U.S. Customs Compliance FAQ: Essential Answers Every Importer Needs
U.S. Customs compliance is no longer just a box to check—it’s one of the biggest operational risks importers face today. Enforcement agencies are moving aggressively on multiple fronts:
-
Uyghur Forced Labor Prevention Act (UFLPA) enforcement continues to expand, with entire categories of goods facing heightened scrutiny.
-
De minimis treatment is effectively disappearing, eliminating what many importers once relied on as a low-value loophole.
-
Antidumping and countervailing duties (AD/CVD) now cover a broader range of products, increasing the likelihood that even routine shipments face tariff exposure.
-
Partner Government Agencies (PGAs) are coordinating more closely with Customs, tightening inspections and compliance requirements across industries.
This FAQ covers the questions importers ask us most often and provides practical, plain-English guidance to minimize compliance risks. Whether you’re a seasoned importer or just starting to expand into international trade, these insights will help you navigate the increasingly complex U.S. customs landscape.

常见问题解答
Classification and Duties
1. How do I make sure my products are classified correctly under the Harmonized Tariff Schedule?
根据《协调关税表》进行商品分类将决定关税税率、保税仓储要求及执法风险。请记录分类依据，保留既往裁定函以便查阅，当商品分类存在疑义时，建议在发货前向海关申请约束性裁定以确保确定性。
2. What are antidumping and countervailing duties (AD/CVD)?
反倾销税适用于低于公平价值销售的商品；反补贴税则针对外国政府补贴。税率可超过300%，且常具有追溯效力。请谨记：进口商（而非供应商）承担责任，忽视反倾销/反补贴风险是摧毁利润率的最快途径之一。
3. What about other special tariffs like Section 301 or Section 232?
除反倾销/反补贴调查外，还需考虑针对中国商品的301条款关税、钢铁铝材的232条款关税以及各类配额限制。这些因素可能大幅改变到岸成本。请定期更新报价和合同条款，避免承担意外关税账单。
4. How do I determine the correct customs value of my goods?
海关价值不仅限于发票价格。必要时需计入辅助成本、模具费用、设计工作及特许权使用费。关联方定价需接受额外审查。一份简短的估值备忘录，详细记录评估方法及预期年终调整，在审计期间将发挥重要作用。
Origin and Marking
5. What are the rules for country-of-origin marking?
所有进口商品必须永久标注原产国，除非获得特别豁免。美国海关与边境保护局（CBP）采用实质性转变等测试标准——仅凭供应商声明不足以证明。标识错误或缺失将导致货物扣留、罚款及高昂的强制重新贴标费用。
6. What is the difference between Made in U.S.A. and country-of-origin marking?
原产国标识是美国海关与边境保护局（CBP）对进口商品的强制要求，用于标明产品制造地。"美国制造"属于联邦贸易委员会（FTC）监管的营销声明，其国内成分标准更为严格，要求"全部或几乎全部"采用本土原料。
Partner Government Agencies
7. What other U.S. agencies regulate imports beyond CBP?
美国海关与边境保护局（CBP）负责执行包括美国食品药品监督管理局（FDA）、美国消费品安全委员会（CPSC）、美国环境保护署（EPA）、美国农业部（USDA）及美国联邦通信委员会（FCC）在内的合作政府机构（PGAs）的法规。货物即使通过海关清关，仍可能被合作政府机构拦截。请在采购流程初期明确相关要求，并在可能的情况下获取预先许可。
Documentation and Procedures
8. How important is documentation alignment?
文件一致性至关重要。发票、装箱单、提单和采购订单必须内容一致。诸如"零件"或"样品"等模糊描述属于警示信号，会触发审查。保持文件一致性可减少货物滞留，加速放行流程。
9. What happens if my shipment is detained by CBP?
扣留情况日益普遍。海关边境保护局将要求提供补充信息——快速、详尽的答复可解决多数扣留问题。若涉及原产地、商品分类或涉嫌反倾销/反补贴税违规，则需更长的解决周期。请预先制定响应方案并确定决策人。
10. What are the risks if I fail to comply with Customs laws?
违规操作将导致延误、仓储费、罚款、扣押、追溯关税，严重时甚至面临刑事调查。美国海关与边境保护局现将反复出现的"文书错误"视为系统性合规缺陷的标志，而非孤立失误。
Corrections and Record-Keeping
11. Can I fix compliance problems after a shipment has been imported?
有时。可用的工具包括进口后修改、抗议和自愿事先披露。然而，在货物运输后处理问题总是比在货物运输前发现问题更昂贵、风险更高。
12. How long must I keep import records?
自入账之日起，须将发票、合同、技术规范、裁定函、实验室报告、PGA申报文件及经纪人通信记录保存五年。条理清晰的文件是您在海关边境保护局审计期间的最佳保障。
13. How do I stay updated on changes in Customs regulations?
定期关注美国海关与边境保护局（CBP）官网动态，订阅贸易法规通讯，加入相关行业协会，并与经验丰富的贸易法律顾问保持合作。法规更新速度极快——仅依赖供应商或代理商提示问题远远不够。
