Comprehensive Summary

Summary of Judgment

1. Introduction

This matter concerned merger proceedings before the Competition Tribunal of South Africa in relation to an intermediate merger between Senmin International (Pty) Ltd as the primary acquiring firm and Cellulose Derivatives (Pty) Ltd (CD) as the primary target firm. The Competition Commission was the respondent in the Tribunal proceedings.

The proposed transaction involved a vertical relationship: CD manufactured technical grade carboxymethylcellulose (CMC) used as a depressant in platinum mining flotation, while Senmin distributed technical grade CMC (including through vendor management services) to mining customers. The central concern was whether vertical integration would enable Senmin, post-merger, to foreclose rival downstream distributors, in particular G.M. Associates CC (GMA), which was the only other significant distributor/blender of technical grade CMC for mining in South Africa and which sourced one of its main CMC inputs from CD.

The merger was notified to the Competition Commission in October 2011. The Commission prohibited the merger in January 2012, and the Tribunal noted that the Commission had also prohibited the same merger in 2009, without the merging parties then pursuing Tribunal consideration. Following the 2012 prohibition, the merging parties requested the Tribunal to consider the proposed merger in terms of section 16(1)(a) of the Competition Act 89 of 1998. The Tribunal heard evidence in July and September 2012 and received final written submissions on conditions by 31 October 2012.

On 8 November 2012, the Tribunal conditionally approved the merger. These reasons (issued on 7 February 2013) explained why the Tribunal concluded that the merger was likely to substantially prevent or lessen competition absent conditions, but that the identified harm could be addressed through behavioural supply and pricing conditions imposed on the merged entity.

The general subject-matter of the dispute concerned vertical foreclosure in the supply chain for technical grade CMC used in mining flotation, including whether imported CMC constituted a sufficient competitive constraint and whether downstream CMC products were meaningfully differentiated so as to limit diversion from a foreclosed distributor to the merged entity.

2. Material Facts

Senmin was a wholly-owned subsidiary within the AECI group and operated, among other activities, as a distributor of specialised mining chemicals. Of particular relevance, Senmin distributed technical grade CMC to platinum mining customers in South Africa, marketing three CMC products (Sendep 30D, Sendep 30E and Sendep 30F) that were manufactured exclusively for Senmin by CD using Senmin’s proprietary knowhow. Senmin also provided vendor management services (VMS) to mining customers, under which it supplied chemicals and associated services (and, on the evidence, equipment for storage and mixing at certain concentrator plants).

CD, controlled by the Shannon Trust, was found to be the only producer in South Africa of technical grade CMC. It produced multiple grades of technical grade CMC and supplied two operating production lines: one line supplying Senmin and another supplying GMA. Besides Senmin, GMA was the only other significant distributor/blender supplying technical grade CMC products to the mining industry in South Africa. ChemQuest and Protea Mining supplied CMC to mines but were found to source their CMC products from GMA and to on-sell them; they did not independently tailor CMC products.

The transaction, in terms of a sale of business agreement, entailed Senmin acquiring CD’s technical grade CMC manufacturing business as a going concern, resulting in Senmin obtaining sole control of CD. Senmin’s stated rationale included securing supply of CMC and avoiding disclosure of knowhow to actual or potential competitors, together with the ability to further develop CMC technology and potentially expand production capacity. The seller’s rationale was to realise value.

On public interest, the Tribunal recorded that the transaction raised no public interest concerns, including no anticipated negative effect on employment in South Africa and no envisaged retrenchments.

The Tribunal delineated the upstream market as the manufacture and supply of technical grade CMC for use in mining, excluding guar (found not to be a real substitute for most mines) and excluding pure grade CMC (imported and generally too costly for local mining use). The downstream market was delineated as the distribution of CMC for use in flotation in mining, and its geographic scope was treated as national.

A substantial factual dispute concerned whether CMC imports could serve as an effective substitute and constraint. The Tribunal accepted evidence that import statistics did not allow a reliable distinction between pure and technical grade CMC, and it accepted that while CMC was imported into South Africa for other uses (notably food and detergents), there was no credible evidence that imported CMC offered a feasible alternative (in terms of both quality/performance and competitive price) for mining flotation use in South Africa. GMA imported CMC from Lamberti, but the Tribunal accepted GMA’s evidence that imported CMC was used in blends and could not replace CD’s locally supplied CMC as the base for most of GMA’s range of mining products. The Tribunal also accepted evidence of past investigations by GMA into import alternatives, including quality-performance failures and/or uncompetitive landed cost outcomes, and it treated these as relevant given the evidence that GMA had been threatened with supply interruptions by CD during the period when the merger was being considered.

