HS HEADING 2522

Quicklime, slaked lime and hydraulic lime; other than calcium oxide and hydroxide of heading no. 2825

In plain English

This category includes quicklime, slaked lime, and hydraulic lime, but specifically excludes calcium oxide and hydroxide found in heading 2825. The goods are divided into three distinct types based on their specific form: quicklime, slaked lime, and hydraulic lime. Each of these three forms is treated as a separate classification within this group.

Chapter 25 classification notes

Chapter 25 covers bulk industrial materials; most are duty-free under MFN. Specialty salts (Himalayan, Maldon) face the same tariff classification as industrial table salt.

Frequent misclassification in this chapter

Worked marble / granite goes to Chapter 68 (articles of stone) not 25; raw blocks stay in 25.

Classification certainty

The 6-digit level shown here is the internationally harmonised layer. Duty rates attach to national 8-10 digit tariff lines, which differ by country — use the duty calculator for lane estimates. For binding certainty, request a ruling from the destination customs authority.
