Therefore, international buyers should remain agile and informed about market trends, technological advancements, and regulatory changes. By doing so, they can position themselves for success in an increasingly competitive marketplace. Now is the time to reassess your sourcing strategies—invest in quality, establish strong partnerships, and future-proof your supply chain.
