Digital chain of custody & warranty
Batch tracking and official warranty certificates
Every product on LUWI Materials carries a laser batch code and a tamper-evident seal, so you know it came straight from the factory.
How LUWI's chain of custody protects your project
1
QC testing & laser batch code
The factory laser-prints a permanent batch code once the material passes strength and moisture testing.
2
Tamper-evident seal
The principal's warehouse seals each truckload with a unique tamper-evident seal number.
3
On-site OTP release
The driver enters a six-digit OTP from your site contact before the load can be unsealed.
4
Warranty activates automatically
The active factory warranty is recorded permanently in your project's digital ledger.
