Your parcel is stuck in US customs — here’s exactly why (and what to do)

Port congestion, random inspections, and paperwork gaps can freeze your package for weeks — here’s how to get it moving again.

Why is my parcel stuck in US customs for so long?

You tracked your parcel religiously, watched it sail across the Pacific, and then — nothing. It landed at the port on July 16 and has been sitting in “customs clearance” ever since. If this sounds familiar, you are far from alone.

US Customs and Border Protection (CBP) processes millions of shipments every single week. Under normal conditions, most commercial parcels clear within one to three business days. But “normal” has become increasingly rare. In recent months, shippers and receivers across the country — especially those routing through major California ports like Los Angeles and Long Beach — have reported delays stretching anywhere from one to three weeks, sometimes longer.

So what actually causes a parcel to get stuck? The short answer is: many things, and not all of them are within your control. US customs can hold a shipment for a routine random inspection (sometimes called an “exam hold”), for additional documentation, for commodity classification queries, or simply because the facility is overwhelmed with volume. Port congestion is a very real factor — when thousands of containers arrive faster than inspectors can process them, backlogs grow quickly.

The key thing to understand is that a delay does not automatically mean something is wrong with your parcel. It very often means the system is busy, and your shipment is sitting in a queue. That said, there are specific triggers that make certain parcels more likely to be flagged, and knowing them can help you avoid the problem on future shipments.

The most common reasons US customs holds international parcels

Not every customs delay is a mystery. Most hold-ups trace back to one of a handful of very identifiable causes. Understanding which one applies to your shipment helps you know whether to wait patiently or take action.

Incomplete or inconsistent documentation. The commercial invoice, packing list, and customs declaration must all match — item descriptions, quantities, declared values, and the sender’s details. Even a small mismatch between what is written on the box and what appears in the electronic manifest can trigger a manual review. This is one of the most preventable causes of delay.

Vague item descriptions. Writing “miscellaneous goods” or “personal items” on a declaration is a red flag for customs officers. Every item should have a clear, accurate description. If you are shipping supplements, electronics, or any regulated category, specificity matters even more.

Restricted or regulated items. Certain categories — food products, health supplements, batteries, certain cosmetics — attract additional scrutiny and may require prior permits or agency clearances before CBP will release them. Shipping these without the right paperwork almost guarantees a delay.

Random exam holds. CBP uses risk-based algorithms to select shipments for physical or X-ray inspection. It is not personal — it is automated. These exams can add anywhere from a few days to a couple of weeks to clearance time, and there is very little you can do to speed them up once triggered.

Seasonal and political volume surges. Certain times of year — shopping season, the lead-up to tariff changes, post-holiday rushes — push customs volumes through the roof. More parcels entering the system means slower processing for everyone. If your parcel arrived during one of these windows, congestion alone could explain the wait.

Thinking about your next shipment? Calculate your costs before you send

While your current parcel works its way through the queue, it is worth using the downtime productively — especially if you ship regularly. One of the smartest habits experienced international shippers develop is calculating the full cost of a shipment before it leaves, not after it arrives.

Why does this matter for customs? Because the declared value on your customs form directly affects how your parcel is assessed. Under-declaring to save on duties is both illegal and a very fast way to get flagged for inspection or have your goods seized. On the other hand, understanding the realistic all-in cost of your shipment — freight, insurance, and any applicable duties — helps you make smarter decisions about what to consolidate, what to ship separately, and what shipping method to use.

Consolidation is particularly worth thinking about. If you are buying from multiple Chinese sellers — whether on Taobao, 1688, or elsewhere — consolidating your items into a single well-documented shipment with one clean customs declaration is significantly less likely to cause clearance headaches than five separate small parcels arriving in different windows with inconsistent sender details.

A parcel forwarder who handles the consolidation, proper labelling, and documentation on your behalf removes most of the common declaration errors that lead to holds.

How Ebaoguo helps you avoid customs headaches before they start

The most effective way to deal with customs delays is to avoid triggering them in the first place — and that starts with getting the documentation right. Ebaoguo’s consolidation service takes care of exactly this. When your purchases arrive at our warehouse, our team consolidates them, prepares accurate commercial invoices with proper item descriptions, ensures quantities and values are consistent across all documents, and selects the most appropriate shipping line for your destination. For customers shipping to the US, UK, Australia 🇦🇺, Singapore 🇸🇬, New Zealand 🇳🇿, Hong Kong 🇭🇰, Malaysia 🇲🇾, or Taiwan 🇹🇼, this preparation step is the single biggest factor in keeping clearance times short.

Beyond documentation, our team can advise on which item categories require special handling or are best shipped via specific channels. Supplements, electronics, and certain food items all have their own rules at the US border — knowing these ahead of time prevents the kind of nasty surprises that leave parcels sitting in a warehouse for weeks. If you are purchasing from Chinese platforms and need a reliable pickup and forwarding service, or if you have items you want to store and batch together before shipping, we have you covered.
