What Is Customs Clearance?

Customs clearance is the process of getting approval from U.S. Customs and Border Protection (CBP) to bring imported goods into the country. This involves submitting required documentation, paying duties and taxes, and complying with regulations from various government agencies.

Step-by-Step US Customs Clearance Process

Step 1: Obtain an Importer Number

Before importing, you need an Importer of Record (IOR) number. This is typically your:

• EIN (Employer Identification Number) - For businesses
• SSN (Social Security Number) - For individuals
• CBP Assigned Number - For foreign importers

Apply through CBP →

Step 2: Determine HS Code Classification

Every product has a specific Harmonized System (HS) Code that determines:

• Duty rates
• Import restrictions
• Required certifications

Example HS Codes:

Step 3: File Entry with CBP

Your customs broker or freight forwarder will file CBP Form 3461 (Entry/Immediate Delivery) to initiate the clearance process. This must be done:

• Before arrival: For ocean freight, file at least 24 hours before loading
• Upon arrival: For air freight, file within 15 days of arrival

Step 4: Submit Required Documentation

Key documents required for customs clearance:

1. Commercial Invoice - Shows value of goods
2. Bill of Lading (BOL) - Contract between shipper and carrier
3. Packing List - Details of contents and packaging
4. Arrival Notice - Sent by carrier when goods arrive
5. Certificate of Origin - If claiming preferential duty rates

Step 5: Pay Duties and Taxes

Import duties must be paid before goods are released. Payment methods:

• ACH (Automated Clearing House) - Most common
• Check or Money Order - Slower processing
• Credit Card - For smaller shipments

Additional taxes may include:

• Merchandise Processing Fee (MPF) - 0.3464% of value (min $31.67, max $614.35)
• Harbor Maintenance Fee (HMF) - 0.125% of value (ocean freight only)

Step 6: CBP Examination (If Selected)

Approximately 2-5% of shipments are selected for examination:

Step 7: Other Government Agency (OGA) Review

Certain products require additional approval:

• FDA (Food and Drug Administration) - Food, drugs, medical devices, cosmetics
• FCC (Federal Communications Commission) - Electronics that emit radio frequency
• USDA (Department of Agriculture) - Plants, animals, agricultural products
• EPA (Environmental Protection Agency) - Chemicals, pesticides, vehicles

Step 8: Cargo Release

Once CBP approves your entry and all requirements are met, they issue a Cargo Release. Your goods can then be picked up and delivered to your warehouse.

Common Customs Clearance Mistakes to Avoid

1. Incorrect HS Code Classification

Impact: Wrong duty rates, penalties, delays

Solution: Work with experienced customs broker or use CBP's HTS Search Tool

2. Undervaluation of Goods

Impact: CBP audits, penalties up to 4x duty owed, criminal charges

Solution: Declare actual transaction value including:

• Product cost
• Tooling and molds
• Assists (materials provided by buyer)
• Royalties and license fees

3. Missing or Incomplete Documentation

Impact: 3-7 day delays, storage fees

Solution: Use document checklist and verify all information before submission

4. Ignoring Anti-Dumping/Countervailing Duties (AD/CVD)

Impact: Unexpected duties of 100-500%+

Solution: Check if your products are subject to AD/CVD orders

5. No Continuous Customs Bond

Impact: Higher costs for frequent importers

Solution: Purchase annual bond ($50,000 coverage for ~$500-800/year)
