up, which comprises a factor of about one million (10 gram → 10 ton quantities), is done by the fine chemical company. Standard products Non-exclusives, "standard" or "catalogue products" constitute the second most important outlet for fine chemicals after custom manufacturing. API-for-Generics are the most important sub-category. Because of patent expiries, over 60 of the top 200 drugs alone, representing aggregated sales of over $150 billion, have fallen into the public domain within the past decade. This, along with government-backed incentives, are causing global sales of generics to rapidly increase. Asian companies currently dominate the API-for-Generics business. They have multiple advantages of their low cost basis, their large home markets, and significant previous manufacturing experience compared to western manufacturers in producing for their domestic and other non-regulated markets. Financials Investment costs Investment costs for multipurpose plants are high in comparison with product output. However, they vary considerably, depending on the location, size of equipment and degree of sophistication (e.g., automation, containment, quality of equipment, complexity of infrastructure). An example for a cGMP multipurpose plant built in the US is shown in Table 9. The investment cost of $21 million comprises just the equipment and installation. The building, property and external services are excluded. For comparison purposes, the investment cost per m3 reactor volume is used. In this case, it is $0.9 million. The amount includes the cost of the reaction vessel itself plus an equitable part of the ancillary equipment, like feeding tanks, piping, pumps & process control. If larger or smaller reactors were installed, the unit cost per m3 would decrease or decrease with the exponent 0.5, respectively. Hence, by increasing the equipment size manufacturing costs on a per kilogram (kg−1) basis typically decrease substantially. Also, costs for a plant that is used for the production of non regulated intermediates only would be substantially lower. Pharma companies tend to spend up to ten times more for a plant with the same capacity. In contrast, investment costs in developing countries, particularly in India or China, are considerably lower. Manufacturing costs The raw material consumption and the conversion cost are the two elements that establish the manufacturing cost for a particular fine chemical. The former is determined primarily by the unit consumption and the purchasing cost of the materials used; the latter, by the throughput in kilograms per day in a given production bay. A precise calculation of the conversion cost
