AI-powered wet-blue grading at full line speed
Mindhive BlueSelect™ inspects and grades wet-blue and wet-white hides in 4 seconds. 30+ defect classes. Configurable grading rules. Verified data that follows every hide from grading line to customer.
Trusted by leading tanners worldwide
Why grading consistency matters
The grading decision at the wet-blue or wet-white stage is one of the most consequential moments in a hide's journey. It determines which order the hide goes to, which product it becomes, and what price it commands.
Manual grading has worked for generations. But it introduces variability. Grading differs by site, by shift, by person. What counts as an A-grade at one facility may not hold at another. Buyers still fly to facilities to check what they are actually receiving.
The downstream cost is real. To avoid disputes, tanneries over-deliver, sending better hides than the order requires. Premium material ends up in standard orders. Margin erodes quietly across thousands of hides, and it never shows up on a single line of any report.
Automated hide grading at wet-blue can cut downstream reject rates in half through optimal allocation, breaking down the information silos between grading, sorting, and fulfillment.
What is Mindhive BlueSelect™?
Mindhive BlueSelect™ is an AI-powered leather grading system for wet-blue and wet-white hides. It integrates behind existing sammying machines, operates at full line speed (up to 360 hides per hour), and grades each hide in 4 seconds. The system detects 30+ defect classes with defect resolution down to the size of a hair follicle.
Powered by a proprietary neural network trained on over 20 million hides (and counting), BlueSelect™ maps the percentage of detected defects across batches, measures total and cuttable area at pixel level, and applies your grading rules to every hide (tier dependent). The result is a verified grade that stays with the hide through every downstream decision.
The hide grade is displayed on an industrial touchscreen for manual sorting, or integrated directly into downstream automation systems such as auto stackers.

How BlueSelect™ streamlines your production
01.
High-resolution imaging
Every hide is scanned in high resolution, capturing the detail needed for accurate defect detection. Resolution reaches the size of a hair follicle.
02.
AI-powered inspection
Our neural network analyzes each image, identifying quality areas and defects with precision. It generates a unique defect map for every hide.
03.
Rule-based grading
Grading rules are applied consistently to classify each hide within 4 seconds. Ruleset configurability scales with your subscription tier.
04.
Detailed reporting
A verified grading report is produced for every hide: hide image, defect map, selected grade, batch number, and pallet data.
05.
Centralized dashboard
Production data and insights are accessible through Mindhive Cloud (tier dependent), enabling yield optimization, and sourcing analysis.
06.
ERP integration
Grading data can flow into your ERP system (tier dependent) to enhance workflow efficiency and data accessibility across your production chain.

Designed for demanding tannery environments
Mindhive BlueSelect™ is constructed from stainless steel and integrates with existing wringing processes, designed to fit conveyors and outfeeds. The imaging hardware is highly tolerant of variable conditions and processes images in real time on site.
Industrial-grade interactive touchscreens display a detailed defect map, usable and cuttable hide area, and the assigned grade. The system communicates directly to PLCs and auto stackers.
Deployments typically take only a few days, with minimal downtime. Mindhive has implemented systems in busy tanneries without disrupting production.
Same technology at the splitting stage
Mindhive SplitSelect™ uses the same AI grading technology as BlueSelect™, configured for the splitting stage. It adds another verified data point to the hide record, capturing quality changes that occur during splitting. This means the verified data that started at wet-blue grading continues to build as the hide moves through production.
Intelligent order fulfillment with Mindhive BlueSort™
Grading tells you what you have. Mindhive BlueSort™ tells you what to do with it. BlueSort™ is an intelligent order fulfillment solution that uses verified quality data from BlueSelect™ to optimize how inventory is allocated to customer orders.
Instead of re-sorting hides at every stage, BlueSort™ evaluates each hide against multiple orders simultaneously, matching the right hide to the right product. The result: fewer wrong-hide errors, reduced lead times, and shipments that can be trusted without re-inspection.
SKU Builder
Define customer-specific order profiles and calibration criteria. Each SKU captures the quality parameters that determine which hides qualify for that order, connecting verified data to fulfillment decisions.
Order Scheduler
Evaluate pallet-level inventory against active customer orders. The scheduler identifies which pallets can be shipped directly, which need re-selection, and where the best allocation opportunities are.
Sorting Station
The mobile sorting station displays each hide's defect map, pallet routing destination, and real-time throughput metrics directly on screen. Sorters see exactly where each hide should go.
BlueSelect™ + BlueSort™:
the full wet-blue workflow
BlueSelect™ creates the verified data. BlueSort™ acts on it. Together, they connect the grading line to order fulfillment in a single data-driven workflow.
1
BlueSelect™ scans and grades every hide at the wet-blue stage, creating a verified quality profile.
2
Verified data flows into Mindhive Cloud, where it becomes searchable across your entire inventory.
3
BlueSort™ evaluates inventory against active customer orders, matching hides to their highest-value use.
4
The Sorting Station App routes each hide to the correct pallet, with defect maps and destination on screen.
5
Pre-sorted shipments leave with verified grade reports attached. Buyers receive exactly what was specified.
JBS Couros deployed BlueSelect™ across 10 Brazilian wet-blue sites. Each site was calibrated for regional defect variation, with the defect catalog expanding to 30+ for Brazilian hides. Graders were not replaced; their role shifted from being checked to operating the system and monitoring data quality.
At Tasman, the system halved reject percentages downstream and optimized hide allocation. At every site, the same principle holds: once you have verified data, you can use it to refine grading rules, benchmark across sites, and make allocation decisions you could not make before.
91% grading accuracy at wet-blue, validated in a controlled study. Fast grading rule configuration and deployment (tier dependent). A configurable defect catalog where the defects actionable in grading rules scale with your tier.
