Full Accounting Process for Import Agency Companies: Practical Guide from Customs Valuation to Tax Refund

Full Accounting Processing Procedure for Import Agency Companies: Practical Operation from Customs Valuation to Tax Refund

As an agency company with 20 years of deep engagement at Shanghai Port,we have seen numerous clients suffer customs clearance delays due to non-standard accounting processing: a mechanical and electrical equipment importer paid an extra 120,000 RMB in tariffs after being placed under customs inspection for failing to verify the HS code in advance; a cosmetics company received a Notice of Refusal of Release directly from the commodity inspection authority for omitting brand information in the declaration.The accounting work of import agency companies is far from simple bookkeeping and tax filing,but a compliance management system running through the entire chain of customs declaration,logistics,foreign exchange and tax refund.

1.Customs Valuation: The First Compliance Threshold for Accounting Processing

In 2026,the customs valuation system has realized three-dimensional comparison of "documents + logistics + market price".To reduce tariff costs,enterprises need to complete three key tasks in the early stage of accounting processing:

• Accurate HS Code Classification: A customer’s imported stainless steel thermos cups were incorrectly classified under "kitchen utensils" (tariff heading 7324),which increased the tax rate from 8% to 15%.Zhongshitong provided classification basis for "daily sundries" (tariff heading 7615) and helped the customer recover 300,000 RMB in tax losses.The key lies in verifying the "material" (stainless steel falls under Chapter 76) and "purpose" (daily drinking),rather than judging solely by the product name.
• Consistency Between Declaration Elements and Actual Goods: The "brand" on the customs declaration form shall be completely consistent with that on the bill of lading and contract.A medical device company was identified as having "non-origin goods" by customs for incorrectly filling in "no brand",resulting in 27 days of port detention fees during the period of supplementary document submission.
• Prediction of Price Declaration Model: A new price comparison system for "cross-border e-commerce retail import" goods was launched in 2026.If the declared price is more than 10% lower than the system benchmark price,enterprises need to submit explanations for price rationality (such as certificate of origin,procurement contract,payment voucher).

2.Commodity Inspection Pre-review: Pre-risk Control Link for Accounting Processing

For categories requiring special quarantine such as animal and plant products and cosmetics,the "three pre-review" mechanism shall be embedded in accounting processing:

1.Quarantine Certificate Pre-review: A food company’s imported Vietnamese rice was intercepted by the quarantine department of Shanghai Port for failing to apply for the Entry Animal and Plant Quarantine Permit in advance,resulting in 680,000 RMB of demurrage charges for 200 tons of goods stranded at the port.Zhongshitong adopts the dual review mode of "agency inspection applicant + customs pre-classification specialist" to complete document pre-review 3 working days in advance.

2.Label Filing Verification: For imported cosmetics,Chinese label filing shall be completed before customs declaration.A daily chemical enterprise was required to rectify by the commodity inspection authority for omitting "sun protection factor" in the label,resulting in a 15-day delay in customs clearance for the entire batch of goods.

3.Special Supervision for Cross-border E-commerce: If the cross-border e-commerce bonded warehouse model is involved,it is necessary to verify the accounting consistency between "list verification and release" and "summary declaration",to avoid regulatory penalties caused by "under-declaration for multiple orders".

3.Import License: Hidden Compliance Cost for Accounting Processing

A new "dynamic license verification system" was launched in 2026.Enterprises shall reserve processing costs for three types of licenses in their accounting:

• 3C Certification List: Mechanical and electrical products shall complete CCC certification filing in advance.A furniture company had its declaration rejected directly by customs for failing to declare that "wooden furniture" requires 3C certification.
• Dual-use Item License: For imports involving rare earths and surveillance chemicals,a "statement of end use" shall be provided,and "license processing deposit" shall be listed separately in accounting processing.
• Endangered Species Certificate: For products such as ivory and red coral,"non-endangered" shall be indicated in the remarks column of the customs declaration form.A handicraft company faced a fine of 500,000 RMB plus goods seizure for incorrectly declaring endangered species.

4.2026 Import Agency Accounting Risk Warning: Three Hidden Traps

1.Demurrage Trap: A customer’s agency company failed to indicate the "demurrage allowed" clause when exchanging the bill of lading,resulting in a 45-day demurrage fee (800 RMB per day) due to delayed pick-up caused by document problems after the goods arrived at the port.It is recommended to clarify the "demurrage responsible party" clause in accounting processing.Zhongshitong can reduce demurrage risk by 60% through the dual agreement constraint of "shipping company + customs broker".

2.Hidden D/O Fee Irregularities: A freight forwarder charged additional "port storage fees" when exchanging documents.The upper limit of "original bill of lading exchange fee" shall be locked in advance in accounting processing (the standard for Shanghai Port is 200 RMB per shipment).Zhongshitong signs a "lump-sum document exchange agreement" with shipping companies,saving an average of 18% of document exchange costs for customers.

3.Foreign Exchange Settlement Loss: The RMB exchange rate fluctuation reached 3.2% in 2026.It is recommended that enterprises adopt a combined strategy of "batch foreign exchange settlement + forward foreign exchange settlement and sale".A medical device company suffered a foreign exchange loss of 280,000 RMB due to one-time settlement of foreign exchange.Zhongshitong successfully hedged the exchange rate risk through the mode of "30% advance payment + 70% settlement against documents".

5.Practical Case: Full Process Optimization of Accounting for a Chemical Import

Scenario: A chemical enterprise entrusted an agency company to import 200 tons of polycarbonate (PC).The originally declared HS code was "3907" (tax rate 10%),but after review by Zhongshitong,it was found that the correct HS code should be "3901" (tax rate 6%).Task: Ensure compliant accounting processing and reduce tariff costs.Actions: ① Re-verify the "non-origin country" clause of the certificate of origin; ② Retrieve the 2026 customs PC import price database; ③ Coordinate with the commodity inspection authority to issue a Classification Confirmation Letter.Result: The tariff was successfully reduced from 200,000 RMB to 120,000 RMB,the tax refund process was completed 5 working days in advance,and the financial cost was saved by 80,000 RMB.

6.Core Advantages of Zhongshitong Import Agency Accounting Services

As a core agency in Shanghai International Trade Center,we build accounting compliance barriers through three major capabilities:
