HS Code for Leaded gasoline sludge

Leaded gasoline sludge is classified under HS code 2620.21. This classification is highly specific and is dictated by the chemical nature and origin of the residue. These sludges are obtained from the storage tanks of leaded gasoline and leaded anti-knock compounds (such as tetraethyl lead). They consist essentially of lead, water, and organic matter (including unrecovered gasoline or anti-knock compounds). The Harmonized System separates these from general metallurgical lead residues because of their specific origin in the petroleum distribution chain and their distinct chemical hazards. Under Chapter 26, heading 2620, the international community created subheading 2620.21 to ensure these specific hazardous residues are tracked separately from standard industrial slag or ash.

Products Included

• Leaded gasoline storage tank sediments
• Leaded anti-knock compound sludges
• Tetraethyl lead residues from cleaning operations
• Sludge from leaded fuel filtration systems

Common Misclassification

The most frequent misclassification occurs with HS code 2620.29, which covers "other" lead residues. While 2620.29 is for general metallurgical slag and ash, 2620.21 is mandatory for residues specifically containing anti-knock compounds or originating from leaded gasoline tanks. Another misclassification is HS code 3811.11, which covers the actual anti-knock preparations themselves; however, once the product becomes a waste sludge or residue, it must be moved to Chapter 26.

FAQ

What is the HS code for leaded gasoline sludge?

The HS code for leaded gasoline sludges and leaded anti-knock compound sludges is 2620.21.

Why is this sludge not classified as a chemical product in Chapter 38?

Chapter 38 covers functional chemical products and preparations. Once the material is a residue or waste intended for metal recovery or disposal, it is classified under heading 2620 as a residue containing metal.
