Every batch is tested against these limits and the results are printed on the COA, giving your QC a fast pass/fail gate before goods are released. Values slightly outside the typical window trigger re-blending or rejection, so the oil you receive is always within the certified range.

Send us your in-house specification sheet and we will confirm alignment or adjust the acceptance window before you place the order.
