A Guide to Customs Clearance of Air Freight

📅 July 2026 Update: Air freight importers face a high-scrutiny CBP environment. Section 301 tariffs on Chinese goods (25% on most products) apply equally to air shipments. The de minimis exemption is globally suspended — air courier and postal shipments previously entering duty-free now require formal or informal customs entry. FDA-regulated air cargo (pharmaceuticals, food, cosmetics) faces additional MoCRA and FSMA enforcement scrutiny. Accurate Air Waybill (AWB) documentation and 10-digit HTS classification are critical.

Understanding Customs Clearance for Air Freight

Customs clearance for air freight is the process by which CBP (Customs and Border Protection) verifies, classifies, and authorizes the entry of goods arriving at U.S. airports. Given the speed of air transport, clearance timelines are compressed — delays from documentation errors or exam selection have an outsized impact on time-sensitive shipments.
Air freight customs clearance is overseen by CBP and must be processed through ACE (Automated Commercial Environment). For FDA-regulated products — food, pharmaceuticals, cosmetics, medical devices — the importer must also coordinate with FDA’s PREDICT system (or, as of August 2025, the new ImportShield Program) to ensure proper prior notice and product review.

The Air Freight Customs Clearance Process

Step 1 — Pre-arrival documentation: File an Air Cargo Advance Screening (ACAS) entry if required. Prepare: Air Waybill (AWB), commercial invoice, packing list, and any regulatory permits (FDA Prior Notice for food/cosmetics, DEA permits for controlled substances, USDA APHIS permits for plants/animals).

Step 2 — Entry filing in ACE: Your customs broker files an informal entry (for shipments under $2,500) or formal consumption entry in ACE. For FDA-regulated goods, a Prior Notice must be submitted through FDA’s PNSI at least 4 hours before arrival (8 hours for international air).

Step 3 — CBP review and exam selection: CBP uses automated targeting to determine which shipments to inspect. The Automated Targeting System (ATS) scores shipments for risk — high-value, high-duty goods from certain origins face elevated exam rates in 2025–2026.

Step 4 — Payment of duties and fees: Duties calculated on HTS classification: MFN duty + applicable Section 301 tariffs (China origin) + ADD/CVD (if subject) + Merchandise Processing Fee. No Harbor Maintenance Fee for air imports.

Step 5 — Release: Once CBP releases the entry, the airline or freight forwarder delivers to the importer or designated agent.

Key Players in Air Freight Customs Clearance

  • Customs Broker: Files the entry, classifies goods (10-digit HTS), calculates duties, and communicates with CBP. For air freight, speed is critical — experienced brokers pre-classify before the aircraft lands.
  • Freight Forwarder: Arranges air transport, issues AWB, consolidates shipments, and coordinates delivery. Many forwarders have in-house customs brokerage.
  • Airlines/Ground Handlers: Hold cargo until CBP release. Demurrage and handling fees accrue if clearance is delayed.
  • CBP and FDA: CBP manages entry; FDA reviews Prior Notices for regulated products and can issue Refusal of Admission notices for non-compliant goods.

Common Challenges in Air Freight Clearance (2025–2026)

  • Incomplete documentation: Missing AWB data, invoice discrepancies, or absent permits cause immediate holds. Pre-shipment documentation review is essential.
  • Increased exam rates: CBP has significantly elevated exam selections in 2025–2026. Demurrage costs at air facilities can accumulate quickly — budget for 2–5 day potential delays.
  • Tariff complexity: Section 301 surcharges on Chinese-origin air freight, combined with the end of de minimis, have dramatically increased duty exposure for many importers. Work with a broker to verify correct classification before shipping.
  • FDA holds: Cosmetics shipped without MoCRA-compliant facility registration face immediate detention. Food shipments must have FSMA-compliant FSVP documentation on file.
  • Unexpected costs: Exam fees, storage charges, and CBP penalty exposure for misfiled entries — a licensed broker’s accuracy pays for itself many times over on high-value air shipments.
