How Long Does Customs Clearance Take? & What To Expect

You placed the order. You are tracking it. Now the status says “clearance processing” and you have no idea if that means 2 hours or 2 weeks. You are not alone. This is one of the most common questions in international shipping, and the answer depends on just a few key factors.

Artemus Transportation Solutions has helped importers, customs brokers, and freight forwarders clear goods into the US since 1999 through our ISF (Importer Security Filing), AMS (Automated Manifest System), and AES (Automated Export System) filing platforms, and most of the timing differences below come down to how clean those filings are before the cargo arrives.

How Long Does Customs Clearance Take? 

Most shipments clear US customs within a few hours to 3 business days. Express courier packages usually clear in under 24 hours. Air cargo takes 1 to 3 days. Ocean freight takes 3 to 5 days. Shipments flagged for a physical exam can take 2 to 4 weeks, and regulatory holds from agencies like the FDA or USDA can stretch to 6 weeks. The speed depends almost entirely on documentation accuracy, paid duties, the value of goods, and whether CBP decides for a detailed inspect.

How Long Does Customs Clearance Take By Shipping Mode?

Different shipping modes move through customs at different speeds. Here is what to expect in each case:

Shipping Mode	Typical Clearance Time	Why This Range
Express couriers (FedEx, UPS, DHL)	A few hours to 24 hours	Carriers pre-file data electronically and handle brokerage in-house
Air cargo	1 to 3 business days	Entry filed on arrival, broker coordinates with airline and CBP
Ocean freight (FCL/LCL)	3 to 5 business days	The container has to be offloaded, entered, and released before pickup
Rail or truck (e.g., from Canada/Mexico)	1 to 2 business days	Pre-arrival filings move goods quickly if the paperwork is clean
Shipment flagged for exam	2 to 4 weeks	Cargo is moved to a CES for unloading and inspection
Regulatory hold (FDA, USDA, EPA, etc.)	1 to 6 weeks	Another agency must sign off before CBP releases the cargo

These ranges assume your paperwork is in order and duties are paid. If either of those is off, add 2 to 5 days minimum to whatever mode you are using.

What Factors Affect Customs Clearance Time?

The shipping mode gives you a baseline, but these are the factors that actually decide whether your cargo clears in hours or weeks.

1. Documentation Accuracy

Missing signatures, vague product descriptions, or mismatched values between the invoice and bill of lading will slow everything down. This is the single biggest cause of extra days in clearance. CBP cannot release cargo it cannot verify, and every correction round adds 24 to 48 hours.

2. HTS Classification

The Harmonized Tariff Schedule code decides the duty rate for every product you import. Wrong code means CBP holds the shipment until the classification is corrected, which can take days if your broker has to research and resubmit the right code. Getting this right up front is one of the cheapest ways to speed up clearance.

3. ISF & AMS Filings

For ocean shipments, the Importer Security Filing must be in at least 24 hours before loading at the foreign port. Late or missing ISF filings carry penalties up to $5,000 and guarantee a hold. The AMS (Automated Manifest System) filing from the carrier has a similar 24-hour rule. If either is late or mismatched, the cargo does not move.

4. Duty & Fee Payment

Duties, Merchandise Processing Fee, and Harbor Maintenance Fee all need to be paid before CBP releases the cargo. An unpaid entry is a stopped entry. Most importers handle this through their broker, but payment lags still happen, usually around holidays and month-end.

5. Shipment Type

Regulated goods like food, drugs, cosmetics, electronics, and chemicals need approval from other agencies on top of CBP. FDA, USDA, EPA, or FCC reviews add days or weeks to the normal clearance timeline, especially for new importers or first-time products.

6. Port of Entry & CBP Workload

Peak volume ports like LA/Long Beach, NY/NJ, and Savannah move slower during the holiday season, after storms, or during staffing shortages. A shipment that would clear in 2 days in January might take 5 days in November. Smaller ports and inland crossings are often faster than major gateways.

7. Value of Goods

The declared value of your shipment affects both duty calculation and CBP scrutiny. Higher-value shipments undergo more detailed review, especially for classification and valuation accuracy. Declared values that look too low for the goods are a common red flag for undervaluation, which triggers a document review that adds 5 to 10 days. Formal entries (over $2,800 as of 2025) go through a fuller process than informal entries.

8. Peak Seasons & Special Circumstances

Volume spikes cause system-wide slowdowns that affect every importer, even those with clean paperwork. The Q4 holiday rush, Chinese New Year ramp-ups, hurricane season at Gulf and East Coast ports, port worker strikes, and sudden tariff changes (like the 2025 de minimis elimination) all push clearance times 2 to 5 days longer than normal. Build buffer time into your shipping plan during these windows.

