# Full Process Analysis and Compliance Key Points of Southeast Asian Snack Food Import Agency for Nantong Enterprises

## Current Situation and Core Difficulties of Nantong’s Imported Snack Food Market

In 2026,the year-on-year growth rate of imported food consumption scale in Nantong region remains above 15%,among which Southeast Asian tropical snacks and European baked products account for nearly 60% of the market share.From Thai dried mangoes,Vietnamese coconut chips to Italian handmade biscuits,although such products have strong market demand,there are multiple risks hidden in the import link.Customs has continuously strengthened the quarantine of animal and plant-derived food.After the implementation of the new version of the Measures for the Administration of Import and Export Food Safety in 2026,label compliance review has become stricter,and the contradiction between shelf life management and seasonal sales windows has become increasingly prominent.Most Nantong enterprises lack professional teams,so they often encounter port detention and return in links such as document preparation,commodity inspection sampling,and additive verification.The average customs clearance cycle is 8 to 12 days longer than expected,and the direct loss rate reaches 3% to 5% of the cargo value.

## Practical Role of Zhongshen in the Import Agency Chain

Zhongshen has been engaged in imported food agency at Shanghai Port for more than 20 years,and is familiar with the demand characteristics of Nantong enterprises.We do not simply provide customs declaration services,but provide full-chain embedded services from front-end product access assessment to back-end warehousing and distribution.Our core role is to translate customs regulations and quarantine standards into operable paths,identify risk points in advance,and integrate the originally scattered inspection,customs declaration and transportation links into an integrated solution.Specifically,we will intervene at the stage of foreign business negotiation to review whether the product formula meets Chinese standards; coordinate the format of official certificates before shipment; and directly communicate with the laboratory on the testing plan after the cargo arrives at the port.This deep participation mode enables Nantong customers to achieve the same compliance level without building their own customs affairs team.

## Phase-by-phase Disassembly of Import Process and Risk Response

### Phase 1: Document Pre-review and Compliance Access

This phase determines whether the goods can enter the declaration process smoothly,and needs to be completed before shipment.The core work includes:

- Product ingredient review: Check whether sweeteners,preservatives and pigments are within the allowable range one by one against GB 2760 National Food Safety Standard for the Use of Food Additives.In 2026,customs will focus on monitoring the problem of excessive synthetic pigments,and some Southeast Asian snacks have been returned in full batches because they use additives allowed locally but prohibited in China.
- Label pre-review: Check whether the Chinese label completely marks the ingredient list,allergen prompt,production date,shelf life and storage conditions according to GB 7718 National General Standard for the Labeling of Prepackaged Foods.Nantong enterprises often ignore the nut allergen declaration for coconut products,resulting in rectification delays.
- Official certificate confirmation: Animal and plant-derived products must provide quarantine certificates issued by the official of the exporting country,and the format must meet the latest template requirements of the General Administration of Customs in 2026.Zhongshen will confirm the certificate title and signature elements with the official departments of Thailand and Vietnam in advance to avoid failure in customs clearance due to format non-conformity after the goods arrive at the port.
- Consistency of trade documents: The information on invoices,packing lists and bills of lading must be completely consistent,especially the product name description must be accurate to the specific product category,and cannot be written as "mixed snacks" in general.

Zhongshen provides a standardized pre-review checklist at this stage.After the customer submits the ingredient list,original label and foreign language certificate,we will issue written modification opinions within 3 working days,and assist in communicating with foreign merchants to adjust the formula or packaging.

### Phase 2: Port Customs Declaration and Accurate Tax Calculation

After the goods arrive at the port,they enter the substantive declaration stage,and the core of this stage is accuracy and timeliness.

- Customs code classification: Snack foods involve multiple HS codes.For example,dried mangoes are classified under 0813.50,and coconut chips are classified under 0801.11,with significant tax rate differences.Wrong classification will lead to tax repayment and even administrative penalties.Based on 20 years of data accumulation,Zhongshen has established a product classification database to ensure one-time accuracy.
- Dutiable value verification: Customs strictly reviews related party transactions and royalty fees.In 2026,a Nantong enterprise was levied back taxes and fined for failing to declare brand licensing fees.We will assist customers to sort out the payment chain before declaration and prepare complete pricing explanation materials.
- Tax rate applicability judgment: Under the RCEP agreement,products from Thailand and Vietnam can enjoy zero tariff,but a China-Thailand certificate of origin conforming to the rules of origin is required.Zhongshen will calculate the difference between the RCEP tax rate and the most-favored-nation tax rate,and only recommend customers to apply when the preferential margin exceeds the certificate handling cost.

We will complete the tax simulation calculation before the goods arrive at the port,and provide customers with a comprehensive cost table including customs duty,value-added tax,consumption tax and port charges,so as to avoid affecting the pick-up of goods due to tax disputes after arrival.

### Phase 3: Commodity Inspection Sampling and Laboratory Testing

This is the most critical and uncontrollable link in the import of snack foods,which directly determines the fate of the goods.

