What a usable certificate contains
Producer and site identification, the exact lot or batch reference, production date, sampling date and plan, each parameter with its analytical method and result, the laboratory that performed the work, and an authorised signature. Anything missing narrows what the document can support in a dispute.
Typical values are not results
Documents headed 'typical analysis' describe a product family, not the cargo in front of you. They are useful for formulation planning and useless for acceptance decisions and claims.
Tie the certificate to the delivered lot
The lot number on the certificate must match the marks on the delivered cargo or the bulk parcel identification. Without traceable linkage, the certificate cannot be attributed to what arrived.

자주 묻는 질문
Is a supplier's in-house laboratory acceptable?
It can be, when the laboratory participates in proficiency testing and the parameters are non-critical. For safety parameters and high-value contracts, independent accredited verification is the stronger position.

Sampling is the largest source of error in feed-ingredient testing; a valid result requires many small increments combined into a representative composite, taken to a written plan.
Independent verification means testing the delivered lot at an accredited third-party laboratory using the contractual reference methods, on a properly drawn and retained sample.
Traceability is the documented ability to follow a material one step back and one step forward through the chain, and it is what makes a targeted recall possible instead of a total one.
