How long does customs clearance take?

For standard commercial shipments with correct documentation: 1–3 business days for air freight, 3–5 for ocean FCL, 5–10 for ocean LCL. If customs selects your cargo for a physical exam, add 2–7 days. Incomplete documents are the most common cause of delays beyond these ranges.

Do I need a customs broker?

Not legally required in most countries — you can self-file as the importer of record. However, most importers use a licensed broker because customs regulations are complex, errors are costly, and brokers have established relationships with customs authorities that speed up processing.

What triggers a customs examination?

Customs uses risk-scoring algorithms. Common triggers: new importer with no track record, high-risk commodity, country of origin with known compliance issues, mismatched invoice values, previous violations on your bond, and random selection. You cannot prevent random exams.

Who pays customs duties — the buyer or the seller?

The importer of record pays duties — that is whoever is named as the consignee on the entry filing. Under most Incoterms (FOB, CIF, CFR), this is the buyer. Under DDP (Delivered Duty Paid), the seller pays. Under EXW, the buyer also pays but arranges everything themselves.

What happens if my cargo fails examination?

If customs finds discrepancies, you have three options: re-export the goods, destroy them under customs supervision, or resolve the issue (pay additional duties, provide missing documents, amend the entry). Seizure is reserved for contraband or serious fraud.

What is a customs bond and do I need one?

A customs bond is a financial guarantee that you will pay all duties, taxes, and penalties owed. Required for all commercial imports into the United States. You can get a single-entry bond (per shipment) or a continuous bond (covers all shipments for 12 months — cheaper if you import regularly).

Can I clear customs myself without a broker?

Yes — it is called a formal entry self-filing in the US. You need an importer of record number, an ACE portal account, and knowledge of HTS codes and entry procedures. Most small importers find the learning curve steep and the risk of errors (fines, delays) outweighs the broker fee.

Does customs clearance happen at origin or destination?

Import customs clearance happens at the destination country. Export customs clearance happens at the origin country. Both are required for international shipments. Export clearance is usually simpler and handled by the shipper or freight forwarder. Import clearance requires the importer of record in the destination country.

The Process

From Port Arrival to Cargo Release

Every international shipment goes through these stages. The timeline varies by mode, destination, and whether customs selects your cargo for examination.

Vessel or Flight Arrives

The carrier submits an arrival manifest to customs. For ocean freight, this happens when the vessel berths. For air, upon landing. You cannot begin clearance until the cargo is physically in the country.

Arrival Notice Issued

The shipping line or airline notifies your freight forwarder or broker that cargo has arrived. The notice includes the container number, vessel name, and port of discharge. Act on this immediately — free time starts here.

Entry Filing

Your customs broker files the import entry with the customs authority. In the US this is the Entry Summary (CBP Form 7501). In the EU it is the Single Administrative Document (SAD). Documents submitted: commercial invoice, packing list, bill of lading, certificate of origin.

Customs Review

Customs authorities review the entry. Most shipments are released within hours. Some are flagged for a document review (desk exam) or a physical examination of the cargo. Physical exams can add 2–7 days to the timeline.

Duty and Tax Assessment

Customs calculates the applicable duties, VAT, and other taxes based on the HS code, declared value, and country of origin. The importer of record is responsible for payment.

Duty Payment

You or your broker pays the assessed duties and taxes. In the US, this can be done via ACH or a customs bond. In the EU, duties are typically paid via the importer's duty deferment account.

Customs Release

Customs issues a release notification. The cargo is legally cleared and can now move from the port or airport. Your broker will send you the release confirmation.

Cargo Pickup and Delivery

You or your freight forwarder arranges pickup from the terminal or CFS (for LCL). A delivery order from the shipping line is required to pick up the container. The cargo then moves to its final destination.

Documentation

Documents Required for Customs Clearance

Missing or incorrect documents are the leading cause of clearance delays. Have all of these ready before your shipment arrives.

Bill of Lading / Airway Bill

Always required

The transport contract between shipper and carrier. Required to take possession of the cargo. Must match the commercial invoice exactly — consignee name, port of discharge, container number.

Commercial Invoice

Always required

States the value, description, and terms of sale of the goods. Customs uses this to calculate duties. Must include: seller and buyer details, HS codes, unit prices, total value, Incoterm, and country of origin.

Packing List

Always required

Details the contents of each package: quantity, weight, dimensions, and marks. Customs uses it to verify the physical cargo against the invoice. Discrepancies trigger examinations.

Certificate of Origin

FTA shipments

Proves where the goods were manufactured. Required to claim preferential duty rates under free trade agreements. Without it, you pay the standard MFN rate.

Import License

Regulated goods

Required for regulated goods: food, pharmaceuticals, chemicals, weapons, certain textiles. The license must be obtained before the shipment arrives — not after.

ISF (10+2) Filing

US ocean imports

Required for all ocean FCL and LCL shipments into the United States. Must be filed at least 24 hours before cargo is loaded at the origin port. Late or missing ISF filings result in fines of up to $5,000 per violation.

Common Mistakes

6 Things That Delay Clearance

Wrong or missing HS code

The HS code determines the duty rate. An incorrect code triggers a desk review or physical exam. Always verify the code before filing — reclassification after arrival is expensive and slow.

Invoice value doesn't match reality

Undervaluing goods to reduce duties is customs fraud. Overvaluing is also flagged. Customs cross-references invoice values against market data. Discrepancies freeze your shipment.

Missing ISF filing (US imports)

ISF must be filed 24 hours before loading, not 24 hours before arrival. Many importers confuse the two. A late ISF results in a $5,000 fine and holds on future shipments.

Country of origin not documented

If you can't prove origin, you can't claim FTA rates. Even if the CO is not required, not having it means paying full MFN duties. Get the certificate from your supplier before shipment.

Consignee details don't match

The name and address on the bill of lading, commercial invoice, and packing list must be identical. Even minor differences (Inc. vs Incorporated) can trigger a hold and require a correction filing.

Not appointing a customs broker early enough

Brokers need documents before the shipment arrives, not after. Waiting until the vessel docks means scrambling to file entry while free time ticks away. Brief your broker when you book the shipment.
