How do you ensure batch-to-batch consistency?

Question

Accepted Answer

Every batch is GC-MS checked against ISO 3515 and GB/T 12653-2008 limits before release, and we blend within a narrow linalool/linalyl acetate window so your formula stays stable order after order.

If a batch drifts toward a boundary, we flag it in the COA before you order — never after.Send us your acceptable spec window and we will confirm we can hold it across your order program.
