Was the wafer customs declaration rejected? Jiangxi enterprises are secretly using this trick!

The Nanchang Bonded Area is brightly lit in the middle of the night, and boxes of wafers with anti-static labels are waiting for customs clearance. Mr. Zhang frowned as he stared at the customs declaration form on the computer screen - this was already the third time this week that the form had been rejected due to incomplete declaration elements. As the head of the supply chain of a semiconductor enterprise in Jiangxi, he is well aware that each day of delay could cause losses of millions to the production line. As the "grain" of semiconductor manufacturing, the complexity of wafer import customs declaration far exceeds that of ordinary electronic products. This article will reveal the key processes of Jiangxi enterprises in importing wafers and break those "hidden rules" in the industry that customs declaration agents will never tell you.

Unlike ordinary electronic components, special attention should be paid to wafer customs declaration:

• Sensitivity of Technical Parameters: 8-inch and 12-inch wafers are subject to different regulatory conditions, and the precision of the nano-fabrication process may trigger technical export controls
• Specialty of Packaging: The anti-shock and anti-static wafer boxes need to be declared separately, and the transportation temperature and humidity records must be completely preserved
• Trap of Tariff Differences: Although the HS codes of polished wafers and epitaxial wafers differ only in the last digit, the tax rates can vary by up to 5%

Through visits to 20 enterprises in Jiujiang, Ganzhou and other places, it was found that:

• 73% of the enterprises were inspected due to the vague description of "wafer usage" in the declaration
• When importing wafers from Japan, more than 60% of the enterprises did not correctly provide the radioactive detection certificate of the place of origin
• Enterprises in the bonded area generally do not understand that the "collective declaration after distribution" policy can save 30% of the customs clearance time

When a Nanchang customer imported a batch of 12-inch silicon wafers, they were temporarily detained by the customs because they did not indicate "whether it contains gallium arsenide". After being represented by Zhongshitong:

• The material declaration issued by the wafer factory was supplemented within 8 hours
• The UN certification documents of the wafer boxes were submitted simultaneously
• The goods were released first and the tax was paid later through the "two-step declaration" mechanism

With the commissioning of the 12-inch wafer factory in Nanchang, it is expected that:

• In 2025, the monthly import volume of wafers in Jiangxi will exceed 30,000 pieces
• The tariff preference policies for silicon carbide wafers may be adjusted
• Customs AEO certification will become a necessary qualification for rapid customs clearance

Ms. Li was just fined 50,000 yuan last week due to the improper description of the wafer surface treatment process.
