FAQ Header
Do you sign a contract or quality agreement?
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 green-plum-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.

How do you handle a quality complaint or dispute?
Top treats complaints seriously:Notify us within the validity window with the lot number, COA reference and the issueWe review the retained sample and the batch COA / assay resultIf a genuine non-conformance is confirmed, we offer replacement, credit or refund per the contractFor disputes we can involve a third-party lab (SGS, Eurofins) with costs allocated by outcome.Keep the original pack sealed where possible. Our aim is a fair, documented resolution — we do not argue against our own lot data.

What botanical species does Green Plum Concrete come from, and where is it sourced?
green-plum-concrete from Top is the concentrated aqueous/alcoholic extract of green plum (Prunus mume) fruit — a sour, fruity concrete, not a distilled oil. Top declares the botanical name on every COA.Origin is Guangxi cultivated orchards, China. Plum (Prunus mume, as smoked Chinese dark plum) is on China's medicine-food dual-use list; green-plum products are ordinary food raw materials in China. Top keeps the species + origin declaration so the identity is traceable. Because it is a fruit extract (not a distilled oil), it is labelled and used as a fruit concrete / extract, not an essential oil; the sourness comes from...

Do you supply diluted or blend-ready green-plum-concrete?
Top can supply pre-blended (defined ratio in a food-grade carrier) or pre-diluted forms for easier handling and lower-cost trials. Blend base and concentration are agreed per order and stated on the COA.Note that blending changes the measured specification window, so the COA always declares the actual concentration and base. Neat lots remain the default for buyers who formulate in-house.

How do you ensure batch-to-batch consistency and traceability?
Top controls consistency through Q/XXXX and per-batch QC matched to the reference profile. Traceability runs raw-material source through processing to the finished product with a lot-specific ledger and retention sample.If your application needs tight tolerances, tell Top and we can select lots from the same source or blend to a target profile. Every shipment carries a lot number linking to the COA and assay on file.
