Amazon US FBA prep requirements (FNSKU labeling, poly bagging, carton labeling) are largely the same across Amazon's international marketplaces. The core prep workflow translates directly.
The key differences are in carton label formatting — international FCs use different shipment plan systems and label formats than US FCs. Create separate shipment plans in each marketplace's Seller Central before generating carton labels.
Language requirements differ by market. Germany requires German-language warnings on certain product categories. France requires French. Canada requires bilingual (English and French) labeling for products sold nationally.
For Amazon UK post-Brexit, inventory shipped to UK FCs is treated as an import — requiring UK customs documentation. Amazon handles the VAT side for FBA sellers, but the import declaration is the seller's responsibility.
