About Hangzhou Hysen Pharma - Agriculture Supplier in China

Hangzhou Hysen Pharma is located in China and currently lists five active products in its catalogue. All listed items belong to the pharmaceutical active ingredient segment, which is recorded under the agriculture top category in the supplier’s profile. The product portfolio includes the aromatase inhibitors Anastrozole and Letrozole (with intermediate forms), the estrogen‑receptor degrader Fulvestrant, the bisphosphonate Zoledronic Acid, and the anti‑androgen Bicalutamide (also with intermediate). Each product is identified without specific HS codes in the public catalogue, but they fall within the HS chapter 29 family for organic chemical compounds. The supplier is marked as an imported tier with a harbor trust level, indicating that it operates through established trade channels.

The catalogue does not disclose manufacturing capacity, certifications, or batch sizes, focusing solely on the chemical names. Buyers can expect the listed APIs to be supplied in bulk powder or crystalline form, typical of API trade. Standard industry practice for these molecules requires a minimum purity of 99.5 % as determined by HPLC, with impurity limits defined by ICH Q3R2. Regulatory compliance normally involves GMP certification and a Certificate of Analysis for each batch. Potential importers should verify that the products meet the pharmacopoeial specifications relevant to their target markets.

Product Range and Specialties of Hangzhou Hysen Pharma

The supplier’s catalogue lists five distinct active pharmaceutical ingredients: Anastrozole, Letrozole (and its intermediate), Fulvestrant, Zoledronic Acid, and Bicalutamide (and its intermediate). In the global API market these compounds are commonly offered in grades ranging from 98 % to 99.9 % purity, with the highest grade used for final drug substance manufacture. Typical specifications include assay limits ±0.5 %, moisture content below 0.5 %, and residual solvents complying with ICH Q3C limits. Packaging for bulk APIs is usually 25 kg or 50 kg HDPE drums, sealed with tamper‑evident liners, or in ISO‑standard bulk containers for larger shipments.

Industry buyers often request additional data such as particle size distribution (for compounds intended for formulation), polymorphic form confirmation, and stability data under ICH‑controlled conditions. For intermediates, a defined synthetic route and impurity profile are standard expectations. These additional parameters help downstream manufacturers assess suitability for their specific formulation processes.

Trade and Export Information - Hangzhou Hysen Pharma

Export of pharmaceutical APIs from China is concentrated toward the United States, European Union, Japan, and emerging markets in Southeast Asia, where GMP‑compliant raw materials are in high demand. HS chapter 29 (organic chemicals) is the primary customs classification for the listed molecules, and customs authorities frequently request a detailed product description, HS code, and a commercial invoice indicating the intended pharmaceutical use. Commonly required certifications include GMP audit reports, ISO 9001 quality‑management certificates, and a Certificate of Analysis for each shipment. Logistics for bulk APIs typically use 20‑foot or 40‑foot containers with temperature‑controlled options only when stability data dictate; otherwise standard dry containers are used, with Incoterms such as FOB or CIF prevailing in most contracts.

China’s pharmaceutical export regime mandates compliance with the National Medical Products Administration (NMPA) and alignment with international standards such as ICH Q7 for active ingredient manufacturing. Importing countries often perform pre‑shipment verification through third‑party inspection agencies, focusing on label accuracy, batch traceability, and compliance with the destination country’s pharmacopoeia.

Sourcing from Hangzhou Hysen Pharma - Buyer Guidance

When sourcing from Hangzhou Hysen Pharma, buyers should request the latest GMP certificate, a full Certificate of Analysis for the specific batch, and any available stability or impurity profiles. Verifying the assay range, residual solvent limits, and moisture content against the buyer’s target specifications is essential before confirming an order. It is also advisable to obtain a sample for independent testing, especially for intermediates where synthetic route confirmation may be required.

Buyers should confirm the packaging format (drum size, inner liner material) and ensure that the shipping terms match their logistics capabilities. Clarify the minimum order quantity, which for bulk API trade commonly starts at 10 kg per compound, and negotiate lead times that reflect the supplier’s production scheduling, typically 30‑45 days from order confirmation. Documentation such as a Material Safety Data Sheet (MSDS) and export customs declaration should be reviewed to avoid clearance delays.

What active pharmaceutical ingredients does Hangzhou Hysen Pharma list in its catalogue?

The catalogue includes Anastrozole, Letrozole (and its intermediate), Fulvestrant, Zoledronic Acid, and Bicalutamide (and its intermediate).

Are HS codes provided for the listed products?

Specific HS codes are not included in the public catalogue, but the products fall under HS chapter 29 for organic chemical compounds, which is the standard classification for pharmaceutical APIs.

What purity levels are typical for these APIs?

Industry practice expects a minimum assay of 99.5 % purity, with higher grades of 99.8‑99.9 % used for final drug substance production. Purity is usually confirmed by HPLC analysis.

Which certifications should a buyer request from this supplier?

Buyers should request the supplier’s current GMP certificate, ISO 9001 or equivalent quality‑management documentation, and a Certificate of Analysis for each batch. Additional certificates may be required by the importing country.

What are the usual packaging formats for bulk API shipments?

Bulk APIs are commonly packed in 25 kg or 50 kg HDPE drums with tamper‑evident liners, or in ISO‑standard bulk containers for larger volumes. Packaging details should be confirmed before order finalisation.

What are typical minimum order quantities and lead times?

Minimum order quantities for bulk APIs often start around 10 kg per compound. Lead times generally range from 30 to 45 days after order confirmation, depending on production scheduling and required documentation.

How should a buyer handle regulatory compliance for imported APIs?

Buyers need to ensure the supplied API meets the pharmacopoeial standards of the destination market, verify GMP compliance, and obtain all required import permits and documentation such as the MSDS and customs declaration.

What logistics terms are commonly used for shipping these products?

Common Incoterms include FOB (Free on Board) and CIF (Cost, Insurance, and Freight). Shipping is typically performed in dry containers unless temperature control is specified in the product’s stability data.
