Plain-language overview
Use HS-4 2522 when importing quicklime, slaked lime, or hydraulic lime. For example, if you're shipping a bulk load of quicklime for construction purposes, this heading applies. It’s essential to classify your product correctly to avoid delays and penalties.
When deciding between HS-6 252210 for quicklime and HS-6 252220 for slaked lime, consider the product’s form. Quicklime is typically a dry powder, while slaked lime is a hydrated form that may appear as a paste or powder. This distinction is crucial for accurate tariff classification.
If your shipment includes hydraulic lime, which is used for construction and has specific binding properties when mixed with water, you should use HS-6 252230. This lime is distinct from quicklime and slaked lime due to its unique composition and applications in building materials.
