This paper considers the capability of the world processing tomato industry to expand tomato paste production without requiring substantial new capital investment. It responds to concerns about a return to the depressing oversupply conditions of the last few years. We conclude that such a danger exists because there is a current global overcapacity of 5 million metric tons of raw product beyond 1993 input levels. Attempts to utilize this capacity, without a corresponding increase in consumer demand, would depress paste prices once again below profitable levels. Our analysis focuses on supply side issues only, and not on potential demand changes.

Worldwide Processing Tomato Production by Country

The U.S. Foreign Agricultural Service (FAS) estimates that 1993 production of tomatoes for processing in major producing countries will reach 16.6 million tons (all figures metric unless noted). The list of countries omits other producers of significance including Canada, Argentina, Brazil, Chile, Australia, Russia, China, and other former Eastern bloc countries, many of whom are not active in global trade. We believe that these added countries will require an added 8 million tons of tomatoes for processing.

Principal producers for the world market in the FAS list are projected to be the United States, 8.9 million tons; Italy, 3.4 million tons; Turkey, 1.1 million tons; Greece, 1.0 million tons; and Spain, 0.8 million tons. Other significant producers are expected to be Portugal, 0.4 million tons; Mexico, 0.4 million tons; Israel, 0.2 million tons; and Taiwan, 0.1 million tons.

Practices differ from country to country as to what proportion of the total tomato crop is allocated to processing. The share tends to be large in the United States and Canada, and relatively low in important fresh-market producing countries such as Spain and Turkey. For the period 1988-90, the share of the total tomato crop grown or diverted for processing in OECD countries was 61.0%. Among the member countries, however, percentages for principal tomato producers varied widely: Netherlands, 0.0%; Turkey, 30.4%; Spain, 31.4%; Japan, 34.8%; France, 40.5%; EC-12, 53.1%; Portugal, 64.4%; Greece, 65.4%; Italy, 71.7%; United States, 83.8%; Canada, 84.9%. In the U.S., from 55 to about 60% of processing tomatoes are used for paste, with the rest going into canned tomatoes, sauce, juice, and other processed products.

Tomato Production and Processing

Some substantial increases in tomato processing and trade occurred between 1987 and 1992 in the principal producing countries (Table 1). The volume of tomatoes used by processors increased by 1.7 million tons (11.5%), the production of paste expanded by 307,000 tons (21.0%), and paste exports of the selected countries grew by 141,000 tons (20.3%). The growth in paste production and trade appears moderate, averaging only 4% per year. But the appearance is deceptive because within the period, all three categories rose even higher before declining to their 1992 level. In particular, processing tomato production exceeded 18 million tons during each of the three years from 1989 to 1991, with a peak in 1990 of nearly 19 million tons, 3 to 5 million tons greater than the levels in either 1987 or 1992. This built up the enormous supplies that contributed to the price crash following 1989, when California f.o.b. prices plummeted from 60 cents per pound to 27 cents in a period of 3 years. It is interesting to note, however, that despite the dominant size of the U.S. paste industry, it only accounted for about one-third of the growth in paste production between 1987 and 1992. Turkey accounted for 29 percent of this growth and Italy for 26 percent.

Production results varied between countries. Processing tomato production increased significantly in the United States, 1 million tons (15%); Turkey, 0.6 million tons (67%); less so in Greece, 0.1 million tons (14%), and Canada, 0.1 million tons (22%). Increases were marginal in most other countries except for Israel, Taiwan, and Mexico, where production declined. As for tomato paste, the United States increased production by around 105,000 tons (16%), Turkey by 90,000 tons (+64%), Italy by 81,000 tons (+37%), and Spain by 38,000 tons (+66%). Much of the production was for export markets: United States exports were up by 64,000 tons, Turkey by 53,000 tons, and Spain by 27,000 tons.

Countries also vary in the solids content of tomatoes used for making paste and in the efficiency with which the process takes place. This is reflected in the conversion rates applying to the major countries (Table 2).

Where no specific conversion rate is available, OECD uses a general baseline rate of 6.2:1. The California Tomato Growers Association uses a conversion rate of 5.86:1 for 31 brix paste, which assumes 98% plant efficiency. This is equivalent to a conversion ratio of 5.4:1 for 28-30 brix paste without loss, the standard used for other estimates in Table 2. The major inference from Table 2 is that the newer-producing countries such as Brazil, Argentina and Mexico, and to a lesser extent Turkey, have room to improve the quality of their processing tomatoes.

