The political case against secondhand clothing exports to sub-Saharan Africa has never required evidence. It has required only a plausible story: that wealthy nations, drowning in fast-fashion surplus, use poorer ones as disposal sites for textile waste they cannot manage at home. That story has circulated through regulatory consultations, parliamentary debates, and international treaty discussions with the confidence of established fact.
A field study published recently by the Sustainable Manufacturing and Environmental Pollution (SMEP) Programme, implemented in partnership with UN Trade and Development (UNCTAD), now places it against primary data, and the distance between the narrative and the numbers is large enough to reframe the regulatory conversation.
The study examined 244,500 garments sampled from imported bales across major markets in Uganda and Tanzania. Approximately 96% of those items were rewearable and suitable for resale. Only 1.1% to 1.3% qualified as textile waste under the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) definition: material designated for final disposal with no recycling or reuse pathway. A further 2.9% to 3.2% were classified as rags, items downgraded from rewearable status but retaining industrial resale value. The combined fraction falling outside Harmonized System (HS) Code 6309, the international classification for secondhand clothing intended for reuse, ranged from 3.3% to 4.8% across both markets and grade types.
These are not figures at the margins of the debate. They are central to it. The European Union (EU) is developing extended producer responsibility (EPR) frameworks for textiles. The US Environmental Protection Agency is building a national textile recycling strategy. The Basel Convention is in active discussion about whether used clothing should be reclassified as controlled waste. Each of those processes has been shaped, to varying degrees, by the assumption that imported secondhand clothing arrives in developing markets as thinly disguised refuse. The field data do not support that assumption. They contradict it.
The findings come from Trade in Secondhand Clothing: Analysis of Markets in Uganda, the United Republic of Tanzania and the United States of America, authored by Jennifer Wang and Richard Wang and published by the SMEP Programme in partnership with UNCTAD in April 2026. The study combined field surveys across major markets in Kampala and Dar es Salaam with upstream analysis of the US secondhand clothing supply chain, engaging 2,147 respondents across importers, retailers, vendors, and tailors, and drawing on trade data from UN Comtrade and national revenue authorities.
What the data force into view is a more precise question. The issue is not whether some waste enters importing markets; the figures confirm that it does, at a fraction below 1.5% in most bales. The issue is why that fraction is so low, and whether the regulatory responses being designed upstream have been calibrated to the actual system or to its caricature. The answer to the first question turns out to be structural: the economics of the secondhand clothing trade actively penalise waste at every point in the supply chain. The answer to the second is less reassuring.
