. MAS may not have the master air waybill and cargo manifest, but this was not the case for house air waybill.
"It is understandable that MAS cannot reveal the other two documents simply because they may not have it. As for the house air waybill and packing list, the Customs Department, the freight forwarder and the shipper should come forward and reveal them," the source told fz.com
Malaysia Airlines chief executive officer had since clarified that the lithium batteries were not hazardous.
"The dangerous threshold for lithium ion batteries is not measured by its weight but its watt per hour measurement. For instance, a handphone probably would measure 100 grams watt per hour which is not lethal. The watt per hour measurement indicates the battery activity by the hour."
However, he cautioned that companies were notorious of shipping "hidden dangerous goods" which could include flammable liquids, lubricants, corrosive and oxidizing materials.
