Full Process Breakdown of Korean Snack Import and Practical Customs Clearance Guide

In the 2026 food import market,Korean snacks still occupy a large share of import food shelves in China.From spicy fire chicken noodles to crispy seaweed,domestic consumer demand never fades.However,as practitioners with years of experience at Shanghai Port,we must remind all importers: the current customs clearance environment is no longer the era 10 years ago when goods can be released as long as complete documents are submitted.Especially for prepackaged food,the strict implementation of GACC Decree No.248 has caused many first-time importers to encounter setbacks at the port.Zhongshitong has handled countless return shipment cases caused by unqualified labels and unregistered factories.Today,we will skip vague theories and directly share core operation points and risk avoidance measures that must be noted in Korean snack import customs clearance in 2026.

GACC Decree No.248: Access Qualification is the First Critical Threshold

Many clients arrange shipment only with the Korean factory’s business license and health certificate,which is extremely risky.According to current regulations,all overseas food production enterprises that export food to China must complete the registration under the Administrative Measures for the Registration of Overseas Food Production Enterprises Imported to China (i.e.Decree No.248).This means your Korean supplier must be on the GACC registered enterprise list.

In actual operations,we have encountered a painful case from Ms.Nong.The batch of popular Korean chocolate she imported had excellent taste,but the Korean factory failed to update its registration information with Chinese customs after upgrading its production line,so the goods could not be declared after arrival.Finally,she had no choice but to return the goods to Korea or transit them to a third country,incurring losses of tens of thousands of yuan just on port detention fees and document exchange fees.

Therefore,before placing an order,you must ask the Korean supplier to provide its GACC registration number,and verify the information on the official GACC website.Do not arrange shipment if the supplier is not on the list,as no agency can clear the goods through customs illegally.

Chinese Label Review: Hidden Risks in Ingredient List and Additives

Chinese label is the top priority spot for customs inspection on imported food.Many importers assume that it is enough to ask a translation agency to translate the Korean text and stick it on the product,which is a total misconception.The 2026 commodity inspection focuses on "compliance",which requires all label content to meet mandatory national standards such as GB 7718 and GB 28050,and the core pain point lies in food additives.

Certain additives allowed for use in Korea may be strictly prohibited in China,or allowed for use but under different designated names.If you translate the Korean label directly,it will most likely be judged as unqualified by the commodity inspection authority.For example,some unique natural pigments or preservatives in Korea must be converted to the generic names specified in Chinese national standards in the Chinese label,and no ingredients unapproved by China can be included.

Conversion Traps of Nutrition Information Table

Korean snacks usually mark nutrition information per serving or per 100g,while Chinese standards require dual marking of nutrition information per 100g (or 100ml) and per serving.A more tricky issue is value rounding.There are slight differences between the Korean and Chinese value rounding rules.If you copy the Korean data directly,the sum of nutrient values will not be 100%,which will trigger an automatic alert in the customs verification system.

Zhongshitong’s suggestion is: before shipment,send the original label sample and ingredient list to a professional agency for pre-review.We usually leverage the database resources of Shanghai Port to compare the historical declaration elements of similar products,revise the label draft in advance,and ensure the goods pass the commodity inspection in one go after arrival.

Document Chain and RCEP Tariff Planning

As an RCEP member state,Korea enjoys preferential agreement tariff rates,but that does not mean you can automatically get the low tariff rate.To enjoy RCEP zero or low tariff,you must provide a certificate of origin that meets all official requirements.

In 2026 practical operations,customs has drastically intensified the verification of certificates of origin.For Korean snacks,the following document chain must form a complete logical closed loop:

• Official Certificate of Origin Must be issued by the Korean competent trade authority,with all information fully consistent with the bill of lading,commercial invoice,and packing list.
• Health Certificate Proves that the products meet human consumption standards.
• Component Analysis Report Used to verify the compliance of additives.
• Filling Date Certificate Many importers ignore this document,leading to disputes over shelf life calculation.

Special reminder: RCEP rules require "direct transportation".If your goods transit through a third country (though the China-Korea shipping route is usually direct),you need to provide a non-processing certificate.By making full use of RCEP rules,you can save thousands or even tens of thousands of yuan in tariff cost for one full container,which is tangible profit margin.

Shanghai Port Operation and Logistics Timing Control

As Zhongshitong’s core operating base,Shanghai Port has natural advantages in handling short-sea routes from Korea.Short-sea routes feature short transit time and high frequency,which put extremely high requirements on document accuracy and document cutoff time.Vessels from Korea depart on Thursday,arrive at Shanghai on Thursday,and pre-declaration usually needs to start as early as Monday.If documents are still under modification at that time,you will incur customs declaration delay fees.

In addition,though the food inspection rate at Shanghai Customs remains stable,once the goods are selected for inspection,the sampling and testing cycle is uncontrollable.Testing of microorganisms,heavy metals,and preservatives takes time.For baked snacks with short shelf life,the process is a race against time.

We usually recommend clients to adopt the "bonded warehousing" strategy.Declare the goods to the bonded zone first,conduct label rectification and sorting inside the zone,and complete customs clearance and delivery after formal orders are confirmed.This measure effectively avoids container detention fees at port,and reserves sufficient buffer time for commodity inspection.

Customs Valuation and Foreign Exchange Risk

Do not assume that you can save tax by under-declaring the goods value.The 2026 customs valuation system is connected to big data networks.For popular Korean snacks,customs maintains an internal "price risk database".If your declared value is lower than the average level of products of the same brand and specification,the system will automatically trigger a valuation query.

Once the price is queried,you need to provide foreign exchange payment vouchers,insurance policies,and even the original invoices from the manufacturer to prove the authenticity of the trade background.If you cannot provide the required documents,customs will assess and impose tax according to the assessed value,which not only requires supplementary tax payment,but also may lead to administrative penalties.Zhongshitong always adheres to truthful declaration,and obtains tariff reduction through compliant classification and RCEP preferential policies,which is the proper and legal path.

Practical Case Review: S-T-A-R Principle

Last year,Manager Tang contacted us,as a batch of Korean beverages he imported was stuck at the terminal.Situation: after the goods arrived and were declared,the customs system issued an inspection instruction targeting the product labels.Task: resolve the label issue within 2 days,or the goods would be destroyed due to approaching expiration.Action: we immediately coordinated with the Shanghai Customs inspection department,applied for on-site inspection at the designated supervised warehouse,and found that the "energy" unit on the original label used "kcal" instead of the national standard required "kJ",and the trans-fatty acid content was not marked.We produced compliant self-adhesive labels overnight,and assigned dedicated staff to apply the labels under customs supervision.Result: the goods were smoothly released.Though some rectification operation fees were incurred,the loss of hundreds of thousands of yuan from destruction of the whole container was avoided.
