Overview
Huahai Pharmaceutical, formally Zhejiang Huahai Pharmaceutical Co., Ltd., is a Chinese pharmaceutical company founded in 1989 and headquartered in Linhai, Zhejiang. It is a publicly traded company in China. Its business spans active pharmaceutical ingredients (APIs), finished pharmaceutical formulations, and contract development and manufacturing services (CDMO). The company serves domestic and international pharmaceutical markets. Its product and service areas include generic medicines and pharmaceutical ingredients, alongside manufacturing and development capabilities for customers. The supplied evidence identifies Huahai as a CDMO brand, while the company’s official website was returning a notice that the site had been suspended when checked. This dossier therefore does not rely on that site for detailed current product, leadership, or market claims.
History
Huahai Pharmaceutical is a Chinese pharmaceutical company established in 1989. It developed as a manufacturer in the pharmaceutical sector, with business spanning active pharmaceutical ingredients and finished formulations, as well as contract development and manufacturing services. The company is headquartered in Linhai, Zhejiang, and is publicly traded in China. Huahai serves pharmaceutical customers in China and international markets. Its combination of product manufacturing and contract services places it across both the supply of medicines and the pharmaceutical development and production chain. The evidence supplied for this dossier specifically describes it as a CDMO brand, but provides no detail on particular customer programs, facilities, or service capabilities. The company’s official website, https://huahai.com, displayed a notice stating that the site had been suspended by its administrator. As a result, that source could not substantiate current leadership, product catalogues, company announcements, or other present-day operating details. No specific dated corporate turning points are included here beyond the company’s establishment, as the provided evidence does not document them.

NDMA impurity detected in valsartan API, triggering global recalls and import restrictions
In 2018, NDMA was detected in valsartan active pharmaceutical ingredient (API) produced by Huahai Pharmaceutical. Multiple countries initiated recalls of affected medicines, and questions were raised about the timing of disclosure and recalls in China. The company halted production and described its risk assessment and communications with regulators; the United States and Europe subsequently imposed restrictions on products linked to its Chuannan production site. The incident was confined to the affected API and facility.
