Understanding Fertilizer GHS Classifications, UN Transport Numbers & MSDS Safety Sheets

For global shipping lines, container freight forwarders, port customs inspectors, and chemical warehouse logistics managers, understanding international regulatory compliance is essential to ensure lawful, safe, and expedited transit of bulk mineral salts. The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) and the International Maritime Dangerous Goods (IMDG) Code govern packaging, transport documentation, and hazard labeling across all international ocean trade lanes.

1. Structure of the 16-Section GHS Safety Data Sheet (SDS)

Auron provides comprehensive 16-section SDS documents for every product batch, structured according to ISO 11014 and GHS Rev. 9 standards:

• •Section 1–3 (Identification & Composition): Official IUPAC name, commercial product grade, CAS numbers, EC numbers, and active purity assay percentages.

• •Section 4–8 (Safety & Handling): First-aid protocols, firefighting measures, accidental spill containment, and personal protective equipment (PPE) requirements.

• •Section 9–11 (Physical & Toxicological Properties): Specific gravity, melting point, water solubility curves, acute oral LD50 values, and skin/eye irritation indices.

• •Section 14 (Transport Information): UN numbers, proper shipping names, hazard classes, packing groups, and marine pollutant declarations.

2. UN Transport Numbers & IMDG Classification Breakdown

• •Zinc Sulphate Monohydrate (ZnSO4 · H2O):

- UN Number: UN 3077 - Proper Shipping Name: Environmentally Hazardous Substance, Solid, N.O.S. (Zinc Sulphate Monohydrate) - Class: Class 9 (Miscellaneous Dangerous Substances and Articles) - Packing Group: PG III (Low Danger) - Marine Pollutant: Classified as an aquatic environmental hazard; requires GHS Fish/Tree environmental pictogram on all export bags.

• •Copper Sulphate Pentahydrate (CuSO4 · 5H2O):

- UN Number: UN 3077 - Proper Shipping Name: Environmentally Hazardous Substance, Solid, N.O.S. (Copper Sulphate Pentahydrate) - Class: Class 9 / Marine Pollutant - Packing Group: PG III - Handling: Requires heavy-duty woven polypropylene bags with hermetically sealed inner liners to prevent ocean cargo contamination.

• •Ferrous Sulphate Heptahydrate (FeSO4 · 7H2O):

- Transport Status: Non-Hazardous for Road and Maritime Transport (Not regulated under IMDG/IATA as dangerous goods for dry containerized freight).

3. Export Labeling & Container Placarding Standards

Every export container dispatched from Auron's facility to Mundra or Kandla Port complies with strict maritime placarding rules:

• •Container Exterior: High-visibility Class 9 diamond hazard placards affixed to all four exterior walls of the 20ft FCL container.

• •Bag Stenciling: Every 25kg or 50kg bag displays the UN number, batch code, net weight, gross weight, GHS signal word ("WARNING"), and manufacturer contact coordinates.

4. Customs Clearance Best Practices for Importers

To avoid port demurrage and customs inspection holds, overseas buyers must receive verified original digital copies of the SDS, COA, and Commercial Invoice 7 to 10 days prior to vessel berthing at the destination port.
