Cassia Seed Import Customs Declaration Agency: Full Process Guide from Document Pre-check to Port Inspection

Background and Core Difficulties of Cassia Seed Import Trade

As a traditional Chinese medicine and health product raw material,the annual domestic demand for cassia seed has exceeded 8,000 tons in 2026,with more than 60% dependent on imports from major producing countries such as India,Myanmar and Nigeria.Cassia seed grown in these regions has the characteristics of full grains and high active ingredient content,but the import process is not smooth.In 2026,the customs has implemented stricter access management for plant-derived traditional Chinese medicines,adding 5 pesticide residue test indicators,and fully aligning heavy metal limit standards with the Codex Alimentarius Commission (CAC).Most import enterprises feedback that inconsistent documents,substandard quarantine and long inspection cycle have become the three main obstacles.For enterprises operating for the first time,the average customs clearance time is as long as 25-30 working days,far exceeding the 5-7 day cycle of general cargo.

Zhongshen has been deeply engaged in the foreign trade agency field for more than 20 years,and has handled more than 300 cassia seed import batches in total.We are familiar with the operation practices of major shipping ports such as Nagpur Port in India and Yangon Port in Myanmar,and also understand the differences in inspection priorities of domestic ports such as Shanghai,Guangzhou and Tianjin.Through systematic process control and pre-risk investigation,we can shorten the average customs clearance time of cassia seed to 12-15 working days,while controlling the inspection abnormality rate within 5%.

Core Role and Value Orientation of Import Agency Services

Zhongshen’s service is not just document transfer or errand running.We play the dual roles of compliance planner and risk firewall.In the cassia seed import project,our team will intervene before the contract is signed,assist customers in reviewing the qualifications of foreign suppliers,and confirm whether they are on the China Customs access list.In 2026,the General Administration of Customs implemented dynamic credit ratings for Indian cassia seed export enterprises.Some enterprises had their qualifications suspended due to quarantine issues.We warned customers in advance to replace suppliers,avoiding the loss of three batches of goods being returned after arrival.

Our value is reflected in three aspects: First,accurate interpretation of regulations.For example,the revised version of the "Measures for the Quarantine and Supervision of Imported Traditional Chinese Medicines" implemented in March 2026 requires that cassia seed must provide an official plant quarantine certificate issued by the agricultural department of the exporting country,plus 10 detailed information such as Latin scientific name and harvest date.Many enterprises had their goods detained due to inconsistent certificate formats.Second,optimize logistics paths.According to the quantity of goods and delivery date,we recommend different schemes of FCL,LCL or air freight to balance cost and timeliness.Third,emergency response capability.When goods are selected for laboratory testing,we coordinate the port laboratory to give priority to urgent processing and prepare backup plans to ensure that the customer’s production line does not stop due to material shortage.

Full Process Breakdown of Cassia Seed Import Customs Declaration

Document Pre-check and Compliance Confirmation

Document pre-check is the most critical pre-link to avoid risks.The core documents required for cassia seed import include: certificate of origin,plant quarantine certificate,packing list,invoice,contract,bill of lading,pesticide residue and heavy metal test report,and Chinese label sample.Zhongshen’s operation specification is to collect all scanned documents for cross-check within 7 working days before the goods are loaded.

We focus on checking three high-risk points: First,whether the plant quarantine certificate indicates the accurate Latin scientific name "Cassia obtusifolia L.".In 2026,multiple batches of goods were detained due to inconsistent species identification caused by writing "Cassia tora".Second,whether the test report covers the 19 pesticide residue indicators stipulated by China.Some foreign laboratories only test 12 items of EU standards,and the missing 7 items must be retested before loading.Third,whether the Chinese label complies with the "National Food Safety Standard for General Principles of Prepackaged Food Labels".As a substance that is both medicine and food,cassia seed must be marked with the warning "This product cannot replace medicine" on the label,and the font height shall not be less than 1.8 mm.We once served a health product company operated by Mr.Shi.Its first batch of imported labels was required to be rectified at the port because the warning was not marked.We coordinated the printing factory to rework overnight,avoiding high storage fees caused by overdue detention of goods.

Port Customs Declaration and Tax Accounting

The core of the customs declaration link is accurate classification and declaration element filling.Cassia seed is classified under customs commodity code 1211905099 (other plants mainly used as medicinal materials).In 2026,the most-favored-nation tariff rate is 6%,and the value-added tax is 9%.Zhongshen’s customs declarers will carefully check the declaration elements: product name,Latin scientific name,purpose (medicinal/edible),whether it has been chemically treated,packaging specifications and brand.The "purpose" column is particularly critical.Declaring it as medicinal can enjoy the rapid inspection channel of some ports,but subsequent procurement certificates from drug manufacturers are required; declaring it as edible will face stricter food safety index inspection.