Pricing Cycles: the Relationship Between Grower and Paste Prices

The profits available to processors are important in explaining industry expansion. In the absence of information on industry profits, we have analyzed the gross margin available to processors, that is, the difference between what they pay for tomatoes and what they receive for paste. This analysis shows that margins have been highly variable, in fact more variable than either paste or grower prices (Figure 1a). But they were also profitable for much of the period relative to the margin needed for a modern paste specialty plant. The estimated margins averaged at or above 20 cents per pound ($441 per ton) in all years between 1980 and 1990 in California except in 1985 when they were about 19 cents per pound. Such margins are adequate to cover at least full costs of processing in a modern plant. They become inadequate, depending on plant characteristics, as they go below 20 cents per pound, as they did in 1991 and 1992. Margins are expected to be more profitable in 1993.

 

Figure 1a. Tomato Paste: Delivered Tomato Prices and Processor Gross Margins,
California, 1980-1993.



When grower prices are converted to a price for the quantity of tomatoes needed to make one pound of paste, they show a remarkable stability relative to paste prices (Figure 1b). The paste price is the California wholesale price for bulk industrial tomato paste, for July or other month as noted. The grower price has been converted from dollars per ton to cents per 5.86 lbs.&emdash;the average quantity of fresh tomatoes required to produce one pound of tomato paste (30-32 Brix) in California, including losses. These data are not precise, since the paste price is for one month only, but they are adequate indicators of the differences in price volatility.

United States, 1980-1993.



We find little evidence of a lagged correlation between the grower and processor price cycles. Thus, we find no way of projecting what grower or processor prices will be in the future based on knowledge of what they are today. In 9 out of the 13 years observed, grower and processor prices moved in the same direction, and in 4 years, they moved in opposite directions, but very weakly. The more important phenomenon is the relative stability in grower prices.

This stability in California arises primarily because of the way the market for processing tomatoes is structured. Essentially, price is determined through bargaining between individual processors and the California Tomato Growers Association, representing a substantial majority of growers selling to about 25 proprietary processors. This process establishes price and other parameters for contracts which are subsequently negotiated between individual processors and growers. The bargaining is intense because processors still control the amount that they will buy and can choose, in many cases, to import paste. This type of market structure favors stable prices for sellers (growers) and places almost all finished product price risks with the buyers (processors).

The processors' market for finished tomato paste is more diverse than that of growers for raw tomatoes. The tomato product market consists of a wide array of remanufacturers, domestic food services, and other wholesale and retail customers, buying both through contracts and at spot prices. Internationally, this product market is further served by export trade with Canada and East Asia, and by imports from Mexico, Chile, and other countries. This market is more competitive than that for raw tomatoes because of relatively larger numbers of buyers and sellers. In consequence, paste prices (Chart 1) display more volatility than raw tomato prices: higher peaks, lower troughs, and a possibly greater frequency of each. A similar relationship occurs in the EC where minimum grower prices, established politically, tend to be much more stable than paste prices.

The coefficient of variation measures the relationship between average prices and their variability. A high value indicates greater variability than a low value. Applying this measure to California prices shows that the coefficient for raw tomatoes is 6.5%, an indicator of stable prices, and the coefficient for paste is 21.0%, suggesting that paste prices are 3.25 times more volatile. The coefficient for processor margins is over 50% higher than for paste prices, indicating the high degree of uncertainty about margins. These measures support the conclusion that processors are unsuccessful in shifting their price risks back to growers in the short term.

Industry Structure and Capacity Estimates by Country

We estimate that global full-season engineered capacity for producing tomato paste is 25.2 million tons of raw product, or approximately 4.2 million tons of paste (Table 3). This estimate is for capacity in principal producing countries and is calculated as the 3-shift daily capacity times the average number of days per season. Where data permits, we have estimated plant numbers and their distribution by size and average production per plant. This suggests that there are approximately 635 paste-producing plants in the principal producing countries, and that the median engineered capacity of these plants is less than 30,000 tons of tomatoes per season.

Capacity estimates in the table are those available, derived, or otherwise calculated from Amitom, USDA-FAS, EC, and our own data on the various paste-producing countries. The various estimation approaches as well as problems with these approaches are explained below.

The capacity estimate for Greece was derived from information about the EC production quota allocated to Greece, and the relationship between EC quotas and estimated capacity in Italy, France, Spain and Portugal. The capacity-quota ratios were then used to compute and aggregate capacities for the hundreds of identified paste-processing plants in the five EC producer countries.

For the United States, our principal reference was a 1991 capacity estimate made by the Morning Star Company. This was adjusted for estimated plant closures since 1991 and compared with similar estimates from Durham, CTGA, and other industry sources. For the rest of the U.S. as well as for Turkey, Canada, and the major Latin American producers, we have used OECD estimates as well as those in our previous studies.

