Chlorinated paraffins (CPs) are chemicals with multipurpose applications. Their global production has increased despite their adverse impacts on the environment and human health. In 2017, short-chain chlorinated paraffins (SCCPs) were listed as persistent organic pollutants (POPs) in the Stockholm Convention. Yet, specific exemptions were granted for their applications despite the recycling prohibition for products containing SCCPs. Therefore, we aimed to produce the first Brazilian inventory of SCCPs following its respective guidance to evaluate the applicability of the SCCP inventory guidance and to provide technical insights regarding SCCPs in the update of the Brazilian National Implementation Plan (NIP). Moreover, we performed a review of SCCP occurrence in Brazil to fulfil data gaps in the inventory development. We identified and consulted nationwide stakeholders and assessed foreign trade data of CPs and products that might contain CPs in relevant amounts. The Brazilian production of CPs was discontinued in 1994. However, CPs are still imported and used in the country. CPs have been mostly applied as plasticizers, flame retardants and lubricants in Brazil. The import of products containing CPs also pose a significant route of CP entrance into Brazil. Thus, the current end-of-life management of CP-containing products is a bottleneck towards the Convention implementation. The guidance application was feasible and useful despite the low engagement of stakeholders. To assess foreign trade of CPs and CP-containing products, we recommend the use of more specific tracking codes. Besides, the review of SCCP occurrence is not a demanded part for an inventory but was a useful complementation.

氯化石蜡 (CP) 是具有多用途应用的化学品。尽管它们对环境和人类健康产生了不利影响，但它们的全球产量仍在增加。2017年，短链氯化石蜡（SCCPs）被斯德哥尔摩公约列为持久性有机污染物（POPs）。然而，尽管禁止回收含有短链氯化石蜡的产品，但它们的应用获得了特定豁免。因此，我们的目标是按照各自的指南编制第一份巴西短链氯化石蜡清单，以评估短链氯化石蜡清单指南的适用性，并在巴西国家实施计划 (NIP) 的更新中提供有关短链氯化石蜡的技术见解。此外，我们对巴西的短链氯化石蜡发生情况进行了审查，以填补清单制定中的数据空白。我们确定并咨询了全国的利益相关者，并评估了 CP 和可能含有相关数量 CP 的产品的外贸数据。巴西的 CP 生产于 1994 年停止。但是，该国仍在进口和使用 CP。CP 在巴西主要用作增塑剂、阻燃剂和润滑剂。含有 CP 的产品的进口也是 CP 进入巴西的重要途径。因此，目前对含 CP 产品的报废管理是公约实施的瓶颈。尽管利益相关者的参与度很低，但该指南应用程序是可行且有用的。为了评估 CP 和含 CP 产品的外贸，我们建议使用更具体的跟踪代码。除了，
