Its SEAWINNER organic fertilizers are also stated to be certified by ECOCERT as organic agricultural inputs under both EU and NOP standards, providing explicit evidence of multiple quality, environmental, occupational-safety, and product certifications.

Its agronomist team provides professional fertilizer solutions and crop-protection advice, indicating technical development capability, although the slices do not provide specific R&D projects, patents, laboratories, or newly developed products.
