Last updated: April 2026 dataSewage sludge — the semi-solid residual material produced during wastewater treatment — enters US commerce under tariff line 3825200000 and is subject to EPA regulation under the Clean Water Act's biosolids framework (40 CFR Part 503). Cross-border trade in this material is uncommon but does occur in the context of beneficial reuse programs, such as land application or composting, where treated sludge is marketed as a soil amendment. Importers must confirm that the material meets EPA pathogen-reduction and heavy-metal concentration standards before any land-application end use is permitted.

Potentially, but only if the material meets EPA's Part 503 biosolids standards for pathogen reduction and pollutant concentration limits. Importers should obtain documentation from the foreign treatment facility confirming compliance with equivalent standards before pursuing a land-application end use.
Sewage sludge (382520) is specifically the semi-solid residual from wastewater treatment processes, while municipal waste (382510) covers mixed solid refuse from households and commercial premises. The two streams have distinct regulatory profiles and should not be commingled for classification purposes.
