2. Disputed issues and rulings

This dispute concerns the zeroing practices of the US Department of Commerce (DOC) in anti-dumping (AD) proceedings for shrimp and diamond sawblades imported from China. Based on the previous rulings on zeroing practices by the Appellate Body, China brought these disputes to the WTO dispute settlement system in order to rectify the existing AD duties.Footnote ² The panel request made on 13 October 2011 led to the panel report which was adopted on 23 July 2012. The European Union, Honduras, Japan, Korea, Thailand, and Vietnam joined as third parties in the panel proceeding.

In the AD investigation for shrimp, the US petitioners challenged exporters not only from China but also from Brazil, Ecuador, India, Thailand, and Vietnam. The dumping margins for Chinese exporters, however, were very high compared to those for other countries.Footnote ³ For example, the dumping margins for the exporters from Ecuador and Thailand were in the range of 2–4% and 5–6%, respectively. The highest dumping margins for India, Vietnam, and Brazil were about 13%, 25%, and 68%, respectively. But the major Chinese exporters were subject to AD margins which were higher than 90%, while the PRC-wide margin was determined to be 112.81%. More specific dumping margins for Chinese exporters are summarized in Table 1.

Table 1. Dumping margins for Chinese shrimp exporters

Note: A separate rate was determined for each 35 exporters/producers who were not selected for individual examination but had established their independence from the government.

In any case, Ecuador (DS335), Thailand (DS324, 343) and Vietnam (DS404, 429) also brought separate WTO disputes concerning the same US zeroing practices.Footnote ⁴

It is noted that around the time the consultation request was submitted to the WTO Dispute Settlement Body (DSB) the antidumping duties imposed on major Chinese exporters were already significantly reduced after the remand procedure. On the other hand, since China is treated as a non-market economy in the US AD investigation, India was selected as the surrogate country in this case, in consideration of India's comparable level of economic development to that of the PRC, India's significant production of frozen and canned warm-water shrimp, and the availability of India's data to value the factors of production. With respect to this shrimp AD investigation, China challenged the DOC on the use of the zeroing methodology in determining Allied, Yelin, and Red Garden's dumping margins and calculating the separate rate.

Figure 1 shows the trend of shrimp imports from the countries subject to the US AD investigations, illustrating a typical pattern for trade diversion among exporters. In the early 2000s, the imports from Thailand were dramatically replaced by the imports from China, India, and Vietnam. Then, AD actions against these exporters caused a significant negative impact on their exports to the US market. The fall in Thailand's exports relatively quickly recovered after the AD action, whereas China, India, and Brazil suffered for a longer period. However, by 2011, most of the plunges in imports from the major AD target countries generally recovered to the pre-AD period level. The recovery consequently led to the US countervailing duty actions against them in 2013.Footnote ⁵

In the AD investigation for diamond sawblades,Footnote ⁶ the DOC determined the dumping margins using zeroing methodologies for exports from ChinaFootnote ⁷ and Korea.Footnote ⁸ On 24 November 2009, Korea brought a consultation request (DS402) to the WTO DSB. On 28 February 2011, China also brought a consultation request concerning the zeroing methodology in determining the dumping margin for one of the major exporters, AT&M (Table 2).

As shown in Figure 2, the imports of diamond sawblades from China had been rapidly increasing until around the time the AD investigations were initiated. Although the imports from China dropped subsequently for a few years due to the global financial crisis, it soon picked up the general trend of rapid increase – in contrast, despite its much smaller export volume.

When China brought this case to the WTO, the United States did not oppose China's arguments that the methodology applied by the DOC in the AD investigations was ‘substantially identical in all legally relevant respects’ to the methodology employed in United States – Final Dumping Determination on Softwood Lumber from Canada (DS264). In fact, the panel explained that this case presented a similar situation with a few previous disputes such as US–Shrimp (Ecuador) (DS335) and, subsequently, US–Shrimp (Thailand) (DS343), US–Anti-Dumping Measures on PET Bags (DS383), and US–Zeroing (Korea) (DS402).

Given that the United States did not rebut the arguments and the evidence submitted by China, the panel found that the United States acted inconsistently with Article 2.4.2 of the Anti-Dumping Agreement due to the DOC's use of zeroing in the calculation of the dumping margins for Allied, Yelin, and Red Garden in the shrimp investigation, and of the dumping margin for AT&M in the diamond sawblades investigation. In addition, the panel ruled that the calculation of the separate rate on the basis of these margins necessarily incorporated the WTO-inconsistent zeroing methodology.

