Top uses solvent (petroleum ether / ethanol) extraction of fresh flowers, followed by solvent recovery and concentration to a concrete. Top documents the process and the yield.Top controls the benzyl-ester/linalool profile through the source flower and the extraction step.

Top issues the full export set: commercial invoice, packing list, certificate of origin, bill of lading / airway bill, COA (Q/XXXX conformance stated), assay report, MSDS/SDS, and health / phytosanitary certificate (on request). We prepare documents to meet your customs format and HS code, and reference Q/XXXX and the product standards as the basis.If your market needs extra certificates, tell Top in advance. We cooperate with your broker for smooth clearance.

michelia-alba-concrete is a low-hazard material and is not classified as dangerous goods in standard carriage regimes — low DG friction. That said, Top still issues an SDS (CLP for EU) and packs it sealed and correctly labelled; if a carrier treats it as a DG under a stricter interpretation, we declare and pack to the SDS-driven class and use qualified forwarders.We never misdeclare; the lot-specific SDS drives the transport class. Buyers should inform their broker of the material and SDS so clearance and last-mile handling are correct.