Another disputed issue concerned downstream substitutability and differentiation between Senmin’s and GMA’s CMC offerings. The Tribunal accepted that mining customers’ primary concern in selecting depressants was recovery performance, with price as a secondary metric where products performed similarly. The only mining customer witness, Lonmin’s representative, testified that Senmin’s Sendep 30F and a GMA product were substitutable for Lonmin (with testing showing no real difference in recovery), and rejected the suggestion that the products were significantly differentiated and not substitutable. The Tribunal also treated price comparisons between Senmin and GMA as inconclusive because Senmin’s pricing was intertwined with its VMS offering, including equipment and services that GMA did not provide.

The Tribunal treated as material the evidence that switching to an untested reagent would require extensive testing, with a process potentially taking up to a year, and that mines were highly sensitive to any disruption in reagent supply because interruptions to production were unacceptable. This was linked to the Tribunal’s assessment of the likely effects of foreclosure and customers’ responses.

3. Legal Issues

The central legal question was whether the proposed vertical merger was likely to substantially prevent or lessen competition through input foreclosure in the downstream market for distribution of CMC-based depressants to mining customers, particularly by enabling the merged entity to foreclose or raise the costs of GMA.

The Tribunal framed the competitive harm principally as involving the application of competition-law principles to contested economic and factual questions, including market definition and competitive constraint, the practical feasibility of import substitution, and the extent of rivalry and substitution between the downstream offerings of Senmin and GMA. The assessment also required an evaluative judgment about the merged entity’s ability and incentive to engage in foreclosure, and about whether behavioural conditions would adequately address the merger-specific harm.

Although the Commission advanced additional theories, the Tribunal expressly stated it would not decide the Commission’s “leveraging” theory concerning VMS minimum purchase requirements and bundling into adjacent flocculent markets, and it likewise did not decide an additional theory of harm relating to foreclosure in adjacent frothers markets due to insufficient substantiation. The Tribunal confined its analysis to the merger-specific concern of downstream foreclosure in relation to CMC distribution.

4. Court’s Reasoning

The Tribunal approached the matter by first identifying the vertical structure of the supply chain and the relevant markets. It accepted that the relevant upstream product market was the manufacture and supply of technical grade CMC for mining, excluding guar and pure grade CMC as substitutes. It then focused on the degree of concentration and the availability of competitive constraints in both upstream production and downstream distribution.

In assessing upstream constraints, the Tribunal placed weight on the finding that CD was the only domestic producer of technical grade CMC and that new entry into domestic production was highly unlikely, given the size of the market and existing capacity. The Tribunal considered whether imported CMC should expand the geographic market and constrain domestic supply. It rejected that proposition on the evidence before it, concluding that there was no credible evidence that imported technical grade CMC suitable for mining flotation could be obtained at an acceptable quality and at a competitive price (once duties, transport, and inventory costs were considered), and that any purported import alternatives had not been tested for performance. While recognising that imports might place a longer-term ceiling on price increases, the Tribunal did not accept imports as a meaningful post-merger constraint for the foreclosure analysis.

On the downstream side, the Tribunal treated distribution as the relevant level because mining customers did not procure CMC directly from international manufacturers and relied on local distributors that provided intermediary services including adaptation, testing, and dosing support. It accepted that effective competition in distribution was, for practical purposes, between Senmin and GMA, given that other suppliers (ChemQuest and Protea) sourced from GMA and did not tailor products independently.

A major point in dispute was whether Senmin’s and GMA’s products and services were so differentiated that they did not materially constrain each other. The Tribunal treated the perspective of mining customers as central and regarded recovery as the key variable driving demand. It relied heavily on Lonmin’s evidence as the only customer testimony. That evidence supported substitutability between Senmin’s and GMA’s products for at least certain applications, and it did not support Senmin’s assertion that its products were inherently superior in performance. The Tribunal therefore did not accept that differentiation was sufficient to neutralise competitive rivalry between the two distributors.

The Tribunal also assessed evidence of price differences between the distributors and found it not determinative of substitution. It accepted that Senmin’s VMS arrangements could embed equipment and service costs into pricing, making direct comparisons with GMA’s pricing misleading. It further accepted that differences in dosing and wastage reduction under VMS complicated a mine’s total cost assessment. Even so, the Tribunal concluded that mines regarded Senmin and GMA as alternative suppliers and that a reduction in alternatives would weaken customers’ bargaining position.