3. Zeroing disputes in context

Considering many previous zeroing disputes in the GATT/WTO system, this dispute does not make any additional legal contribution to the relevant jurisprudence.Footnote ⁹ And yet, this case highlights the systemic problems of the WTO dispute settlement system in terms of implementation.

Broadly speaking, zeroing disputes may be categorized into two groups: one group for setting forth important legal principles concerning zeroing practices, ‘principal cases’ and the other group for rectifying the existing illegal AD duties based on rulings of principal cases, ‘remedial cases’. Table 3 shows the zeroing disputes classified into the two categories.

Table 3. Classification of zeroing disputes

The eight disputes listed in the ‘Principal WTO Cases’ category actually illustrate unprecedented legal controversy in the WTO system regarding the zeroing practice.Footnote ¹⁰ As discussed in previous analyses, four panel decisions directly attempted to reverse the Appellate Body rulings.Footnote ¹¹ Moreover, predominant numbers of the WTO jurists, i.e., panelists and Appellate Body members, manifested the disagreement to the Appellate Body rulings. Despite all these controversies, the WTO dispute settlement system has repeatedly confirmed the illegality of zeroing practices in almost all aspects of the AD investigations.

Notwithstanding a host of the Appellate Body rulings, the fact that there are many subsequent ‘remedial’ disputes manifested structural problems in relation to the implementation of the WTO dispute settlement adjudications. Unlike other WTO Members that readily modify or change administrative actions such as by imposing AD duties pursuant to the WTO recommendations, the United States has continued to maintain its regulatory procedures to incorporate the WTO rulings.Footnote ¹²

Under Section 129 of the Uruguay Round Agreements Act that stipulates ‘Administrative Action Following WTO Panel Reports’, the US Trade Representative (USTR) must consult with the DOC along with pertinent congressional committees so as to come up with an implementation plan, and may direct the DOC to actually undertake it. In other words, implementation of an adverse WTO ruling is a two-step process. First, the USTR directs the DOC to make a new determination based on adverse WTO rulings. Second, the USTR may direct the DOC to implement the new determination.Footnote ¹³

The United States has applied this regulatory procedure stringently by interpreting that the scope of the determination can be modified very narrowly. Thus, even after the panels and the Appellate Body ruled that the zeroing practices used in an AD investigation were not consistent with the WTO obligations, the implementation of the rulings was always confined to the specific AD investigation in respective disputes. This situation caused many other WTO Members to suffer from essentially the identical problems in the US AD actions and eventually led them to bring their own complaints to the WTO dispute settlement system, separately. The 15 remedial zeroing cases listed in Table 3 are the examples of such a kind.

4. Systemic non-compliance

In an effort to implement the WTO rulings, the DOC tried to change its zeroing methodology by adopting a new rule, Antidumping Proceedings: Calculation of the Weighted Average Dumping Margin and Assessment Rate in Certain Antidumping Duty Proceedings (Proposed Modification for Reviews).Footnote ¹⁴ This new rule was finalized by the Final Modification for Reviews in February 2012.Footnote ¹⁵ The Final Modification for Reviews became effective and applicable to all reviews pending before the DOC for which the preliminary results were issued after 16 April 2012. This methodology would also be applicable to any reviews currently discontinued by the DOC if such reviews are continued after 16 April 2012 by reason of a court judgment. Pursuant to the Final Modification for Reviews, the DOC should calculate weighted-average margins of dumping and antidumping duty assessment rates without zeroing in annual administrative reviews and sunset reviews as well as in original investigations.

Although this regulatory reform resolved potential zeroing problems for AD investigations prospectively, the existing AD duties based on zeroing-laden determinations prior to the threshold timing under the Final Modification for Reviews had to be rectified pursuant to Section 129 of the Uruguay Round Agreements Act (URAA).Footnote ¹⁶ This implementation mechanism of the United States led to at least 11 ‘remedial’ cases in the WTO dispute settlement system. In fact, this whole situation raises an unprecedented problem in the GATT/WTO system especially because most of those ‘remedial’ cases were brought by developing countries.

It is actually up to a WTO Member to decide on how it will implement the rulings of a panel or the Appellate Body. As is the case with the general tenet of public international law, each WTO Member enjoys a certain amount of discretion in implementing international norms in accordance with its own legal system. In particular, countries such as the United States that adopt dualism for embracing international law obligations into their domestic legal system would mandate more rigorous and burdensome procedures to implement international judicial decisions.

