Mercury Calibration Standard
NIST-traceable mercury standard solution or metal (10,000 ppm Hg) for analytical instrument calibration, with matrix-matched accuracy for AAS and ICP-MS analysis. This product is classified under tariff item 2805.40.00 for the elemental mercury component, as it is a separate chemical element. The solution form may be considered a dissolved product under Chapter 28 Note 1(b), but the mercury itself is the primary component.

Import Tips & Compliance
• Verify whether the calibration standard is a solution or pure metal; if it is a solution, ensure it meets the criteria of Chapter 28 Note 1(b) for classification under 2805.40.00
• Provide a certificate of analysis and NIST traceability documentation to the CBSA
• Check if any special permits are required for importing mercury-containing calibration standards
