U.S. exports of residues of petroleum or bituminous oils (nesoi) (HS 271390) totaled $818K in July 2026.
Last updated: July 2026 dataAcid oils, tank bottoms, and other petroleum residues not elsewhere specified fall into this catch-all heading, which captures the heterogeneous byproducts of petroleum refining and bituminous oil processing that do not meet the specific definitions of petroleum coke, bitumen, or other named residues. These materials are used in secondary refining, as fuel blendstocks, or as feedstocks for carbon black production. Canada and Mexico are the leading US import sources, reflecting the deep integration of North American refinery operations and the cross-border movement of refinery intermediates. All trade enters under the single line 2713900000.

Products frequently classified here include clarified slurry oil, decant oil, acid sludge from sulfuric acid refining, and heavy fuel oil residues that do not meet the specific definitions for petroleum coke (2713110000/2713120000) or petroleum bitumen (2713200000). The NESOI designation means classification should be confirmed by exclusion — if the product fits a more specific heading, it belongs there rather than in 271390.
Integrated US-Canada and US-Mexico refinery networks frequently move intermediate streams and residues across borders for further processing. These flows can complicate country-of-origin determinations, particularly when a residue is processed in one country from crude originating in another. Importers should document the refining process and apply the applicable substantial transformation or tariff-shift rules to establish origin correctly.
