Documentation to request per batch
Use this checklist when qualifying a new ingredient or supplier. Every item below is part of the documentation package we provide to support ingredient qualification, formulation and supplier audits.
- COA per batch — batch-specific Certificate of Analysis stating the assay result and method.
- TDS / MSDS — technical and safety data sheets for handling, storage and regulatory files.
- HPLC or UV assay — marker-compound content verified by a stated, appropriate method.
- Heavy metals — ICP-MS panel (e.g. lead, arsenic, cadmium, mercury).
- Microbiology — total plate count, yeast & mould, and pathogen screening.
- Pesticide residue — where applicable to the botanical and target market.
- Residual solvents — where applicable to the extraction process.
- Third-party testing — available on request when your market requires independent verification.
Specification questions to ask
- What is the marker compound and the assay method used to verify it?
- Is the stated percentage a minimum specification or a typical value?
- What are the MOQ, lead time and sample availability for this specification?
- How is batch-to-batch consistency controlled, and can you see historical COAs?
- Which quality-system certifications apply to this product?
