What after-sales support do you provide?

Top provides ongoing support: lot traceability and re-test within shelf life using the retention sample, documentation re-issue (COA / SDS / origin / health / phytosanitary cert copies), formulation advice and a responsive complaint channel. For LTA buyers we assign a dedicated contact and periodic review of grade consistency.

We treat the relationship as long-term — the after-sales step is where we protect your production continuity, not an afterthought.
