SUPPLEMENTARY INFORMATION:

Scope. —For purposes of these investigations, Commerce has defined the subject merchandise as “high purity dissolving pulp, which is a dissolving ( printed page 35269) pulp with an alpha cellulose percentage of 90 percent by weight or higher on an oven dry basis, as calculated by: alpha cellulose percentage = (100¥S10) + 0.5 * (S10¥S18) where S10 and S18 values are determined by International Organization for Standardization (ISO) 692:1982, and having a brightness level of 90 percent or higher, as measured by ISO 2470-1:2016. High purity dissolving pulp may be derived from any virgin or recycled cellulose fiber source (including, but not limited to, those sourced from hardwoods, softwoods, woody crops, agricultural crops/byproducts/residue, and agricultural/industrial/other waste). High purity dissolving pulp may be produced from a chemical pulping process including without limitation a kraft (sulfate) pulping and/or sulfite pulping process.

High purity dissolving pulp can be shipped in any form, including, but not limited to, a liquid slurry or in any dried form such as flakes, powder, granules, pellets, shreds, rolls and sheets.

The scope includes merchandise matching the above description that has been finished, packaged, or otherwise processed in a third country, including but not limited to processes such as commingling, blending, diluting, repackaging, or any other process that would not otherwise remove the merchandise from the scope of the investigation if performed in the subject country. The scope also includes high purity dissolving pulp that is commingled or blended with high purity dissolving pulp from sources not subject to this investigation. Only the subject component of such commingled or blended products is covered by the scope of this investigation.

Excluded from the scope is high purity dissolving pulp with an intrinsic viscosity under 455 milliliters per gram (mL/g), as measured by ISO 5351:2010.

Also excluded from the scope is cotton linters pulp that consists of at least 90 percent by weight, on an oven-dried basis, cotton linters fibers.”

Background. —The final phase of these investigations is being scheduled pursuant to sections 705(b) and 731(b) of the Tariff Act of 1930 (19 U.S.C. 1671d(b) and 1673d(b)), as a result of affirmative preliminary determinations by Commerce that certain benefits which constitute subsidies within the meaning of § 703 of the Act (19 U.S.C. 1671b) are being provided to manufacturers, producers, or exporters in Brazil and Norway of HPDP, and that such products are being sold in the United States at less than fair value within the meaning of § 733 of the Act (19 U.S.C. 1673b).