The US approach to the WTO rulings on zeroing is, however, contrasted to the approach of the European Union that also declines the direct effects of the WTO rulings. After losing the EC–Bed Linen (DS141) dispute concerning zeroing practices,Footnote ¹⁷ the European Union adopted the Council Regulation (EC) No 1515/2001.Footnote ¹⁸ Article 5 of this Regulation reads:

This Regulation leaves some room for EU freedom: it uses the discretionary terms ‘may’ and ‘should’, the decision is explicitly not retroactive, and it has to be implemented through a procedure (but this procedure involves the same EU bodies as those which decide the imposition of antidumping measures, with the same threshold of simple majority). It is also worth noting that, as is often in the EU case, this Regulation does not cover safeguards. That said, it remains to be seen whether this Regulation has essentially resolved the zeroing problem in the AD investigations of the European Union.Footnote ¹⁹ Therefore, the starkly contrasted situations of the United States and the European Union in implementing the WTO rulings on zeroing practices raise a fundamental issue in the systematic compliance mechanism at a time where the WTO has lost its centrality in terms of a trade forum for quite a long time.

In such circumstances, the United States’ non-compliance on the zeroing issue is mutating from a frustrating problem into a systemic problem that is raised by a major and leading WTO Member – hence threatening the basic notion of ‘fairness’ of the WTO (Wauters, Reference Wauters2009). Such a situation raises the question of how the other WTO Members would feel entitled to react. Some proposals to amend the AD Agreement, for example in terms of monitoring, have already been tabled by ALI participants (Hoekman and Wauters, Reference Hoekman and Wauters2011; Vandenbussche, Reference Vandenbussche2009). But they have been suggested at a time where the Doha Round was expected to address this issue. As a result, because the circumstances have changed, they seem today either too far-reaching or too limited to generate in the United States (Congress) a coalition of export interests strong enough to fight and win the compliance battle in Washington.

5. Remaining Issues

After a series of WTO disputes prohibiting zeroing methods in AD investigations, the last kind of zeroing practice to be legally addressed is the zeroing method applied in a target dumping situation. The European Commission has applied the zeroing methodology in allegedly target dumping cases,Footnote ²⁰ which were repeatedly confirmed by the General Court.Footnote ²¹ In all these cases, the Commission's main argument has been the existence of ‘significant’ differences in export prices among different purchasers, regions, and time periods. But, the Commission has never defined the term ‘significant’, nor any other term such as region or period, and it has also systematically rejected the possibility to take into account the fact that such price patterns could be unintended. Combined together, these two points suggest that the zeroing method has still a bright future in the EU AD investigations. The DOC also applied target dumping concepts in recent AD investigations and calculated dumping margins based on zeroing methods. For example, in the AD investigation on ‘Bottom Mount Combination Refrigerator-Freezer’ from Korea, the DOC adopted a target dumping analysis and the zeroing method.Footnote ²² In December 2012, the DOC again applied a target dumping analysis and the zeroing method in the AD investigation on ‘Large Residential Washers’ from Korea.Footnote ²³ In this case, dumping margins were very high, 82.41% for Daewoo Electronics Corporation, 13.02% for LG Electronics, and 9.29% for Samsung Electronics. The Korean government recently indicated its intention to bring a complaint to the WTO DSB on this matter including zeroing methodology in target dumping investigations. This dispute would complete the legal gambit of zeroing practices in the WTO system. Moreover, the legal saga on zeroing practices would be one of the most significant judicial developments in the GATT/WTO jurisprudence, at least in terms of the trade remedy system.

Another issue is the diversity of trade remedy rules through the proliferation of FTAs.Footnote ²⁴ For example, Article 6.2.3(a) of the Korea–Singapore FTA stipulates that ‘when antidumping margins are established on the weighted average basis, all individual margins, whether positive or negative, should be counted toward the average’. In other words, zeroing practices are categorically prohibited for weighted average calculation methods. Considering many FTAs currently in negotiations among Asian countries that have been major targets of AD actions, it will be very likely that more Asian FTAs will adopt legal elements proposed in the Doha Round rules negotiation. On the other hand, the United States has insisted on maintaining zeroing practices at least in their markets.Footnote ²⁵ In case this kind of rule diversification among FTA partners becomes more prevalent, FTAs may aggravate trade distortions caused by such legal elements as zeroing in the trade remedy system.