- Key points of on-site inspection: Customs officers check the integrity of packaging,label consistency and sensory properties of products.In 2026,the problem of false production dates will be severely cracked down,and Zhongshen will remind customers to retain foreign manufacturers’ production records for verification.
- Sampling and inspection rules: Microorganisms,heavy metals and pesticide residues are mandatory inspection items for animal and plant-derived foods.The sampling base is determined according to the total amount of goods,usually 6 to 12 boxes per container.Zhongshen will supervise the sampling process on site to ensure the representativeness of samples and avoid re-inspection caused by irregular operation.
- Testing cycle and results: Routine laboratory testing takes 7 to 10 working days,which may be extended during peak periods.Zhongshen has established data connection with a number of designated laboratories,and can query the testing progress in real time.If the test is unqualified,we will obtain detailed data within 24 hours to analyze whether it is a single item excess or a systematic problem.
- Disposal of unqualified products: Re-inspection can be applied for if microorganisms exceed the standard,and products with unqualified additives can only be returned or destroyed.Zhongshen will formulate targeted rectification plans according to the excessive items.In March 2026,we assisted a Nantong customer to apply for re-inspection for a batch of coconut chips with slightly excessive total bacterial count,and submitted an explanation on packaging sealing improvement at the same time,which was finally released.

### Phase 4: Warehousing Management and Distribution Connection

Customs clearance is not the end,and subsequent warehousing and distribution also affect the time to market of products.

- Temperature and humidity control: Chocolate and jelly products need constant temperature warehouses (18 to 22 degrees Celsius),and nut products need low humidity environment.Zhongshen provides classified warehousing in Shanghai to avoid deterioration caused by customers mixing different temperature-sensitive products.
- Shelf life management: We implement a first-in first-out system,and give early warning for products with a shelf life of less than 9 months to remind customers to speed up the sales pace.
- Batch customs clearance and distribution: According to the sales cycle characteristics of Nantong customers,we can adopt bonded warehouse temporary storage,and carry out batch customs clearance and distribution to Nantong warehouses to reduce one-time capital occupation.

## Actual Case: Mr.Chen’s Thai Snack Food Import Project

Mr.Chen from a Nantong trading company imported 20 containers of mixed snack foods from Thailand for the first time in early 2026,including dried mangoes,coconut chips and seaweed rolls.When negotiating with foreign merchants on his own in the early stage,he did not notice that the seaweed rolls contained a sweetener prohibited in China.Zhongshen found this problem during the document pre-review stage,and suggested replacing the formula of the product,avoiding the risk of full batch destruction after the goods arrived at the port.At the same time,for animal and plant products such as dried mangoes,we coordinated with Thai officials in advance to issue a quarantine certificate format that meets the requirements of Chinese customs,and ensured that the certificate was delivered 3 days before the goods arrived at the port.

After the goods arrived at Yangshan Port,the customs sampled and tested the microbial indicators,and there was a slight excess due to the problem of packaging sealing.With experience,Zhongshen applied for re-inspection within 2 hours after learning the initial test result,and submitted a rectification explanation at the same time,promising to improve the packaging process for subsequent batches.The re-inspection result was qualified,avoiding full batch return.The whole project took 11 days from arrival to release,12 days shorter than Mr.Chen’s expectation,and the comprehensive cost was reduced by about 8%.Mr.Chen later entrusted Zhongshen with the full year’s import plan of 30 containers.

## Practical Value of Professional Agents for Nantong Enterprises

For Nantong enterprises importing snack foods,it seems to be customs declaration procedures on the surface,but in essence it is a comprehensive test of the depth of understanding of regulations and the efficiency of communication with customs.The value of Zhongshen lies in translating 20 years of experience into executable solutions,and transforming uncertain quarantine risks into controllable processes.Customs supervision will continue to be digitalized in 2026,but the substantive review of food safety will not be weakened.The significance of professional agents is to allow Nantong importers to focus on market development and leave compliance problems to professionals.Choosing Zhongshen is equivalent to establishing a professional buffer zone between customs and foreign merchants,which not only ensures compliance,but also guarantees timeliness.

| Import Link | Risks of Independent Operation by Nantong Enterprises | Control Measures After Zhongshen’s Intervention |
| --- | --- | --- |
| Document pre-review | Insufficient identification of additive and label compliance,with an average rework rate of 40% | Standardized pre-review checklist,rework rate reduced to less than 5% |
| Port customs declaration | Risk of tax repayment caused by wrong HS code classification | Automatic database matching,accuracy rate of over 99% |
| Commodity inspection sampling | No rectification plan after unqualified testing,return rate of 30% | Simulate testing in advance,disposal success rate of unqualified products reaches 85% |
| Warehousing and distribution | Cargo damage caused by out-of-control temperature and humidity,loss rate of 8%-12% | Classified warehousing management,loss rate controlled within 2% |
