SDS (MSDS) Report Services for Desiccant Customs Clearance
Overview
An SDS (Safety Data Sheet) is a document—distinct from a standard test report—prepared in accordance with GHS (Globally Harmonized System) standards. It is required for the export, customs clearance, and booking of sea or air freight for desiccants. Common types include silica gel, calcium chloride, montmorillonite, and calcium oxide. Calcium chloride and calcium oxide pose risks of irritation and are subject to heightened scrutiny by freight forwarders and customs authorities. While standard, colorless silica gel is generally classified as non-hazardous, an SDS is still frequently requested for cross-border shipments. Color-changing (indicating) silica gel, which contains cobalt chloride, carries a higher risk and requires specific hazard labeling.
Core Components of an SDS
An SDS consists of 16 mandatory sections:
Product Identification; Composition/Information on Ingredients (including CAS numbers); Hazard Identification; First-Aid Measures; Fire-Fighting Measures; Accidental Release Measures; Handling and Storage; Exposure Controls/Personal Protection; Physical and Chemical Properties; Stability and Reactivity; Toxicological Information; Ecological Information; Disposal Considerations; Transport Information; Regulatory Information; and Other Information. For exports to the EU or the US, a bilingual (Chinese-English) version is typically provided.
Required Information
1. Product name and type (e.g., silica gel, calcium chloride, montmorillonite, or calcium oxide).
2. Complete formulation, including CAS numbers for each component and their respective proportions.
3. Packaging type (e.g., small sachets, container-hanging strips) and intended use.
4. Export destination and mode of transport (sea or air freight).
5. Manufacturer details and an emergency contact phone number.
Processing Steps
1. Verify the desiccant’s material composition to determine if it contains hazardous substances.
2. Submit the required information and complete the service request form.
3. An engineer prepares the SDS in accordance with GHS standards (bilingual: Chinese and English).
4. Review and finalize the document, then issue the SDS in PDF format.
5. For air or sea shipments, a "non-hazardous" classification report (non-dangerous goods certificate) can also be provided to prevent cargo detention.
Turnaround Time and Important Notes
Standard turnaround time is 1–3 business days.
If there are any changes to the formulation or raw materials, the SDS must be updated. For calcium chloride or quicklime desiccants—even if the SDS classifies them as irritants—air freight carriers generally require a formal transport identification report. Similarly, for small packets of silica gel desiccant included with shipments, many overseas clients and customs authorities may request an SDS for reference. Please note that an SDS is valid only for the specific sample for which the formulation was submitted.
