从中国空运至美国

从中国到美国的空运是时效性货物的最快运输选择。对于电子产品制造商、跨境电商出口商和高价值货物托运人而言，从中国机场出发3-5天到达美国枢纽的速度是海运无法企及的。恒信伟业从中国所有主要机场提供空运服务，并确保锂电池及其他危险品的IATA DGR合规。请参阅我们对亚太航线空运运力趋势的报道，了解当前市场状况。

美国机场枢纽与运输时效

西海岸（主要门户）

• Los Angeles (LAX): 3–4 days from PVG/TAO. The single largest entry point for China–US air cargo. Accounts for roughly 25% of all US air cargo imports from Asia.
• San Francisco (SFO): 3–4 days. Strong for Bay Area technology sector shipments.

中西部和中部

• Chicago (ORD): 4–5 days. Major hub for Midwest distribution. Strong connectivity to manufacturing and e-commerce fulfillment centers.
• Dallas/Fort Worth (DFW): 4–5 days. Central US hub with excellent domestic trucking connections.

东海岸

• New York (JFK): 4–5 days. Primary East Coast air gateway. Serves the largest US consumer market.
• Miami (MIA): 4–5 days. Key gateway for Latin American transshipment and Florida/Southeast US distribution.

航空公司选择与运力

The China–US air freight market is served by a mix of freighter and passenger belly capacity. Our carrier relationships include access to Cathay Pacific Cargo, China Southern Cargo, Air China Cargo, Atlas Air, Polar Air Cargo, and Korean Air Cargo (via ICN transshipment). During Q4 peak season (October–December), air freight capacity tightens significantly as US holiday imports surge. We recommend booking 2–3 weeks in advance during peak season.

中美空运费率影响因素

Air freight rates on this lane are driven by several factors:

• Seasonality: Q4 rates can double compared to Q1 off-peak rates
• Weight/volume ratio: Chargeable weight = actual weight or volumetric weight (L x W x H cm / 6000), whichever is greater
• Fuel surcharge: Indexed to jet fuel prices and adjusted monthly
• Security surcharge: TSA-mandated screening fees for US-bound air cargo

危险品空运：锂电池及其他危险品

Lithium batteries and other dangerous goods must comply with IATA DGR (Dangerous Goods Regulations) for air transport. The classification depends on battery size and configuration:

• Section II (IATA DGR): Small lithium cells/batteries shipped with equipment (UN3481/UN3091, Section II). Simplified packaging and labeling requirements.
• Section IB (IATA DGR): Standalone lithium ion batteries (UN3480), up to 10 kg gross per package.
• Section IA (IATA DGR): Standalone lithium ion batteries (UN3480) exceeding Section IB limits. Full dangerous goods declaration required.

All lithium battery air shipments require: UN38.3 test summary, MSDS, and IATA-compliant packaging and labeling. See our UN3536 guide for energy storage system logistics.

电商物流：中国至美国空运

The China–US air freight lane is the backbone of cross-border e-commerce. Platforms like Shein, Temu, and AliExpress rely on consolidated air freight to move goods from Chinese fulfillment centers to US consumers. Great Hensen provides:

• Consolidated air freight: LCL by air for e-commerce shipments under 500 kg
• Express air freight: Time-definite door-to-door service for urgent e-commerce fulfillment
• Customs clearance: Section 321 (de minimis) clearance for shipments under $800, or formal entry for larger consignments

美国空运货物海关

Air cargo customs clearance is generally faster than sea freight. Key differences:

• AMS (Automated Manifest System): Air waybill data must be filed before aircraft departure
• Simplified clearance: Air shipments under $2,500 may qualify for informal entry
• TSA screening: All US-bound air cargo undergoes security screening at origin
