US Customs and Border Protection enforcement has reached unprecedented levels. For international freight forwarders managing shipments into the United States, the compliance landscape has never been more demanding or the consequences of mistakes more severe. What was once a manageable cost of doing business has become an existential risk for forwarders who do not take US customs regulations seriously.

This guide covers the key enforcement trends, the areas where penalties are hitting hardest, and the concrete steps international forwarders can take to protect their shipments and their clients.

Record Enforcement Numbers

The numbers tell an unmistakable story. CBP recovered $192.77 million in penalties and fines in the first half of 2025 alone. That is not a yearly figure. That is six months of enforcement activity. To put it in perspective, this pace represents a significant acceleration from prior years and signals a clear policy direction: the US government is investing heavily in customs enforcement and expects that investment to produce results.

More than 1,400 penalty actions were issued in just the first half of 2025, covering everything from classification errors and valuation discrepancies to forced labor violations and security filing failures. CBP has also increased its targeting of repeat offenders. If your operation has been flagged once, the scrutiny on your subsequent shipments intensifies dramatically. First-time violations that might have resulted in a warning letter five years ago now carry immediate financial penalties.

Where Penalties Hit Hardest

Understanding where enforcement is concentrated helps you focus your compliance efforts where they matter most. The data reveals four primary areas where international forwarders are most vulnerable.

HTS misclassification accounts for approximately 42% of all customs penalties. The Harmonized Tariff Schedule contains over 17,000 individual product codes, and selecting the wrong one can result in incorrect duty payments, which CBP treats as either negligence or fraud depending on the circumstances. Even honest mistakes can trigger penalties of $5,000 to $10,000 per entry, and if CBP determines that misclassification was a pattern rather than an isolated error, penalties can reach $100,000 or more per violation.

UFLPA (Uyghur Forced Labor Prevention Act) violations have become a major enforcement priority. Since the act went into full effect, CBP has detained and seized shipments worth hundreds of millions of dollars that could not demonstrate compliance with forced labor prohibitions. Any goods with supply chain connections to the Xinjiang region of China face a rebuttable presumption of forced labor, and the burden of proof falls entirely on the importer. International forwarders who do not understand UFLPA requirements are putting their clients at serious legal and financial risk.

AD/CVD (Antidumping and Countervailing Duty) enforcement continues to be aggressive. These duties can add 50% to 300% or more to the landed cost of goods, and CBP is actively pursuing importers who attempt to evade them through transshipment, misclassification, or undervaluation. Penalties for AD/CVD evasion are among the highest in customs enforcement, often exceeding the value of the goods themselves.

ISF (Importer Security Filing) non-compliance remains a persistent problem. The 10+2 filing requirement mandates that importers submit detailed shipment information at least 24 hours before cargo is loaded onto a vessel bound for the US. Late filings, inaccurate data, or missing filings result in penalties of $5,000 per violation, and CBP has shown no signs of reducing enforcement in this area. For forwarders managing dozens of shipments simultaneously, ISF compliance requires disciplined processes and reliable systems.

47 Agencies at the Border

One of the most underappreciated challenges of US import operations is that CBP is not the only agency you need to worry about. There are 47 federal agencies with authority to regulate, inspect, hold, or seize goods at the US border. Each has its own requirements, filing deadlines, and enforcement mechanisms.

The FDA (Food and Drug Administration) regulates food products, pharmaceuticals, medical devices, and cosmetics. Prior notice filings must be submitted before arrival, and FDA holds can add days or weeks to your delivery timeline. The USDA (Department of Agriculture) enforces plant and animal health regulations that can result in fumigation requirements, laboratory testing, or outright refusal of entry. The EPA (Environmental Protection Agency) regulates chemicals, pesticides, and certain manufactured goods. The CPSC (Consumer Product Safety Commission) can detain and destroy products that do not meet US safety standards. The FCC (Federal Communications Commission) regulates electronic devices. The TTB (Alcohol and Tobacco Tax and Trade Bureau) controls imports of alcoholic beverages and tobacco products.

Cross-agency holds are increasing in frequency. A single shipment can be flagged simultaneously by CBP for classification review, by FDA for prior notice issues, and by CPSC for product safety testing. Each hold operates independently, meaning you must resolve every agency's concerns before your cargo is released. For international forwarders who are not deeply familiar with multi-agency compliance requirements, these cascading holds can turn a routine shipment into a weeks-long nightmare of delays, storage charges, and frustrated clients.

The C-TPAT Advantage

In an environment of heightened enforcement, C-TPAT (Customs-Trade Partnership Against Terrorism) certification has become more valuable than ever. C-TPAT is a voluntary partnership program between CBP and the trade community that recognizes companies with robust supply chain security practices.

The benefits are tangible and significant. C-TPAT certified importers receive fewer physical examinations of their cargo, which means faster processing times and lower risk of demurrage charges. They receive priority processing during periods of heightened security. They gain access to the FAST (Free and Secure Trade) lanes at land border crossings. And perhaps most importantly, they receive a reduction in their risk assessment score, which influences how CBP targets shipments for inspection.

How to Protect Your Shipments

Protecting your shipments in this enforcement environment requires a multi-layered approach. There are no shortcuts, and there is no substitute for working with people who understand US customs regulations at a deep operational level.

First and foremost, work with a CBP Licensed Customs Broker. This is non-negotiable. A licensed broker has passed one of the most rigorous professional exams in the industry and is held to ongoing compliance standards by CBP. They understand the nuances of tariff classification, valuation methods, and regulatory requirements that unlicensed agents simply do not.

Classify your HS codes properly and proactively. Do not wait until a shipment is at the port to determine the correct classification. Work with your broker to establish binding rulings on your most common product categories. Invest the time upfront to get classifications right, because correcting them after the fact is exponentially more expensive when penalties are involved.

File ISF on time, every time. The 24-hour advance filing requirement is absolute. Build ISF preparation into your standard operating procedure so that it happens automatically as part of your booking process, not as an afterthought once the vessel has already sailed. Late ISF filings are among the easiest penalties for CBP to issue because the violation is binary: you either filed on time or you did not.

Maintain meticulous documentation. Every commercial invoice, packing list, bill of lading, and certificate of origin should be reviewed for accuracy before submission. Documentation discrepancies are one of the primary triggers for CBP examinations, and once an examination is ordered, it cannot be reversed. The time and cost of resolving document-related holds far exceeds the effort required to get documents right the first time.

Finally, use a C-TPAT certified partner for your US operations. The risk reduction that comes with C-TPAT certification is not just theoretical. It translates directly into fewer inspections, faster clearance, and lower total costs. In a market where CBP is issuing more penalties than ever before, every advantage matters.

Enforcement Will Only Increase

Every indicator suggests that US customs enforcement will continue to intensify in the coming years. CBP is investing in AI-powered risk assessment tools, expanding its partnership with other government agencies, and hiring more enforcement personnel. The political environment in the US supports aggressive trade enforcement regardless of which party holds office. Forced labor enforcement under UFLPA will continue to expand. AD/CVD enforcement will remain a priority. And the overall penalty structure will only become more punitive for repeat offenders.

For international freight forwarders, the message is clear: compliance is not a cost center. It is a survival requirement. The forwarders who will thrive in this environment are the ones who partner with experienced, certified US operations teams that understand the rules, respect the deadlines, and have the relationships to resolve problems before they become penalties.
