Zhongshen Seasoning Import Customs Brokerage Services: Professional Services Covering Document Pre-Audit, Commodity Inspection and Quarantine, and International Transportation Across the Entire Process

In 2026,China’s seasoning import market shows a diversified trend,with steady growth in demand for products such as fish sauce and Thai chili sauce from Southeast Asia,olive oil and balsamic vinegar from Europe,and miso and soy sauce from Japan and South Korea.However,when importing seasonings from these regions,enterprises generally face difficulties such as tedious document preparation,strict quarantine standards,and frequent updates to label regulations.A food trading company in East China once had its cargo detained at the port for two weeks due to failure to provide the original health certificate for Thai fish sauce,resulting in additional storage costs.Similar situations are common among small and medium-sized enterprises.

Zhongshen,headquartered in Shanghai and a professional foreign trade import and export agency with over 20 years of industry experience,provides end-to-end services from customs declaration and inspection to warehousing and transportation to address the complexity of seasoning imports.Ms.Bai stated that seasonings fall under the food category,and the import process involves multiple documents such as health certificates and ingredient analysis reports.Any oversight could lead to port detention or cargo rejection.The value of an agency lies in intervening early and systematically managing risks at each stage.

Professional Stage-by-Stage Analysis of Seasoning Import Agency Services

Zhongshen divides the seasoning import agency process into four key stages,each corresponding to specific compliance requirements and operational key points.

Stage 1: Document Pre-Audit and Procurement Coordination

Document preparation is the foundation before seasoning imports.In 2026,China Customs has more detailed requirements for food-related documents.In addition to conventional contracts,invoices,and packing lists,official health certificates,certificates of origin,and ingredient test reports issued by the exporting country are also required.For seasonings containing additives,such as preservatives in soy sauce and pigments in chili sauce,the specific content must be labeled and comply with GB2760 standards.General Manager Hao pointed out that many enterprises have documents submitted with missing key information because foreign suppliers are unfamiliar with Chinese regulations.

Zhongshen’s approach is to provide document checklist templates and assist customers in communicating with overseas suppliers.For example,when importing Italian balsamic vinegar,the team will pre-audit whether the acidity and sugar content indicators are within the range stated on the label.The following table compares the special document requirements for common seasonings:

Through pre-audit,Zhongshen has reduced the document rejection rate by an average of 70%,avoiding delays in subsequent stages.

Stage 2: Port Customs Declaration and Tax Calculation

After seasonings arrive at the port,customs declaration must accurately match the commodity code and regulatory conditions.In 2026,the General Administration of Customs subdivided the commodity codes for seasonings.For example,soy sauce is classified under 2103.1010,with a tariff rate of 10% and a value-added tax rate of 9%.Incorrect declaration may trigger customs inspection or additional tax payments.Manager Xie mentioned that a customer once declared flavored oil as edible vegetable oil,resulting in additional tax payments due to code differences.

Zhongshen’s customs declaration team will determine the code based on the specific ingredients of the product and calculate comprehensive taxes and fees.The services include:

• Verify commodity codes and declaration elements to ensure consistency with documents;
• Submit customs declaration forms and simultaneously apply for inspection and quarantine notices;
• Calculate tariffs,value-added tax,and possible anti-dumping duties;
• Track customs declaration status and promptly respond to customs inquiries.

For seasonings from free trade agreement regions such as ASEAN,the agency will assist in applying for preferential tariff rates and provide certificate of origin verification.In the first quarter of 2026,the average customs clearance time for seasoning imports handled by Zhongshen was shortened to 3.5 days,lower than the industry average of 7 days.

Stage 3: Commodity Inspection and Quarantine,and Label Rectification

Seasonings are subject to mandatory legal inspection and quarantine,and port customs conduct sampling tests based on risk levels.Test items include microorganisms (Salmonella,E.coli),additives (benzoic acid,sorbic acid),heavy metals (lead,arsenic),etc.The 2026 new regulations require that seasoning labels must be in Chinese,and the nutritional composition table must be calculated per 100 grams or 100 milliliters.Mr.Zhuo shared a case where a batch of Korean kimchi sauce was required to be rectified and released because the label did not indicate the fermentation strain.

Zhongshen provides full accompanying services during the quarantine process:

• Prepare samples in advance and send them to a third-party laboratory for pre-inspection to ensure compliance with national standards;
• Assist in making Chinese labels and review whether the content complies with GB7718;
• Cooperate with customs sampling and promptly respond to test results;
• If non-compliance is found,assist customers in negotiating with suppliers for cargo return or destruction.

The team has also established a quarantine database for common seasonings,focusing on high-risk items from different source regions.For example,Southeast Asian seasonings focus on mycotoxins,while European products focus on additive compliance.

Stage 4: Warehouse Management and Domestic Distribution

After customs clearance is completed,seasonings must enter warehouses that meet food storage conditions.In 2026,the Shanghai Port implemented classified management for imported food warehouses,requiring constant temperature and humidity,pest and rodent control.All warehouses partnered by Zhongshen have passed ISO22000 certification and provide value-added services such as sorting,labeling,and packaging.Director Hu pointed out that seasonings such as olive oil need to be stored away from light,and chili sauce needs to avoid high temperatures.Improper warehouse management will affect product quality.

The agency services cover warehousing to door-to-door transportation:

• Arrange bonded or non-bonded warehousing based on product characteristics;
• Implement inventory information management to update in and out warehouse data in real time;
• Coordinate with customer sales plans and arrange domestic logistics distribution;
• Handle follow-up procedures for defective cargo return or destruction.

By integrating warehousing and transportation resources,Zhongshen helps customers reduce intermediate costs and improve supply chain response speed.

Actual Case: Avoiding Quarantine Risks in Fish Sauce Imports

In late 2025,a catering company in Shenzhen planned to import a batch of fish sauce from Thailand for seasoning in its chain stores.The company contacted the Thai supplier on its own,but the health certificate provided by the supplier did not indicate the specific variety of fish raw materials,and the test report lacked histamine indicators.After Zhongshen intervened,Director Hu recommended suspending shipment and guided the supplier to supplement the documents.The team reviewed the 2026 latest import regulations for aquatic products and found that excessive histamine is a common problem with Southeast Asian fish sauce,which may cause food safety risks.

Zhongshen arranged for a third-party laboratory to conduct histamine tests on the samples,and the results were close to the limit.The team negotiated with the supplier to adjust the production process,reduce histamine content,and reissue a health certificate compliant with Chinese regulations.After the cargo arrived at the port,the customs sampling test passed,and customs clearance was completed within one week.The company avoided possible cargo return losses and ensured the product was launched on schedule.General Manager Hao summarized that the professionalism of seasoning import agencies is reflected in attention to details,especially the hidden indicators of food safety.

Summary: Value of Professional Agencies and Future Trends

In 2026,seasoning import agencies have shifted from simple customs clearance services to full-process compliance management.With 20 years of experience accumulation,Zhongshen has built an integrated platform covering documents,customs declaration,commodity inspection,and warehousing.Ms.Bai believes that as global food regulations converge,agencies need to continuously update their knowledge base to meet new technical requirements such as label digitization and traceability blockchain.

For importing enterprises,choosing a professional agency not only improves efficiency but,more importantly,reduces compliance risks.Customer feedback from Zhongshen shows that agency services reduce average customs clearance time by 30% and reduce quarantine non-compliance rates by 50%.Against the backdrop of increasingly complex seasoning trade,professional support from agencies has become an important guarantee for enterprises to steadily expand their import business.
