Full Process of 2026 Imported Mouthwash Customs Clearance, Detailed Explanation of Professional Agent Practical Steps

Imported Mouthwash Customs Clearance: A Key Link in the 2026 Foreign Trade Chain

In 2026,the size of China’s domestic mouthwash market exceeded 12 billion yuan,and the market share of imported products increased by 12% year-on-year due to differentiated advantages such as natural ingredients and children-specific formulas.However,many importers report that customs clearance is often delayed by 1-2 weeks due to incomplete qualifications,inconsistent documents,updated inspection standards and other issues,and even faces the risk of cargo return.Mr.Gao is the head of a beauty trading company based in Shanghai.Last year,when importing a batch of European children’s mouthwash,he incorrectly classified "oral care liquid" as "cosmetics".Not only did he pay 3% more tariffs,but he was also required to supplement an ingredient test report,which delayed the back-to-school season sales window.This made him realize that imported mouthwash customs clearance is never just "submitting documents and going through the process",the value of a professional agency lies in avoiding hidden risks in advance.

Zhongshen has been deeply engaged in foreign trade agency for more than 20 years,focusing on full-process service for imported mouthwash customs clearance.Combining the latest 2026 customs policies,we systematically sort out core links,helping customers control customs clearance time within 3-5 days and reduce costs by more than 15%.

1.Pre-Preparation Stage: "Double Verification" of Qualifications and Documents

1.1 Stage Goal: Confirm compliant import qualifications and sort out full set of documents

Imported mouthwash belongs to "oral care products",which needs to meet multiple compliance requirements such as food contact material standards and hygiene indicators.Pre-preparation is the core to avoid subsequent problems.The goal of this stage is to complete verification of importer qualification,brand authorization,product test report,and sort out basic documents including packing list,invoice and trade contract.

1.2 Key Actions and Common Problems

• Qualification Verification: It is necessary to confirm whether the importer holds a Food Business License (with "oral care products" included in the business scope) and qualified customs declaration & inspection qualification; the brand owner needs to provide a Chinese trademark registration certificate or official authorization letter.Common problem: Some small trading companies incorrectly use "daily necessities" qualification for mouthwash import,resulting in declaration rejection.
• Document Sorting: Required documents include packing list,commercial invoice,trade contract,bill of lading,country of origin hygiene certificate,and ingredient test report (must comply with 2026 national standard GB8372-2025).Common problem: The ingredient report does not mark new 2026 requirements such as "no alcohol,no excessive fluoride",so it is required by commodity inspection to be retested.

1.3 Core Role of Zhongshen

Manager Jiang,head of Zhongshen’s customs clearance department,once assisted a start-up cross-border e-commerce enterprise to complete qualification supplementation for imported mouthwash.The customer initially only provided "daily necessities import qualification",Manager Jiang immediately pointed out the need to supplement the Food Business License,and coordinated with cooperative institutions to assist in the process.The qualification upgrade was completed in only 3 days,avoiding the risk of cargo return after arrival.In addition,Zhongshen provides the latest 2026 document templates,helping customers check the compliance of ingredient reports with national standards in advance,reducing document modification times by 80%.

2.Pre-Arrival Declaration Stage: "Accurate Control" of Commodity Code and Tariff

2.1 Stage Goal: Complete electronic declaration and tariff estimation,lock in customs clearance time

Electronic declaration must be completed 72 hours before cargo arrival.The core of this stage is commodity classification and tariff estimation,which directly affects customs clearance cost and efficiency.

2.2 Key Actions and Common Problems

• Commodity Code Classification: In 2026,China Customs updated the commodity codes for oral care products.Fluoridated mouthwash,non-fluoride mouthwash,children-specific and adult-specific products have different codes.Common problem: Classifying "children’s non-fluoride mouthwash" as ordinary oral care products increases the tariff from 6% to 10%,resulting in nearly 20,000 RMB extra payment for a single batch of cargo.
• Tariff Estimation: Tariff,value-added tax and consumption tax are calculated based on commodity code,origin (RCEP member countries can enjoy preferential tax rates) and customs value.Common problem: Low declared customs value triggers customs authenticity verification,which extends the valuation cycle.

