HS Code for Slack wax

Slack wax is classified under HS code 2712.90. This product is a crude mineral wax obtained during the dewaxing of lubricating oil base stocks. It is characterized by a relatively high oil content, typically ranging from 5% to 30%, though the HS definition requires it to contain at least 0.75% oil by weight to be distinguished from fully refined paraffin wax. Chapter 27 covers mineral fuels and oils, and heading 2712 specifically addresses petroleum jelly and mineral waxes. Since slack wax is an intermediate product and not a fully refined paraffin wax (which falls under 2712.20), it is categorized under the "other" subheading 2712.90. Its classification depends on its mineral origin and its physical state as a solid or semi-solid wax at room temperature. It serves as the primary feedstock for the production of refined paraffin wax and is also used in the manufacturing of particle board, matches, and rust preventatives. The classification is determined by the refining stage and the specific oil-to-wax ratio present in the substance.

Products Included

• Light slack wax
• Heavy slack wax
• Crude paraffin wax with oil content above 0.75%
• Unrefined petroleum wax
• Slack wax used for candle feedstock

Common Misclassification

The most frequent misclassification for slack wax is HS code 2712.20, which is reserved for paraffin wax containing less than 0.75% oil by weight. If the refining process has removed the majority of the oil, the product moves from 2712.90 to 2712.20. Another error involves HS code 3404.90, which covers artificial waxes and prepared waxes. Slack wax is a natural mineral product obtained through physical separation (refining) and does not contain the chemical modifications required to be classified as an artificial wax. Additionally, vegetable-based waxes should be classified in Chapter 15, not Chapter 27.