Broker and Bond Management
14. What are best practices for managing customs brokers?
虽然报关行负责提交报关单，但法律责任仍由进口商承担。需提供清晰的书面操作指南，定期审核报关单，并实施周期性审计。针对商品分类、估价、原产地及PGA（产品原产地保证）问题，应建立升级处理流程。
15. What is a customs bond and when do I need one?
海关担保确保美国海关与边境保护局（CBP）能收到应缴的关税、税款及费用。价值超过2,500美元的商业货物大多需要担保。偶尔进口时可使用单次进口担保，全年持续进口则需办理年度持续进口担保。
16. What is the difference between formal and informal entry?
价值超过2,500美元的大多数商业进口货物需办理正式报关手续，并需提供海关担保。低价值货物可采用简易报关方式，要求较少，但并非所有货物都符合简易处理条件。
Special Programs and Procedures
17. What are the benefits of programs like C-TPAT?
加入C-TPAT计划可减少货物检查次数、加快通关速度，并降低在海关边境保护局（CBP）的风险评级。虽然该计划要求企业切实投入供应链安全措施，但它向CBP传递了您是值得信赖的贸易伙伴的信号。
18. Is technology worth the investment in Customs compliance?
当然。分类数据库、合规管理平台和自动化的ISF申报工具能减少人为失误，并生成完整的审计追踪记录。对于高进口量的企业而言，人工操作流程存在重大风险。
19. What about the de minimis rule?
第321条最低限额规则历来允许价值低于800美元的货物免税入境，现正经历重大变革。 新规已基本取消了对多数商品的免税待遇，尤其是来自中国及电子商务渠道的商品。自2025年8月29日起，进口商必须为原先免税的货物办理正式入境手续并缴纳相应关税。此项调整堵住了关键漏洞，无论货物价值高低，都将提升所有进口商的风险等级。
Trade Agreements and Special Cases
20. How do free trade agreements affect my imports?
诸如《美墨加协定》之类的协议可降低或免除符合条件商品的关税。但企业必须严格遵守原产地规则并完整保留相关文件。错误的优惠申报将导致关税账单、罚款及未来优惠资格丧失。
21. What is duty drawback?
退税退费计划可退还高达99%的进口关税、税费及附加费，适用于后续出口或销毁的进口货物。制造商若出口含有进口零部件的成品，却未提交退税申请，往往会错失可观的退费机会。
Customs Audits and Enforcement
22. What happens during a CBP audit?
海关边境保护局（CBP）可追溯审查长达五年的进口申报记录，重点核查商品分类、估价、原产地及PGA合规性。清晰的文件记录与书面决策依据既能降低潜在处罚风险，亦可彰显企业合规合规的善意努力。
23. What should I do if CBP seizes my goods?
立即采取行动——您通常只有30天时间申请救济。可选方案包括行政请愿、协商和解或司法诉讼。请立即聘请合格的法律顾问，以保留所有可行方案。
24. How does CBP enforce intellectual property rights?
美国海关与边境保护局每年查获数百万件假冒和侵权商品，按零售价计算价值达数十亿美元。进口商在运输侵权产品时，将面临货物扣押、巨额罚款，并常遭权利人提起民事诉讼。
Current Hot-Button Issues
25. What is the Uyghur Forced Labor Prevention Act (UFLPA)?
《美国新疆强迫劳动预防法》确立了一项可反驳的推定，即中国新疆地区的商品系使用强迫劳动生产，并禁止其进口。进口商必须提供清晰且具有说服力的证据以推翻该推定，通常需要完成完整的供应链追溯并获得独立第三方验证。
26. What is an Importer Security Filing (ISF) and when is it required?
国际安全申报（ISF，通常称为“10+2”）必须在船舶装货前至少24小时提交。对于远洋运输，逾期、不完整或不准确的申报将触发最高5,000美元/次的罚款，并可能导致货物滞留。请与您的报关行和货运代理密切协作，确保申报及时准确。
27. How do I handle temporary imports and ATA Carnets?
对于贸易展览、产品演示或维修活动，可使用ATA单证册或临时进口保证金凭证将货物免征关税入境，前提是这些货物须在一年内重新出口。若未能在期限内完成再出口，可能导致全额征税、罚款及保证金追偿。
关键要点
Compliance is a core business function, not just paperwork. Make customs compliance an integral part of your supply chain strategy, not an afterthought.
Master the fundamentals on every entry: classification, valuation, origin determination, and documentation accuracy form the foundation of successful importing.
Build defensive strength through binding rulings, meticulous recordkeeping, compliance technology, C-TPAT participation, and effective broker oversight.
Prepare for ongoing regulatory changes, including the elimination of de minimis benefits and intensifying UFLPA enforcement.
Develop operational playbooks for handling detentions and audits so compliance issues don’t paralyze your operations.

As UFLPA enforcement intensifies and the de minimis rule is transformed, the regulatory environment is more challenging than ever.
But U.S. Customs challenges also present an opportunity. Your customs compliance can be a competitive advantage. By mastering the fundamentals, anticipating regulatory shifts, and building a robust compliance program, you can protect your supply chain from disruptions, secure your profit margins, and stay ahead of the enforcement curve.
