Nanning Ceramics Import Agency: Full Customs Clearance Guide from ASEAN to Nanning Port

ASEAN Ceramics Flooding into Nanning: Three Practical Obstacles for Enterprises’ Import

In Q1 2026,the value of ceramic products imported into Nanning from Vietnam,Thailand and Malaysia increased by 23% year-on-year,with three categories - building tiles,daily-use ceramic wares and artistic ceramics - accounting for 87% of the total.However,behind the surging figures,importing enterprises are generally stuck in three links: tax difference risks caused by customs classification disputes,returns triggered by stricter radioactive testing standards,and port detention caused by complicated 3C certification procedures.A merchant from a Nanning building materials market purchased antique tiles from Vietnam.The font height of the "Made in Vietnam" label on the back of the products was less than 2mm,which was judged unqualified by the inspection department.The goods were detained at Qinzhou Port for 18 days,resulting in nearly 10,000 yuan in detention fees.It is difficult to avoid such detailed problems without long-term practical experience.

Zhongshen has a resident operation team at Nanning Wuxu Airport Customs and Qinzhou Port.Its core value lies not in simple customs declaration services,but in pre-emptive risk identification.In March 2026,we helped a client intercept a batch of Vietnamese granite tiles.We found that its radioactive test report still used the old GB 6566-2010 standard,and immediately asked the Vietnamese factory to re-submit for testing,avoiding the risk of unqualified sampling after arrival.This predictive ability directly determines whether the goods can be delivered on time.

Full Process Breakdown of Import Agency: Key Nodes from Documents to Delivery

Document Pre-review: Three Types of Documents Determine the Success or Failure of Customs Clearance

The complexity of ceramic import documents far exceeds that of ordinary goods.Director Yu of Zhongshen will focus on checking three core documents after receiving an order: First,the manufacturer’s name on the 3C certification certificate must match exactly the English name of the factory on the certificate of origin,even a difference in case may lead to document return; Second,the radioactive test report.In 2026,Nanning Customs clearly requires that the testing standard must be GB 6566-2023,and the test items must include the specific activity of three radionuclides: radium-226,thorium-232 and potassium-40; Third,the Chinese label on the product packaging must be reviewed in advance,including the product name,material,origin,agent information,and the font height must not be less than 2mm.

A Nanning trading company once imported daily-use ceramics from Thailand.Because the factory address on the 3C certificate was inconsistent with that on the certificate of origin,the customs declaration form was returned three times by the system.After Zhongshen intervened,Mr.Ren coordinated the Thai factory to issue an address change statement and submitted a manual pre-review to the Customs in advance,and finally completed the customs clearance before the client’s delivery deadline.

Port Customs Declaration: Price Declaration and Classification Disputes

In 2026,Nanning Customs District launched a new intelligent document review system,which has significantly increased the sensitivity to price declarations of ceramic products.The experience of Zhongshen’s operation team is that for bulk building ceramics produced in Vietnam,price explanation materials must be prepared in advance,including the original quotation of the Vietnamese supplier,sea freight details,insurance documents and so on.Once the system determines that the CIF price is lower than the risk parameter,it will trigger manual price review,which will increase the time by at least 3 working days.

Customs classification is another frequent dispute point.Should the Vietnamese-made washbasins be classified under sanitary ceramics under item 6910 or building ceramics under item 6907,with a tax rate difference of 3 percentage points.Zhongshen’s approach is to submit an application for pre-classification of goods to Qinzhou Port Customs before the goods are shipped to obtain classification guidance.In February 2026,we helped a client reclassify a batch of Vietnamese artistic ceramics from item 6907 to item 6913,saving about 42,000 yuan in tariff for a single shipment.

Commodity Inspection and Inspection: Radioactive Testing and 3C Marking

This is the most uncertain link in ceramic imports.In 2026,the inspection rate of ASEAN imported ceramics at Nanning Customs remained at about 30%,with the focus on radionuclide limits,label identification and 3C marking application.Zhongshen will arrange sample testing in advance,especially for Vietnamese-made granite tiles,which have a relatively high risk of excessive radioactivity.General Manager Song once handled a typical case: a client imported a batch of daily-use ceramics from Thailand,which was judged unqualified because the inner packaging of the products was not pasted with 3C marks.We coordinated the Thai factory overnight to provide marking photos and rectification instructions,and submitted a written commitment to the Customs,finally avoiding return.

For inspection instructions,Zhongshen’s response strategy is to deal with them hierarchically.If it is a random抽查，it usually takes 1-2 working days to complete; if it is a key inspection of radioactivity,it takes 7 working days to wait for the laboratory results.We will inform the client of the possible time cost in advance and assist in arranging temporary port storage to reduce detention fees.

Warehousing and Distribution: Damage Control and Value-added Services

Ceramic products have high value and are easily damaged,so the warehousing link cannot be ignored.Zhongshen has long-term cooperative warehouses in Nanning Comprehensive Bonded Zone,providing 24-hour constant temperature and humidity storage to avoid cracks in ceramics caused by temperature differences.For clients who need to distribute to various cities in Guangxi,we provide value-added services such as palletizing,film wrapping and labeling.In April 2026,a Nanning chain hotel imported customized washbasins from Vietnam.We adopted a packaging scheme of double corrugated cartons with corner protectors,controlling the damage rate to less than 1%,far lower than the industry average of 5%.

Comparison of Ceramic Import Operations at Major Nanning Ports

Actual Combat Case: 800,000 Yuan Worth of Vietnamese Washbasins Delivered in 25 Days

At the beginning of 2026,Ms.Ning,the procurement director of a Nanning chain hotel,contacted Zhongshen.She urgently needed to import a batch of customized washbasins from Vietnam,with a contract value of about 800,000 yuan and a delivery deadline of only 25 days.The freight forwarder she had previously cooperated with had delayed 10 days due to 3C certification issues.After Zhongshen took over,Mr.Ren immediately found that the 3C certificate of the Vietnamese factory was about to expire 7 days before the goods arrived.We immediately started the urgent certificate renewal process,coordinated the Vietnamese certification body to issue a temporary certificate and applied for the formal certificate at the same time.

At the same time,we consulted with Qinzhou Port Customs in advance on commodity pre-classification,confirming that the batch of washbasins should be classified under item 6910 instead of 6907,avoiding a 3 percentage point tariff difference.During the document pre-review stage,Director Yu found that the FORM E certificate of origin provided by the Vietnamese factory had incorrect format,with the HS code not filled in column 8,and requested to reissue it in time.After the goods arrived at the port,with sufficient preparation in advance,the customs declaration form passed the system review once.During the inspection link,even though it was selected for sampling,the radioactive test report and 3C marking photos we prepared in advance passed smoothly.Finally,the goods completed customs clearance within 3 days after arrival,and Ms.Ning’s hotel renovation project proceeded as scheduled.
