What Fretix does
Fretix reads your DG cargo documents, verifies the classification data against source documents, and generates filled IMDG Dangerous Goods Declaration (DGDI) files — one per declaration group — ready to submit to your shipping line.
Fretix does not replace the required document formats. It replaces the manual work of transferring data from your source documents into those formats.
Step 1 — What you need to upload
Required: Annexure Excel file
Your annexure must be an Excel file (.xlsx or .xls) with the following minimum columns. Column names do not need to match exactly — Fretix uses fuzzy matching.
| Column |
Required |
Purpose |
| Material Description |
Required
|
Product name / description |
| UN Number |
Required
|
Used to group products onto the correct DGDI |
| UN Proper Shipping Name |

|
Official IMDG shipping name |
| HAZ CLASS |
Required
|
IMDG hazard class (e.g. 3, 6.1, 8) |
| PKG Group |
Required
|
Packing group (I, II, or III) |
| MARINE POLLUTANT |
Required
|
YES or NO |
| FLASH POINT |
Required
|
e.g. 24 DEG CEL |
| UN Certificate No. 1 |
Required
|
Full UN marking string, e.g. 4G/Y 8/S/25 IND/08108730 |
| No. of Boxes / Drums |

|
Outer packages count |
| No. in TINS |
Required
|
Inner packages count |
| Gross Wt. in KG |
Required
|
Gross weight per product line |
| Net WT. in KG |
Required
|
Net weight per product line |
| EMS |
Recommended
|
Emergency schedule, e.g. F-E, S-E |
| Technical name |
Recommended
|
Chemical / technical name |
| Product Code |
Optional
|
Links rows to MSDS files for verification |
| UN Certificate No. |
Optional
|
Short cert ref for cross-verification |
Optional: MSDS PDFs
Upload all Safety Data Sheets for the products in your shipment. Fretix will extract the 6 DG classification fields from each MSDS and cross-verify them against your annexure.
Each MSDS must contain the product code somewhere in the document (Section 1, Product identifier). Fretix uses this to match the MSDS to the correct annexure row. Filenames do not matter.
Optional: UN Certificate PDFs
Upload all UN packaging certificates. Fretix will extract the full UN marking string and validity date, then cross-check that the short cert reference in your annexure matches the certificate number in the document.
Scanned certificates (image PDFs) are supported but extraction accuracy depends on scan quality. Digital PDFs (text-selectable) give the most reliable results.
Step 2 — Verification results
After uploading, Fretix shows a row-by-row verification table. Each row is flagged as:
OK
All fields present. If MSDS and UN cert were uploaded, they matched the annexure values.
Warning
A matching document was not found for this row (MSDS or UN cert not uploaded). The annexure data will be used as-is.
Error
A mismatch was found between the annexure and the source document. Review the flag details before proceeding.
You can proceed to generation even if flags are raised. Fretix generates declarations from the annexure data. Flags are warnings for your review, not blockers.
Step 3 — Carrier and shipment details
Select your shipping line and fill in shipment-level fields. These are left blank in the generated declarations:
· Ship name and voyage number
· Booking number
· Signatory fields
These must be filled manually in the downloaded files, as they are shipment-specific and not available in the annexure.
Enterprise clients
If your organisation sends regular shipments in a fixed format that differs from the standard annexure structure, contact us to discuss a custom integration. Enterprise clients with consistent data formats can bypass the 5–7% per-shipment iteration that comes with format variation.
