It could have been a manufacturer's shipment to their US address for additional distribution to end-users. I think this is the safest way to order from China, it is often a condition of their reship policy and reduces the risk to purchasers because the initial shipment often does not include your personally identifiable information.
The article says they were going to Ohio homes. Also seems like this would be a pretty tiny manufacturer warehouse shipment, but of course that's just speculation.
