When Do E-commerce Shipments Get Stuck at Customs? Common Scenarios to Avoid 

Introduction

It’s a frustrating reality for many e-commerce businesses: You’ve done everything right—picked, packed, shipped—and then suddenly, your order disappears into a black hole marked “Held at customs.” 

In fact, as much as 20% of international e-commerce shipments face customs-related delays, costing time, money, and customer satisfaction. For small and mid-sized sellers, even one held package can impact ratings and future sales. 

Customs delays aren’t always avoidable, but many are preventable. This blog will walk you through the most common scenarios where shipments get stuck and what you can do to avoid them. Whether it’s documentation errors, seasonal traffic, or incorrect tariff codes, we’ll unpack the root causes—and share tips to keep your parcels moving and get them released from customs faster. 

What Is Customs Clearance?

Before an international shipment can enter or leave a country, it must pass through customs control—the governmental authority that checks for legal compliance. This process is called customs clearance, and it’s a crucial part of cross-border trade. 

Simply put, customs clearance ensures the goods you’re shipping are legal, properly documented, and duty-paid where applicable. 

Importance of Compliance

Compliance is non-negotiable in global trade. Missing documents, misclassified items, or underpaid taxes can trigger delays—or worse, seizures and fines. 

From declaring items at customs accurately to ensuring all paperwork aligns with import/export rules, compliance helps speed up clearance and avoid red flags that hold up shipments. 

Key Players in the Clearance Process

Several parties play key roles in custom clearance service: 

  • Customs authorities: They inspect, assess, and decide whether to release, detain, or reject shipments. 
  • Freight forwarders: These intermediaries coordinate logistics, including transportation and documentation. 
  • Customs brokers: Experts in navigating complex clearance requirements and often essential for smooth processing. 
  • E-commerce sellers: Responsible for ensuring accurate product info, complete paperwork, and timely submission. 

 

Getting everyone on the same page is critical for a seamless shipping experience. 

Common Scenarios That Cause Customs Delays

Understanding the common causes of customs delays is the first step to preventing them. Here are the top culprits: 

Regulatory Issues

This is the #1 reason shipments get stuck. Common problems include: 

  • Incomplete documentation: Missing commercial invoices, packing lists, or certificates of origin can trigger automatic holds. 
  • Non-compliance: Incorrect labeling, missing safety certifications, or banned ingredients (especially for cosmetics, food, and electronics) can halt progress. 

 

One missed document can add days—or even weeks—to your timeline. For export or import, both sides must comply with their respective country’s regulations. 

Peak Seasons

During holidays and sales events like Black Friday, Christmas, or Lunar New Year, customs agencies deal with surging volumes. 

This overload creates bottlenecks in processing, even for shipments that are perfectly compliant. 

To make matters worse, courier services may also be stretched thin, causing further slowdowns in post-clearance delivery. Planning ahead is essential to minimize disruptions during peak seasons. 

Restricted or Prohibited Products

Some goods are restricted, regulated, or outright banned in certain countries. These include: 

  • Electronics with embedded batteries 
  • Herbal supplements and pharmaceuticals 
  • Perishable food items 
  • Cosmetics with specific chemicals 

 

Even if legal, these products may require special permits or advance declarations. Failure to comply can result in seizure or return to sender. 

Incorrect Tariff Codes

Using the wrong HS (Harmonized System) code can lead to: 

  • Incorrect duty calculations 
  • Customs disputes 
  • Delays while reclassifying 

 

This is especially common when sellers rely on automated systems without verifying the codes. A small mistake in classification can create major headaches down the line. 

Duties and Taxes

Another reason shipments may get stuck is due to unpaid or underpaid duties and taxes. 

If a shipment arrives and no payment has been arranged (or it’s incorrect), customs may hold the package until resolution. This also affects DDU (Delivery Duty Unpaid) shipments, where customers must pay on arrival—often causing confusion and delay. 

Random Inspections

Even compliant shipments can get flagged for random inspections under customs control. These are unplanned, often unavoidable, and typically add 24–72 hours to delivery. 

Although frustrating, random checks are part of the security process. Ensuring your paperwork is in perfect order helps minimize the impact. 

Controlling Authority Compliance for commercial Quantity Using Deminis Concept

When shipping goods in commercial quantities, customs authorities apply stricter compliance checks. Larger volumes raise flags for proper documentation, valuation accuracy, and regulatory adherence. Failing to meet these requirements can result in delays, penalties, or even shipment seizures under customs control. 

To navigate this, many e-commerce businesses leverage the de minimis concept. This refers to a threshold below which imported goods are exempt from duties and taxes. For instance, in the UAE, shipments valued under AED 1000 may qualify for duty-free entry. By structuring shipments to fall within these thresholds—especially for lower-cost items—businesses can reduce costs and speed up processing. 

Using de minimis effectively allows smoother custom clearance service, minimizes paperwork, and helps shipments get released from customs faster. However, it’s crucial to monitor changing regulations by country to stay compliant and avoid misuse. 

How to Avoid Customs Delays

While not every delay can be prevented, most can be mitigated by taking a few smart steps. Here’s how to stay ahead of the customs curve: 

Ensure Accurate Documentation

Double-check every document before shipping: 

  • Commercial invoices should include product description, value, origin, and HS code. 
  • Packing lists help customs verify contents without opening packages. 
  • Certificates of origin may be needed for specific trade agreements. 
  • Include recipient tax ID (especially in LATAM and Asia). 

 

Don’t forget digital copies—many modern systems require both electronic and physical documentation. 

Research Product Regulations

Every country has its own rules, and they change frequently. Stay informed by: 

  • Checking country-specific import restrictions 
  • Verifying labeling and packaging requirements 
  • Watching for product-specific red flags (like lithium batteries) 

 

Use customs websites or consult a broker to ensure your product isn’t unknowingly violating a regulation. 

Use Correct Tariff Codes

Use the official Harmonized System (HS) code directory to classify your products. If unsure: 

  • Ask your customs broker or freight forwarder for guidance. 
  • Cross-reference product attributes with official classifications. 
  • Avoid guessing—wrong codes can delay or overcharge duties. 

Partner with Experts

Working with a custom clearance service provider takes the pressure off your internal team. These professionals: 

  • Know regional customs rules 
  • Help you navigate paperwork 
  • Advocate for faster clearance 

 

For businesses scaling across borders, this partnership is often the key to consistency and reliability. 

Prepay Duties and Taxes

Choosing a DDP (Delivery Duty Paid) shipping model means the seller covers taxes upfront. This avoids surprises and speeds up delivery. 

Customers also appreciate not being asked to pay unexpected fees upon arrival, making for a smoother buying experience. 

Plan for Peak Seasons

Start early and ship early. Strategies include: 

  • Building in buffer time for customs delays 
  • Informing customers about potential slowdowns 
  • Avoiding the last-minute shipping crunch during major sales events 

 

Advance planning helps protect your reputation and keep delivery promises. 

Leverage Technology

Today’s shipping platforms and logistics software offer tools that help you: 

  • Automate customs documentation 
  • Track packages in real-time 
  • Flag compliance issues before they become problems 

 

Look for integrations with couriers and customs authorities to simplify the entire pipeline. These digital customs clearance solutions are worth the investment.
