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 cert copies), formulation advice (melting/dilution in carrier oil or food-grade ethanol, grade selection for stability, food vs cosmetic labeling, oxidation-control note for this waxy, aroma-sensitive concrete) 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.
