Full Process Customs Declaration Guide for Shanghai Casual Imported Food Agency

1.Compliance Access Threshold for Casual Imported Food Agencies

The first step to act as an agent for imported casual food is to clarify access boundaries.According to General Administration of Customs Decree No.248 of 2026,all imported food must complete GACC registration for overseas manufacturing enterprises.Special categories including meat,dairy products and canned food require additional filing certificates of representative offices in China.For example,a Southeast Asian customer imported nuts,but the factory failed to complete registration and filing,leading to 12 days of port detention after cargo arrival,with storage fees of CNY 200,000 incurred.

The core compliance list covers three types of documents: ① Certificate of Origin (Form A/RCEP) -- member states such as Japan and Australia can enjoy tariff reduction and exemption; ② Health Certificate (issued by the official authority of the exporting country) -- production date,shelf life and storage conditions must be clearly marked; ③ Chinese label filing certificate -- must be completed before import,including ingredient list (specific content must be marked for ingredients such as potassium sorbate),nutrition facts table (6 mandatory indicators including energy and protein),Chinese name and producer information.

2.Key Operation Points of 2026 Customs Valuation and Commodity Inspection Pre-Review

The most common risk in the customs valuation link is "the deviation between declared price and average transaction price in the same period exceeding 10%".Zhongshitong recommends adopting the "dual-track verification method": based on the commercial invoice provided by the importer,submit 3 supporting documents at the same time -- ① Ocean bill of lading of the same batch (showing actual transaction price); ② Import data of destination country customs (must match the declared price); ③ Third-party price evaluation report (for high-value snacks such as chocolate gift boxes).

Commodity inspection pre-review should focus on 3 key information points in the "Animal and Plant Quarantine Certificate":

• The certificate issuance date must be within 15 days before the customs declaration date
• It must be clearly marked whether the "processing technology" includes "frying/baking" (which affects subsequent inspection and quarantine)
• For pre-packaged food,it is required to indicate "whether it contains allergens" (such as peanuts and nuts) in the remark column

A European customer once omitted allergen information in the certificate remarks,leading to extra sampling and re-inspection of goods during commodity inspection,delaying customs clearance by 7 days.

3.Differentiated Services of Imported Food Agencies at Shanghai Port

As an agency headquartered in Shanghai,Zhongshitong has three core capabilities:

• National port linkage: can coordinate simultaneous declaration at multiple ports including Yangshan Port,Waigaoqiao and Pudong International Airport,shortening the overall time limit by 30%
• Global agency network: has established direct connections with agents in 28 countries across Japan,South Korea,Europe,America and Southeast Asia,ensuring documents such as certificates of origin are collected within 3 working days
• Label pre-review: connects with Shanghai Customs Food Division in advance to conduct compliance pre-check on the initial draft of label design,avoiding rejection of first declaration

Taking Shanghai Port as an example,under the newly implemented "advance declaration + two-step declaration" policy in 2026,Zhongshitong has reduced the average customs clearance time from 72 hours to 48 hours through "manifest data pre-entry + bill of lading information pre-verification".

4.Risk Early Warning and Response for Casual Imported Food Agencies

Common hidden risks and solutions:

After the adjustment of the RCEP tariff policy in 2026,Zhongshitong added a "tariff calculation tool": by entering the certificate of origin and HS code,tariff reduction and exemption details can be automatically generated.A Japanese customer successfully applied for a 5% tariff preference through this tool,saving about CNY 32,000 in costs for a single batch of goods.

5.Practical Case: Full Process of Importing Casual Snacks from Southeast Asia

Scenario (S): An enterprise imports dried mangoes from Thailand,an RCEP member state,and needs to complete customs clearance before the peak season in June

Task (T): Complete label filing,certificate of origin application and commodity inspection pre-review within 3 working days

Action (A):

• Submit the GACC Overseas Enterprise Registration Certificate 7 days in advance to confirm the qualification of the Thai factory
• Launch Chinese label design simultaneously,with key marks of "dried mango (dried product)" and "shelf life 12 months"
• Coordinate with the Thai agent to issue the Form RCEP certificate to ensure compliance with the requirements of "tariff code matching + direct shipment from the country of origin"

Result (P)

: The goods arrived at the port on time,the overall customs clearance time was 2 days faster than the industry average,the tariff was reduced by 4.8%,and the cost was saved by about CNY 150,000.

Shanghai casual imported food agencies should take "compliance as the shield and efficiency as the spear" -- Zhongshitong’s 20 years of frontline experience proves that only by thoroughly handling every link including GACC registration,label filing and quarantine certificate can we truly realize the goal of "safely introducing high-quality goods from around the world".