A number of countries with low output levels are included in the "other" category. Included are Venezuela, Peru, Israel, Taiwan, the Philippines, Cameroon, South Africa, Australia, New Zealand, and a group of Arabic and other Islamic countries, particularly Algeria, Tunisia, Egypt, and Morocco.

Several countries are excluded because of inadequate information. For the most part, they have little influence on world trade in tomato paste. In this group are the countries of eastern Europe and the former Soviet Union. For countries included in the "other" category, and to a lesser extent for Turkey, Canada, mid-western U.S., and major Latin American producers, information on the capacities of specific plants is scarce, incomplete, or based on estimates and projections made in different years from 1988 to the present. Thus interpretations based on data from this category should be treated with appropriate caution.

Full season capacity estimates disregard the seasonal pattern of tomato supply and the breaks in operation caused by equipment or personnel problems. We estimate that such constraints result in a practical operating capacity of 65 to 70% of the full season operating capacity.

Richard Sexton notes that the California industry has moved in two directions to better utilize plant capacities: (1) the harvest has been extended in some cases up to 20 weeks, and (2) some plants use non-harvest weeks to remanufacture paste into other products.

Four countries or groups of countries control over 85 percent of active world capacity for tomato paste: the U.S. (mostly California), 38%; the EC, 25%; the major Latin American producers, 13%; and Turkey, 9%. California and the EC together have 61% of world capacity; California and Italy, 47%.

It is difficult to assess how the former East Bloc countries we do not include would affect world capacity. Using what data we could assemble on past and current tomato and tomato products production, and using a series of assumptions about tomato utilization and the continuation of past relationships, we believe that these countries would add perhaps 8 million metric tons of capacity, or 32%, to the world total. This impressive figure depends on assumptions, extrapolations, and comparisons that are all subject to debate. Even if the estimate were to prove reasonably accurate, the impact of it on the world market remains far more modest than its magnitude would suggest because their production is mostly consumed domestically.

Even with missing or partial data for many countries, the structure of the processing industry shows some contrasting patterns. Most notably, production in California is concentrated in relatively large operations. Elsewhere in the world, only a handful of plants even approach the scale of the modal California size class. From the limited information available on the Turkish industry, capacity there appears to come closest to the California pattern. Among other large producers, the opposite extreme is best represented by Italy, where two-thirds of the plants are in the smallest size category and nearly 90 percent are in the bottom two. The dominant size of the Italian industry imposes much this same pattern on the entire EC structure, though plants in the other four countries also tend to cluster toward the low end of the size range.

In Latin America, Argentina resembles the Italian pattern while Chile more closely follows the California one. Despite data limitations, plants in Mexico and Brazil seem to be rather evenly distributed across the size range. Otherwise, as in the case with Turkey, structural data are too sketchy for definitive commentary. The processing plants in countries contained in the "other" category tend to be small. Since most capacity analyses focus on mid-size to large units, the number of extremely small plants in these countries may, if anything, be understated. The size of paste manufacturing plants is important because smaller plants tend to have higher unit costs and more variability in paste quality.

Definitions and Assumptions About Capacity

The level of paste output depends on capacity per unit of time, and the amount of time the facility is used. There is no simple and consistent way to measure capacity or its use since it involves a number of variables:

(a) Tons of fresh tomatoes processed (per line; per plant; per district, zone, or region; per country, etc.) per hour in operation;

(b) Hours in operation (one shift, two shifts; high season, shoulder and low seasons);

(c) Days in operation (seven-day week; six-day; sliding-length week according to processing demand; etc.);

(d) Weeks in operation (full season; variance by locality, by crop weather conditions, by proximity and power of competition, etc.; degree of dependence on local tomatoes; willingness to transport tomatoes for long distances from earlier or later producing areas);

(e) Estimates of equipment downtime; capability to vary speed of line operation, size and nature of packaging, etc.;

(f) For finished product capacity, conversion ratios of fresh equivalent tomatoes.

If there is any single incontrovertible indicator of overcapacity, it would have to be the existence of plants not utilized but capable of operation during the season&emdash;especially if these remain closed at the height of the season and for longer than one year. When a plant is operating, we assume it operates as close to engineered, installed, or optimal processing capacity as possible. This attainable or practical capacity probably approaches theoretical capacity only during a few peak weeks of the season; although with early, mid-season, and late crops, processors in certain countries manage to run at peak utilization for all but a few weeks of their harvests.

Over the entire processing season, utilized capacity in the paste industry is generally thought to average around 67%; for individual countries, estimated utilization rates run from as low as 40% to as high as 70% or, in exceptional instances such as Israel, even 85%.

