1. On 04/24/2019, Commerce published in the Federal Register its initiation of the antidumping duty investigation of sodium sulfate anhydrous from Canada (84 FR 17138). The effective date of this initiation is 04/17/2019 (the applicable date stated in the FR notice).

2. The scope of this investigation covers sodium sulfate (Na2SO4) (Chemical Abstracts Service (CAS) Number 7757-82-6) that is anhydrous (i.e., containing no water), regardless of purity, grade, color, production method, and form of packaging, in which the percentage of particles between 20 mesh and 100 mesh, based on U.S. mesh series screens, ranges from 10-95% and the percentage of particles finer than 100 mesh, based on U.S. mesh series screens, ranges from 5-90%.

Excluded from the scope of this investigation are specialty sodium sulfate anhydrous products, which are products whose particle distributions fall outside the described ranges. Glauber's salt (Na2SO4·10H2O), also known as sodium sulfate decahydrate, an intermediate product in the production of sodium sulfate anhydrous that has no known commercial uses, is not included within the scope of the investigation, although some end-users may mistakenly refer to sodium sulfate anhydrous as Glauber's salt. Other forms of sodium sulfate that are hydrous (i.e., containing water) are also excluded from the scope of the investigation.

The merchandise subject to this investigation is classifiable under Harmonized Tariff Schedule of the United States (HTSUS) subheading 2833.11.5010. Subject merchandise may also be classified under 2833.11.1000, 2833.11.5050, and 2833.19.0000. Although the HTSUS subheadings and CAS registry number are provided for convenience and customs purposes, the written description of the scope of the investigation is dispositive.

3. This proceeding has been assigned case number A-122-866.
