The race is on to get Chinese goods into the U.S. before President Donald Trump¡¯s tariffs bite.

At sea and in the sky, the U.S. president¡¯s trade war with China has ignited a freight frenzy. Hyundai Merchant Marine Co.¡¯s vessels leaving China for the U.S. are full, deliveries to California ports are surging, and cargo rates for journeys across the Pacific are at a four-year high.

The levies that kick in Monday have amplified the busy pre-holiday season as Chinese manufacturers rush everything from toys to bikes to car parts into American stores before tariffs hit. At Air China Ltd., freight to the U.S. is booming.
