Complex Customs Declaration Process for Differential Taxation Import Goods? Professional Agency Services Help You Mitigate Risks

Background and Operational Difficulties of Importing Brazilian Frozen Beef

In the first quarter of 2026,the domestic meat consumption market continued to recover.Brazilian frozen beef has steadily increased its import market share thanks to its price advantages and quality stability.This type of goods is a typical differential taxation category,where value-added tax is calculated under the differential taxation mode,involving multiple regulatory dimensions such as customs valuation,origin certification,and quarantine approval.In actual operations,enterprises often face three practical obstacles: First,the format of commercial invoices provided by Brazilian suppliers differs from domestic tax filing requirements,making it easy to make mistakes in confirming the differential taxation base; Second,the versions of meat product quarantine certificates are updated frequently,and the 2026 new version adds animal welfare traceability codes,leading to a higher rate of returns due to document discrepancies; Third,in the port inspection link,customs has become stricter in verifying the temperature records of frozen meat containers and inner package labels,and cases where a batch of goods was detained due to missing temperature probe data are not uncommon.

When undertaking such businesses,the primary task of Zhongshen is to clarify the regulatory characteristics of the products.For frozen beef as a differential taxation good,its taxable price is not simply based on the contract amount,but needs to deduct specific expense items.This requires the agency to intervene in the design of trade terms in advance,and clarify which expenses are not included in the dutiable value during the contract negotiation stage.Manager Yu mentioned that at the end of 2025,a Shanghai food service supply chain enterprise it served initially signed a DDP term contract with Brazilian suppliers,which included domestic transportation fees.This part of the fees could have been deducted from the tax base,but because the contract did not clearly list them separately,it almost resulted in overpayment of taxes.

Compliance Key Points in the Document Pre-examination Stage

Document pre-examination is the first line of defense to avoid subsequent risks.The operating specifications of Zhongshen require that the logical verification of all documents must be completed before the goods are loaded onto the ship.The specific audit list includes: scanned copies of the original sanitary certificates issued by the Ministry of Agriculture of Brazil,certificate of origin certified by the consulate,composition analysis report issued by the supplier,and cross-checking of packing list and commercial invoice.

• For the sanitary certificate,focus on checking whether the newly added animal welfare traceability code in the 2026 version matches the Brazilian official database.The validity period of the certificate has been shortened from the original 90 days to 60 days,and a re-application is required if expired
• The tariff code on the certificate of origin must be completely consistent with the declaration on the customs declaration form.Some Brazilian exporters habitually use NCM codes,which need to be accurately converted to China’s HS codes.The conversion rules for meat products in Chapter 16 have been slightly adjusted in 2026
• The commercial invoice must clearly list the FOB price,sea freight and insurance premiums.The deductible items for differential taxation must be marked separately and not mixed into the total price
• The composition analysis report must include three core indicators: moisture,protein and fat.If the values exceed the allowable floating range of national standards,it may be认定 as incorrect classification

Manager Yu shared a typical case: In February 2026,the composition report of a Brazilian factory provided by a Jiangsu importer showed a protein content of 18.5%,while the national standard requires no less than 19%.After the goods arrived at the port,the customs questioned the classification as "other meat products",with the tax rate adjusted from 12% to 20%,and the differential taxation base also changed accordingly.Zhongshen discovered this problem during the pre-examination stage,timely coordinated the Brazilian factory to re-submit the test,and obtained the revised report before loading the goods,avoiding subsequent disputes.

Precise Operations in the Port Customs Declaration Stage

After the goods arrive at Yangshan Port or Waigaoqiao Port,the timeliness of the customs declaration stage directly affects the storage cost.As perishable goods,frozen beef enjoys the "prior declaration" convenience measure provided by the customs,but the particularity of differential taxation goods requires higher accuracy in declaration elements.The customs declaration team of Zhongshen will submit the pre-recorded form 48 hours before the ship arrives at the port,focusing on three technical details:

First,accurate selection of supervision methods.After the customs system upgrade in 2026,differential taxation goods must be marked with "differential taxation" in the filing column and associated with the previously filed *Import Goods Price Declaration Form*.This form needs to be submitted to the Customs Tariff Office in advance,with an approval period of about 3 working days.Many new customers fail to declare the goods in time after arrival because they are unaware of this pre-requirement.

