Does Santa have MFN status?

Dingel reports:

The US nominal average ad valorem tariff rate for (12 Days of) Christmas this year, which I calculated using the handy Harmonized (Tariff) Christmas schedule, is only 1.9%. I assume that Santa has MFN status.

Drums 4.8%
Pipes 0%
Milking machines 0%
Swans 1.8%
Geese $.02/kg
Golden rings 5.5%
Calling birds 1.8%
French hens $.02/kg
Turtle doves 1.8%
Partridge 1.8%
Pear tree 0%

I thank Alex Thiele, a loyal MR reader.  But I believe the optimal tariff on drums is zero.
