Full Process Analysis and Key Compliance Interpretation of Thai Tom Yum Paste Import Agency Service

Market Background and Operational Difficulties for Importing Thai Tom Yum Paste

In the first quarter of 2026,the import volume of Thai condiments at Shanghai Port increased by 23% year-on-year,among which the proportion of tom yum paste exceeded 40%.This fermented compound seasoning,based on plant spices such as lemongrass,kaffir lime leaves and galangal,has reached a penetration rate of 67% in catering channels in the Yangtze River Delta.However,many importers new to this category find that even this seemingly standardized pre-packaged food hides multiple compliance thresholds in actual operation.

Quarantine inspection for plant-derived ingredients is the primary threshold.Tom yum paste usually contains lemongrass,kaffir lime leaves,chili,shrimp paste and other ingredients,and some high-end products also add lemongrass essential oil.According to the 2026 revised List of Entry Quarantine for Plant-derived Food,the above ingredients require a phytosanitary certificate issued by the Ministry of Agriculture of Thailand,fumigation treatment certificate,and the registration number of an overseas production enterprise approved by Chinese authorities.At the beginning of this year,a manager once encountered a shipment of tom yum paste worth 800,000 Thai baht that was ordered to be fully returned by Huangpu Laogang Customs because the lemongrass ingredient was not included in the registered product list.

Compliance review of food additives is also tricky.Thai factories often use potassium sorbate and sodium benzoate as preservatives,and some products add monosodium glutamate to enhance freshness.The 2026 revised Standard for the Use of Food Additives released by the National Health Commission imposes stricter limits on preservative residues in compound seasonings.Importers need to check the additive items in the Thai inspection report batch by batch to ensure they fully comply with Chinese national standards.In the label review process,the Chinese label must clearly indicate allergen information (shrimp paste ingredient),fermentation process description,and a nutrition facts table that meets GB 28050.Any error in font height or unit marking may lead to rectification requirements.

Core Role of Zhongshen in Importing Thai Tom Yum Paste

Zhongshen has been handling Thai food import business since 2008,and has completed customs clearance for more than 600 batches of tom yum paste.Our value does not lie in simple document submission,but in identifying risk nodes in advance.In March 2026,a Suzhou-based catering supply chain enterprise we serve planned to introduce a Thai brand of tom yum paste.Before the contract was signed,we sent the obtained sample for inspection immediately,and found that the shrimp paste raw material came from a small workshop that was not included in the list of registered Thai aquatic product enterprises published by the General Administration of Customs.This pre-emptive action helped the client avoid potential losses of approximately 450,000 RMB.

Our operation logic is: embed compliance review at the very front of the trade process.From supplier qualification verification,formula component pre-audit,label draft design,to transportation mode selection and port layout planning,each link is built on real-time interpretation of the latest 2026 regulatory policies.This in-depth intervention mode makes the average customs clearance time of our tom yum paste import business 4.2 working days faster than the industry average,and the inspection rate is controlled within 8%.

Phased Decomposition of Import Process and Compliance Key Points

Document Pre-review Stage: Risk Identification Window

Document pre-review is not a simple check of document completeness,but a golden window for risk identification.For tom yum paste,we focus on verifying five types of documents:

• The phytosanitary certificate issued by the Thai official must indicate the Latin scientific name and treatment measures of plant-derived ingredients such as lemongrass and kaffir lime leaves
• The registration number of the overseas production enterprise must be checked for its valid status in the "Import Food Overseas Production Enterprise Registration System" of the General Administration of Customs
• The ingredient ratio table,which is accurate to the CAS number and addition amount of each additive
• Source certificate of shrimp paste raw materials,including fishing area and processing factory registration information
• Original label and Chinese translation,check whether the allergen label is complete

In April 2026,we handled a shipment of tom yum paste shipped from Bangkok.During pre-review,we found that the Latin scientific name of kaffir lime leaves was misspelled on the phytosanitary certificate provided by the Thai side.We immediately contacted the Thai exporter to re-apply for the certificate and completed the correction before the ship arrived at the port,avoiding container demurrage charges.

