Start Preamble
AGENCY:
Office of the United States Trade Representative.
ACTION:
Notice of determinations and action; notice of proposed action; request for written comments; invitation to participate in public hearing.
SUMMARY:
The United States Trade Representative (Trade Representative), pursuant to sections 304(a)(1)(A) and 301(b) of the Trade Act of 1974, as amended (the Trade Act), has determined that certain acts, policies, and practices of Ukraine with respect to the protection of intellectual property rights are unreasonable and burden or restrict United States commerce and are thus actionable under section 301(b). Pursuant to sections 304(a)(1)(B), 301(b) and 301(c) of the Trade Act, the Trade Representative has determined that appropriate action to obtain the elimination of such acts, policies, and practices includes the suspension of duty-free treatment accorded to all products of Ukraine under the Generalized System of Preferences (GSP) program. Moreover, because further action may include the imposition of prohibitive duties on certain products of Ukraine, in this notice USTR is also publishing a preliminary list of Ukrainian products under consideration for the imposition of prohibitive duties. USTR invites interested persons to submit written comments and to participate in a public hearing concerning the possible imposition of prohibitive duties on the products on the enclosed preliminary list.
EFFECTIVE DATES:
The Trade Representative's determinations as to actionability under section 301(b) and the suspension of GSP benefits were made on August 2, 2001. The suspension of Ukraine's GSP benefits will be effective with respect to goods entered, or withdrawn from warehouse, for consumption on or after August 24, 2001. With respect to the preliminary list of Ukrainian products under consideration for the imposition of prohibitive duties: requests to appear at the public hearing are due by August 24, 2001; written testimony is due by August 31, 2001; a public hearing is scheduled for September 11, 2001; and written comments and rebuttal comments are due by September 17, 2001.
ADDRESSES:
Requests, comments, and testimony should be submitted to Sybia Harrison, Staff Assistant to the Section 301 Committee, ATTN: Docket 301-121, Office of the United States Trade Representative, 1724 F Street, NW., Room 217, Washington, DC 20508. The public hearing is scheduled to be held in at the Office of the United States Trade Representative, 1724 F Street, NW., Rooms 1 and 2, Washington, DC.

End Further Info End Preamble Start Supplemental InformationSUPPLEMENTARY INFORMATION:
In a notice published on April 6, 2001 (66 FR 18346), USTR announced the initiation of a section 302 investigation regarding the Government of Ukraine's intellectual property protection laws and practices, including the Government of Ukraine's failure to use existing law enforcement authority to stop the ongoing unauthorized production of optical media products and to enact an optical media licensing regime that would preclude the piracy of such products. See 66 FR 18346 (April 6, 2001). The April 6, 2001 notice proposed to determine that these acts, policies and practices are actionable under section 301(b) and that appropriate action may include the suspension of duty-free treatment accorded under the GSP program to some or all products of Ukraine. The notice also stated that, as a further step, the Trade Representative might decide to impose increased duties or other import restrictions on Ukrainian goods. Finally, the April 6, 2001 notice stated that prior to imposing increased duties or import restrictions on Ukrainian goods, USTR would publish a notice requesting comments on a specific list of Ukrainian products.Start Printed Page 42247
The Section 301 Committee conducted a public hearing on April 27, 2001, and received and reviewed written comments on the issues in the investigation. As of this time, the Government of Ukraine has not stopped the unauthorized production of optical media products and has not enacted a licensing regime to prevent optical media piracy.
Determinations
Matters actionable under section 301(b) include acts, policies, or practices of a foreign government that are “unreasonable” and burden or restrict U.S. commerce. Under section 301(d)(3)(B)(i)(II), “unreasonable” practices include any act, policy or practice which denies fair and equitable provision of adequate and effective protection of intellectual property rights.
The United States has consulted repeatedly with the Government of Ukraine regarding the matters under investigation. The Government of Ukraine has made very little progress in addressing two key issues: (1) the use of existing law enforcement tools to stop the current piracy, and (2) the introduction of an optical media licensing regime (which has become the international norm) to prevent a subsequent resurgence of pirate activity. Accordingly, on the basis of the investigation initiated under section 302 of the Trade Act, the comments received, and the consultations, the Trade Representative has determined pursuant to sections 301(b) and 304(a)(1)(A) of the Trade Act that the acts, policies and practices of Ukraine with respect to the protection of intellectual policy rights are unreasonable and burden or restrict U.S. commerce, and are thus actionable under section 301(b).