Second,accuracy of commodity classification.Brazilian frozen beef is classified under different sub-items under 0202 or 0203 according to the cut parts.The tax rate difference between shoulder meat,rib chops and hind leg meat is between 2 and 3 percentage points.The classification specialist of Zhongshen will conduct pre-classification based on the cutting map of the Brazilian factory and actual goods photos.In 2026,the General Administration of Customs of China issued Classification Decision No.5,which clarifies the definition standards for boneless and bone-in products,and this change directly affects the calculation base of differential taxation.

Third,reasonableness of price declaration.The customs has internal risk parameters for the import price of Brazilian beef.If the declared unit price deviates from the average market price of the same period by more than 15%,the system will automatically transfer to manual price verification.Zhongshen has established a price database of major Brazilian exporters,updating the reference average price every week,to help customers control the declared price within a reasonable range.In March 2026,a batch of beef brisket declared at 3.2 USD/kg was subject to price verification because it was lower than the risk parameter.Zhongshen quickly provided the transaction proof from the Brazilian Sao Paulo Exchange in the same period and supporting materials for the increase in shipping costs,and finally the goods were released at the declared price.

Response Strategies for Commodity Inspection and Quarantine

Meat products are statutory inspection commodities with a relatively high port inspection rate.In 2026,the customs focuses on three aspects when inspecting frozen beef: the continuity of temperature during container transportation,the compliance of inner package labels,and veterinary drug residue testing.

Temperature records are the primary inspection item.The customs requires that containers must be equipped with more than three temperature probes to record temperature data throughout the journey,with a data interval of no more than 30 minutes.Zhongshen will check the operating status of the temperature recording equipment during the document exchange link,and immediately coordinate the shipping company to issue a statement if there is missing or abnormal data.In January 2026,a container from the Port of Santos had 6 hours of temperature data interruption due to a mid-journey cold unit replacement,which was questioned during customs inspection.Manager Yu’s team prepared the shipping company’s mechanical maintenance records and operation certificates from the Brazilian port in advance,explaining that the data interruption was due to equipment failure rather than abnormal goods,finally avoiding container inspection and saving at least two days of clearance time.

The inspection of inner package labels has become increasingly strict.According to the revised *Measures for the Supervision and Administration of Imported Meat Products Inspection and Quarantine* implemented in 2026,labels must be marked in both Portuguese and Chinese,including product name,specification,production date,shelf life,storage conditions,and registration number of the production enterprise.Zhongshen will require the Brazilian factory to provide label samples for pre-examination before the goods are loaded onto the ship,and the Chinese translation must be accurate,especially the product name should not have misleading expressions such as "snowflake beef".There was a case where a batch of goods was labeled "brisket" translated as "beef brisket",but the customs认定 that it should be translated as "beef brisket plate",requiring rectification.Zhongshen coordinated to reapply compliant labels in the bonded warehouse before the goods were released.

Veterinary drug residue testing is another high-risk point.Some regions in Brazil have a history of using ractopamine,although the authorities claim it has been banned,but customs spot checks will still focus on this item.Zhongshen advises customers to choose factories with Brazilian SIF number above 4500,which have passed EU certification and have a more complete veterinary drug control system.At the same time,it will require suppliers to provide self-inspection reports on veterinary drug residues for each batch of goods.Although this is not a statutory document,it can be used as auxiliary evidence during customs inspection to speed up the release process.

Practical Tax Treatment for Differential Taxation

The core of differential taxation is to accurately calculate the taxable base.For Brazilian frozen beef,the items that can be deducted from the dutiable value include: transportation costs,insurance fees before the goods arrive at the Chinese customs boundary,and eligible agency fees and commissions.After the customs declaration is completed,the financial team of Zhongshen will assist customers in sorting out the *Import Link VAT Differential Taxation Detailed List*,which needs to correspond one-to-one with the customs declaration form and serve as the basis for tax declaration.

In 2026,the State Taxation Administration has refined the filing requirements for differential taxation,requiring enterprises to provide scanned copies of the original expense vouchers,and the expense items on the vouchers must be completely consistent with the deduction items in the remarks column of the customs declaration form.Zhongshen has established a standardized expense splitting template,and when Brazilian suppliers issue invoices,it will guide them to list sea freight and insurance premiums separately,avoiding the dilemma of unable to deduct expenses later.

