Our ability to increase sales of our products depends in part upon our ability, in a very short timeframe, to ramp up our manufacturing capacity and to mobilize our supply chain. If we are unable to do so, our customers could obtain products from our competitors, which would reduce our market share, harm our reputation as a trusted partner and impact our results of operations. Ensuring a robust and resilient supply chain is critical for us to meet the demand, quality and technological requirements of our customers. We rely on the timely delivery of parts, materials and services, including components and subassemblies, from our suppliers and contract manufacturers.
The Company's strategies to limit its reliance on single, sole or limited source suppliers and utilize alternative sources are not feasible or practical in all circumstances. For example, we rely on single, sole or limited source suppliers for certain raw materials that are critical to manufacturing our products, such as plastic polymers, filtration membranes, abrasive particles, petroleum coke and other materials. If we were to lose any of these critical sources, or there is an industry-wide increase in demand for, or discontinuation of, raw materials or components used in our products, it could be difficult or impossible to find an alternative supplier, which could adversely affect our operations. In addition, qualifying alternative suppliers or materials (or relocating manufacturing) can be time-consuming and costly due to customer qualification requirements, regulatory approvals,and the technical sensitivity of many of our products. Disruptions to transportation routes, ports, air freight capacity, or regional infrastructure in Asia (including in locations where we or our suppliers manufacture or where key customers operate) could further delay deliveries, increase costs, or reduce our ability to serve customers.
Several factors outside of our control, including, but not limited to, surges in demand for semiconductors, changes in trade policies, the imposition of foreign export controls on critical materials and minerals and international conflicts, have resulted in, and may in the future result in, a shortage of raw materials and components needed to manufacture and deliver our products, higher raw materials costs, costly and time-consuming re-qualification of products manufactured with new raw materials and delays in, and unpredictability of, shipments due to transportation interruptions. These results could harm our reputation or the competitiveness of our products. Such shortages, delays and unpredictability have adversely impacted, and may impact in the future (1) our suppliers' ability to meet our demand requirements, (2) our manufacturing operations, (3) our ability to meet customer demand, (4) our gross margins and (5) our other operating results. Our actions to counteract adverse impacts to our gross margins and other operating results could be unsuccessful or reduce demand, which would adversely impact our revenue. Additionally, our suppliers may not have the capacity to meet increases in our demand for raw materials and other components, in turn, making us unable to meet customer demand for our products. If our suppliers or sub-suppliers are unable to maintain their operations due to operational restrictions or financial hardship caused by an economic slowdown or recession, we may need to increase our safety stocks of raw materials or components or alter our payment terms with such suppliers, including prepaying for raw materials. These measures could reduce our available working capital, increase our inventory carrying costs, and negatively impact our liquidity and overall financial flexibility.
Further, increased restrictions imposed on a class of chemicals known as per- and polyfluoroalkyl substances ("PFAS"), which are used in a number of products, including parts and materials that are incorporated into our products, may negatively impact our supply chain due to the potentially decreased availability, or non-availability, of PFAS-containing products. Proposed regulations under consideration could require that we transition away from the usage of PFAS-containing products, which could adversely impact our business, operations, revenue, costs, and competitive position. Suitable replacements for PFAS-containing parts and materials may not be available at similar performance and costs, or at all.