In terms of tax accounting,we provide customers with CIF cost actuarial services.Take a batch of 20 tons of cassia seed imported from India in June 2026 as an example: the CIF Shanghai unit price is 1.85 USD/kg,the exchange rate is 7.25,and the total value is 267,625 RMB.The tariff is 16,057.5 RMB,the value-added tax is 25,531.58 RMB,and the total tax is 41,589.08 RMB.We inform customers in advance of the tax funds to be prepared,and complete the margin payment filing before the goods arrive at the port,ensuring that the goods can be released on the day of customs declaration without delaying the pickup plan.

Commodity Inspection and Laboratory Testing

Commodity inspection is the most uncertain link in cassia seed import.In 2026,the customs implements 100% on-site inspection for plant-derived traditional Chinese medicines.The inspection contents include: packaging integrity,presence of mold and pests,label compliance,and sensory properties.Zhongshen’s on-site inspection coordinators will arrive in advance,prepare sample extraction tools and sample retention bags,and cooperate with customs inspection.

There are three outcomes after inspection: First,direct release,accounting for about 30%,applicable to batches with complete documents,good goods status and non-first-time imports.Second,sampling for testing,accounting for about 65%,and the laboratory testing cycle is usually 10-15 working days.The testing items include 19 pesticide residues,5 heavy metals (lead,cadmium,mercury,arsenic,copper) and aflatoxin.We have established a port laboratory green channel database,which can be shortened to 7 working days for urgent samples.Third,abnormal disposal,accounting for about 5%.If live insects,mold or serious label inconsistencies are found,fumigation,rectification or return will be faced.Last year,a batch of Myanmar cassia seed we handled was found to have a small amount of mold.We immediately activated the emergency plan,coordinated the port’s professional fumigation company to implement ethylene oxide fumigation under customs supervision,and passed the re-inspection and release after 3 days,saving the customer a loss of nearly 300,000 RMB in cargo value.

Actual Case: India Cassia Seed Import Project of Mr.Shi’s Company

Mr.Shi operates a medium-sized health product manufacturing enterprise in Shanghai.In early 2026,he planned to import 50 tons of cassia seed from India as raw materials for new products.This was the company’s first independent operation of traditional Chinese medicine import,and they had no concept of the process and risks.After contacting Zhongshen,we first conducted a qualification investigation on its Indian supplier.Although the exporter was on the customs access list,it had two records of inconsistent certificates in 2025,with a risk rating of Grade B.We advised Mr.Shi to require the supplier to add an additional statement to the official certificate and purchase pre-shipment inspection services.

The goods arrived at Shanghai Waigaoqiao Port on March 15,2026.The document pre-check we completed in advance ensured zero errors in the declaration materials.However,the goods were selected for laboratory testing during inspection,and the testing cycle was expected to be 12 working days.Mr.Shi’s production line was scheduled to start production on April 1,and the time was very tight.We activated the emergency mechanism: on the one hand,we coordinated the laboratory to give priority to scheduling; on the other hand,we contacted backup inventory for Mr.Shi,transferring 5 tons of cassia seed of the same specification from our bonded warehouse in Songjiang to ensure that his production line started first.The final test report was issued on March 28,and all indicators were qualified.After the goods were released,we arranged vehicles to send them directly to Mr.Shi’s factory.The entire project took only 13 working days from arrival to production,half the conventional cycle.Mr.Shi later feedback that without our intervention,this batch of goods would likely have been rejected at the source due to supplier qualification issues,or delayed the production plan due to the testing cycle,and the loss would have been incalculable.

Summary of Zhongshen’s Professional Agency Value

The complexity of cassia seed import customs declaration stems from the intersection of professional supervision of traditional Chinese medicines and international trade rules.Zhongshen’s 20 years of experience allows us to predict risks,optimize processes and handle emergencies.Our services are directly translated into three major benefits for customers: reduced time costs,with the average customs clearance time shortened from the industry average of 25 days to less than 15 days; controllable financial costs,with an extra savings of 3,000-8,000 RMB per batch through accurate tax accounting and demurrage-free operations; minimized compliance risks,with our pre-check mechanism reducing the inspection abnormality rate from the industry average of 15% to less than 5%.

The regulatory environment in 2026 will only become stricter.The General Administration of Customs has clearly included traditional Chinese medicines in the strictest food safety supervision category.For enterprises without a professional customs declaration team,choosing a senior agency like Zhongshen is not an increase in cost,but a necessary investment to avoid risks and ensure supply chain stability.What we provide is not just document processing,but a complete import solution,allowing customers to focus on product R&D and market expansion,and hand over complex customs declaration matters to professional teams.
