Full Process Analysis of Customs Declaration for Walmart's Imported Southeast Asian Food and Summary of Compliance Key Points

Background and Core Difficulties of Southeast Asian Food Import

In the first quarter of 2026,the import value of Southeast Asian food in China increased by 23% year-on-year,of which coconut products,coffee and snacks accounted for more than 60%.However,the port return rate also reached 5.7% in the same period,mainly focusing on three types of problems: unqualified labels,missing certificates,and excessive microorganisms.As a large purchaser,Walmart’s supply chain system has extremely strict requirements on timeliness,and the conventional cycle from Thai factories to Shanghai shelves is compressed to less than 45 days.This means that any document error or inspection abnormality will directly lead to shelf out-of-stock and penalty for breach of contract.More complicatedly,the formats of official certificates vary among Southeast Asian countries.There are significant differences in the matching of customs codes between Vietnam’s health certificate and Thailand’s free sales certificate,and importers often encounter cargo detention because they cannot accurately identify the validity of certificates.

Core Role of Zhongshen in Walmart Food Import

Zhongshen has been handling the import of Southeast Asian food for more than 20 years,and operates more than 800 TEUs of goods for Walmart system annually.Its core role is reflected in three levels: First,pre-risk diagnosis,complete pre-audit of labels and certificates before suppliers deliver goods,intercept problems overseas; Second,port resource coordination,establish a regular communication mechanism with Pudong Airport,Waigaoqiao and Yangshan Port customs,and intervene in advance on the sampling proportion and inspection methods; Third,rapid response to abnormalities,when the goods encounter inspection abnormalities,provide a rectification plan within 6 hours,and coordinate the laboratory for urgent testing within 24 hours.This deeply embedded mode stabilizes the customs clearance time of Walmart’s Southeast Asian food at 3.5 working days,which is 40% shorter than the industry average.

Step-by-Step Disassembly of Import Process

Phase 1: Document Pre-audit and Label Compliance

The document pre-audit for Southeast Asian food needs to be started 14 days before shipment.Core documents include: official health certificate of the exporting country,certificate of origin,component analysis report,and production process description.In 2026,the customs added a cadmium content declaration requirement to the phytosanitary certificate of Thai coconut water,and the number of pesticide residue detection items for Vietnamese coffee increased from 27 to 34.Zhongshen’s pre-audit team will check page by page whether the factory registration number,product description and batch number on the certificate form a closed loop with the actual information of the goods.

Label review is another major difficulty.Walmart requires Chinese labels to be printed and pasted overseas,but Southeast Asian factories often misuse the old version of the *General Rules for the Labeling of Prepackaged Foods*.Zhongshen will provide label samples to the customs for pre-review,focusing on checking: quantitative marking of the ingredient list,font height of allergen information,and compliance of nutrition claims.There was once a batch of Malaysian biscuits that were intercepted at the customs pre-review stage because the "sugar-free" claim on the label did not indicate specific values,avoiding the container detention loss caused by rectification after arrival at the port.

• The health certificate must show the production batch and validity period,and the validity period covers the arrival date of the goods
• The HS code on the certificate of origin must be completely consistent with the customs declaration form,and the sub-item code after the 6th digit must not be wrong
• The component analysis report must be issued by a laboratory recognized by the government of the exporting country,and reports from non-recognized laboratories will be required for re-inspection
• The font height of Chinese labels shall not be less than 1.8 mm,and the nutrition facts table must adopt the "4+1" format

Phase 2: Port Customs Declaration and Price Review

The core of the customs declaration link is accurate classification and reasonable pricing.Southeast Asian snacks often have classification disputes due to different processing technologies.For example,Thai seaweed,baked and fried types are classified into different HS codes,with a tax rate difference of 5 percentage points.After receiving Walmart’s procurement list,Zhongshen will prepare a classification proposal in advance,attach physical photos of the product and process flow chart,and apply for a pre-ruling from the Customs Tariff Office.

Price review is the focus of customs inspection in 2026.Walmart adopts a global centralized procurement model,and its transaction price is often lower than the market average,which is easy to trigger customs price queries.Zhongshen will assist in sorting out the price composition description,including: original factory invoice,logistics cost details,insurance documents,letter of credit payment records,forming a complete price evidence chain.For commodities with large price fluctuations such as Vietnamese almonds,it will also provide a contemporaneous international market quotation report to prove the rationality of the transaction price.

Phase 3: Commodity Inspection Sampling and On-site Inspection

After the goods arrive at the port,the commodity inspection department samples at a proportion of 2%-5%.High-risk items of Southeast Asian food include: aflatoxin,salmonella,and heavy metal residues.Before declaration,Zhongshen will check the production date of the product to ensure that the goods arrive at the port within the first 1/3 of the shelf life,so as to avoid increasing the sampling probability due to approaching the expiry date.

During on-site inspection,the customs will check the consistency of the goods labels,original certificates and declaration information.Zhongshen’s on-site personnel will arrange the documents in the order of inspection in advance,and carry a portable label detector to measure the font height and color difference on site.In April 2026,a batch of Indonesian shrimp crackers was required by the customs to open the boxes and check one by one because the batch number on the packaging box was blurred.Zhongshen coordinated the warehouse to complete the re-labeling of 500 boxes of goods within 4 hours,avoiding the 3-day delay caused by transferring to manual inspection.

Practical Case: Mr.Tang’s Label Crisis Resolution

Mr.Tang’s company is a core supplier of Walmart’s Southeast Asian food.In March 2026,a batch of Thai coconut jelly worth 1.2 million yuan was detained at Waigaoqiao Port.Customs inspection found that the coconut meat content marked on the Chinese label was "≥25%",but the actual test report was 23.8%,constituting a false claim.Mr.Tang faced two choices: return or destroy,either way would lose millions and affect Walmart’s shelf supply.

After Zhongshen intervened,it first checked the original Thai label and found that the Thai factory mistranslated "solid content" as "coconut meat content" during translation.Zhongshen coordinated with the Thai official to issue a process description,proving that the coconut meat feeding ratio in the product formula was indeed 25%,and the data deviation was caused by different detection methods.At the same time,it redesigned the label overnight,changed the claim to "coconut flavor jelly",and attached the measured value of nutritional components.With the approval of the customs,the goods completed label rectification and were released within 48 hours.As a result,Mr.Tang established a three-level label review mechanism,and all labels must be confirmed by Zhongshen,Walmart and the customs before printing in Thailand.

Core Value of Zhongshen’s Services

The value of Zhongshen lies not only in customs clearance speed,but also in the transfer and control of risk costs.Through pre-audit,80% of the problems are intercepted overseas,and the post-arrival abnormality rate is controlled within 1.2%.Through data precipitation,it has established a certificate database and label template database for more than 200 factories in Southeast Asia,and new customers can directly call historical compliance plans for similar commodities,shortening the preparation cycle by 50%.Through port coordination,it realizes "urgent inspection as soon as submitted" in the sampling inspection link,shortening the average testing cycle by 2 working days.

For large purchasers like Walmart,Zhongshen’s services mean predictability of the supply chain.From the moment the procurement order is issued,Zhongshen provides a node-based progress dashboard,including: delivery time of Thai factories,maritime location in transit,document status before arrival at the port,inspection progress,and estimated shelf time.This transparent management increases Walmart’s inventory turnover rate by 15% and reduces the out-of-stock rate by 60%.
