HS Code 3825.90 – Residual products of the chemical or allied industries, not elsewhere specified or included; n.e.c. in 3825 or 27.10
HS code 3825.90 is the 6-digit subheading for residual products of the chemical or allied industries, not elsewhere specified or included, n.e.c. in 3825 or 27.10. It is used for mixed chemical waste streams, unspecified laboratory waste, industrial effluent residues, spent processing aids and contaminated packaging (chemical).
What HS 3825.90 covers
This HS code serves as a 'basket' category for residual products of the chemical or allied industries that are not specifically classified elsewhere within Chapter 3825 or Chapter 27.10. It captures a diverse range of waste streams that don't fit neatly into organic or inorganic classifications, highlighting the complexity and variety of industrial by-products. Trade in these materials is typically handled by specialized waste management companies and environmental service providers. The nature of these 'other' wastes means that each shipment can be unique, requiring careful assessment for hazardous properties, potential for recycling, or appropriate disposal methods. This category underscores the global challenge of waste management and the need for robust classification systems to ensure safe and compliant international movement.

Codes often confused with 3825.90
Common mistake. This code is a residual category, so misclassification often occurs when a waste *could* be more specifically classified under 382561 (organic) or 382569 (inorganic) but is broadly categorized here due to mixed composition or lack of detailed analysis.

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).
