HS Code 3403.91 – Lubricating preparations; for the treatment of textile and similar materials (leather, furskins etc), (not containing petroleum oils or oils obtained from bituminous minerals)
HS code 3403.91 is the 6-digit subheading for lubricating preparations, for the treatment of textile and similar materials (leather, furskins etc), (not containing petroleum oils or oils obtained from bituminous minerals). It is used for synthetic textile lubricants, bio-based leather fatliquors, water-soluble spinning oils, ester-based coning oils and silicone textile softeners.
What HS 3403.91 covers
This code covers lubricating preparations specifically for the treatment of textile materials, leather, furskins, and similar materials, which do *not* contain petroleum oils or oils obtained from bituminous minerals. These lubricants are typically based on synthetic esters, vegetable oils, or other non-petroleum chemistries, offering advantages such as biodegradability, improved color stability, or specific processing benefits where petroleum-based alternatives are unsuitable. They are crucial for specialized applications in textile finishing, leather processing, and fur treatment, particularly in industries seeking more sustainable or high-performance solutions. Trade involves specialty chemical manufacturers supplying textile mills, tanneries, and fur processors globally. Importers are often looking for eco-friendly or technically superior alternatives, while exporters focus on innovation in green chemistry. Understanding the specific material application and the absence of petroleum is vital for correct classification.

Codes often confused with 3403.91
Common mistake. These can be confused with petroleum-containing textile lubricants (340311) or other non-petroleum lubricants not for textiles (340399). The specific application and the complete absence of petroleum are the defining characteristics.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
