Online shopping offers incredible convenience, opening up a world of products right at your fingertips.

Understanding how customs clearance works and what causes Customs Delays can help ensure a smooth shipping experience from checkout to your front door.
This guide will walk you through the common reasons for import customs clearance delays and provide simple, actionable tips to help you avoid them. We want you to receive your packages quickly, with customs clearance in progress kept to a minimum, and without any surprises.
Customs offices in every country are responsible for inspecting incoming goods. They ensure that all items entering the country are legal, safe, and that the correct taxes are paid. These may include duties, VAT, OPT, and other applicable charges. A customs clearance delay can occur for several reasons, often linked to how shipments are processed and the information provided.
One common reason for customs clearance delays is a shortage of customs staff. When there aren’t enough officers available—especially during peak periods—a large amount of imports can quickly create a backlog. Checking and clearing each product takes time, and completing the customs clearance process for all packages may not be possible within a single day.
Shipments might be held up simply because they are waiting their turn for inspection during customs clearance in progress.
During busy seasons, customs teams are stretched thin, which extends processing times and increases the chance of import customs clearance delays.
Customs clearance delays often become more frequent during festival seasons or high-volume shopping events such as Amazon Prime Day, Black Friday, Cyber Monday, Thanksgiving, Christmas, or other major sales. When a surge of shipments arrives, customs must process significantly more packages than usual, slowing the entire process. As a customer, it's important to plan ahead and anticipate that customs clearance in these seasons may take longer. Factoring in the potential for clearance delays during high-demand periods will help you set more realistic expectations for your delivery.
To keep your shipment moving and minimise a customs clearance delay, make sure to pre-alert your package with your shipping company—like aeropost—before it arrives at the fulfillment center in Miami. Pre-alerting helps the team quickly determine the accurate package value and move your order forward. Otherwise, extra time may be needed in the country to verify product details and values, which can lead to clearance delays.
Providing an invoice with your shipment is also crucial. Without a pre-alert or a clear invoice, customs officials may have to estimate your package’s value. This sometimes results in an assigned duty that is higher than what you expect, leading to higher clearance costs.Every international shipment requires a valid commercial invoice that clearly outlines what’s inside, its true value, and who sent it. Packages missing this information, or containing vague or incorrect details, are likely to face delays as customs officers work to clarify the shipment during the clearance process.
A proper supplier invoice must include:Shipper’s name or company logo
Consignee’s full name and address
Detailed description of the items
Value of each item
Subtotal and total amount paid
It’s also important that the invoice is clear, readable, and preferably provided in PDF format to avoid errors during processing.
Common documentation errors include:Missing or unclear invoices
Vague item descriptions (e.g., “gift” instead of “men’s cotton shirt”)
Incorrect or incomplete contact information for the sender or receiver
Ensuring that all documentation is complete, accurate, and properly formatted is essential to avoid unnecessary customs clearance delays.

It can be tempting to declare a lower value to pay less in import duties. However, customs officers have methods to assess actual values. If they believe your item has been undervalued, your package can be held until the correct value is confirmed, resulting in a customs clearance delay. You may also end up paying additional duties or incur penalties for false declarations. Declaring the true value—and including a copy of your purchase receipt —is the best way to avoid unexpected delays and costs throughout customs clearance.

Every country restricts or prohibits the import of specific items. Prohibited goods are not allowed, while restricted goods may require special permits. Examples include firearms, flammable liquids, agricultural products, certain batteries, and prescription medication.
Attempting to ship these items without proper documentation can lead to Customs Delays or even confiscation of your package.Now that you know what causes customs clearance delays, let's focus on how to prevent them. A few simple steps can make a big difference in how quickly you receive your online orders from popular U.S. stores like Amazon, Walmart, Best Buy, and Target.
Provide Accurate and Detailed Information
When you place an order with sites such as Amazon, Walmart, or Shein, make sure your shipping information is complete and correct. More importantly, ensure the seller provides a detailed commercial invoice for the shipment. The description of the items should be specific.
Declare the True Value of Your Goods
Always declare the actual price you paid for your items, whether shopping from Amazon, Walmart, or other U.S. stores. Include a copy of the purchase receipt with your shipment. This proves the value you’ve declared is accurate and helps build trust during import customs clearance.
While it might seem like you're paying more in duties upfront, you will save yourself from the headaches of customs clearance delays, re-evaluations, and potential fines. It’s the easiest way to keep your shipment moving and minimize the chances of a clearance delay.Check for Restricted and Prohibited Items
Before you click "buy" on Amazon, Walmart, eBay, Best Buy, or other stores, take a moment to check your country's list of restricted and prohibited items to avoid issues during customs clearance. This information is usually available on your local customs agency's website. Many online retailers also have shipping restrictions for certain products to specific countries.
If you’re using a package forwarding service, they often provide a clear list of items they cannot ship. For example, things like aerosols, perfumes, and certain electronics with large batteries are often flagged. Checking this list beforehand can save you from purchasing an item that can’t be shipped to you and reduce the risk of a customs clearance delay.Choose a Reliable Shipping Partner
Using a trusted and experienced shipping service can make all the difference. Reputable couriers and package forwarders understand customs clearance requirements for different Caribbean countries. They can help ensure your paperwork is correct and guide you on what you can and cannot ship—no matter which store you order from, including Amazon, Walmart, or Best Buy.
