Tariff Designation
International trade Harmonized System codes assign specific six-digit numerical descriptors to manufactured goods for duty assessment and statistical tracking. Under this framework, customs classification HS 4819 covers cartons, boxes, cases, bags and other packing containers made of paper, paperboard, cellulose wadding or webs of cellulose fibers. Tariff schedules use this heading to categorize both rigid shipping containers and folding packaging products.
Material Boundary
Subheading selection within heading 4819 depends on structural construction and material composition. Folding cartons made of non-corrugated paperboard fall under subheading 4819.10 or 4819.20 depending on regional tariff breakdowns, whereas corrugated boxes belong strictly to subheading 4819.10. Assigning customs classification HS 4819 requires verifying that paper products are formed into functional packaging containers rather than flat sheets or rolls, which reside in headings 4802 through 4811.
Articles containing composite materials retain this classification provided paperboard supplies the essential character of the completed container. Misclassification between corrugated shipping cases and solid folding boxes results in incorrect duty calculations and administrative penalties during cross-border shipments.
Regulatory Compliance
Cross-border trade documentation relies on accurate product descriptions paired with matching tariff codes to satisfy border control requirements. Improper application of customs classification HS 4819 exposes importers to audit scrutiny and delayed clearance at ports of entry.
