Can you customize specifications or provide OEM / private-label?
Yes. G4S supports customization and OEM / private-label: (1) grade — standard vs a defined target grade; (2) supply at a defined concentration for easier handling; (3) private-label with your artwork and documents; (4) develop 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.
What is the country of origin, and can you provide traceability?
Country of origin: Guangdong / Fujian / Hainan / Guangxi cultivated orchards, China. G4S keeps a raw-material (lot) -> processing -> concentration/purification -> packaging ledger and can issue a lot-specific traceability dossier. For audit, G4S provides the supply-chain statement, batch COA and assay. Traceability traces the the raw-material orchard / lot through processing to the finished product.
What are the main applications of pomelo-oil?
Primary applications: flavour, 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.
Do you sign a contract or quality agreement?
Yes. For B2B orders G4S 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 pomelo-oil, 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?
G4S 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.
What documents (COA, assay, MSDS) ship with each order?
Every G4S order ships with: (1) COA (batch-specific, conforming to Q/XXXX — relative density, refractive index, optical rotation, aldehyde content, 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).
Is pomelo-oil subject to CITES controls?
No. Citrus grandis (L.) Osbeck (pomelo) is not CITES-listed (cultivated/processed source) — no CITES permit required. G4S ships the standard food/export documents. Normal food-safety regulation applies; no CITES hurdle exists for pomelo-oil.
What certificates and accreditations can you provide?
G4S 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.
What botanical species does yuzu oil come from, and where is it sourced?
pomelo-oil from G4S is the essential oil of pomelo (Citrus grandis) peel — a bright, fresh citrus oil obtained by cold-press or steam distillation, distinct from distilled lemon or orange oils. G4S declares the botanical name on every COA. Origin is Guangdong / Fujian / Hainan / Guangxi cultivated orchards, China. Pomelo is a standard food ingredient; pomelo peel oil is a food-grade citrus flavour under GB 2760 and relevant citrus frameworks. G4S keeps the species + origin declaration so the identity is traceable. As a true essential oil it is labelled and used as such; cold-pressed (CFPA) oil retains...
