St. Louis, Mo. — Sigma-Aldrich Corporation (Nasdaq: SIAL) today announced the launch of a redesigned website for China, www.sigmaaldrich.com/china, which offers more relevant content, improved search results, enhanced product detail pages and a completely translated homepage. The Company also unveiled its new Vetec brand product line, providing the China market with an even broader portfolio of reliable-quality laboratory reagents, designed to meet the research needs of local customers. These additions complement Sigma-Aldrich’s existing presence in China and further enhance the Company’s localization strategy.

“Sigma-Aldrich has a well-established presence in China,” said Shaf Yousaf, Chief Marketing Officer. “The Company is widely known for its direct sales team with strong customer relations, its vast distribution network and its expanding Asia-Pacifc footprint. China represents a signficant opportunity for us. We expect the Vetec brand and enhanced local web presence will support organic growth, while further demonstrating our long-term commitment to this market.”

All of the products offered under the new Vetec brand have been tested to ensure they meet Sigma-Aldrich’s quality control standards for integrity, consistency and reliability and are certified by Sigma-Aldrich using methodologies employed worldwide.

“Sigma-Aldrich is focused on localization in Asia-Pacific to better meet the needs of our customers in the region,” said Wilson Wang, Managing Director, Greater China. “Vetec and the new website were designed with the Chinese customer in mind. Vetec provides scientists with a reliable-quality alternative for the chemicals and biochemicals they use daily and will help the Company meet the needs of new customer segments. The website will give those same customers a more optimal online experience.”

Based on input from extensive customer interviews and usability testing, the new China website offers relevant localized content, local product promotions, a high touch customer experience with easy access to customer service, a completely translated homepage and improved search results and product detail pages. It is expected to strengthen the already powerful connection between Sigma-Aldrich and the Chinese research community.

“The improved layout of the new website strongly supports best practices observed in China,” said Amanda Halford, Sigma-Aldrich Vice President of Digital Marketing and Customer Experience. “With traffic to our website in China growing significantly each month, we expect these enhancements will accelerate the already extensive use of the site for research and convenient procurement of scientific products.”
