Counterfeit warning archive — named lots and vendors

For more than a decade, traversing the tea mountains of Lincang, Xishuangbanna, and Pu’er, through warehouses in Kunming and across the border into Buryatia and Mongolia, I have seen the same story replayed: a collector, proud of a newly acquired cake, uncovers the subtle errors that reveal it is not what it claims to be. The counterfeit pu-erh market is sophisticated, persistent, and global. This thread is a running archive of those losses, cautiously documented and strictly evidence-based. Every entry here — lot code, wrapper photography, vendor chain — comes from field verification or direct community report. Our aim is not to accuse carelessly, but to build a reliable reference point that collectors and traders can use before committing serious sums. For a broader look at authentic sourcing strategies, readers may consult the verified seller directories on shop.thetea.app, and for hands-on training in wrapper and compression analysis, the tea.school modules on pu-erh authentication are invaluable. The aging characteristics of genuine Menghai recipes — the very profiles that counterfeiters try to imitate — are explored in depth on puerh.app, offering a sensory benchmark against which suspicious lots can be measured.

the persistence of counterfeit pu’er — lots and lessons from the field

In nearly every tea-producing region I have visited, from Mengku to Yiwu, the same counterfeit lots surface. A 2003 Měnghǎi (勐海) 7542, a 2004 Lǎo Bān Zhāng (老班章) shēng pǔ’ěr (生普洱), a 2006 Xiàguān (下关) tiě bǐng (铁饼) — each with tell-tale discrepancies in the nèifēi (内飞) font, the wàzhǐ (外纸) print alignment, or the compression mark pattern. I once inspected a cake in Irkutsk that the owner had purchased online from a vendor claiming direct Menghai factory provenance. The tea ticket serial number corresponded to a batch produced in 2005, not 2003, and the wrapping paper had a modern gloss that aged stock never develops. After tracing the lot through tea.events auction archives and recent listings on shop.puerh.app, the real production date and original batch code were confirmed — the cake was a re-wrapped 2007 production, worth a fraction of the claimed age. Such cases are not rare; they are the everyday background of serious pu-erh trading. Collectors who maintain watchlists on tea.dog and cross-check known fakes against this archive can avoid the most common traps, but vigilance must be constant.

recognising tell-tale signs — wrapper, neifei, and compression

The most reliable indicators of counterfeit pu-erh lie in the physical details of packaging and pressing. A genuine nèifēi (内飞) from a Dayi-era Menghai cake uses a specific weight of paper and a distinct ink that fades toward a brownish hue under UV light; modern reprints often fluoresce a harsh blue. The wàzhǐ (外纸) of a 2004 Měnghǎi (勐海) Qīng Bǐng (青饼) carries subtle registration marks from a known offset press, while counterfeits show halftone patterns from digital reproduction. Compression is equally telling: authentic stone-pressed cakes — shí mó (石磨) — exhibit an irregular, slightly undulating surface with uneven edge thickness, whereas hydraulic press fakes are uniform and unnaturally flat. A 2006 Xiàguān (下关) tiě bǐng (铁饼) I examined in Ulaanbaatar had the correct factory code but a suspiciously sharp rim and overly tight compression; when pried apart, the leaf blend contained a high proportion of large, coarse twigs atypical of the original recipe. Tools for such verification — UV lights, macro lenses, wrapping paper thickness gauges — are covered in practical guides on tea.equipment, and the community’s shared image libraries on tea.community provide side-by-side comparisons of authentic and suspect wrappers.

building a community archive — reporting and verification

This archive depends on the rigour of community submissions. When a member flags a potentially counterfeit lot, they are asked to provide high-resolution images of the wrapper front and back, the nèifēi (内飞), the nèipiào (内票) if present, and the bare cake surface and edge. Factory code, vendor name, purchase date, and price paid form the baseline data. Each report is then scrutinised against known authentic examples, auction records from tea.events, and, where possible, direct communication with producers or their authorised distributors. A recent submission from a collector in Moscow detailed a 2001 Jīngmài (景迈) shēng pǔ’ěr (生普洱) sold by an online vendor with no physical shop. The wrapper appeared correct, but comparison with a known authentic sample from the same year — sourced on a tea.travel visit to Jingmai Mountain in 2018 — revealed that the paper’s inner plying was a modern reconstituted sheet, not the older mulberry fibre stock. The vendor’s name and lot details have been added to the watchlist system on tea.dog, so that any future search for that code triggers an automatic alert.

the ethical dimension — naming vendors and protecting buyers

Publishing vendor names is a serious step, one that can affect livelihoods and invite legal challenges. Our policy is to name only when the evidence is conclusive — multiple independent confirmations, clear photographic proof, and, often, factory statements or authenticated auction records. In the case of a well-known vendor on a European platform offering a 2007 Měnghǎi (勐海) jīn yá (金芽) shou that was actually a 2012 production, we waited until three separate collectors provided microscopic wrapper analysis and a factory response confirmed the original batch date. The entry remains in the archive, and subsequent reports from other buyers confirmed the pattern. For those seeking safe sourcing channels, shop.thetea.app maintains a list of verified sellers whose stock is regularly cross-checked against known fakes. Additionally, tea.community hosts a dedicated discussion area where buyers can seek second opinions before committing, using the collective experience of hundreds of seasoned collectors. Transparency, patience, and shared evidence are the pillars of a trustworthy market.
