Delays are still being reported at transit hubs and importers continue to rush shipments in advance of unfilled quotas, Trans Global Logistics said in an email note.

Fuel surcharges and freight rates remain high as stabilizing oil prices and moderating shipping demand have been offset by the weak U.S. dollar. Today, OPEC announced a $1 per barrel increase for oil.

Activity remains strong at Taipei and Shanghai, where new customs clearance procedures went into effect Dec. 1 and products to be shipped are reportedly delayed up to three days.

China is expected to see a bump in activity in the next four weeks, leading up to the Chinese New Year on Feb. 9. "We expect markets in China to be very active in early January as importers rush to take advantage of quota elimination on many apparel categories. Export activity will also spike in early February because Chinese factories will shut down during the weeklong Lunar New Year holiday," Trans Global wrote.
