About Xi'an Guanyu Bio-Tech Co., Ltd - Pharmaceutical API Supplier in China

Xi'an Guanyu Bio-Tech Co., Ltd is based in Xi'an, China and currently lists five active products in its catalogue. The products are the flavonoid Luteolin, the camptothecin derivative 10‑hydroxycamptothecin, and three widely used anticancer active pharmaceutical ingredients (APIs): Docetaxel, Irinotecan Hydrochloride and Paclitaxel. All items fall under the HS‑code families for medicinal chemicals (typically 2933) and for pharmaceutical preparations (3004) as recognized in international customs classifications. The supplier is recorded as an imported tier with a harbor trust tier, indicating that it operates through standard import‑export channels.

The catalogue focuses exclusively on high‑purity pharmaceutical intermediates and APIs that are used in oncology and anti‑inflammatory formulations. Each entry is presented by its chemical name without additional branding, reflecting a product‑centred listing rather than a brand portfolio. The five compounds together represent a niche segment of the global API market where precise assay values and stringent impurity limits are mandatory.

Product Range and Specialties of Xi'an Guanyu Bio-Tech Co., Ltd

The listed compounds represent typical pharmaceutical‑grade APIs. Luteolin is commonly supplied as a crystalline powder with a purity assay of ≥98 % and meeting USP/NF specifications for flavonoids. 10‑Hydroxycamptothecin, a camptothecin analogue, is usually offered at ≥99 % purity, with residual solvent limits defined by ICH Q3C. Docetaxel, Irinotecan Hydrochloride and Paclitaxel are standard anticancer agents that are usually provided as white to off‑white powders, each with assay values of ≥98.5 % and compliance to USP, EP or JP monographs. Typical specifications include appearance, assay, water content (≤0.5 %), heavy metal limits (≤10 ppm) and microbial limits (≤100 CFU/g).

Trade and Export Information - Xi'an Guanyu Bio-Tech Co., Ltd

China is one of the world’s largest exporters of pharmaceutical APIs, and shipments from Xi'an typically target North America, the European Union and Southeast Asian markets. The HS‑code 2933 covers organic chemicals used as medicinal products, while finished API preparations may be classified under HS‑code 3004 when packed for export. Importing companies usually require evidence of GMP compliance, a Certificate of Analysis (CoA) for each batch, and, where applicable, ISO 9001 certification from the supplier. Logistics for powdered APIs often involve bulk containers such as 25 kg HDPE drums or 20 ft containers with moisture‑controlled liners; common Incoterms are FOB or CIF, with customs documentation including a commercial invoice, packing list and export license from Chinese authorities.

Sourcing from Xi'an Guanyu Bio-Tech Co., Ltd - Buyer Guidance

Buyers should request a recent CoA that details assay, impurity profile, residual solvent levels and microbial limits for each API. Verification of the supplier’s GMP status, either through a third‑party audit report or an ISO 9001 certificate, is a standard prerequisite. Samples are typically supplied in 100 g to 500 g quantities for analytical testing; buyers should confirm the sample’s packaging material to avoid moisture uptake. Prior to placing a full order, confirm the MOQ (often 5 - 10 kg per API), expected lead time (normally 30 - 45 days from order confirmation), and the proposed packaging (e.g., sealed HDPE drums with desiccant) to ensure regulatory compliance throughout the supply chain.

What types of pharmaceutical APIs does Xi'an Guanyu Bio-Tech list?

The supplier lists five APIs: Luteolin, 10‑hydroxycamptothecin, Docetaxel, Irinotecan Hydrochloride and Paclitaxel, each presented as high‑purity powders suitable for drug development.

Are certificates of analysis available for each product?

Buyers can request a CoA for every batch; the CoA includes assay, impurity limits, residual solvent data and microbial specifications in line with USP/EP standards.

Which certifications are typically required for these APIs?

Importers usually ask for GMP compliance documentation, ISO 9001 certification and, where applicable, a Certificate of Suitability (CE) for the specific API.

What is the usual minimum order quantity for the listed APIs?

Typical MOQs for powdered APIs range from 5 kg to 10 kg per compound, depending on the specific chemical and packaging configuration.

What packaging formats are used for shipment?

Products are commonly packed in sealed HDPE drums or inner‑liners within 20 ft containers, with desiccant packs to control moisture during transit.

Which Incoterms are most frequently applied?

Export transactions frequently use FOB (Free on Board) or CIF (Cost, Insurance, Freight) terms, allowing the buyer to arrange insurance and inland transport as needed.

What lead times should a buyer expect?

Standard production and export lead times are 30 to 45 days after order confirmation, subject to batch testing and customs clearance.

Which regions import these Chinese APIs most often?

The primary importing regions are North America, the European Union and Southeast Asia, where the APIs are incorporated into oncology and anti‑inflammatory drug pipelines.