Port Customs Declaration Stage: Accurate Matching of Declaration Elements

The filling of declaration elements in the customs declaration link directly determines the probability of inspection.Tom yum paste is usually classified under HS code 2103.9090 (Other seasoning sauces),but some products with shrimp paste proportion exceeding 20% may be classified under 1605.9090 (Other prepared or preserved crustaceans).This classification difference affects tariff rates and supervision conditions.Zhongshen will communicate with the local customs for pre-classification in advance based on the product formula and process description.

Declared price is also a key focus.The ex-factory price of Thai tom yum paste is generally 30-50 Thai baht per bottle,but some brands have a high premium in the Chinese market.The customs price verification system will capture the recent import prices of similar goods for comparison.We will assist clients to prepare complete pricing instructions,including brand authorization agreements,market promotion expense allocation certificates,etc.to ensure that the declared price conforms to the definition of transaction value.

Commodity Inspection Stage: Laboratory Testing and Label Rectification

The core of the commodity inspection link is laboratory testing.In 2026,the sampling items for Thai tom yum paste at Shanghai Port include: preservative residue,microbial indicators (Salmonella,Staphylococcus aureus),heavy metals (lead,arsenic),and DNA testing of plant-derived ingredients.The testing cycle is usually 7-10 working days.

Label rectification is another high-frequency problem.We once handled a case: the high-end tom yum paste imported by the client was labeled "shrimp extract" instead of "shrimp paste" on the Chinese label,which was judged as misleading description.We assisted the client to redesign the label,marked it as "shrimp paste (shrimp,salt)" in the ingredient list,and clearly prompted "contains crustacean products" in the allergen information column.It passed the inspection smoothly after rectification.

Practical Case: Avoiding Return Risk of Lemongrass Ingredient

In May 2026,Mr.Li,a Shanghai importer,planned to introduce tom yum paste produced by a Thai factory,with the first order of 1,200 cartons.During the contract negotiation stage,Zhongshen intervened to review the product formula and found that the lemongrass used was a wild harvested variety in Thailand,which was not included in the filing list of the Protocol on Inspection and Quarantine Cooperation for Sino-Thai Plant-derived Food.According to the 2026 new regulation,unfiled plant ingredients require additional risk assessment reports.

We adopted a three-step solution: First,contact the Thai supplier to obtain the botanical identification report and collection area map of the lemongrass origin; second,entrust a third-party laboratory to conduct component safety assessment; third,submit an application for Import Animal and Plant Quarantine Permit to the General Administration of Customs,attaching the above materials.The entire pre-work took 18 working days,and we obtained the permit before the goods were loaded.After the goods arrived at the port,the customs only conducted document review,no container opening inspection,and completed release within 3 working days.Mr.Li’s shipment finally entered the sales channel one week earlier than originally planned,catching the peak catering procurement season of the Dragon Boat Festival.

Value Embodiment of Professional Agency

The professionalism of importing tom yum paste is reflected in the control of details.Zhongshen has established a Thai food import database,which includes registration information of 47 Thai factories,compliance records of more than 200 formulas,and inspection preferences of various ports.In 2026,we launched the "pre-inspection and pre-verification" service,which provides free rapid assessment of sample compliance before customers officially place an order,and gives rectification suggestions after identifying risk points.

The direct benefit of this in-depth service model is cost saving.According to our internal statistics,for the tom yum paste business operated in the first half of 2026,the average potential loss saved by customers through early risk avoidance reached 12% of the cargo value.The indirect benefit is time efficiency.Our customers get goods 5-7 days earlier than their peers on average,which means stronger market competitiveness in seasonal procurement of the catering industry.

Importing tom yum paste is not a simple buying and selling behavior,but a systematic project supported by cross-professional knowledge.From the fields in Thailand to the dining tables in China,each link has corresponding compliance requirements.The knowledge base and operation process built by Zhongshen over 20 years essentially build a firewall for customers,turning uncertain risks into predictable costs.
