Use this product specification framework to prepare a clearer RFQ, compare supply options and reduce avoidable changes between sampling, quotation and shipment.
Core principle: The specification defines agreed requirements. The COA records results for a tested sample or lot.

Building an ingredient specification
A specification is the agreed definition of what “acceptable” means for a product. It turns a vague expectation into measurable acceptance criteria that a supplier can meet and a lab can test against. A good specification is complete enough to protect the application, but not so tight that it creates cost and rejections without benefit.
Specification structure
A strong specification usually includes:
- legal and commercial product name;
- botanical identity where relevant;
- origin and variety if mandatory;
- physical form, particle size, grade or count;
- appearance, colour, aroma and taste;
- moisture, purity and foreign matter;
- microbiological limits;
- residues, heavy metals and mycotoxins where relevant;
- allergen and cross-contact status;
- processing or treatment status;
- packaging, shelf life and storage;
- sampling, test methods and acceptance rules.
Selecting parameters
Choose parameters that matter to your application and market, and mark each as mandatory, preferred or informational. Testing everything to the tightest limit is expensive and slows qualification; focus the mandatory limits on the real hazards and functional needs.
Realistic tolerances
Agricultural ingredients vary by crop and season, so tolerances must be realistic. Overly narrow cosmetic limits can cause avoidable rejections and cost without improving performance. Set limits against what the application actually needs and what a good crop can consistently deliver.
Specification versus COA
A specification defines the acceptance criteria; a certificate of analysis reports what a sample measured against them. Keep the two distinct: a COA is not a substitute for an agreed specification.
