What core elements should be included when compiling a proxy import product series list?
or complex compliance issues.
clearance and fund security.
I am the person in charge of an import trading company that has been established for half a year. I recently received a proxy import business involving two categories: smart watches and food-grade preservatives. This is the first time I have compiled a product series list. I heard that peers were subjected to customs valuation detention for three days due to vague list descriptions, resulting in nearly 10,000 yuan in container detention fees, and I am very anxious.
The goods will arrive at the port next week, and I still don’t even know what content should be included in the list—for example, whether to subdivide models, how detailed the specification parameters should be, and whether the classification standards should refer to HS codes. I am more worried about making mistakes leading to customs detention or fines, and I am eager to find professional guidance to solve this problem.

When compiling a proxy import product series list，it is necessary to start from customs declaration compliance and prioritize matching the elements of pre-submitted documents. First，ensure that the HS code of each product is accurate. In 2026，the customs will launch the "Code Intelligent Verification System". If the code does not match the actual goods，the system will automatically intercept and push for manual examination. Second，specification parameters need to be refined to the smallest unit. For example，smart watches should indicate the screen size，battery capacity and operating system version，while chemical raw materials should be marked with CAS number，purity and packaging specifications (25kg/drum).
Regarding core node connection，the list classification must fully correspond to the "commodity name" and "specification model" fields on the customs declaration form，avoiding vague expressions such as "a batch of electronic products". At the same time，the internal enterprise ledger should be updated synchronously to ensure consistency with the customs declaration list and prevent data contradictions in subsequent tax investigations.
Abnormal response plans need to be prepared in advance: if the list is returned by the customs after submission，the missing elements (such as product manuals and third-party test reports) should be supplemented within 24 hours，if there is a valuation dispute，procurement contracts，invoices and other vouchers should be immediately retrieved to prove the reasonableness of the price.
For final compliance implementation，reference should be made to the 2026 *Customs Import and Export Goods Standard Declaration Catalogue*. Special attention should be paid to food-grade chemical raw materials needing to be marked as "for food contact" or "not for food contact"，and electronic products should indicate whether they contain lithium batteries and the battery capacity. In addition，the list must be stamped with the enterprise's official seal and signed by the handler to ensure legal validity and avoid liability disputes.

Matching the HS code in the product series list is the core of customs declaration. In 2026, the customs' "Code Intelligent Verification System" will automatically intercept lists with incorrect codes.
For example, misclassifying a smart watch with a lithium battery as an ordinary watch (HS 9102) instead of a smart wearable device (HS 8517) will lead to tax rate differences and inconsistent supervision conditions, causing customs detention. It is recommended to verify the code through the official website of the General Administration of Customs when compiling, and then confirm the accuracy based on functions, materials and uses.

The classification of the product series list needs to consider actual logistics needs. Chemical raw materials and electronic products should be listed separately, because chemical raw materials may involve dangerous goods transportation qualifications, and lithium batteries in electronic products are aviation restricted items.
In 2026, international logistics has stricter requirements for dangerous goods packaging. The list must clearly mark the UN number and packaging category, and electronic products must indicate the lithium battery energy (Wh). In addition, the packaging specifications must be consistent with the actual situation to avoid billing errors or slot arrangement issues.

The description of the product series list directly affects tax accounting. In 2026, the VAT deferral policy will be extended to more categories. The list must clearly indicate the composition of the dutiable price and whether it meets the deferral conditions.
For example, food-grade chemical raw materials are imported materials under processing trade, and the manual number needs to be marked to apply for deferral. At the same time, the commodity name must be consistent with the VAT invoice to avoid the inability to deduct input tax.

The compliance of the product series list is related to foreign exchange receipts and payments. In 2026, the CIPS system has strict requirements for commodity descriptions in cross-border payments. The list name must be consistent with the SWIFT message.
For example, if the list says "food-grade preservatives" but the message says "chemical raw materials", the foreign exchange receipts and payments will be intercepted by the bank. It is recommended to refer to the *Incoterms 2024* to standardize descriptions and ensure consistency with payment documents.

The product series list must have legal validity to avoid disputes. Vague expressions such as "a batch of electronic products" will lead to subsequent liability issues. In 2026, the customs has increased its intellectual property protection efforts.
If the goods involve well-known brand trademarks, the list must be attached with a copy of the authorization letter to avoid customs detention due to infringement. In addition, the list must be used as an attachment to the agency contract to clarify the division of responsibilities between both parties.

The details of the product series list affect the on-site inspection results. In 2026, customs inspections will check the goods against the list parameters. For example, if the list says the smart watch has a 1.3-inch screen but the actual size is 1.5 inches, the inspection will fail.
It is recommended that the list include information such as appearance features, core parameters and packaging details to facilitate rapid verification by inspectors. At the same time, the storage location of the goods (container number, slot number) must be indicated to facilitate positioning.

The classification of the product series list needs to be combined with supply chain planning. In 2026, the import supply chain emphasizes inventory linkage. The list classification should be consistent with the enterprise's inventory system.
For example, electronic products are divided into subcategories such as smart watches and Bluetooth headsets, and chemical raw materials are divided into food-grade and industrial-grade subcategories to facilitate subsequent inventory counting and data analysis. In addition, the update frequency needs to be synchronized with market changes. Electronic products should be updated once every quarter, and chemical raw materials should be updated once every six months to ensure timeliness.
