Bleached Plastic-Coated Paper and Paperboard, Over 150 g/m²

Bleached paperboard coated, impregnated, or covered with plastics and weighing more than 150 g/m² is a critical substrate for liquid-packaging cartons, food-service trays, and folding-carton applications requiring moisture or grease resistance. The US schedule dedicates specific lines to milk-carton and beverage-container base stock (4811512010), folding-carton stock over 0.3 mm thick (4811512020), tray base stock (4811512030), and general packaging base stock (4811512040), reflecting the heading's importance to food and beverage packaging supply chains. Mexico leads US imports, followed by Germany and Canada. Because many end-uses involve direct food contact, importers should confirm that the plastic coating complies with FDA food-contact regulations under 21 CFR.
