The article details how the United States’ trade policies, particularly the tariffs introduced during Donald Trump’s presidency, have significantly affected the global supply chain for screws. Taiwan, which has historically been the leading supplier of screws to the U.S., is now facing challenges due to these tariffs. The impact on businesses such as Sheh Fung, which produce screws for construction and home improvement projects, is notable. As a result, the company’s ability to meet U.S. demand has been constrained, raising concerns about the long-term implications for the industry. Additionally, the article mentions that the tariffs have disrupted the economic environment for Taiwanese manufacturers, leading to a potential decline in exports and increased costs for American consumers.
