What problem does it solve? Cross-border sellers face fragmented rules across product eligibility, tax registration, HS classification, and fulfillment routes, and wrong answers can block shipments or trigger penalties. This Skill structures those decisions around official sources, SKU-level evidence, and reconciled calculations instead of guesses. ## Core Features & Use Cases - Compliance and admission screening: Check prohibited/restricted products, certification, labeling, claims, dangerous goods, and platform policy risk per SKU and batch. - Tax, IP, and customs workflows: Analyze VAT/GST/Sales Tax, OSS/IOSS, Nexus, trademark/authorization risk, HS codes, tariffs, DDP/DDU, and China import requirements with official source routing. - Evidence-bound file reconciliation: Reconcile invoices, packing lists, SKU masters, and quotes into control totals and calculation ledgers before producing Excel/CSV/Word deliverables. - Use Case: A seller asks whether a battery-powered product can be shipped DDP to an EU warehouse. The Skill extracts trade fields, checks battery and customs evidence, flags P0/P1 blockers, and lists the exact closing documents and verification paths. ## Quick Start Ask whether a specific product can be sold and shipped to a target country on a given platform, and attach any invoices, packing lists, or SKU files for review.
