AI Durian Grading A·B·C
Why is standard A-B-C grading needed?
Export markets are tightening quality requirements — each market has its own standards for weight, shape, and internal condition of durians.
Manual grading depends on personal experience, is prone to errors, and lacks data verification. This leads to rejected shipments, commercial losses, and damaged trust with partners.
Pione Trace's AI system applies consistent standards without subjective bias, while saving all classification data to the Blockchain for retrieval when needed.
Grade A · B · C Criteria
Each durian is simultaneously evaluated by AI on 12 appearance and quality criteria, accurately sorting it into the correct commercial grade.
Grade A
Export Grade
- Weight from 1.9-5.2kg
- Beautiful shape, even pods
- Pest-free, crack-free skin
- Ripening time 7-10 days
Meets export standards
Grade B
Premium Domestic Grade
- Weight 1.8 – 5.5 kg
- Relatively beautiful shape, uneven pods
- No pests, minor cracks allowed
- Ripening time 4-7 days
Supermarkets, high-end domestic store chains, good sales price.
Grade C
Processing Grade
- Weight 1.4 – 4 kg
- Temporary shape, uneven pods
- No pests, acceptable cracks
- Ripening time 3-5 days
Suitable for processing: ice cream, cakes, candies, frozen durian pulps.

Frequently asked questions
Does the A-B-C-D classification system completely replace manual labor?
The system replaces 100% of the manual sorting steps on the line. Staff shift to monitoring and handling exceptions, reducing sorting labor costs by 70–80%.
What is the maximum sorting capacity of a single line?
A standard module processes 1.5–3 tons/hour depending on conveyor size. The system can scale parallel modules for large-scale facilities.
Can classification data be exported as reports by order?
Yes. The dashboard allows filtering and exporting reports by shift, day, batch, or specific order — supporting reconciliation with buyers and quarantine authorities.
Can grading standards be customized for each market?
Absolutely. The system allows configuring grading thresholds according to each export market (China, Japan, South Korea) or the specific requirements of the buyer.
