Buyer Due Diligence
Quality, Documentation & Supplier Control
Transparent answers to the questions B2B buyers ask before placing ingredient orders. AICHENGFU® operates as a UK-based sourcing platform and is committed to supporting your due diligence process honestly and professionally.
A UK-Based B2B Functional Ingredients Platform
AICHENGFU® is the functional ingredients business of Lumen Star Group Ltd, registered in England and Wales (Company No. 17045222). This website, aichengfu.uk, is operated by Lumen Star Group Ltd and serves B2B buyers globally.
We operate as a sourcing and supply chain coordination platform. This means we work with selected manufacturing and export partners — primarily across Asia — to source and supply functional ingredients matched to your specification, market and application.
We are not a consumer retail supplement store and do not sell finished supplements directly to end consumers. Our customers are ingredient buyers: supplement manufacturers, functional food and beverage brands, contract manufacturers and personal care formulators.

Selected Manufacturing Partner Network
AICHENGFU® does not rely on a single factory model. Instead, we work with selected manufacturing and export partners across key ingredient categories. This allows buyers to access suitable production sources, documentation support and flexible sourcing options based on specification, target market and volume.
We do not represent that AICHENGFU itself holds manufacturing certifications such as HACCP, ISO 22000, HALAL or KOSHER. These certifications are held by the manufacturing partners we work with, and their availability depends on the specific product and source.
When you specify your certification requirements, we confirm which partners and products can meet them before providing a quotation.
Manufacturing source information may be discussed on a project basis, subject to product category, confidentiality requirements and supplier agreement.
Which countries do your manufacturing partners operate in?
Primarily China, with specific products sourced from India, Japan and other Asian markets depending on ingredient category and specification.
Can buyers visit or audit manufacturing facilities?
Factory visits and audits can be discussed depending on the product, order scale and manufacturing partner. Please raise this requirement early in the sourcing process.
How does AICHENGFU select its manufacturing partners?
Partners are selected based on product quality, certification status, export experience, documentation capability and their ability to meet buyer specifications consistently.
Partner Qualification
Supplier Qualification Framework
Before working with a manufacturing or export partner, AICHENGFU applies a structured qualification process. This is not a guarantee of compliance in your target market — it is part of our internal sourcing discipline and buyer due diligence support.
Supplier Registration Review
Business registration, export licence and company background review before engagement.
Factory Certificate Review
Review of available certifications — HACCP, ISO 22000, HALAL, KOSHER or Organic — held by the manufacturing partner.
Product Specification Review
Technical specification, assay method, grade, form and typical analysis reviewed against buyer requirements.
COA and Batch File Check
Recent Certificate of Analysis and batch documentation reviewed for completeness and consistency.
Allergen / GMO / Origin Documentation Check
Allergen statement, non-GMO declaration and origin documentation reviewed where applicable.
Sample Confirmation
Reference samples reviewed or buyer sample requested to confirm material quality before commitment.
Third-Party Testing Discussion
Options for independent laboratory verification discussed based on buyer requirements and product category.
Trial Order Before Bulk Supply
Where appropriate, a trial order is recommended before committing to full bulk supply quantities.
Batch Consistency Review
Ongoing batch consistency monitored through COA review and buyer feedback across repeat orders.
This qualification framework supports AICHENGFU's internal sourcing process and buyer due diligence support. It does not constitute a guarantee of regulatory compliance in any specific market. Buyers retain full responsibility for their own regulatory assessment.
Step-by-Step Process
Sample, Testing and Trial Order Workflow
AICHENGFU encourages buyers to validate ingredients through samples and trial orders before committing to bulk supply. The workflow below outlines the typical process.
Buyer Sends SPEC + Market + Volume
Share your required specification, target market and estimated order volume. This allows AICHENGFU to identify the most suitable grade and manufacturing source.
AICHENGFU Recommends Suitable Grade
We review your requirements against available grades and sources, then recommend the most appropriate option with indicative documentation and pricing.
Documentation Availability Checked
We confirm which documents are available for the recommended grade and source — COA, TDS, MSDS, allergen, certification — before proceeding.
Sample Request Discussed
Sample availability, quantity and any applicable sample cost are confirmed. Samples are dispatched with relevant documentation.
Buyer May Arrange Third-Party Testing
Buyers are encouraged to use their own approved laboratory to verify the sample. AICHENGFU can also discuss third-party testing options on request.
Trial Order Before Bulk Supply
A trial order can be discussed before committing to bulk supply. Trial terms, lead time and packaging are agreed based on product and volume.
Third-party testing: If you require independent laboratory verification, please state this clearly when submitting your inquiry. AICHENGFU can discuss options based on your requirements and the product in question. Testing arrangements and cost are agreed on a case-by-case basis.
What Buyers Should Check Before Bulk Orders
Use this checklist to prepare your sourcing inquiry. Providing these details upfront allows AICHENGFU to respond with the most relevant grade, documentation and pricing.
How to Request Ingredient Support
The most efficient way to get a response from AICHENGFU is to send SPEC + Market + Volume. This gives us what we need to recommend the right grade, confirm document availability, advise on lead time and provide accurate pricing.
Your required specification — assay, grade, form, purity, particle size
Your target market — UK, EU, USA, Australia or other — this affects documentation and labelling
Your estimated order quantity — sample, trial or bulk — this affects MOQ and pricing
