从China供应商批量进口30% Wps Propolis Liquid Extract 2 Years
Sourcing 30% WPS Propolis Liquid Extract 2 Years from Henan Super-sweet Biotechnology Co., Ltd - China Import Guide
Before ordering, verify that Henan Super-sweet holds valid manufacturing licences for the intended application of the propolis extract. If the product is for food or dietary supplement use, confirm compliance with your country's novel food or GRAS status, as propolis regulatory classification varies by jurisdiction. Request a complete certificate of analysis for a recent batch, including sensory evaluation, physicochemical parameters, microbial load, heavy metals, and pesticide residues. Validate any ISO or SGS certification directly with the issuing body using certificate numbers, rather than accepting copies at face value.
Shipping liquid extracts internationally requires attention to hazard classification, as ethanol-based products may be classified as dangerous goods depending on concentration and flash point. Confirm the exact formulation with the supplier, obtain the safety data sheet (SDS), and verify whether your freight forwarder can handle the material under IATA or IMDG regulations. Lead times, production scheduling, and payment structures are not disclosed in the listing and must be negotiated. For a first order, consider starting with the advertised free sample, followed by a small trial batch to assess batch-to-batch consistency before committing to volume.
Upon receipt, inspect packaging integrity for leakage, corrosion, or seal compromise. Verify that batch numbers on containers match the certificate of analysis and that manufacturing dates align with the claimed two-year shelf life. Conduct organoleptic assessment (colour, odour, taste if applicable) against the sample previously approved. For quality-critical applications, arrange independent third-party testing for flavonoid content, residual solvent, and microbial load at a laboratory accredited to ISO 17025. Document all discrepancies immediately and withhold final payment until resolution. Maintain cold, dark storage conditions even if the product is ambient-stable, to maximise retention of bioactive compounds throughout the declared shelf life.
