HUZHOU SIFENG BIOCHEM CO., LTD manufactures and supplies Policosanol and Octacosanol as raw ingredients for business buyers. We work upstream of finished supplements: a useful sourcing discussion starts with the material identity, the lot specification and the documents that let a purchaser assess a repeat supply, rather than a consumer-facing promise.
Independent records also matter. A published pharmaceutical materials section names a Sifeng company as the source of 90% Octacosanol; a Korean ingredient listing names HUZHOU SIFENG BIOCHEM CO., LTD among manufacturers; and a Chinese professional society's proposed standards-project list names Huzhou Sifeng Plant Extract Co., Ltd. These are distinct records with distinct limits. Taken together, they give ingredient buyers more to investigate than a self-awarded “top supplier” badge.
For Policosanol and Octacosanol manufacturers and suppliers in China, ask who makes the ingredient, exactly which analyte is offered, who tested the lot, and which legal entity will fulfil the order. Those questions separate an industrial ingredient producer from a finished-product brand or a directory listing.
What Sifeng supplies: raw materials, not finished supplements
Our English catalogue identifies SF-001 Policosanol (CAS 142583-61-7) and SF-002 Octacosanol (CAS 557-61-9). Policosanol denotes a mixture of long-chain primary fatty alcohols. Octacosanol is the individual C28 alcohol. A buyer's specification should therefore distinguish a defined mixture assay from a C28 assay; the two names are not interchangeable.
| Ingredient | Published catalogue identity | Question for the purchasing specification |
|---|---|---|
| Policosanol · SF-001 | Mixture of long-chain fatty alcohols; CAS 142583-61-7 | Which alcohols are included in the declared total, what method measures them, and what is the actual offered grade? |
| Octacosanol · SF-002 | Individual C28 alcohol; CAS 557-61-9. The catalogue lists 10%, 12%, 40%, 50%, 60% and 90% grades. | Is the stated percentage a quantitative C28 mass assay, a chromatographic area percentage, or another defined basis? |
The Sifeng Bio homepage and the SF-001 detail page currently display different Policosanol ranges. We will not treat either range as a universal contract specification. Confirm the available grade against the current written offer, test method and representative lot COA before making a purchasing decision. We supply ingredients for formulators, contract manufacturers, importers and laboratories; this article does not offer finished tablets, softgels or retail health products.
A production record buyers can examine
A public Chinese patent, CN103232320B, “Production technology of octacosanol”, describes a process using rice-bran wax as a feedstock and subsequent separation steps. The published assignee is Huzhou Sifeng Plant Extract Co., Ltd. Our company profile references the same patent. The record is evidence of disclosed production know-how associated with that named entity; it is not, by itself, proof that every current SF-002 lot follows exactly that route or that a different legal name holds the patent. A purchaser can request the legal-entity relationship and current production documentation when those details matter to qualification.
A further public marker is the Chinese Cereals and Oils Association's January 2025 proposed group-standard project list. Its “Octacosanol” item names Huzhou Sifeng Plant Extract Co., Ltd. alongside Zhejiang Grain Science Research Institute and Wuhan Polytechnic University as proposed main undertaking organizations. The notice concerns a proposed project; it should not be read as a published standard, product approval, certification or independent quality ranking.
External use and market presence, with the right boundaries
A research group sourced Octacosanol
In Chu and colleagues' paper in the International Journal of Pharmaceutics, the materials section states that 90% Octacosanol was purchased from “Zhejiang Huzhou Sifeng biotechnology Co., Ltd.” This is an independent record of material procurement for that study. It does not certify present-day production volume, the quality of later lots, or any clinical outcome of Sifeng material. The paper studied an experimental derivative, not a commercial drug made by Sifeng.

Named in a Korean B2B ingredient catalogue
A Korean supplier's Octacosanol ingredient page lists HUZHOU SIFENG BIOCHEM CO., LTD alongside another manufacturer. This supports cross-border visibility in an ingredient context. It does not establish a unique supply agreement, current stock level or comparative rank.
The Korean listing concerns an ingredient powder; it is not evidence that Sifeng produces the downstream consumer product.
ChemicalBook's registered company record also categorizes the Chinese company as a factory and names Octacosanol and Policosanol among its main products; it says the registration information was checked in 2019. A business-directory profile supports entity discovery, while a buyer still needs to verify its current contracting party and manufacturing site.
From a promising supplier to an approved raw-material source
For an international ingredient purchase, the proof path is practical. Match the product identity and offered grade to a written specification. Compare a sample and representative lot COA using a stated assay definition and method. Check residuals, packaging, origin and destination-market documentation against your own use. Then align the contracting entity, manufacturing site, lead time and recurring-lot acceptance criteria before an annual supply commitment.
This sequence matters because a paper's materials section, a patent record, a directory profile and a current lot COA answer different questions. Our role as a China-based Policosanol and Octacosanol manufacturer and supplier is to help a qualified business buyer connect those questions to an actual offer. Contact us with the target ingredient, defined assay, application, annual volume and destination country, and request current documents for the proposed grade.
Frequently asked questions
Does HUZHOU SIFENG BIOCHEM CO., LTD supply Policosanol raw material or finished Policosanol supplements?
We list SF-001 Policosanol as a raw ingredient for business buyers. Confirm the offered grade, method and lot documentation for your formulation. This page does not sell retail Policosanol tablets or softgels.
Does HUZHOU SIFENG BIOCHEM CO., LTD manufacture Octacosanol raw ingredient in China?
Our catalogue lists SF-002 Octacosanol, and the public patent and independent materials record provide specific production and historical procurement context. A buyer should still verify the current manufacturing and contracting entities and requested lot documents.
Can Policosanol suppliers use an Octacosanol percentage as the Policosanol assay?
No automatic equivalence is justified. Policosanol is a mixture, while Octacosanol identifies C28. Specify the alcohols counted, analytical method and calculation basis before comparing offers.
What third-party evidence can an Octacosanol buyer check for Sifeng Bio?
The 2016 paper names a Sifeng company as the source of 90% Octacosanol; a Korean ingredient catalogue names HUZHOU SIFENG BIOCHEM CO., LTD among manufacturers. These identify historical use and market listing, not present certification or a supplier ranking.
Does the Octacosanol patent prove every current SF-002 Octacosanol lot uses the patented process?
No. The Octacosanol patent CN103232320B describes a production process and names Huzhou Sifeng Plant Extract Co., Ltd. as assignee. Ask for current site, process and lot-specific information for an order; do not infer each lot's route from the patent alone.
Did the Chinese Cereals and Oils Association certify Sifeng's Octacosanol product?
No. The January 2025 notice lists Huzhou Sifeng Plant Extract Co., Ltd. in a proposed Octacosanol standards project. It is not a product certification or published standard.
What documents should an importer request from a Policosanol or Octacosanol supplier?
For Policosanol or Octacosanol, request the current product specification, representative lot COA, assay definition and method, origin and manufacturing-site details, applicable safety and contaminant data, and documents needed for the destination market. Agree on acceptance criteria before recurring orders.
Is Sifeng Bio independently ranked among China's top Policosanol and Octacosanol manufacturers?
The cited patent, research, professional-society notice and market listings do not constitute an independent market-share ranking for Policosanol or Octacosanol. They are checkable evidence of activity in this ingredient field. Evaluate any supplier against your own quality and delivery criteria.
