Quick answer
An in-house blend is managed as a compound ingredient, and the file must cover every component, not only the trade name. A Ningbo ingredients maker includes ratio ranges, origin statements and certificates per component, carriers and anti-caking aids, cleaning notes, coding rules and retention samples. For export filings the blend is a separate item with a breakdown table; any component change triggers a file update.
Detailed explanation
Minimum file contents
- Blend name, model and formula ratio ranges
- Chemical name, supplier, grade and origin type of every component
- Halal certificates and origin statements for all components
- Process, mixing equipment, cleaning and shared-line notes
- Batch-coding rules, inspection standards and retention records
High-risk components first
Gelatin, stearates, glycerol, emulsifiers, enzymes, fragrance solvents, capsule materials and collagen are listed separately even at low dosage; a small share is no reason to merge them.
Version control
Give the file a version number and effective date; run internal review before releasing formula, ratio or supplier changes, and archive old versions so any batch maps to its version.
External submission
File a blend breakdown table and an index mapping single components to certificates; for confidential formulas, agree a disclosure format with the reviewer, but never refuse to state origin types.
