I've not worked with smart contracts personally, so take it with a grain of salt, but... This problem seems to be mostly solved by the information available in shipping manifests; the locations of loading and unloading, the consignee (buyer), container ids, description of goods... all there in a publicly available (at cost) record. The real difficulty has more to do with verifying the quality - I'll admit I'm at a loss to how that's done today and I can't imagine quality assessors are at the port to verify that container #123 contains the shipment of Grade B+ cotton or map that to an API. As well, what happens when you disagree and your own independent assessor says its Grade B-? This seems like something that would remain up to legal debate; probably denoted in the contract but not verified by it such that lawyers and assessors can handle it should problems arise. Just my two cents.
