About Sealution
Business Overview
A rare, hands-on expert spanning all three domains — global logistics + cross-border e-commerce + tax and finance.
Four Core Strengths
01 Full-Chain Integration of Customs · FX · Tax
Customs declaration, FX collection, tax rebate and bookkeeping are delivered as a closed loop within a single entity, covering all models: 9810 / 9610 / 9710 / 1039 / 0110. This one-stop full-chain service eliminates patchwork across multiple agencies, fragmented information and gaps in accountability.
02 Group Logistics and Overseas Warehouse Infrastructure
Backed by the 15-year cross-border logistics infrastructure of AWESUNG Group, logistics data converts directly into customs data, so a single set of documents completes both customs declaration and export tax rebate filing. The four flows — goods, capital, documents and business — are integrated, and tax rebates are never held up.

Our founder is the former CFO of a leading cross-border seller with sales of RMB 10 billion, and previously served as a senior finance executive at Midea Group and a senior finance expert at Alibaba.
