SUPPLEMENTARY INFORMATION:

Background

On March 19, 2021, Commerce published in the Federal Register the Orders on certain corrosion inhibitors from the People's Republic of China.^[1] On February 2, 2026, the ITC instituted,^[2] and Commerce initiated,^[3] the first sunset review of the Orders, pursuant to section 751(c) of the Tariff Act of 1930, as amended (the Act). As a result of its reviews, Commerce determined that revocation of the Orders would likely lead to the continuation or recurrence of dumping and countervailable subsidies, and therefore, notified the ITC of the magnitude of the margins of dumping and subsidy rates likely to prevail should the Order be revoked.^[4]

On August 4, 2026, the ITC published its determination, pursuant to sections 751(c) and 752(a) of the Act, that revocation of the Orders would likely lead to continuation or recurrence of material injury to an industry in the United States within a reasonably foreseeable time.^[5]

Scope of the Orders

The merchandise covered by these Orders is tolyltriazole and benzotriazole. This includes tolyltriazole and benzotriazole of all grades and forms, including their sodium salt forms. Tolyltriazole is technically known as Tolyltriazole IUPAC 4,5 methyl benzotriazole. It can also be identified as 4,5 methyl benzotriazole, tolutriazole, TTA, and TTZ.

Benzotriazole is technically known as IUPAC 1,2,3-Benzotriazole. It can also be identified as 1,2,3-Benzotriazole, 1,2-Aminozophenylene, lH-Benzotriazole, and BTA.

All forms of tolyltriazole and benzotriazole, including but not limited to flakes, granules, pellets, prills, needles, powder, or liquids, are included within the scope of these orders.

The scope includes tolyltriazole/sodium tolyltriazole and benzotriazole/sodium benzotriazole that are combined or mixed with other products. For such combined products, only the tolyltriazole/sodium tolyltriazole and benzotriazole/sodium benzotriazole component is covered by the scope of these Orders. Tolyltriazole and sodium tolyltriazole that have been combined ( printed page 50759) with other products is included within the scope, regardless of whether the combining occurs in third countries. Tolyltriazole, sodium tolyltriazole, benzotriazole and sodium benzotriazole that is otherwise subject to these Orders is not excluded when commingled with tolyltriazole, sodium tolyltriazole, benzotriazole, or sodium benzotriazole from sources not subject to these Orders. Only the subject merchandise component of such commingled products is covered by the scope of these Orders.

A combination or mixture is excluded from these Orders if the total tolyltriazole or benzotriazole component of the combination or mixture (regardless of the source or sources) comprises less than 5 percent of the combination or mixture, on a dry weight basis.

Notwithstanding the foregoing language, a tolyltriazole or benzotriazole combination or mixture that is transformed through a chemical reaction into another product, such that, for example, the tolyltriazole or benzotriazole can no longer be separated from the other products through a distillation or other process is excluded from these orders. Tolyltriazole has the Chemical Abstracts Service (CAS) registry number 299385-43-1. Tolyltriazole is classified under Harmonized Tariff Schedule of the United States (HTSUS) subheading 2933.99.8220. Sodium Tolyltriazole has the CAS registry number 64665-57-2 and is classified under HTSUS subheading 2933.99.8290. Benzotriazole has the CAS registry number 95-14-7 and is classified under HTSUS subheading 2933.99.8210. Sodium Benzotriazole has the CAS registry number 15217-42-2. Sodium Benzotriazole is classified under HTSUS subheading 2933.99.8290. Although the HTSUS subheadings and CAS registry numbers are provided for convenience and customs purposes, the written description of the scope of these Orders is dispositive.

Continuation of the Orders

As a result of the determinations by Commerce and the ITC that revocation of the Orders would likely lead to continuation or recurrence of dumping, countervailable subsidies, and material injury to an industry in the United States, pursuant to section 751(d)(2) of the Act, Commerce hereby orders the continuation of the Orders. U.S. Customs and Border Protection will continue to collect AD and CVD cash deposits at the rates in effect at the time of entry for all imports of subject merchandise.

The effective date of the continuation of the Orders will be August 4, 2026.^[6] Pursuant to section 751(c)(2) of the Act and 19 CFR 351.218(c)(2), Commerce intends to initiate the next five-year reviews of the Orders not later than 30 days prior to fifth anniversary of the date of the last determination by the ITC.
