# How to standardize the filling of supervision method code in transit trade customs declaration form to meet compliance requirements?

## Question

 I am a sales representative of a foreign trade company in Shanghai. A batch of transit trade I handled last month was detained in Hong Kong for 3 days due to incorrect filling of the supervision method code on the customs declaration form, which not only incurred nearly CNY 20,000 in port detention fees, but also triggered a customs early warning. I need to handle three batches of transit trade of different cargo types these days, namely chemicals, mechanical and electrical products and textiles, involving customs declaration supervision codes, receipt and payment declaration codes and customs statistics codes. I am very worried now that I will make filling errors again and cause problems. I would like to ask how to fill in various types of codes for transit trade under different scenarios? What details should I pay attention to to avoid repeating previous mistakes? 

## Answers
                            
### Answer 1 — Best Answer

First，complete the pre-document review details: first check the core documents according to the transit type (direct transit/indirect transit)，including purchase and sales contracts，ocean bills of lading，and manifest information，to confirm that the business nature fully matches the definition of transit trade，and synchronously verify the HS code corresponding to the cargo type to pave the way for subsequent statistics code matching.

The connection of core nodes must be accurately aligned: in the customs declaration link，**the supervision method code for direct transit is 0130，and for indirect transit is 0139**，which should be accurately filled in the "Supervision Method" column of the customs declaration form，and the upstream and downstream contracts of transit trade and copies of bills of lading should be uploaded synchronously，in the receipt and payment link，**the BOP reporting code for income is 102030，and for expenditure is 202030**，the corresponding customs declaration form number should be noted when declaring to ensure the consistency of documents，funds and codes.

Abnormal response plans must be clarified in advance: if a code filling error is found，you can directly apply for deletion and re-declaration before the customs declaration form is released，if it has been released，you need to submit the Application Form for Amendment/Cancellation of Customs Declaration Form within 3 working days，attach supporting documents proving the business nature (such as original contracts，bills of lading)，and apply for code correction to avoid customs early warnings from escalating to penalties.

To achieve final compliance implementation，all end-to-end documents must be retained: keep all materials such as customs declaration forms，receipt and payment vouchers，purchase and sales contracts，and bills of lading for at least 5 years，and conduct regular internal self-inspections to ensure that codes always match the business nature and avoid compliance risks.

### Answer 2

Filling of transit trade customs declaration codes must strictly follow customs supervision logic. First, distinguish the core differences between direct and indirect transit: direct transit means goods do not enter the territory and are directly transshipped overseas, with the corresponding code 0130; indirect transit means goods are re-exported after entering the territory, with the corresponding code 0139. When filling, simultaneously note the transshipment port and upstream and downstream customer information in the "Remarks" column of the customs declaration form to avoid customs document review doubts caused by incomplete information.

If there are multiple cargo types mixed for transit, fill in the statistics codes separately according to the HS code corresponding to each cargo type, do not declare jointly, otherwise it will trigger customs statistics early warning. In addition, after filling the code, verify it through the customs pre-declaration system. If the system prompts that the code does not match the cargo type, immediately check the HS code and transit type, and do not force declaration under any circumstances.

### Answer 3

Code matching in the logistics link of transit trade must be synchronized with the transportation route. First, confirm the supervision requirements of the transshipment port: if the transshipment port is a free trade port such as Hong Kong, Singapore, etc., note the corresponding code for "transit goods" in the logistics manifest to avoid being misjudged as imported goods by local customs and incurring port detention fees. If sea transshipment is adopted, mark "FOR TRANSIT" on the bill of lading, and fill in the corresponding transit transportation code when declaring the manifest to ensure document consistency during ownership transfer.

In addition, if goods need temporary storage at the transshipment port, submit a transit storage application to the transshipment port customs in advance to obtain the corresponding storage filing code, to avoid goods being temporarily detained. If encountering abnormal situations such as rollover, port change, etc., update the transit code in the logistics manifest in time to ensure consistency with customs declaration form and receipt and payment codes.

### Answer 4

Tax-related codes for transit trade must be synchronized with cross-border tax planning. First, clarify that transit trade is not import or export, and there is no need to pay import tariffs and value-added tax, so fill in the "transit trade tax exemption declaration code" when filing tax returns to avoid paying taxes by mistake. If transit trade involves cross-border related party transactions, fill in the corresponding related party transaction code when filing transfer pricing records to ensure pricing complies with the arm's length principle, and avoid triggering BEPS (Base Erosion and Profit Shifting) investigations.

In addition, if transit trade involves receipt and payment in different currencies, note the exchange rate conversion code when filing tax returns to ensure accurate calculation of the tax base. If there is profit remittance from transit trade, fill in the non-resident enterprise withholding tax exemption code, and provide end-to-end document certification of transit trade to avoid being withheld withholding tax.

### Answer 5

The selection of transit trade receipt and payment codes must comply with BOP statistics declaration specifications. First, distinguish the different codes for transit trade income and expenditure: income corresponds to 102030, expenditure corresponds to 202030. When declaring, note details such as transit goods name, quantity, transshipment port in the "Transaction Remarks" column to ensure bank review is passed.

If cross-border RMB payment (CIPS system) is adopted, fill in the corresponding transit trade code in the "Transaction Code" field of the payment message to avoid payment being returned due to code mismatch. In addition, if there is a time difference between receipt and payment in transit trade, report in advance in the foreign exchange monitoring system and fill in the time difference filing code to avoid being listed as a foreign exchange abnormal early warning target. If involving receipt and payment through offshore accounts, simultaneously note the transit trade code in the transaction details of the offshore account to ensure account fund flow compliance.

### Answer 6

Filling of transit trade codes must be synchronized with contract terms. First, clearly mark the words "transit trade" in the purchase and sales contract, and note the corresponding customs declaration and receipt and payment codes in the contract annex to avoid legal disputes caused by mismatch between contract terms and codes.

If involving letter of credit settlement, note the corresponding transit trade code in the "Additional Clauses" of the letter of credit to ensure document consistency when the bank reviews the letter of credit. In addition, if there is ownership transfer in transit trade, note the transit trade code when endorsing the bill of lading to avoid ownership disputes caused by mismatch between ownership certificate and code.

If transit trade is terminated due to force majeure, note the code change in the contract termination agreement to avoid subsequent compliance risks. At the same time, all code-related contracts and documents must be retained for at least 5 years as evidence in legal disputes.

### Answer 7

Transit trade is not within the scope of export tax rebates, so fill in the "non-export tax rebate business code" when filing tax returns to avoid audit risks caused by mistakenly applying for export tax rebates. First, distinguish the core differences between transit trade and general trade: transit trade goods do not actually enter or exit the territory (direct transit), so there is no need to file export tax rebate declaration, fill in the corresponding tax exemption code when declaring value-added tax, and do not check the export tax rebate column.

In addition, if there is capital return in transit trade, note the transit trade code in the capital flow details to avoid being misjudged as export tax rebate fraud by tax authorities. If involving transit trade document filing, store customs declaration forms, receipt and payment vouchers, purchase and sales contracts and other materials classified by transit trade codes to facilitate retrieval and verification during tax audits. At the same time, conduct regular internal tax rebate audits to investigate tax rebate risks caused by code filling errors.
