About Sichuan Weiekqi Biological Technology Co., Ltd. - Chemicals & Allied Products Supplier in China

Sichuan Weiekqi Biological Technology Co., Ltd. is based in Sichuan province, China, and currently lists 13 active products. The supplier is classified under the "Chemicals & Allied Products" and "Agriculture" categories. Its catalogue includes a range of phytochemical and alkaloid compounds such as Licoflavonol, Morusin hydroperoxide, Stearyl Glycyrrhetate, Hederagenin, and Dipotassium Glycyrrhetate. Several items are accompanied by HS codes in the 2932, 2933, 2938 and 2939 series, for example Licoisoflavone B (HS 2932.90), Halofuginone (HS 2933.59), Febrifugine (HS 2933.79), Gelsemine (HS 2939.90), Deoxyandro Grapholide (HS 2932.99) and Desacetylcinobufagin (HS 2938.90). The material descriptions indicate synthetic or natural origins, with molecular formulas provided for selected compounds.

The product set also contains specialized indole alkaloids, diterpenoid lactones, and amino‑acid derivatives such as L‑Cysteine. Typical supply forms are fine powders or granules suitable for analytical or bulk manufacturing processes. Purity levels for fine‑chemical imports from China are commonly reported above 98 % by HPLC, with moisture content below 0.5 % for most organic compounds. Buyers often require a Certificate of Analysis (CoA) that lists assay, impurity profile, heavy‑metal limits and microbial limits in accordance with USP or EP standards. The supplier’s product portfolio therefore spans a spectrum of bio‑active molecules used in pharmaceutical, nutraceutical and cosmetic research.

Product Range and Specialties of Sichuan Weiekqi Biological Technology Co., Ltd.

The catalogue lists thirteen distinct chemicals, including Licoflavonol, Morusin hydroperoxide, Stearyl Glycyrrhetate, Hederagenin, Dipotassium Glycyrrhetate, Licoisoflavone B (HS 2932.90), Halofuginone Hydrobromide (HS 2933.59), Febrifugine (HS 2933.79), Gelsemine (HS 2939.90), Deoxyandro Grapholide (HS 2932.99), Atractylodin, Desacetylcinobufagin (HS 2938.90) and L‑Cysteine. Each entry provides a chemical name and, where available, an HS‑code and molecular formula, reflecting a focus on fine‑chemical and bio‑active raw materials.

In the global fine‑chemical market, compounds in HS chapters 2932‑2939 are typically offered in analytical grade (>99 % purity) or pharmaceutical grade (>98 % purity) specifications. Standard quality parameters include assay by HPLC or GC, water content below 0.5 %, loss on drying under 0.2 %, and limits on heavy metals (e.g., Pb < 10 ppm). Common packaging formats are 25 kg or 100 kg paper bags, and 20 ft or 40 ft containers for bulk shipments. Buyers in pharma and nutraceutical sectors frequently request compliance with GMP, ISO 9001, and, where applicable, REACH registration for EU imports.

Trade and Export Information - Sichuan Weiekqi Biological Technology Co., Ltd.

China is a leading exporter of fine chemicals classified under HS 2932‑2939, supplying markets in Europe, North America, and Southeast Asia. Export shipments are usually arranged on a FOB or CIF basis, with bulk powders packed in multi‑layer paper bags placed inside 20 ft or 40 ft containers. Importers often require pre‑shipment documentation such as a commercial invoice, packing list, Certificate of Origin, and a Material Safety Data Sheet (MSDS) that meets local regulatory requirements (e.g., OSHA, EU CLP). For pharmaceutical or nutraceutical applications, the receiving party typically asks for a Certificate of Analysis (CoA) and evidence of GMP compliance, while EU buyers may also request a REACH registration number or a self‑classification statement. Logistics providers handling these HS codes must observe any applicable customs duties and anti‑dumping measures that apply to synthetic organic chemicals.

Sourcing from Sichuan Weiekqi Biological Technology Co., Ltd. - Buyer Guidance

When sourcing from this supplier, request a recent Certificate of Analysis that details assay, impurity profile, moisture and heavy‑metal limits in accordance with USP, EP or JP standards. Ask for an up‑to‑date Material Safety Data Sheet and, if the product is intended for food or supplement use, verify that the supplier can provide a GMP or ISO 9001 certificate. Confirm the packaging size (e.g., 25 kg or 100 kg bags) and the container type that matches your logistics network, and clarify the Incoterm (FOB or CIF) before finalising the order. It is advisable to obtain a sample batch for independent testing, especially for compounds with complex stereochemistry such as alkaloids or diterpenoids. Verify that any required regulatory registrations (e.g., REACH for the EU or FDA Food Additive status for the US) are in place before importation.

What HS codes are associated with the products listed by Sichuan Weiekqi Biological Technology?

The catalogue includes HS codes 2932.90 for Licoisoflavone B, 2933.59 for Halofuginone, 2933.79 for Febrifugine, 2939.90 for Gelsemine, 2932.99 for Deoxyandro Grapholide, and 2938.90 for Desacetylcinobufagin. Other listed chemicals do not have a specific HS code in the provided data.

Which quality documents should a buyer request before purchasing these chemicals?

Buyers should request a Certificate of Analysis (CoA) showing assay, impurity profile, moisture and heavy‑metal limits, a current Material Safety Data Sheet (MSDS), and, where applicable, GMP or ISO 9001 certification. For EU imports, a REACH registration or self‑classification statement is also advisable.

What are the typical purity levels for fine‑chemical imports from China in these HS categories?

Importers usually receive analytical or pharmaceutical grade material with purity greater than 98 % by HPLC, and moisture content below 0.5 %. Heavy‑metal limits are commonly set at 10 ppm for lead and similar thresholds for other metals.

In what packaging formats are these chemicals normally shipped?

Bulk powders are commonly packed in multi‑layer paper bags of 25 kg or 100 kg, which are then placed inside standard 20 ft or 40 ft shipping containers. The exact packaging can be confirmed with the supplier for each product.

Which markets typically import the types of compounds offered by this supplier?

Typical import markets include pharmaceutical manufacturers, nutraceutical companies, and cosmetic ingredient firms in Europe, North America, Japan and Southeast Asia. Academic and research institutions also source these specialized phytochemicals for bio‑activity studies.

What Incoterms are most frequently used for shipping these fine chemicals from China?

FOB (Free on Board) and CIF (Cost, Insurance, Freight) are the most common Incoterms for bulk chemical shipments from Chinese exporters, allowing the buyer to choose the level of responsibility for freight and insurance.

How long does it usually take to receive a sample of a listed compound?

Sample lead times from Chinese fine‑chemical suppliers generally range from 7 to 14 days after order confirmation, depending on stock availability and the need for customs clearance for the sample parcel.

Are there any regulatory restrictions on importing alkaloid‑type compounds such as Gelsemine or Halofuginone?

Alkaloid compounds often fall under controlled‑substance or dual‑use regulations in some jurisdictions. Importers should verify national import licences, check the product’s classification under the UN Convention on Certain Conventional Weapons, and ensure that the supplier provides the necessary export documentation and end‑use declarations.
