HSProof

HSProof helps cross-border sellers and 3PLs reduce customs delays by standardizing product classification and documentation before a shipment leaves the warehouse. You paste a product title, materials, images, and supplier specs; the app suggests likely HS codes per destination, flags missing attributes (composition %, intended use, wattage, etc.), and generates a “customs-ready” product sheet your team can reuse across orders. It also tracks which codes were accepted or challenged by customs brokers and carriers, building a feedback loop so your catalog gets more accurate over time. This is not a magic “guaranteed clearance” tool—classification is messy and varies by country—but it can materially reduce avoidable holds caused by vague descriptions and inconsistent coding. It’s a web app with optional API for Shopify/ERP/PIM sync, plus an AI-assisted classification assistant.
