Corrugated & Solid Fiber Boxes (NAICS 322211) imports of $96.4M in August 2026 ran 18% above the year-to-date monthly average of $81.8M.
Last updated: August 2026 dataCorrugated and solid fiber boxes are the workhorses of industrial and e-commerce shipping, engineered to specific flute profiles (A, B, C, E, or F flute) and wall constructions (single-wall, double-wall, triple-wall) that determine compression strength and puncture resistance. Box performance is certified under either the Mullen burst test or the edge crush test (ECT) standard, and the applicable standard must match the carrier's tariff requirements for freight liability. Section 301 tariffs have applied to certain corrugated box imports from China, making origin diversification a live consideration for high-volume importers.

Flute type (A through F) determines cushioning, stacking strength, and printability: A-flute offers maximum cushioning, while E and F flutes provide a smoother surface for high-quality printing. Double- and triple-wall constructions multiply compression strength for heavy industrial loads. These structural choices affect both the box's performance certification and, in some cases, its HTS classification, so specifications should be confirmed before import.
Yes — certain corrugated and fiber box imports from China have been subject to Section 301 tariffs. The applicable tariff list and product scope should be verified against current USTR guidance, as product exclusions and list modifications have occurred over time. Importers should work with a licensed customs broker to confirm current duty exposure for their specific HTS classification.
