Yes. G4S welcomes factory audits and visits (virtual or on-site) for qualified B2B buyers — covering the processing line, QC lab, packaging and traceability. We can show the raw-material sourcing and the Q/XXXX conformance documentation. Audit requests should be made in advance so we prepare the line, documents and (where needed) an NDA. A successful audit builds the basis for an LTA and better pricing.

G4S uses cold-pressing of the fresh peel (for CFPA-type oil) or steam distillation of the peel. G4S documents the process and the yield. G4S controls the limonene / nootkatone profile through the source pomelo variety and the processing method.

G4S 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 G4S in advance. We cooperate with your broker for smooth clearance.

pomelo-oil is a low-hazard material and is not classified as dangerous goods in standard carriage regimes — low DG friction. That said, G4S 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. 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.

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.
