Our business depends on a continuous supply of raw materials. The principal raw materials used in our business include platinum, stainless steel, gold, titanium, nitinol, lithium, palladium, iridium, tantalum, nickel cobalt, ruthenium, gallium trichloride, vanadium oxide, CFx and plastics. The supply and price of raw materials may be susceptible to fluctuations due to transportation issues, government regulations, price controls, foreign civil unrest, tariffs, worldwide economic conditions or other unforeseen circumstances, including the continuing impact of the global pandemic. Increasing global demand for raw materials has caused prices of certain materials to increase. Significant increases in the cost of raw materials that cannot be recovered through increases in the prices of our products could adversely affect our results of operations. There can be no assurance that the marketplace will support higher prices or that price increases and productivity gains, procurement deflation projects or savings will fully offset any raw material cost increases in the future. In addition, there are a limited number of worldwide suppliers of several raw materials needed to manufacture our products. For reasons of quality, cost effectiveness or availability, we obtain some raw materials from a single supplier. Although we work closely with our suppliers to seek to ensure continuity of supply, we may not be able to continue to procure raw materials critical to our business at all or to procure them at acceptable price levels. A disruption in deliveries from our suppliers, price increases or decreased availability of raw materials could have an adverse effect on our ability to meet our commitments to our customers and increase our operating costs. Finally, continued uncertainty around inflationary pressures and macroeconomic conditions have increased the risk of creating new, or exacerbating existing, economic challenges we face with regard to our supply chain. Inflation has the potential to increase our overall cost structure, and sustained inflation has resulted in, and may continue to result in, higher interest rates and capital costs, increased shipping costs, supply shortages, increased costs of labor, weakening exchange rates, and other similar effects. While we have implemented cost containment measures and taken other actions to offset these inflationary pressures in our global supply chain, we may not be able to completely offset all the increases in our operational costs.
We rely on third-party manufacturers to supply many of the products and subcomponents that are incorporated into our products and components. These third-party manufacturers have their own complex supply chains and related risks, whether due to the continuing impact of the global pandemic, the shipping risks described below, the military conflict between Russia and Ukraine or other causes. They are subject to raw material price and availability risks similar to those described above. Manufacturing problems may occur with these and other outside sources, as a supplier may fail to develop or manufacture products and subcomponents for us on a timely basis, or may supply us with products and subcomponents that do not meet our quality, quantity and cost requirements. Our third-party suppliers are also subject to shipping risks, including container shortages, blocked shipping lanes, and port backlogs. If any of these problems occur, we may be unable to obtain substitute sources for these products and subcomponents on a timely basis or on terms acceptable to us, which could harm our ability to manufacture our own products and components profitably or on time. In addition, to the extent the processes our third-party suppliers use to manufacture products and subcomponents are proprietary, we may be unable to obtain comparable products and subcomponents from alternative suppliers.
Our business is also subject to risks associated with U.S. and foreign legislation, regulations and trade agreements relating to the materials we import, including the tariffs on steel that the U.S. has imposed and other quotas, duties, tariffs or taxes or restrictions on imports, which could adversely affect our operations and our ability to import materials used in our products at current or increased levels. We cannot predict whether additional U.S. and foreign customs quotas, duties (including antidumping or countervailing duties), tariffs, taxes or other charges or restrictions, requirements as to where raw materials must be purchased or other restrictions on our imports will be imposed in the future or adversely modified, or what effect such actions would have on our costs of operations. Future quotas, duties or tariffs may adversely affect our business, financial condition, results of operations or cash flows. Future trade agreements could also provide our competitors with an advantage over us, or increase our costs, either of which could adversely affect our business, financial condition, results of operations or cash flows.
