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 yellow-chrysanthemum-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.

Top treats complaints seriously: (1) notify us within the validity window with the lot number, COA reference and the issue; (2) we review the retained sample and the batch COA / assay result; (3) if a genuine non-conformance is confirmed, we offer replacement, credit or refund per the contract; (4) for 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.

Every Top order ships with: (1) COA (batch-specific, conforming to Q/XXXX — flavonoid content, solvent residue (GB 5009.262), heavy metals and micro); (2) assay report (key markers + heavy metals + microbiology + sensory); (3) MSDS / SDS (CLP for EU) where applicable; (4) commercial invoice plus packing list; (5) certificate of origin; (6) health / phytosanitary certificate on request; (7) food-use note for food buyers. Optional third-party test (SGS, Eurofins) at buyer cost. All documents in EN (and CN on request).

No. Chrysanthemum indicum L. (wild chrysanthemum) is not CITES-listed (cultivated/processed source) — no CITES permit required. Top ships the standard food/export documents. Normal food-safety regulation applies; no CITES hurdle exists for yellow-chrysanthemum-concrete.

Top can provide: ISO 9001 (quality management), Halal and Kosher certificates (on request), organic for dedicated lots (on request), a non-GMO declaration, certificate of origin, and a health / phytosanitary certificate for food import on request. For EU we supply CLP-format SDS; for the US we reference 21 CFR food frameworks. Third-party test reports (SGS, Eurofins) at buyer cost. Confirm available certificates at order time — some are per-lot / per-request rather than blanket.

yellow-chrysanthemum-concrete from Top is the concrete obtained by solvent extraction of Chrysanthemum indicum flowers — a greenish-yellow, bitter-herbal floral concrete, not a distilled oil. Top declares the botanical name on every COA. Origin is Guangxi wild-cultivated areas, China. Chrysanthemum indicum is recorded in the Chinese Pharmacopoeia as a herbal material; it is positioned as an herbal/fragrance raw material rather than a standard food flavour. Top keeps the species + origin declaration so the identity is traceable. Because it is a solvent concrete (not a distilled oil), it is labelled and used as a concrete/extract, not an essential oil.