Catherine Durham asserts that the theoretical season capacity for California can be calculated on the basis of maximum weekly capacities, which in turn, can be closely approximated from records of the quantities of tomatoes processed or delivered for processing during the four to five peak weeks of the season. Using this method, she estimated seasonal California capacity for 1989 at 7,520,000 tons of raw product. Other industry sources, presumably using methods rather similar to Durham's, have derived a comparable 1989 capacity figure of 7,588,000 tons.

In 1991, the Morning Star Company estimated that the engineered capacity for production of tomato paste in California was then 3,634 tons of raw product per hour&emdash;the equivalent of 9,158,137 tons for a season of 2,520 hours (105 days). This source indicates that two plants have since closed, reducing capacity by 285,763 tons to a 1993 total of 8,872,374 tons, or an operational capacity of about 5.9 million tons. The increase in installed capacity reflects investment decisions based on price signals and favorable weather that had already resulted in rising supplies of processing tomatoes.

The publication of data on the utilization of tomatoes for producing tomato paste in the United States was discontinued in 1988. Therefore, we rely on the estimate of the California Tomato Growers Association that 55 to 60 percent of tomatoes delivered to processors since 1988 have been processed into paste. Using the midpoint of that range, or 57.5 percent, we calculate that the quantity of tomatoes used for paste production was 4.4 million tons in 1989, 5.2 million tons in 1991 and 4.6 million tons (expected) in 1993. Based on the gross paste capacity estimates cited above, we calculate that capacity utilization has declined from 58.6 percent in 1989, to 56.5 percent in 1991 and to 52.1 percent in 1993.

If we assume that operational capacity amounts to two-thirds of gross theoretical capacity (thus accounting for seasonal patterns of tomato deliveries, as well as downtime for equipment), utilization still shows a downturn between 1989 and 1993, and an increase of about 660,000 tons in unused capacity. The operational capacity for 1993, 5.9 million tons, exceeds the record level of input achieved in 1991 by 0.8 million tons.

Our estimate of excess capacity is approximate and is obviously influenced by the total supply of tomatoes to be processed and by our assumptions about the portion allocated to paste production. Yet whatever the nature of the calculation, we cannot escape the reality that since 1989, processing capacity in California has expanded more rapidly than paste production, even with recent closures. This creates the potential for expanding production of raw product in the state by 1.3 million tons beyond the level expected in 1993 without a significant increase in investment.

Bieche has suggested that EC quotas generally equate with capacity, perhaps with varying conversion ratios for particular countries. It may well be reasonable to assume that quotas are consistently proportional to capacity, although we have not come up with any explanations for this. The possibility always exists that especially powerful and influential firms can win quotas closer to their full capacities than their ordinary pro rata share would get them.

Other technical variables with some bearing on capacity include age of equipment; degree to which aging, reconditioned, and new equipment has been installed and/or integrated; source countries and firms for equipment; and&emdash;in terms of pure functionality&emdash;speed of operation, variability of speeds, and propensity for breakdowns. While acknowledging these factors, we have not been able to estimate their impact on our calculations.

Outlook and Implications

With the preceding background, it is possible to forecast world tomato paste processing overcapacity for the 1993-94 marketing year. If FAS is expecting 16.6 million tons of processing tomatoes from the principal producing countries, and if the other processing tomato countries (not including, in the main, the former Eastern bloc) add to the total in the same relative proportion as their aggregate capacity has to total capacity (24.8%), we foresee a total processing tomato crop of somewhere around 20 million tons. At 60% utilization for paste, this would provide 12 million tons of tomatoes for paste processing. Since we calculate theoretical world capacity at 25.2 million tons and operating capacity at 16.9 million tons, this indicates an overcapacity in 1993 of about 5 million tons, or 30% of operating capacity.

Some countries may not find it feasible to improve capacity utilization very much. For example, Mexico is hindered by raw product constraints. Chile, in contrast, has modern, efficient farms and plants in place already and requires only the relaxation of tariffs or other economic incentives to expand production significantly.

Our impression is that many if not most people in the tomato industry do not talk or think about capacity in a global sense. Of those who do, few have much to say about how capacity is calculated&emdash;except to note units such as tons of fresh tomatoes per hour, day, week, or season, along with length of season. Their most nuanced comments refer to shoulder seasons, quality of equipment, plant shutdowns, and the like. Perhaps the best&emdash;and possibly the only&emdash;way to assess capacity in a thorough way is to conduct painstaking detective work in the field for all producer countries.

Our estimate of total world tomato paste manufacturing capacity derived from the analysis presented in this paper, shows that there is significant unused capacity of approximately 5 million tons. Attempts to utilize this volume would result in vastly greater production of tomatoes and, without a corresponding increase in product demand, would depress paste prices once again below profitable levels.
