We conduct business in many countries, including emerging markets in Asia, Latin America, and Eastern Europe, and these operations represent a significant portion of our sales and earnings. In addition to the currency risks discussed below, our international operations pose other potential substantial risks and problems for us, including the following:
- recently reduced market demand in our core segments in China and the current economic conditions in this region;- local tariffs and trade barriers and the potential for retaliatory tariffs;- additions or revisions to a country's legal and regulatory requirements;- difficulties in staffing and managing local operations and/or mandatory salary increases;- credit risks arising from financial difficulties facing local customers and distributors;- difficulties in protecting intellectual property;- nationalization of private enterprises which may result in the confiscation of assets, as we hold significant assets around the world in the form of property, plant, and equipment, inventory, and accounts receivable, as well as $13.9 million of cash at December 31, 2024, in our Chinese subsidiaries;- restrictions on investments and/or limitations regarding foreign ownership;- adverse tax consequences, including tax disputes and imposition or increase of withholding and other taxes on remittances and other payments by subsidiaries;- domestic purchasing requirements that could favor local competition;- other uncertain local economic, political, and social conditions, including inflation, hyper-inflation, and other decreases in purchasing power, or periods of low or no productivity growth;- reduced foreign investment and/or demand;- credit tightening or reduction in credit availability for local customers;- geopolitical topics within Asia and other regions; and - emerging markets can be volatile and change quickly.
China represents a significant portion of our business and financial results and has an important role in our global supply chain. For example, our Chinese operations accounted for 16% of sales to external customers, 29% of total segment profit, and approximately 30% of our global production during 2024. In recent years, geopolitical tensions have increased, particularly between the United States and China. Among other issues, these geopolitical topics have resulted in increased tariffs and trade restrictions. The Chinese government and other governments have also increased their focus on domestic purchasing requirements. In addition, due to increasing political tensions and potential tariff increases, many companies are seeking increased flexibility in their supply chains that may result in reduced foreign investment in China. The Chinese economy remains under pressure and is impacted by challenges with the country's real estate market that affects domestic consumption and has historically been a source of funds for government stimulus. These risks, all of which will be exacerbated by trade wars and tariffs, could lead to reduced sales in China, as well as higher costs.
After benefiting from significant growth in 2022 and 2021, market demand in China declined significantly during the second half of 2023, which continued in 2024. Our business is significantly impacted by market demand in our core segments of pharma/biopharmaceutical, food manufacturing, and chemical. Market conditions also can be volatile and change quickly, as experienced in 2023.
We must also comply with regulations regarding the conversion and repatriation of funds earned in local currencies. For example, we need government approval to convert earnings from our operations in China into other currencies and to repatriate these funds. If we cannot comply with these or other applicable regulations or these regulations are amended to make it more difficult to repatriate the funds, we may face increased difficulties in using cash generated in China.
We are required to comply with various import, export control, and economic sanctions laws, which may affect our transactions with certain customers, business partners, and other persons, including in certain cases dealings with or between our employees and subsidiaries. We address below the topic of economic sanctions laws related to Russia's invasion of Ukraine, which commenced in February 2022. In certain circumstances, export control and economic sanctions regulations may prohibit the export of certain products, services, and technologies, and in other circumstances, we may be required to obtain an export license before exporting a controlled item. Failure to comply with any regulations and sanctions could result in civil and criminal actions, monetary and non-monetary penalties, disruptions to our business, limitations on our ability to import and export products and services, and damage to our reputation.
In response to Russia's 2022 invasion of Ukraine, the U.S., European Union, and other countries imposed economic sanctions on Russian entities, while Russia enacted countermeasures. We continue to monitor developments and applicable sanctions.
Since February 2022, we have suspended all shipments to Russia. In 2021, Russia and Ukraine accounted for approximately 1% of our net sales, and as of December 31, 2024, 2023, and 2022, our assets and liabilities in both countries remained immaterial. We also do not have manufacturing in Russia or Ukraine.
The EU Council has been working to expand renewable energy use, reduce consumption, and diversify energy sources due to reduced Russian energy supplies. This may impact energy availability and costs in Europe.
We do not manufacture in the Middle East and sales in the region account for less than 1% of total revenue. Ongoing conflicts may impact demand locally and globally while disrupting supply chains, increasing costs, and reducing shipping capacity, all of which could affect our financial results and customer demand. Escalating global conflicts, including in Ukraine and the Middle East, have heightened economic and geopolitical uncertainty.
Estimating the impact of ongoing global conflicts on supply chain disruptions and energy shortages is challenging. However, the Ukraine invasion and Middle East conflict could negatively affect our financial results and pose risks to our business. Additionally, uncertainties surrounding these conflicts persist, and their effects on the global economy and market conditions can change rapidly.
We continue to monitor developments in these conflicts and any related sanctions.