2.3 Core Role of Zhongshen

Mr.Miao is a commodity classification consultant at Zhongshen,with 15 years of experience in customs code review.In March 2026,a client imported a batch of Japanese zinc-containing mouthwash,which was initially incorrectly classified as "cosmetics" (code 3304990090).According to the 2026 tariff adjustment,Mr.Miao reclassified it as "oral care preparation" (code 3004909090),reducing the tariff from 10% to 6%,saving 32,000 RMB in tariff for a single batch.In addition,Zhongshen provides a tariff estimation form to help clients lock in costs in advance and avoid subsequent tax replenishment.

3.Inspection,Quarantine & Examination Stage: "Key to Balance" Compliance and Efficiency

3.1 Stage Goal: Pass commodity inspection and customs examination,avoid delay

Imported mouthwash needs to undergo both customs examination and commodity inspection hygiene testing,which is the most delay-prone link in the entire clearance process.In 2026,commodity inspection added a "total microbial colony limit" test,with stricter requirements.

3.2 Key Actions and Common Problems

• Hygiene Testing: Samples are required for total colony,pathogenic bacteria and heavy metal testing.In 2026,the testing cycle is shortened from 7 days to 3 days,but advance reservation is required.Common problem: Failure to prepare samples in advance leads to testing queuing,causing delays of more than 5 days.
• On-site Examination: Customs needs to verify that the cargo name,quantity and label match the documents.In 2026,"Chinese label compliance verification" is added,which requires warning statements such as "not suitable for children under 3 years old" to be marked.Common problem: The Chinese label does not include required warning statements,so on-site rectification is required.

3.3 Core Role of Zhongshen

Mr.Qin is an examination coordination specialist at Zhongshen,and once assisted a client handle an urgent order: after a batch of German imported mouthwash arrived at the port,commodity inspection found that the label did not mark "0% alcohol content".Mr.Qin immediately coordinated a printing factory to produce compliant labels urgently,and applied for "release first,rectify later" at the same time.The label replacement was completed in only 1 day,avoiding container detention fees of 1200 RMB per day caused by cargo detention at the port.In addition,Zhongshen can book commodity inspection testing 3 days in advance,ensuring seamless connection between testing and examination,shortening the average time of this stage from 5 days to 2 days.

4.Release and Follow-up Stage: "Seamless Connection" of Pickup and Archiving

4.1 Stage Goal: Complete tariff payment and pickup,archive full set of documents

This stage requires completion of tariff payment,customs release,cargo pickup and document archiving,which is the final link of customs clearance and requires smooth logistics connection.

4.2 Key Actions and Common Problems

• Tariff Payment: Payment can be made via electronic payment,guarantee letter and other methods.2026 supports third-party payment platforms,but account permissions need to be confirmed in advance.Common problem: Insufficient account balance leads to delayed payment,causing 1-day release delay.
• Pickup and Archiving: It is necessary to check the delivery order against the cargo,and archive documents such as hygiene certificate and customs declaration,which should be kept for 2 years.Common problem: Failure to archive documents in time leads to problems in subsequent verification.

4.3 Core Role of Zhongshen

Manager Jiang is the logistics connection supervisor at Zhongshen,in charge of warehousing and distribution of imported cargo at Shanghai Port.After a client’s imported mouthwash arrived at the port,due to insufficient temporary storage capacity of the client’s domestic warehouse,Manager Jiang immediately arranged 3 days of temporary storage at a bonded warehouse under Zhongshen,and arranged delivery to the client’s warehouse the next day,avoiding cargo detention at the port.In addition,Zhongshen provides tariff agency payment service,supports multi-account payment,ensures immediate payment arrival,and release time is 1 day faster than self-declaration.
