Previously, Sung Moo Kim CHB used another software vendor before using Customs City. “We wanted to lower our costs and streamline the process to grow the business,” said Mr. Kim, President at Sung Moo Kim CHB. Our previous software vendor submission process of ACE Air and Type 86 was time-consuming as the process included some manual tasks. “We had to manually check all the HTS codes, find the invalid ones and then manually replace them, which was not efficient for our team,” said Mr. Kim. Our team had to wake up very early or stay up late due to some system limitations around the timing of sending HAWB data to CBP.

Sung Moo Kim CHB needed a solution that is robust, reliable, cost-effective, quick to process high volume shipments, and easy to use.


To help streamline the process, Customs City offered an all-in-one solution comprising both Type 86 and ACE Air, which enables Sung Moo Kim CHB to easily upload & submit more than 50K shipments at once using one file and validate the data including the HTS codes before submitting them to Customs. All required information is also accessible 24/7 via the web using the visual dashboard, enabling them to closely monitor every aspect of the customs process.

“Customs City’s system has many great tools & features; “Review HTS Codes” is our favorite as it allows us to quickly validate the HTS codes and mass replace the invalid ones,” said Mr. Kim. “Review HTS Codes” and other features such as the ability to instantly flag errors across rows of data, and the ability to upload a high volume of shipments quickly is a massive time saver for Sung Moo Kim CHB.

“Using Customs City improved our efficiency, significantly lowered the costs and streamlined the customs compliance process for our team.”
