Most of our toy and game products are manufactured by third-party manufacturers, the majority of which are in China, with a significant amount of our product sourcing also coming from manufacturers in the U.S., Vietnam, India and Japan. Should changes be necessary, our external sources of manufacturing can be shifted, over a significant period of time, to alternative sources of supply. Working with vendors who have not historically manufactured products for us means these new vendors must successfully develop the capability to manufacture our products to the quality and safety standards we require and within the tight timeframe required by our customers. Newer and less experienced vendors are more susceptible to product quality, logistics and other issues, due in part to their less mature infrastructure or unfamiliarity with our product standards.
If we were prevented or delayed in obtaining products or components for a material portion of our product lines due to economic, political, civil, labor or other factors beyond our control, including work stoppages, slowdowns or strikes, natural disasters, adverse health conditions or pandemics, our ability to manufacture would be adversely affected and our operations may be substantially disrupted, potentially for a significant period of time. This delay could significantly reduce our revenues and profitability and harm our business while alternative sources of supply are secured.
Given that our toy and game manufacturing is conducted by third-party manufacturers, health conditions and other factors affecting social and economic activity where our manufacturers are located may affect the movement of people and products into and from those locations to our major markets, including North America and Europe. Further, increases in the costs of labor and other costs of doing business in markets where we manufacture, could also have a significant negative impact on our operations, revenues and earnings. Prolonged disputes or slowdowns at west coast or other ports can negatively impact both the time and cost of transporting goods into the U.S. Natural disasters or health pandemics impacting our manufacturers had and can have a significant negative impact on our business.
Further, as described elsewhere, the imposition or threat of tariffs, border adjustment taxes, trade sanctions or other regulations or economic penalties by the U.S. or the European Union against products imported by us from China or other foreign countries, or the loss of "normal trade relations" status with China or other foreign countries in which we operate, could significantly increase our cost of products imported into the U.S. or Europe, shift more orders from direct import to domestic sales, put additional shipping and warehousing burdens on us, delay the time of our sales to retailers, result in lost sales, and otherwise harm our business. Additionally, the suspension of the operations of a third-party manufacturer by government inspectors in China or another market in which we source products could result in delays to us in obtaining product and may harm sales.
We require our third-party manufacturers to comply with our Global Business Ethics Principles, which are designed to prevent products manufactured for us from being produced under inhumane or exploitive conditions. Notwithstanding these requirements and our monitoring and testing of compliance with them, there is always a risk that one or more of our third-party manufacturers will not comply with our requirements and that we will not immediately discover such non-compliance. Any failure of our third-party manufacturers to comply with labor, consumer, product safety or other applicable requirements in manufacturing products for us could result in damage to our reputation, harm sales of our products and potentially create liability for us.
