Goods Across Borders is an independent customs and international shipping reference designed to help people understand rules before they travel, send parcels, or import goods commercially. It presents more than 5,300 source-backed rules covering 85 countries, alongside information on 111 catalogued items. Its stated approach is sourced, dated, and neutral, with pages explaining its coverage, methodology, source health, editorial policies, and updates.

The site serves travellers, parcel senders, and importers with practical lookup tools and reference material. Travellers can check country rules, allowances, airport guidance, airline cabin policies, and prepare with packing lists or declaration support. Parcel senders can review shipping requirements, compare carriers, and use a customs-form helper. Importers can explore duty calculations, landed costs, commercial invoices, Incoterms, document checklists, and HS codes.

Additional resources cover countries, items, trade routes, free trade agreements, dangerous goods, and sanctions regimes, as well as focused topics such as pets, drones, vehicles, and household effects. Developers can also consult the site’s API documentation and OpenAPI specification.
