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.

tamarind-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.

Yes. Top supports customization and OEM / private-label:Grade — standard vs a defined target gradeSupply at a defined concentration for easier handlingPrivate-label with your artwork and documentsDevelop a dedicated lot to Q/XXXX or your spec.MOQ and lead time depend on customization; tell us the target grade, pack size and volume and we will quote. All customized lots still ship with COA plus assay plus MSDS.

Country of OriginGuangxi cultivated areas, China (and imported from Southeast Asia).Top keeps a raw-material (lot) -> processing -> concentration/purification -> packaging ledger and can issue a lot-specific traceability dossier. For audit, Top provides the supply-chain statement, batch COA and assay.Traceability traces the the raw-material orchard / lot through processing to the finished product.

Primary ApplicationsFlavour, fragrance and functional-food / health-product formulations.It is used as a flavour / fragrance material, dosed per formulation. Formulators label it as the product (species) extract and note it is distinct from a generic essential oil (species-specific extract).Cosmetic use follows the Cosmetic Safety Technical Specification and EU 1223/2009; safety assessment applies.

Yes. For B2B orders Top can sign a sales contract and, for ongoing supply, a quality agreement / LTA specifying grade, pack sizes, price mechanism, lead time, traceability and complaint handling.For tamarind-concrete, Q/XXXX conformance is the working acceptance basis unless the contract states otherwise (the COA and assay accompanying each lot are the evidence). We encourage buyers to attach their specification so both sides measure against the same numbers.Contracts are in EN/CN as needed.
