Six-step evidence workflow
1Define the application
Identify the product line, intended use, site, buyer objective and person responsible for the decision.
2Record the baseline
Capture the relevant conditions and measurements before the product is applied.
3Agree on the protocol
Record product identity, sample or batch reference, amount, timing, application method, comparison and controls.
4Define success criteria
Choose the observable or measured indicators and decision rules before seeing the result.
5Document execution
Keep dated records of application, observations, analytical results and any deviations from the plan.
6Review before scale-up
Compare results with the baseline, identify limitations and confirm technical, commercial and destination-country requirements.
Frequently asked questions
Why should buyers define a trial before placing a bulk order?
A defined trial creates a shared baseline, application record and acceptance criteria. It helps the buyer and supplier separate observations from assumptions before a commercial decision.
Can one trial method be used for aquaculture products and industrial enzymes?
No. Aquaculture trials depend on species, pond conditions, culture stage and farm management. Industrial enzyme trials depend on wastewater source, process flow, operating conditions and measurable treatment targets.
What should be recorded before an aquaculture product trial?
Record the species, culture stage, pond type and area, water conditions or test results, feeding and aeration status, recent treatments, target problem and selected comparison method.
What should be recorded before an industrial compound enzyme trial?
Record the industry and wastewater source, process flow, daily volume, operating pH and temperature where relevant, recent baseline data, current treatment inputs, target indicators and sampling method.
Does a positive sample trial guarantee the same result at every site?
No. A trial result belongs to its recorded conditions. Scale-up, season, operating practices, water characteristics and other variables can change the result.
What evidence should an international distributor retain?
Retain the product identity, batch or sample reference, trial plan, baseline, application record, dated observations, test results, deviations, photos where appropriate, buyer feedback and final decision.
