Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as unfinished worked stone
Chapter 68 covers worked monumental/building stone; printing preparation moves it to Chapter 84.
If for non-stone lithographic components like plastic plates
Subheading distinguishes stones explicitly from other prepared printing components.
If raw limestone blocks before any preparation
Natural stone in blocks falls under Chapter 25 mineral products.

Import Tips & Compliance
• Provide geological certification confirming lithographic limestone quality to validate preparation
• Ensure stones measure under plate dimensions to avoid cylinder classification
• Document surface treatment (graining/polishing) process to distinguish from raw stone imports
