Two Trichlor Rates, and Only One Is Live

Commerce closed the 2023 countervailing review on Chinese chlorinated isocyanurates yesterday, twelve years to the day after the order itself. The number that matters is in the other case: a September preliminary that puts Heze Huayi at 90.65 percent against the 39.87 percent you are posting today. Behind the order, one of the three petitioners has stopped manufacturing and another changed owners in January.


Commerce published the final results of the 2023 countervailing duty review on chlorinated isocyanurates from China yesterday. The order being reviewed was published on November 13, 2014.

Twelve years to the day.

Heze Huayi Chemical comes out at 18.71%. Every other producer and exporter stays at 10.81%, the all-others rate from the original investigation, which Commerce says will "continue to be" the deposit rate. Cash deposits attach to entries made on or after publication, and assessment instructions go to CBP no earlier than 35 days out.

That rate already went through this desk on Friday, as one line among several. It is not why you should care about yesterday.

"If you are budgeting a 2027 trichlor buy, which of Commerce's two numbers do you use?"

Because there are two, and the one that moved is in the antidumping case.

The rest of this brief is for subscribers.

The capacity math, the trade-flow read, and what it means for the products you buy.

$50 a month, or $400 a year.
