Derivation Chain

Step 1 Rapid growth of interest in Rakuten overseas direct purchase
→
Step 2 Confusion among 50s about overseas direct purchase customs calculation
→
Step 3 Problem of ordering items that are not clearable and get disposed of without knowing

Problem

When people in their 50s order health supplements, quasi-drugs, and electronic devices from Japanese and US direct purchase malls, there is no way to check in advance whether the items are prohibited from customs clearance under Korea's Ministry of Food and Drug Safety (MFDS) and Korea Customs Service regulations. If customs clearance is rejected, disposal or return shipping costs of 30,000-50,000 KRW (approx. $22.50-$37.50) are incurred, and it takes 2-3 weeks from order to disposal notification, losing both time and money.

Solution

Entering a product name or URL automatically estimates the HS code and cross-references it with the MFDS's import-prohibited ingredients and the Korea Customs Service's restricted items database, instantly showing a three-level verdict: 'Clearable / Caution / Not Clearable.' Includes Japanese and English product name translation into Korean and ingredient label interpretation.

Target: Ages 45-60, users of Japanese and US direct purchase sites, purchasing health supplements, cosmetics, and electronic devices at least once a month.
Revenue Model: Free (10 searches per month), Premium Plan at 1,900 KRW/month (approx. $1.43) with unlimited searches, per-item duty rate integration, and favorite item alerts.
