It is increasingly realised that for a proper understanding of the illegal aspects of the international timber trade sound data on seizures is needed. Their value, however, may be greatly diminished in the absence of accurate reporting. International trade in rosewood is regulated through CITES, with large amounts trafficked illegally, and annually thousands of seizures are made. Unfamiliarity with the differences between ton and tonne as a unit of mass —the former equalling 907 kg and the latter 1000 kg and this is unrelated to US vs UK English spelling— has led to misreporting. Only the tonne is accepted by the Système international (and given the symbol t). Eighty-three independent reports of 19 large-scale rosewood seizures from nine countries (2013−2021) referred to mass in tonnes 48 times and in tons 35 times, without any conversion having taken place. The monetary value of rosewood in these seizures differed US$3246 t⁻¹ depending on whether ton or tonnes were used. Accurate reporting and conversion of mass to the same unit there where needed is especially relevant when presenting aggregate analyses of the illegal timber trade.

人们越来越意识到，为了正确理解国际木材贸易的非法方面，需要关于缉获量的健全数据。然而，如果没有准确的报告，它们的价值可能会大大降低。红木的国际贸易通过 CITES 进行监管，大量非法贩运，每年缉获数以千计。不熟悉作为质量单位的吨和吨之间的差异——前者等于 907 公斤，后者等于 1000 公斤，这与美国和英国的英语拼写无关——导致误报。Système International 仅接受吨（并带有符号 t）。来自 9 个国家（2013-2021 年）的 19 次大规模红木缉获的 83 份独立报告提到了质量以吨为单位的 48 次和以吨为单位的 35 次，没有发生任何转换。这些缉获中红木的货币价值相差 3246 吨^-1取决于使用的是吨还是吨。在对非法木材贸易进行汇总分析时，在需要时准确报告和将质量转换为同一单位尤其重要。
