Conductivity Water Type I from Japan
Type I conductivity water is ultrapure water with resistivity exceeding 18 MΩ·cm, produced through distillation and deionization for use in semiconductor manufacturing and analytical laboratories. It qualifies under tariff item 2853.90.00 as 'water of similar purity' to distilled or conductivity water, a category explicitly included in this heading. Its high purity and lack of added substances ensure it is not classified elsewhere in Chapter 28.

Import Tips
• Ensure the water meets the purity threshold (resistivity >18 MΩ·cm) and carry a certificate of analysis to present to the CBSA if requested
• Declare the product under tariff item 2853.90.00 as 'water of similar purity' and be aware that no special permits are required for this inorganic compound
• Keep records of the production method (e.g
• distillation, deionization) to support classification
