“Tariffying” )tariff + terrifying) is a political portmanteau word that has been infrequently used. “Merely tariffying a country like that is never going to terrify it!” was printed in The Auto: The Motorist’s Pictorial in 1919. “TARRIFYING, The duties in the tariff bill are certainly tariffic” was printed in the Brooklyn (NY) Daily Eagle on June 2, 1922.

Wikipedia: Tariff
A tariff is a tax on imports or exports between sovereign states.

The Auto: The Motorist’s Pictorial
Volume 24
1919
Pg. 887:
... per day, and the money and time to enable it to show that its own high-class product is every bit as perfect as ours, although it is turned out at the rate of 350,000 per annum—well, merely tariffying a country like that is never going to terrify it!
       
2 June 1922, Brooklyn (NY) Daily Eagle, pg. 1, col. 2:
TARRIFYING,
The duties in the tariff bill are certainly tariffic.
   
13 March 1976, (New Orleans, LA), “News of the Week in Review” by Howard Jacobs, sec. 3, pg. 7, col. 2:
While nobody likes to pay more taxes, this particular measure doesn’t seem to be so tariffying.
 
13 February 1975, Honolulu (HI) Advertiser, Howard Case’s “Down to Cases,” pg. A-15, col. 2:
Memo from C.K.S>: “The proposed duty on imported oil is tariffying folks here in Hawaii.”
 
5 November 1993, Financial Post (Toronto, ON), “GATT end-game could pit Bloc against Reform” by William Watson, pg. 11:
GATT sees through this transparent duplicity and is having nothing of it. Our import quotas will be “tariffied” - that is replaced by equivalent tariffs that must then gradually be eliminated - just like everyone else’s. Tariffying terrifies our farmers.

Hang on indeed, but keep in mind that, of all Trump’s threats, this is still one of the least terrifying (tariffying?).

Tariffying - this is a superb article on where we have reached with the US-led trade war, and what might happen. My favourite quote: “We can also do stupid”.

Will Americans caught up in trade war view Trump as tariffic or tariffying?

@RonBrownstein
The GOP counts on rural/small town seats as its firewall in House. But in #TrumpTradeWar “The total value of this year’s U.S. corn, soybean and wheat crops has dropped about $13 billion, or 10%, since the start of June” WSJ reports. And more tariffs to come
