Impact of Customs Clearance Delays on Global Shipping Time

  • January 2, 2025

Global shipping underpins international trade, ensuring goods move smoothly across borders. However, time remains a critical trade barrier. Hummels (2001) found that each additional day in transit reduces the likelihood of the U.S. importing a manufactured product by 1.5%. Customs clearance delays, driven by incomplete documentation, regulatory issues, and inspections, further disrupt delivery schedules and create supply chain inefficiencies. 

Keep reading and explore the causes of freight clearance delays, the customs process itself, and strategies shippers can use to avoid and mitigate these disruptions.

What Causes Customs Clearance Delays in Global Shipping?

Freight clearance delays can occur for various reasons, many of which are preventable with the proper preparation and understanding of the process.

Reason #1 - Complexity of Regulations 

One of the most common reasons for freight delays is the complexity of regulations across different countries. Freight regulations vary significantly depending on the shipment’s origin, destination, and type of goods. For instance, a shipment sent via logistics major carriers may encounter different inspection requirements depending on the destination country's import laws. These variances make compliance challenging and lead to delays when shippers fail to meet the requirements.

Reason #2 - Lenghty Risk Assessments

Additionally, shipments are often flagged for random inspections or based on risk assessments by customs officers. Factors such as declared value, type of goods, and shipping route can influence whether a shipment is chosen for closer scrutiny. Although these inspections are necessary to ensure compliance with local laws, they can significantly slow down the clearance process.

Reason #3 - Missing or Inaccurate Documentation

Incomplete or inaccurate documentation is another leading cause of freight interruptions. Customs officers verify shipments using documents such as commercial invoices, packing lists, and certificates of origin. Missing or incorrect details—such as product descriptions or declared value discrepancies—can trigger inspections and lead to further interruptions.

Failure to file specific documents, such as an Importer Security Filing (ISF) for shipments to the U.S., can also result in penalties and clearance delays. These administrative setbacks can cause days, or even weeks, of delivery delays, leading to customer dissatisfaction and financial losses for businesses.

Reason #4  - Regulatory Issues and Tax Compliance

Shipments can be delayed if duties and taxes haven’t been paid or customs officers suspect an undervaluation of goods to avoid taxes. For example, declaring a shipment’s value lower than its actual worth may result in the package being held until the correct valuation is confirmed. Similarly, shipping restricted or prohibited items without proper documentation can result in significant interruptions, fines, or even seizure of goods.

How Do Customs Clearance Processes Affect Shipment Delivery?

Understanding the intricacies of the border clearance process is essential to understanding the impact of freight clearance delays.

Understanding the Customs Clearance Process

Freight clearance is critical in international shipping, ensuring that goods comply with the destination country's regulations. The process involves several stages:

  1. Document Submission: Required documents, such as commercial invoices, packing lists, and permits, are submitted to authorities.
  2. Payment of Duties and Taxes: Import duties and taxes must be calculated and paid based on the shipment’s declared value.
  3. Inspections: Shipments may be inspected to verify compliance with customs declarations.

Leading logistics providers often facilitate the freight clearance process, but errors in documentation or payments can delay shipment clearance.

Impact on Delivery Timelines

When a shipment is delayed at customs, delivery timelines are inevitably extended. These delays can have ripple effects for time-sensitive shipments, impacting supply chain efficiency and customer satisfaction. For businesses, delays may result in additional costs, such as customs warehouse storage fees or non-compliance penalties. These delays are particularly disruptive for industries relying on just-in-time deliveries, where minor disruptions can lead to significant losses.

What Can Shippers Do to Avoid Customs Clearance Delays?

While freight clearance delays are often inevitable, shippers can take several proactive measures to reduce the likelihood and impact of these disruptions.

Implementing Best Practices for Documentation

Ensuring accurate and complete documentation is the most effective way to avoid freight clearance delays. This includes:

  • Commercial Invoices: Ensure invoices contain detailed and accurate product descriptions, declared values, and HS (Harmonized System) codes.
  • Packing Lists: Verify that the packing list matches the shipment contents and includes weights and dimensions.
  • Permits and Certificates: Include any necessary import permits, certificates of origin, or other required documentation.

Shippers should double-check all paperwork before submission, as minor errors can trigger delays.

Ensuring Timely Compliance with Duties and Taxes

Paying duties and taxes upfront can help avoid delays. Carrying tools allow shippers to calculate and pay these fees before the shipment reaches customs. Prepayment ensures shipments can move through clearance procedures without waiting for payment processing.

Engaging Customs Brokers

Customs brokers are professionals who specialize in navigating customs regulations. They can assist shippers with document preparation, compliance checks, and communication with customs authorities. Partnering with a reliable customs broker ensures a smoother freight clearance process, reducing the risk of delays.

Preparing Shipments for Smooth Clearance

Proper preparation of shipments is crucial to avoid delays. Key steps include:

  • Ensuring shipments are correctly labeled with accurate product descriptions and HS codes.
  • Packaging goods securely to minimize the likelihood of damage during transit and inspection.
  • Including all relevant documentation with the shipment to prevent delays caused by missing paperwork.

Providing additional documentation and ensuring compliance with destination country regulations is essential for restricted or high-risk items.

What Should You Do If Your Shipment is Stuck in Customs?

Despite best efforts, shipments can still get delayed at customs. Knowing how to handle these situations is critical to resolving issues quickly.

Steps to Resolve Delays

If your shipment is delayed, contact the carrier or freight forwarder first. The tracking page provides real-time updates on shipment status and reasons for delays. Identifying the issue—whether it’s missing documentation or an inspection—is key to addressing it promptly.

Next, provide any additional information or documentation requested by authorities. This could include corrected invoices, permits, or certificates of origin. Acting quickly can prevent further delays and extra fees.

Leveraging Freight Forwarders

Freight forwarders often have established relationships with customs authorities and can expedite the clearance process. They can guide shippers through resolving issues and ensure that shipments are cleared through customs efficiently.

Why Do Delays Occur with Major Carriers?

Even reliable carriers face customs delays due to incomplete paperwork, restricted items, and destination-specific regulations. Understanding these challenges can help shippers avoid potential disruptions and ensure timely deliveries.

Challenges Faced by Carriers

Carriers encounter freight delays for various reasons, such as:

  • Incomplete Customs Declarations: Missing details in customs declarations can cause packages to be flagged for review.
  • Restricted Items: Shipping restricted or prohibited items without the necessary permits can lead to prolonged inspections or confiscation.
  • Destination-Specific Regulations: Some countries have stricter customs requirements, causing shipments to face additional scrutiny.

How Carriers Assist Shippers

Major carriers provide tools and resources to help shippers avoid delays, such as freight support services, document preparation, duty payment options, real-time tracking, and customer support to resolve customs issues quickly.
