On September 9, 2026, the American Pizza Box Manufacturers Coalition — comprising packaging giants Smurfit Westrock and Pratt Industries — joined by the United Steelworkers union, filed antidumping (AD) and countervailing duty (CVD) petitions against corrugated pizza box imports from China, Malaysia, and Türkiye. The petitions, filed simultaneously with the US Department of Commerce and the US International Trade Commission (USITC), allege dumping margins as high as 568.5% for China.
For food-service brands, pizzeria chains, importers and packaging buyers, this is not a distant legal proceeding. If the cases advance, importers of record — not foreign exporters — bear liability for the duties, and deposits can attach as early as the preliminary determinations in early-to-mid 2027. Here is what the petitions cover and how supply chain teams should respond.
What Was Filed
The petitions target "unfairly traded" corrugated pizza boxes that the petitioners claim have surged into the US market at prices below fair value, injuring domestic producers. The allegations break down by country:
| Country | Case Type | Alleged Dumping Margin |
|---|---|---|
| China | Antidumping (AD) | 92.62% – 568.50% |
| Malaysia | Antidumping (AD) | 110.73% |
| Türkiye | AD + Countervailing (CVD) | 120.65% – 210.37% |
The Turkish CVD petition additionally alleges government subsidies — including tax breaks and discounted raw materials — and cites evidence of cross-border subsidies from the Russian government benefiting Turkish producers. The petitioners report that subject imports grew by 130% from 2023 to 2025, with further increases in 2026, a surge they link to declines in US domestic production, shipments, profits and employment.
Dumping margins of this magnitude — if upheld — would effectively close the US market to the named-country product. Importers should not treat these as negotiating numbers.
Product Scope: What Is Actually Covered
The scope is broader than the name "pizza box" suggests. It covers certain corrugated food-service boxes, whether finished or unfinished, assembled or unassembled — including ready-to-assemble corrugated die-cut blanks shipped flat in bundles. Key parameters:
- Dimensions: length ≥ 5 inches, width ≥ 5 inches, height ≤ 4 inches (no maximum length or width).
- Flute types: B-, C-, D- and E-flute, and any equivalent corrugation.
- Finishing: printed or unprinted, coated or uncoated (including grease-resistant liners), with or without ventilation holes, perforations, or condiment holders.
- Shapes: rectangular, square, round, hexagonal or octagonal.
- HTSUS classification: typically 4819.10.0020 (though the written scope controls).
The Origin Rule That Matters Most
The petition defines country of origin as where the corrugated sheet is produced. Critically, boxes made from Chinese corrugated board that undergo further processing in a third country — printing, coating, die-cutting, trimming, folding or assembly — remain in scope. This means simple trans-shipment or light finishing in an unaffected country is not a lawful way around the duty. Genuine sourcing diversification requires genuine upstream (board manufacturing) diversification.
Timeline: When Duties Could Hit
Commerce is expected to initiate the investigations around September 29, 2026. The estimated schedule:
| Milestone | Estimated Date |
|---|---|
| Petitions filed | September 9, 2026 |
| Commerce initiates investigations | ~September 29, 2026 |
| USITC preliminary injury determination | ~October 26, 2026 |
| Commerce preliminary CVD determination (Türkiye) | December 3, 2026 – February 8, 2027 |
| Commerce preliminary AD determinations | February 16 – April 7, 2027 |
| Commerce final AD/CVD determinations | ~August 20, 2027 |
| USITC final injury determination | ~October 4, 2027 |
While final orders would come in late 2027, provisional cash deposits can be required from the preliminary determinations — and under suspension-of-liquidation rules, exposure can in some cases reach back ~90 days before the preliminary determination for entries of subject goods. Importers planning 2027 programs should price that risk in now.
What It Means for Buyers and Brands
- Price and supply shock. US domestic pizza box capacity is concentrated in the two petitioners. If imports from the three named countries are effectively removed, short-term supply will tighten and prices will rise before new capacity qualifies.
- Liability sits with the importer. AD/CVD duties and deposits are the importer of record's obligation — often well after goods are ordered. Contracts need duty clauses, and suppliers' origin claims need documentation, not assurances.
- "Third-country assembly" is a trap, not a strategy. Because origin follows the corrugated sheet, routing Chinese board through another country for printing or die-cutting does not escape the scope and can create separate customs fraud exposure.
- Diversification must be structural. Buyers should validate where board is actually laminated, not just where boxes are converted. Supply bases in regions outside the named countries — with board manufactured locally — offer the durable option.
- The trade-remedy map is widening. This petition follows years of AD/CVD and Section 301 action across packaging and paper categories. A sourcing strategy tied to a single country or factory is increasingly a compliance and continuity risk in itself.
The Great Union Perspective
Our clients across North America and Europe increasingly ask us not for the cheapest box, but for a supply base they can trust when trade policy shifts overnight. Great Union's network spans qualified manufacturing partners across mainland China and Southeast Asia, with board sourcing, converting, QC and logistics coordinated end to end. When a product category faces trade action, we help brands re-map their corrugated and paperboard programs to verified, board-level origins — with documentation that holds up at customs.
If your pizza boxes, food-service corrugated or related paperboard packaging currently originate in China, Malaysia or Türkiye, the window to review and diversify is before preliminary determinations reshape pricing and lead times. We can help you audit origin exposure and build a compliant, multi-origin supply plan.

