What Is Dual‑Code Traceability for Frozen Seafood?
Each bag of frozen shrimp or fish fillet has two codes:
Catch code (on the inner bag) – contains fishing vessel, catch date, catch area, species
Box code (on the outer box) – contains batch number, pack date, weight, destination
Dual‑code traceability means: You scan the bag code, then scan the box code. The system links them together. When a customer scans the outer box, they see both the packing info AND the catch origin.
If the two codes don‘t match (wrong bag in wrong box), the system rejects the package immediately.
Where Scanning Happens on a Seafood Processing Line
| Station | What You Scan | Why |
|---|---|---|
| Receiving frozen blocks | Catch code on each bag | Record vessel, catch date, species |
| Weighing / packing | Bag code before sealing | Link weight and pack date to catch code |
| Box packing | Box code after packing | Link outer box to inner bag codes |
| Case sealing verification | Box code + bag codes | Confirm correct bag in correct box |
| Palletizing | Pallet SSCC | Link all boxes to pallet |
XTIOT Scanners for Seafood Dual‑Code Traceability
🔹 XTS03 – Dual‑Code Verification System
Best for: Box packing station – ensures bag code and box code are correctly linked
Scan box code → scan each bag code inside → system verifies they belong together
Quantity check – alarm if wrong number of bags in box
Mismatch alert – wrong bag in wrong box? Workstation locks
Export reports – full traceability records for customs
🔹 XT8601B – Batch Scanner for Freezer Totes
Best for: High‑volume packing lines
Reads up to 100 codes in one scan – scan a whole tote of frozen bags at once
90 codes per second – keeps line moving in cold environments
Deep learning AI reads codes on wet, icy, or frosted surfaces
Detects duplicate or missing codes immediately
🔹 XT6202HD – Handheld Scanner for Receiving & Outbound
Best for: Warehouse receiving and shipping verification
Reads Data Matrix codes on frozen bags and boxes
2.4G wireless – connect to your warehouse PC
Point‑and‑shoot – simple for workers with freezer gloves
🔹 XT3001BHD – Hands‑Free Ring Scanner
Best for: Busy packing lines, hands‑free operation
Wear on finger – both hands free for handling frozen bags
Bluetooth + 2.4G wireless
Works with freezer gloves
Batch storage – keep scanning when wireless drops
Simple Dual‑Code Traceability Workflow
Frozen shrimp / fish fillet bags arrive in blocks
↓
Each bag has a catch code (vessel, date, species)
↓
Worker weighs bag → prints new bag code (weight, pack date)
↓
Worker scans bag code (new) → system records weight + pack date
↓
Bag goes into box
↓
At box packing station, XTS03 works:
1. Scan box code
2. Scan each bag code inside
3. System verifies: correct bag in correct box?
4. Wrong bag? Alarm + workstation lock
5. All correct? Case sealed
↓
Boxes stacked on pallet → pallet label printed
↓
Customer scans outer box → sees both packing info AND catch origin
What Codes Are Used
| Code | Where | Contains |
|---|---|---|
| Catch code | On inner bag | Vessel ID, catch date, catch area, species |
| Bag / weight code | On inner bag | Batch ID, weight, pack date, expiry |
| Box code | On outer box | Box ID, batch number, bag count, destination |
| Pallet SSCC | On pallet | Pallet ID, box count, total weight |
The XTS03 links bag code → box code → pallet code. Full traceability chain.
Why Seafood Processors Need Dual‑Code Scanning
| Problem | Without Traceability | With XTIOT Scanners |
|---|---|---|
| Wrong bag in wrong box | Customer complains, recall all | System rejects before sealing |
| Catch origin unknown | Can‘t prove sustainability | Scan code shows vessel, date, area |
| Customs rejects shipment | No traceability records | Full reports ready for export |
| Recall after contamination | Guess which batches | Exact batch, exact boxes |