Because the determination of the Trade Representative under section 304(a)(1)(A) of the Trade Act is affirmative, the Trade Representative must determine the appropriate and feasible action to take under section 301(b) and (c). In a case in which the act, policy, or practice under investigation also fails to meet the eligibility criteria for receiving duty-free treatment under the GSP program, section 301(c)(1)(C) of the Trade Act provides that the Trade Representative may withdraw, limit or suspend such duty-free treatment. One of the GSP program's eligibility criteria is the extent to which a foreign country provides adequate and effective protection of intellectual property rights.
Pursuant to sections 304(a)(1)(B), 301(b), and 301(c)(1)(C) of the Trade Act, the Trade Representative has determined that appropriate and feasible action includes the suspension of duty-free treatment accorded to the products of Ukraine under the GSP program. Accordingly, the Harmonized Tariff Schedule of the United States (HTS) is modified as follows: (1) General note 4(a) is modified by deleting “Ukraine” from the list of independent countries; (2) general note 4(d) is modified by deleting “2306.30.00 Ukraine” and by deleting “Ukraine” set out opposite subheading 2804.29.00; and (3) the Rates of Duty 1-Special subcolumn for HTS subheading 2306.30.00 is modified by deleting the “A*” and inserting an “A”. The foregoing modifications to the HTS are effective with respect to articles entered, or withdrawn from warehouse, for consumption on or after August 24, 2001.
Also, in this notice USTR is proposing that further action under section 301—in addition to the suspension of GSP benefits—if appropriate should include the imposition of prohibitive duties on a final list of Ukrainian products. The final list of products would be drawn from the attached preliminary list.
Written Comments and Public Hearing
The Section 301 Committee invites interested persons to submit written comments and to participate in a public hearing on the possible imposition of prohibitive duties on the products of Ukraine identified in the preliminary product list in the Annex to this notice. The comments sought by the Section 301 Committee with respect to particular products include (i) whether imposing prohibitive duties on a particular product would be practicable or effective in terms of obtaining an elimination of the acts, policies, and practices of the Government of Ukraine that are the subject of the investigation; and (ii) whether imposing prohibitive duties on a particular product would cause disproportionate economic harm to U.S. interests, including small- or medium-size businesses.
In the annexed products list, the items with respect to which comments are requested are products of Ukraine classified in the indicated subheadings of the HTS. The product descriptions in the annex are for information purposes only; the descriptions are not intended to delimit in any way the scope of products that are under consideration for the imposition of increased duties. Instead, the scope of the proposed action under section 301 is governed by the HTS nomenclature for the subheadings listed in the annex. Issues regarding the classification of particular products would be decided by the U.S. Customs Service under its usual rules and procedures for product classification.
Written comments are due by September 17, 2001. A public hearing addressed to these same issues is scheduled for September 11, 2001, in Rooms 1 and 2, First Floor, Office of the United States Trade Representative, 1724 F Street, NW., Washington, DC. Interested persons wishing to testify orally at the hearing must provide a written request by August 24, 2001 to Sybia Harrison, Staff Assistant to the Section 301 Committee, ATTN: Docket 301-121, Office of the United States Trade Representative, 1724 F Street, NW., Room 217, Washington, DC 20508. Requests to testify must include the following information: (1) Name, address, telephone number, fax number, and firm or affiliation of the person wishing to testify; and (2) a brief summary of the comments to be presented. After the Chairman of the Section 301 Committee considers the request to present oral testimony, Ms. Harrison will notify the applicant of the time of his or her testimony. In addition, persons presenting oral testimony must submit their complete written testimony by August 31, 2001. In order to allow each interested party an opportunity to contest the information provided by other parties at the hearing, USTR will accept written rebuttal comments, which must be filed by September 17, 2001. Rebuttal comments should be limited to demonstrating errors of fact or analysis not pointed out in the hearing and should be as concise as possible. All written comments must state clearly the position taken, describe with particularity the supporting rationale, be in English, and be provided in twenty copies to: Sybia Harrison, Staff Assistant to the Section 301 Committee, ATTN: Docket 301-121, Office of the United States Trade Representative, 1724 F Street, NW., Room 217, Washington, DC 20508. In addition, all written comments should list on the first page the particular HTS subheadings which are addressed in the comments.
Comments will be placed in a file (Docket 301-121) open to public inspection pursuant to 15 CFR 2006.13, except confidential business information exempt from public inspection in accordance with 15 CFR 2006.15.