Manager Yu specifically reminded that in 2026,the customs and tax systems realized data interconnection,and the price information on the customs declaration form will be automatically synchronized to the tax system.If the deduction items declared by the enterprise do not match the remarks on the customs declaration form,the system will automatically issue an alert.Zhongshen will synchronously generate the expense list required for tax declaration during the customs declaration stage,ensuring the consistency of customs and tax data.

Case Sharing: Mitigating Dual Risks of Exchange Rate Fluctuations and Policy Changes

In April 2026,a large food processing enterprise in Shanghai planned to import 120 tons of frozen beef shank from Brazil,with a contract amount of about 600,000 USD.At that time,the exchange rate of the Brazilian real fluctuated sharply,depreciating by more than 8% within a week.The customer was worried about excessive exchange rate losses when making payments and wanted to use RMB for settlement.However,Brazilian suppliers insisted on receiving USD,and the two sides reached an impasse.At the same time,starting from May 1,2026,China adjusted the tariff quota policy for Brazilian beef,and the tariff rate for the part exceeding the quota increased from 12% to 25%.The customer hoped that the goods could arrive at the port and clear customs before the end of April.

The solution of Zhongshen is divided into three steps: First,using the company’s credit line in the bank,it handled forward foreign exchange settlement and sale business for the customer,locking in the exchange rate of 7.28 to purchase foreign exchange on April 25,avoiding exchange rate risks.Second,it coordinated with Brazilian suppliers to ship the goods in two batches.The first batch of 80 tons was arranged to be shipped on April 15 to ensure arrival before the quota policy adjustment; the second batch of 40 tons arrived after the policy adjustment,and Zhongshen assisted the customer in applying for a special tariff quota,finally clearing customs at a preferential tax rate of 15%.Third,during the differential taxation declaration,the sea freight of the first batch of goods was deducted according to the pre-adjustment standard,and the second batch was deducted according to the new standard,and they were accounted for separately to avoid tax confusion.

The difficulty of this case lies in the precise control of the time node.The logistics team of Zhongshen tracked the ship dynamics every day.The first batch of goods was originally scheduled to arrive at Yangshan Port on April 28,but it might be delayed to May 2 due to shipping schedule delays.Manager Yu urgently coordinated the shipping company to change the port calling order,giving priority to arranging the ship to unload other goods at Ningbo Port,and finally ensured that the ship arrived in Shanghai on the evening of April 30,catching up with the policy deadline.The entire operation saved the customer about 180,000 yuan in tariff costs,and the exchange rate lock also avoided a foreign exchange loss of nearly 100,000 yuan.

Extended Value of Full-process Services

After completing customs clearance and tax declaration,the services of Zhongshen do not end.For commodities that require cold chain storage such as frozen beef,Zhongshen provides bonded warehouse temporary storage services.Customers can handle outbound delivery and VAT payment in batches according to the domestic sales progress,easing financial pressure.In 2026,the area of bonded cold storage in the Shanghai Free Trade Zone operated by Zhongshen has expanded to 5,000 square meters,with temperature zones controlled between -18℃ and -22℃ to meet the needs of different customers.

In the subsequent foreign exchange verification link,Zhongshen will assist customers in matching customs declaration forms and payment records to ensure the balance of data in the foreign exchange monitoring system.Especially for differential taxation goods,since there is a difference between the taxable price and the payment amount,the foreign exchange administration bureau sometimes raises questions.Zhongshen has prepared a standardized statement template to explain the tax treatment logic of differential taxation,helping customers pass the foreign exchange inspection smoothly.

With 20 years of industry accumulation,Zhongshen has established a complete import database for Brazilian frozen beef,covering price trends of major Brazilian exporters,customs price verification parameters,changes in inspection key points and other information.After each import,Zhongshen will enter the operation time,cost and risk points of this operation into the system to form a personalized import file.The next time importing,it can quickly call historical data to predict possible problems and formulate response plans in advance.

The complexity of importing differential taxation goods requires the agency to not only be familiar with customs declaration procedures,but also master policies in multiple fields such as taxation,foreign exchange and quarantine.Zhongshen standardizes and modularizes each operation link.Customers only need to provide basic trade documents,and the subsequent document production,customs declaration,tax planning and inspection coordination are all handled by professional teams.This model greatly reduces the compliance risks of enterprises and shortens the overall clearance time.Data in 2026 shows that for Brazilian beef import businesses代理ed by Zhongshen,the average clearance time is shortened by 2.3 days compared with customers’ self-declaration,the tax cost is saved by 5%-8%,and the abnormal inspection rate is controlled within 3%.
