3 million masks ordered by Massachusetts confiscated by US government in NY

Can anybody figure out what the reason for the confiscation is? The deepest link I see is to https://www.statehousenews.com/ but I can't see what was there due to the subscription requirement. But the more I'm searching, the more I'm getting skeptical the story is true. Otherwise, it should be on some major outlets at this point? Related links:

Very strange. CBP enforces federal laws generally, but there still must be legal authority for confiscation.

This does explain, however, the involvement of Chinese consuls general who have been thanked for successful shipments from China. CBP cannot confiscate diplomatic mail.

This is tweeted generally as fact; it needs to get cleared up.

One of those cases when no one is wrong or right

Either it happened or it didn't. Shrodinger's Cat doesn't apply to the seizure of goods at the border.
