In short: Hunan Tea Group Co., Ltd. operates a final packing and refining processing facility in Changsha, China, handling green, oolong, and black teas under Ethical Tea Partnership certification.
Hunan Tea Group Co., Ltd. operates a final packing and refining processing facility in Changsha, the capital of Hunan province in south-central China. Located at an elevation of 47 metres, this is a processing and packing operation rather than a primary cultivation estate, handling green, oolong, and black teas. The facility is certified by the Ethical Tea Partnership, though no specific downstream buyers are recorded in available supply-chain data.
Terroir & Climate
At 47 metres elevation in the Xiang River valley, Changsha occupies a humid subtropical zone characterised by hot, wet summers and mild winters. Facilities at this low altitude in Hunan typically benefit from proximity to river transport and urban infrastructure rather than the cool, slow-growing conditions that define high-elevation tea cultivation. The region's climate—annual rainfall exceeding 1,400 millimetres and mean temperatures around 17°C—supports year-round processing operations, though the character of the finished tea depends primarily on the provenance of incoming leaf rather than local terroir.
Hunan province is historically significant in Chinese tea production, with cultivation concentrated in higher elevations to the west and south of Changsha. Processing facilities in the capital tend to serve as aggregation and finishing points for leaf grown elsewhere in the province. The low elevation and urban setting suggest this operation's role is refining, blending, sorting, and packing rather than primary manufacture from fresh leaf.
Tea Produced
The facility processes green, oolong, and black teas, reflecting the stylistic diversity of Hunan's production. Green teas from the province often exhibit a rounded, mellow character with nutty or chestnut notes, particularly when pan-fired in the traditional manner. Hunan oolongs tend toward lighter oxidation, yielding floral or orchid-like aromatics, while black teas from the region can show malt, cocoa, and a gentle astringency. As a refining and packing operation, the final cup profile will depend on the origin and initial processing of the leaf received, though Changsha's infrastructure allows for precise grading and blending to meet export and domestic specifications.
Operator
Hunan Tea Group Co., Ltd. operates this final packing and refining facility in Changsha. No additional estates or processing centres operated by the same company are recorded in available supply-chain directories, suggesting this may be the group's principal or sole recorded processing site.
Certifications & Ethics
The facility holds certification from the Ethical Tea Partnership (ETP), a multi-stakeholder initiative that monitors labour standards, environmental practice, and community welfare across tea supply chains. ETP certification requires annual on-site audits against a common standard, with a focus on continuous improvement in working conditions, pesticide management, and smallholder livelihoods. For buyers, the certification provides third-party assurance that the operation meets baseline ethical criteria; for workers and surrounding communities, it signals a commitment to measurable social and environmental accountability.
