Scope text

Legally operative description of covered merchandise from the Federal Register

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 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.

Frequently asked questions

What is AD/CVD case A-570-122?

A-570-122 is a U.S. antidumping duty (AD) order on corrosion inhibitors from China, issued by the U.S. Department of Commerce. It is part of the trade-remedy regime that levies cash deposits at entry on imports found to be sold below fair value (AD) or to benefit from foreign government subsidies (CVD).

What is the deposit rate for A-570-122?

The country-wide cash deposit rate for A-570-122 is 241.02. This rate applies to importers of non-listed manufacturers/exporters from China. Individual exporters and producers may have lower (or higher) case-specific rates from Commerce administrative reviews — see the manufacturer rates linked from this page where available.

When did A-570-122 take effect, and is it still active?

A-570-122 took effect on March 19, 2021 and is currently in active status — cash deposits apply at entry on every shipment in scope.

How do I check if my shipment falls within the scope of A-570-122?

Two factors determine scope: (1) the product's HTS code(s) and physical characteristics — covered codes are listed on this page (3 flagged); and (2) the product's country of origin — this order applies to imports from China. The order's scope text — also on this page — is the legally binding description. When borderline cases arise, importers can request a formal scope ruling from Commerce. Tandom's lookup tool matches your HTS + origin against every active order in seconds.

What HTS codes are covered by A-570-122?

A-570-122 flags 3 HTS codes in Tandom's catalog. The full list is shown on this page. HTS coverage alone does not guarantee scope — physical-characteristic exclusions in the scope text may carve out specific products.

Where is the official Federal Register notice for A-570-122?

The official Federal Register citation for A-570-122 is 2021-05742. The link is on this page; clicking it opens the canonical FR document on federalregister.gov, which carries the legally operative text — scope, rates, exclusions, and effective dates.

What is the companion case for A-570-122?

A-570-122 has a companion case at C-570-123. AD orders frequently run alongside a CVD order on the same product/country (or vice versa). Both deposits stack on top of base duties — importers pay the full sum of both rates at entry where both orders apply.