Having found upstream monopoly production, high downstream concentration, limited viable import constraint, and meaningful downstream substitution, the Tribunal evaluated the merged entity’s ability and incentive to foreclose. It accepted that CD’s supply to GMA was a significant input for GMA’s product range and that replacing it with imports would be difficult and slow due to performance testing requirements and inventory/security-of-supply considerations. Given mines’ intolerance for supply disruptions and long testing cycles for new reagents, the Tribunal reasoned that even partial foreclosure or uncertainty about a rival’s security of supply could lead mines to shift to the merged entity as the only locally secure integrated supplier.

In assessing whether foreclosure would be profitable and attractive, the Tribunal considered but did not find decisive the economic experts’ diversion modelling. It preferred the factual evidence regarding customer behaviour, switching constraints, and security-of-supply requirements. It reasoned that, given the market characteristics and the ability of the merged entity to adapt products and innovate to meet customer needs, diversion to the merged entity was likely in a foreclosure scenario. The Tribunal concluded that the merged entity would have both the ability and incentive to foreclose downstream rivals, thereby reducing competitive choice, weakening customer bargaining, and potentially reducing competitive pressure to improve product performance and innovation over time.

The Tribunal then considered remedies. It recorded that the merging parties tendered behavioural conditions to address foreclosure concerns, that the Commission regarded them as inadequate in their original form, and that after Tribunal-directed engagement and submissions, the parties accepted several enhancements. The Tribunal imposed the final amended behavioural conditions and added an additional monitoring condition relating to the Commission’s ability to verify compliance with the pricing provisions.

The Tribunal concluded that the conditions were adequately tailored and proportionate to maintain effective downstream rivalry by ensuring continued supply to GMA on specified terms, thereby addressing the merger-specific input foreclosure concern.

5. Outcome and Relief

The Tribunal conditionally approved the intermediate merger between Senmin and CD, subject to a set of behavioural conditions reflected in “Annexure A”.

The conditions required the merged entity to supply GMA with an annual minimum quantity of CMC at equivalent quality and specifications to that previously supplied, and imposed a pricing formula to calculate the maximum supply price. The conditions also provided for non-discriminatory supply to other customers in specified circumstances, mechanisms for independent verification of cost increases associated with price increases, provisions governing volume adjustments and supply disruptions (including verification), ongoing testing to maintain product specifications, and reporting and monitoring obligations. The Tribunal additionally imposed a condition to enable effective monitoring of compliance with the pricing provisions.

No order as to costs was recorded in the reasons.

Held

The Tribunal held that the proposed transaction, assessed as a vertical merger, was likely to substantially prevent or lessen competition in the relevant market(s) because the merged entity would have both the ability and incentive to foreclose downstream rivals in the distribution of technical grade CMC for mining flotation, particularly GMA, through refusal to supply and/or raising rivals’ costs.

The Tribunal further held that the identified competitive harm would, however, be adequately remedied by imposing behavioural conditions designed to preserve downstream competition by ensuring continued supply to GMA on specified quality, quantity, and price terms, together with monitoring and verification measures.

LEGAL PRINCIPLES

The Tribunal applied the principle that a vertical merger can harm competition where the merged firm gains control of an important upstream input and can engage in input foreclosure by refusing supply or raising rivals’ costs in a downstream market. The assessment requires an evaluative inquiry into both the ability to foreclose (including upstream market power and the availability of alternatives such as imports) and the incentive to foreclose (including the likelihood of diversion to the merged entity and market characteristics affecting profitability).

In evaluating whether alternatives constrain foreclosure, the Tribunal applied the principle that putative supply alternatives (including imports) must be credible not only in theory but in practice, considering quality/performance suitability, landed cost competitiveness, and the practicalities of switching, including customer testing requirements and security-of-supply considerations. Where products are performance-sensitive and customer qualification/testing is lengthy, the Tribunal treated switching as slow and disruptive, affecting the competitive constraint posed by alternative suppliers.

The Tribunal also applied the principle that claims of downstream product differentiation must be assessed with reference to customer evidence and behaviour in the relevant setting, particularly where product performance (here, recovery in mining flotation) is decisive and price comparisons may be confounded by bundled services and equipment.

Finally, the Tribunal applied the principle that where a merger is likely to substantially lessen competition, it may nonetheless be approved subject to conditions that are targeted, proportionate, and capable of monitoring and enforcement, including mechanisms to maintain supply, constrain pricing, and verify compliance through independent auditing and reporting.
