Here is some information on restrictions and regulations regarding the transportation of microsilica (silica fume) by land, air and sea in different countries:
Silica Fume Transportation Restrictions
United States:
- Land – No significant restrictions. Follow general hazardous materials transportation regulations.
- Air – Considered non-hazardous for air transportation. IATA regulations apply.
- Sea – Considered non-hazardous unless transported by bulk. IMDG code regulations apply. Follow packaging and labeling requirements.
China:
- Land – No special permits required for domestic transportation. Follow national regulations for hazardous goods transportation.
- Air – Considered non-hazardous. Follow IATA dangerous goods regulations.
- Sea – Considered non-hazardous solid unless shipped in bulk. Comply with IMDG code and Maritime Safety Administration of China requirements.
European Union:
- Land – Considered non-hazardous. Obey ADR regulations for packaging, marking and documentation.
- Air – Per IATA regulations, not subject to dangerous goods restrictions.
- Sea – Non-hazardous solid unless shipped in bulk. Follow IMDG code standards.
India:
- Land – Domestic transportation allowed without special permits. Follow motor vehicle act and central motor vehicles rules.
- Air – Treated as non-dangerous under IATA rules.
- Sea – Non-hazardous solid unless shipped in bulk quantities. Abide by Merchant Shipping Act and IMDG code.
In general, microsilica is usually not classified as hazardous for transport if properly packaged and labeled. But local requirements may vary, so import/export regulations in each specific country need to be checked for land, sea and air shipment compliance.