2026年9月9日，由包装行业巨头 Smurfit Westrock（斯穆菲·韦斯特罗克）和 Pratt Industries（普拉特工业）组成的"美国披萨盒制造商联盟"，联合美国钢铁工人联合会，向美国商务部和美国国际贸易委员会（USITC）同时提交申请，要求对来自中国、马来西亚和土耳其的瓦楞披萨盒征收反倾销税（AD），并对土耳其产品加征反补贴税（CVD）。申请书中主张的最高倾销幅度，中国高达 568.5%。
对餐饮品牌、披萨连锁、进口商和包装采购方而言，这不是一场遥远的法律程序。一旦案件推进，承担关税责任的是美国进口记录人（importer of record），而非国外出口商；最早在2027年上半年初裁阶段，海关就可能开始征收保证金。下面拆解申请内容、时间线以及供应链团队该如何应对。
申请内容是什么
申请针对"不公平贸易"的瓦楞披萨盒，主张这些产品以低于公允价值的价格大量涌入美国市场，对本土产业造成损害。各国指控情况如下：
| 国家 | 案件类型 | 主张倾销幅度 |
|---|---|---|
| 中国 | 反倾销（AD） | 92.62% – 568.50% |
| 马来西亚 | 反倾销（AD） | 110.73% |
| 土耳其 | 反倾销 + 反补贴（AD/CVD） | 120.65% – 210.37% |
针对土耳其的反补贴申请还指控其获得政府补贴（包括税收减免和低价原材料），并提到有证据显示俄罗斯政府向土耳其生产商提供了跨境补贴。申请人称，被调查产品进口量在 2023至2025年间增长了130%，2026年还在进一步上升，并将其与美国本土产量、出货量、利润和就业的下滑挂钩。
如此量级的倾销幅度一旦被裁定成立，等于从法律上关闭涉案国家产品进入美国市场的大门。进口商不应把这些数字当作谈判筹码。
产品范围：到底覆盖哪些产品
实际范围比"披萨盒"这个名字更宽。它涵盖特定瓦楞餐饮食品盒，无论成品还是半成品、已组装还是未组装——包括以平板捆装形式进口的即折瓦楞刀模版（die-cut blanks）。关键参数：
- 尺寸：成品长≥5英寸、宽≥5英寸、高≤4英寸（长宽无上限）。
- 瓦楞类型：B楞、C楞、D楞、E楞及任何等效瓦楞。
- 表面处理：无论是否印刷、是否涂层（包括防油内衬）、是否带透气孔/易撕线/酱料托。
- 形状：长方形、正方形、圆形、六边形或八边形均在范围内。
- 税号：通常归入 4819.10.0020（最终以书面范围描述为准）。
最关键的原产地规则
申请书将原产地定义为瓦楞纸板的生产地。更重要的是：用中国瓦楞纸板制成、再在第三国进行印刷、涂油、模切、修边、折叠或组装等加工的盒子，仍在调查范围内。这意味着，把中国纸板运到非涉案国家做简单加工或转口，不能合法规避关税。真正的供应链多元化，必须是上游（纸板制造）层面的多元化。
时间线：关税可能何时落地
美国商务部预计在 2026年9月29日前后正式立案。预估流程如下：
| 节点 | 预计时间 |
|---|---|
| 提交申请 | 2026年9月9日 |
| 商务部正式立案 | 约2026年9月29日 |
| USITC 初裁（产业损害） | 约2026年10月26日 |
| 商务部反补贴初裁（土耳其） | 2026年12月3日 – 2027年2月8日 |
| 商务部反倾销初裁 | 2027年2月16日 – 4月7日 |
| 商务部 AD/CVD 终裁 | 约2027年8月20日 |
| USITC 终裁（产业损害） | 约2027年10月4日 |
虽然最终征税令要到2027年底，但从初裁起海关就可要求缴纳临时现金保证金；而且根据"中止清算"规则，在某些情况下对涉案货物的追征可回溯至初裁前约90天。正在规划2027年采购计划的进口商，现在就应把这一风险计入成本。
对采购方和品牌意味着什么
- 价格与供应双重冲击。美国本土披萨盒产能高度集中在两家申请人手中。若三国进口被实质挤出，在新产能合规补位前，短期供应将收紧、价格将上涨。
- 责任在进口商。反倾销/反补贴税及保证金是美国进口记录人的义务，且往往在下单很久之后才产生。合同必须加入关税条款，供应商的原产地声明要有文件支撑，而非口头承诺。
- "第三国组装"是陷阱不是策略。由于原产地跟随瓦楞纸板，把中国纸板转到他国印刷或模切，不但逃不出调查范围，还可能构成海关欺诈风险。
- 多元化必须是结构性的。采购方应核实纸板真正的复合/生产地，而不只是盒子在哪家厂成型。在非涉案国家、且纸板本地生产的供应基地，才是可持续选项。
- 贸易救济版图正在扩大。此案是多年来包装纸品类一系列双反和301关税行动的延续。把采购绑定在单一国家或单一工厂，本身就越来越是一种合规与断供风险。
佳合香港的观点
我们在北美和欧洲的客户越来越多地要的不是"最便宜的盒子"，而是一个在贸易政策一夜生变时依然靠得住的供应体系。佳合香港的合作网络覆盖中国大陆与东南亚的合格制造伙伴，纸板采购、成型、QC与物流端到端协同。当某一品类遭遇贸易行动时，我们帮助品牌把瓦楞和纸板盒项目重新映射到经核实的、纸板层面的原产地——并提供经得起海关核查的文件。
如果您的披萨盒、餐饮瓦楞包装或相关纸板盒目前产自中国、马来西亚或土耳其，审视和多元化供应链的窗口期，是在初裁重塑价格与交期之前。我们可以帮您审计原产地敞口，搭建合规的多产地供应方案。
