Import Acyclovir — Buy in wholesale FOB from Supplier in China

Acyclovir is an antiviral API (active pharmaceutical ingredient) used primarily in the treatment of herpes simplex virus infections, varicella-zoster virus, and as a prophylactic against cytomegalovirus in immunocompromised patients. This listing from Hangzhou Shitai Biotech Co., Ltd. describes the material as a white to light yellow crystalline powder with a density of 1.77, a melting point of 256-257°C, and a boiling point of 595°C at 760 mmHg. The compound is stable under recommended storage but incompatible with strong oxidizing agents, requiring careful handling and segregation during synthesis and formulation operations.

The material conforms to the chemical classification under HS Code 2933790090, placing it within the heterocyclic compounds with nitrogen hetero-atoms category for customs and regulatory purposes. Typical pharmaceutical-grade acyclovir must meet stringent purity specifications, including assay (usually NLT 98.5% on anhydrous basis), related substances control, and residue on ignition limits per pharmacopeial standards such as USP or EP. The RTECS number UP0791400 and WGK Germany classification of 2 indicate moderate water hazard, relevant for effluent handling and environmental compliance during manufacture. Standard packaging for API-grade acyclovir includes double-layer polyethylene bags within fibre drums or aluminium-lined containers, with nitrogen flushing to prevent oxidative degradation typical for nucleoside analogues.

Primary buyers include finished dosage form manufacturers producing oral tablets, capsules, topical creams, and intravenous formulations. The supplier's location in Hangzhou, Zhejiang Province, places it within one of China's established pharmaceutical manufacturing clusters, with access to Shanghai Port for export logistics. Importers should confirm GMP compliance status, DMF registration availability, and whether the site holds valid API registration for target markets (US FDA, EDQM CEP, or MF in Japan). Trade terms, MOQ, and lead time are not stated in the source data and must be confirmed directly with Hangzhou Shitai Biotech Co., Ltd.

Hangzhou Shitai Biotech Co., Ltd. is located at #2-1214, West Business Center, Gongshu District, Hangzhou, Zhejiang Province, China, postal code 310000. The supplier holds a harbor trust tier on the platform, which represents a baseline verification level rather than an advanced assurance status. The response rate is recorded as 0.00% with an average response time of 0 hours, indicating no engagement history through the platform's messaging system. This absence of response data is a material consideration for buyers evaluating communication reliability.

The supplier's profile via the source description provides no information about manufacturing capabilities, quality certifications, regulatory filings, years in operation, or clientele. No claims about GMP certification, ISO accreditation, patent holdings, or export markets are present in the available data. Buyers must independently verify the company's manufacturing scope (whether it operates as a trader, manufacturer, or hybrid), its actual production capacity for acyclovir, and its regulatory documentation status for target pharmaceutical markets. The listing presents physical and chemical characterisation data for the product but does not assert compliance with any specific pharmacopeia.
