US Duties on PP Boxes from China & Vietnam: The Philippines Alternative

If you import polypropylene (PP) corrugated boxes — corrugated plastic reusable produce and logistics boxes — into the United States, 2026 changed your cost structure dramatically. Here are the official numbers, published by the U.S. Department of Commerce's International Trade Administration.

The determinations, in numbers

Origin	Measure	Final rate	Determination
China	Anti-dumping (A-570-207)	83.64% (82.21% cash deposit)	Jan 16, 2026
China	Countervailing duty (C-570-208)	62.27% (all companies)	Jan 16, 2026
Vietnam	Anti-dumping (A-552-850)	130.58% (Vietnam-wide)	May 18, 2026
Philippines	—	Not subject to these orders	—

In practice: a Chinese-origin PP box that cost $4.00 now carries roughly $5.78 of indicative AD/CVD cash-deposit exposure on top, plus 37.5% in Section 301 tariffs — about $11.28 duty-inclusive before freight; a Vietnamese-origin box adds about $5.20 plus 12.5% Section 301 (≈ $9.72); a Philippine-origin box pays 0% under these orders plus the 12.5% Section 301 tariff (≈ $4.50). Figures exclude the 3% HTSUS MFN duty and use published country-wide rates. The AD/CVD alone can exceed the price of the box itself.

Why this happened

US producers petitioned that PP corrugated boxes from China and Vietnam were being sold below fair value. Commerce's final determinations applied rates based on facts available with adverse inferences — which is why the China-wide and Vietnam-wide rates are so high, and why they apply broadly rather than to a few named exporters. The International Trade Commission's injury findings completed the process in 2026.

The Philippines route

The orders name China and Vietnam only. PP corrugated boxes genuinely manufactured in the Philippines are outside their scope. That means 0% under those specific AD/CVD orders, not zero total U.S. tariff. Published measures include the 12.5% Section 301 tariff on products of the Philippines (in effect since July 24, 2026; the earlier 19% IEEPA reciprocal tariff ended February 20, 2026) plus the normal HTSUS duty; classification, exclusions, entry date and stacking must be confirmed by the importer and customs broker. Two additional origin-compliance points matter:

• Origin must be real. Merely transshipping Chinese boxes through Manila is circumvention — CBP actively investigates it, and penalties land on the importer. What you need is genuine Philippine production with substantial transformation on site.
• Documentation matters. Work with a manufacturer that can provide complete production records, raw material traceability and certificates of origin from the Philippine authorities.

This is exactly what Fuxing Group offers: our Calamba, Laguna (15,000 m²) and Davao (80,000 m²) plants run genuine extrusion-to-finishing PP box production in the Philippines, under the same group quality system as our Chinese and Vietnamese plants — ISO 9001 / ISO 14001 certified, full origin documentation with every shipment.

What US buyers should do now

• Audit your current PP box supply chain's country of origin — the duty applies at entry, to the importer of record
• Re-quote your program from a Philippine origin and compare true landed cost
• Qualify the new origin before your next season's volume commitment — sampling and spec transfer take 2–4 weeks
