Scope text

Legally operative description of covered merchandise from the Federal Register

The products covered by these orders are alkyl phosphate esters, which are halogenated and non-halogenated phosphorus-based esters with a phosphorus content of at least 6.5 percent (per weight) and a viscosity between 1 and 2000 mPa·s (at 20-25 °C). Merchandise subject to these orders primarily includes tris (2-chloroisopropyl) phosphate (TCPP), tris (1,3-dichloroisopropyl) phosphate (TDCP), and triethyl phosphate (TEP)). TCPP is also known as tris (1-chloro-2- propyl) phosphate, tris (1-chloropropan-2-yl) phosphate, tris (monochloroisopropyl) phosphate (TMCP), and tris (2-chloroisopropyl) phosphate (TCIP). TCPP has the chemical formula C9H18Cl3O4P and the Chemical Abstracts Service (CAS) Nos. 1244733-77-4 and 13674-84-5. It may also be identified as CAS No. 6145-73-9. TDCP is also known as tris (1,3-dichloroisopropyl) phosphate, tris (1,3-dichloro-2-propyl) phosphate, chlorinated tris, tris {2- chloro-1-(chloromethyl ethyl){time} phosphate, TDCPP, and TDCIPP. TDCP has the chemical formula C9H15Cl6O4P and the CAS No. 13674-87-8. TEP is also known as phosphoric acid triethyl ester, phosphoric ester, flame retardant TEP, tris(ethyl) phosphate, triethoxyphosphine oxide, and ethyl phosphate (neutral). TEP has the chemical formula (C2H5O)3PO and the CAS No. 78-40-0. Imported alkyl phosphate esters are not excluded from the scope of these orders even if the imported alkyl phosphate ester consists of a single isomer or combination of isomers in proportions different from the isomers ordinarily provided in the market. Also included in these orders are blends including one or more alkyl phosphate esters, with or without other substances, where the alkyl phosphate esters account for 20 percent or more of the blend by weight.

Frequently asked questions

What is AD/CVD case A-570-168?

A-570-168 is a U.S. antidumping duty (AD) order on alkyl phosphate esters 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-570-168?

The country-wide cash deposit rate for A-570-168 is 243.09%. 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-570-168 take effect, and is it still active?

A-570-168 took effect on June 11, 2025 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-570-168?

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-570-168?

A-570-168 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-570-168?

The official Federal Register citation for A-570-168 is 2025-10630. 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-570-168?

A-570-168 has a companion case at C-570-169. 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.