9. Customs Bond Status

Formal entries over $2,500 need an active customs bond. A lapsed bond stops the shipment at the port and can take 1 to 3 days to resolve, depending on how fast the new bond is posted and verified.

After Customs Clearance, How Long Until Delivery?

Once CBP releases your shipment, delivery usually happens within 1 to 3 business days. The exact time depends on the carrier, the distance from the port or hub to your location, and whether the cargo needs consolidation or trucking.

Here is what typical post-clearance delivery looks like in practice:

Express courier packages: Same day or next business day in most US metro areas. FedEx, UPS, and DHL move cleared packages straight into their domestic network.

Air cargo (B2B freight): 1 to 3 business days from airport to warehouse, depending on whether you use a freight forwarder or pick up yourself.

Ocean freight (FCL): 1 to 5 business days from port to final destination, plus trucking time. Rural or inland deliveries take longer than port-adjacent ones.

LCL ocean shipments: 3 to 7 business days because the cargo has to be deconsolidated at a CFS warehouse before it moves.

If your tracking says “customs clearance completed” but the package has not moved in 3 business days, the issue is usually with the carrier or a pickup scheduling problem, not customs.

Why Is My Package Stuck In Customs?

If your shipment is past the normal clearance window, it is almost always one of these five reasons:

1. Paperwork issue. Missing or inaccurate documents, mismatched values, or vague descriptions. CBP cannot release cargo that it cannot verify.

2. Unpaid duties or fees. Duties, MPF, or Harbor Maintenance Fee have not been paid yet. Usually, a 24-hour fix is once the importer or broker processes the payment.

3. Physical inspection. CBP uses risk-based targeting. Even clean shipments get flagged sometimes. Intensive exams at a Centralized Examination Station take the longest.

4. Regulatory hold. The FDA, USDA, EPA, FCC, or CPSC needs to sign off before CBP can release the cargo. This is common for food, cosmetics, electronics, and chemicals.

5. Wrong HTS code or declared value. CBP flags entries where the declared value looks too low or the classification does not match the goods. This triggers a document review that can take 5 to 10 days.

What To Do If Your Shipment Is Taking Too Long?

If your shipment has been in customs for more than 3 business days past the expected clearance window, here is the sequence that works.

Step 1: Get the CBP hold reason. Contact your customs broker or freight forwarder to inquire about the specific hold code or reason. Carrier tracking language is vague, the CBP hold code tells you exactly what is wrong.

Step 2: Check your paperwork. Pull the commercial invoice, packing list, and bill of lading. Look for mismatches in quantity, value, consignee name, or country of origin. Fix anything inconsistent.

Step 3: Confirm duties are paid. Your broker can tell you if the entry is paid in full. If not, this is a one-day fix.

Step 4: Respond to CBP requests fast. If CBP has sent a CF-28 (Request for Information) or CF-29 (Notice of Action), respond within the deadline, usually 30 days. Waiting makes the hold longer.

5 Ways To Speed Up Customs Clearance

Most delays are preventable. Here is what importers with fast, clean clearance consistently do.

1. File ISF on time, every time. Submit Importer Security Filings at least 24 hours before the vessel loads. Automate this with reliable filing software so a human error does not cost you $5,000 and a 2-week hold.

2. Get HTS classification right up front. If you are not sure of the correct code, ask your broker for a pre-classification review. A wrong code is far more expensive than the hour it takes to check it.

3. Keep documents consistent. The invoice, packing list, bill of lading, and ISF should all show the same quantity, value, description, consignee, and origin. Any discrepancy is an invitation for CBP to dig deeper.

4. Work with a licensed customs broker. A broker files entries electronically, spots errors before submission, and talks to CBP directly when something needs fixing. Solo importers without broker support almost always clear slower.

5. Build a clean compliance history. CBP uses historical data in its targeting system. Importers with a clean track record on import compliance get flagged less often than importers with past errors. Consistency pays off over time.

Conclusion

Customs clearance is rarely the bottleneck when paperwork is clean, duties are paid, and filings go in on time. Most shipments clear in a few hours to 3 days. The exceptions, exams, regulatory holds, and classification disputes almost always trace back to something fixable before the cargo even leaves the foreign port.

If your shipment is stuck right now, get the CBP hold reason from your broker, check for paperwork mismatches, and confirm duties are paid. If you are a regular importer, tighten your ISF, AMS, and entry filings and work with a licensed broker who files clean every time. That is what separates importers who spend hours explaining delays to customers from those who barely think about customs at all.
