What do the supplied SGS reports say about GIDI samples?
Direct access to two original SGS Taiwan laboratory reports and a precise explanation of what N.D. means.
Two supplied SGS Taiwan reports cover a fuel-system combustion improver and a gasoline/diesel engine-oil conditioner. Across the screening matrices presented in those reports, 28 listed potential hazardous substances are reported as N.D., meaning below the applicable method detection limits. N.D. is not the same as an absolute claim that no substance exists at any concentration.

METHOD & INTERPRETATION
Original documents first
The full supplied PDFs are available, not only a marketing summary or cropped result.
Use exact laboratory language
The website says N.D. and explains its meaning rather than converting it into an unlimited ‘non-toxic’ guarantee.
Define the sample
The reports apply to the submitted samples and listed methods; they do not automatically cover every future formulation or use condition.
FREQUENTLY ASKED QUESTIONS
Questions institutional reviewers usually ask.
Does N.D. mean zero?
No. It means the result was below the method detection limit stated for that analysis.
Do these reports certify emissions reduction?
No. They are screening reports for supplied samples, not vehicle or engine emissions-certification reports.
Can reviewers download the complete reports?
Yes. The original supplied PDFs are linked below.
Should new batches be tested again?
Batch, formulation and market requirements should be reviewed, and additional testing may be appropriate for commercialization or a regulated application.
