Under USMCA Chapter 4, any shipment classified under HS Code 3825.0 without proof of 'Wholly Obtained Good' status faces a 40% transshipment penalty. On a 19.15-tonne Mothership load valued at $2,850, that's $1,140 in tariff exposure. The 905WOOD USMCA Shield is a 9-Point Certificate of Origin — a cryptographically verified, high-contrast PDF optimized for CBP officer scrutiny at the Ontario-Michigan border. Every data point is hardware-attested by the Titan M2 security chip on the Pixel 10 Pro. The 9 Points: GPS Origin Coordinates, HS Classification (3825.0), XRF Atomic Signature, USMCA 'Wholly Obtained Good' Attestation, Site Origin Declaration, AI Model Version & Metadata, Net Weight, O.Reg 347 Compliance Check, and Cryptographic Blockchain Hash. Without CoO: $1,140 penalty. With CoO ($125): $0 penalty. ROI: 812%. At fleet scale (200 loads/week), the USMCA Shield generates $288,400 per week in tariff avoidance.
