The Company uses a wide array of raw materials in the conduct of its businesses.
For its Human Health products, the Company generally will have a primary and secondary supplier for its critical raw materials. Prices for these raw materials are generally stable except for the petroleum-based solvents where prices can vary with market conditions.
For its Bioproducts products, the Company buys materials from many suppliers and is generally not dependent on any one supplier or group of suppliers. There is a well-established market for raw fetal bovine serum but price and supply are cyclical and fluctuate. Bovine spongiform encephalopathy, also known as mad cow disease, can periodically restrict the locations from which the Company can import fetal bovine serum. The Company also has a long-term contract with one company to supply agarose, the key raw material used to make electrophoresis media products.
The other key raw materials used by all segments of the Company are advanced organic intermediates that generally have been in adequate supply from multiple suppliers.
