I work for a small and medium-sized precision mechanical parts manufacturer based in Nanjing. We have a batch of goods to export to Germany recently, and we heard that hiring a professional agency can save a lot of effort. However, my boss asked me to clarify first: does the agency fully cover the tax declaration service? We previously learned that customs declaration and export tax rebate are two separate procedures. Without relevant experience, we are worried that the agency may only handle customs declaration but ignore the tax rebate process, or make operational mistakes that cause delivery delays.
For example, the adjacent company had its goods detained by customs for a whole week last month due to incorrectly filled HS code on the customs declaration form, resulting in huge losses. Now we want to confirm: can export agencies in Nanjing help handle tax declaration related operations when goods are exported? What is the specific process? What common pitfalls should we avoid?

Whether Nanjing-based export agencies can handle tax declaration services should be judged based on 2026 customs regulatory requirements and the enterprise's actual situation. Taking the export of precision mechanical parts as an example，the agency can participate in the full closed loop of "export tax rebate + compliant declaration"，but must strictly follow the full-link operation specifications. The key process breakdown is as follows:
I. Pre-document Review Details: The agency shall complete the "three-document matching" verification before goods are warehoused，including commercial invoice (which must indicate the corresponding tax rate of the HS code，for example，Nanjing Customs added a new "certificate of origin" requirement for "auto parts" category in 2026)，packing list (whose gross weight and net weight must be completely consistent with that on the customs declaration form)，and customs declaration power of attorney (which must clearly define the scope of agency authority to avoid subsequent "ultra vires declaration"). Key verification shall be conducted on the "declaration elements" of the customs declaration form: for example，the "processing procedure" and "material composition" of mechanical parts must fully match the product specification. The 2026 customs document examination system has stricter validation on the "process description" field for "non-standard parts" products，and any error may trigger manual inspection.
II. Core Node Connection: The agency shall complete the "manifest pre-declaration" 48 hours before goods are dispatched，to ensure full consistency with the "shipping marks" on the bill of lading. If the goods involve wooden packaging，the IPPC fumigation certificate must be obtained in advance (the EU implemented "electronic traceability code" management for wooden packaging in 2026，and goods without valid codes will be directly returned by German customs). Meanwhile，the agency shall synchronously connect Nanjing Customs "Single Window" with the enterprise's ERP system，and complete the "secondary verification of declaration data" within 1 hour after submission，to avoid abnormal foreign exchange verification caused by decimal point errors in declared amount.
III. Abnormal Contingency Plan Design: In case of customs inspection，the agency shall send the "inspection notice" to the enterprise 24 hours in advance，and arrange dedicated personnel to cooperate on site. For the new "sampling inspection for bulk mechanical parts" launched by Nanjing Customs in 2026，the agency shall prepare product test reports in advance to avoid port detention caused by a test cycle longer than 3 days (the 2026 port detention fee standard at Nanjing Port is RMB 50 per container per day，linked to the declared weight on the customs declaration form). If the declared goods are classified as "sensitive goods"，the agency shall immediately activate the "classification dispute relief channel" to reduce tax rate risks through an application for advance classification ruling.
IV. Final Compliance Implementation: After goods leave the territory，the agency shall complete the export tax rebate declaration within 15 working days，with key verification on whether the "product name" and "specification & model" on the special VAT invoice are completely consistent with those on the export customs declaration form (the 2026 Nanjing tax authority only has a 37% approval rate for tax rebate applications of goods with multiple product names under one declaration form). Meanwhile，if the enterprise applies for the VAT deferral policy，the agency shall ensure seamless data connection between the offshore account and the Customs Electronic Port，to avoid suspended accounts at the tax bureau caused by delayed foreign exchange arrival.

Chief Customs Declaration Specialist: When Nanjing-based export agencies handle customs declaration, they shall focus on the "logical chain of declaration elements": for example, "stainless steel parts" shall be marked as "304/316L" in the "material" column of the customs declaration form.
If the agency only fills in "stainless steel", it will be regarded as a classification error. It is recommended that enterprises sign a "declaration error compensation agreement" with the agency, to clarify that the agency shall bear the port detention fee and losses caused by tax rebate delays for order returns / declaration deletion and re-submission due to the agency's fault.。

Senior Logistics Specialist: In 2026, Nanjing Port implemented "separate stowage transportation" for export dangerous goods. If the agency fails to confirm in advance that the UN number of the goods matches the means of transport, the goods may be rejected at German ports.
For example, in March 2026, a Nanjing machinery company had its goods detained at the Port of Hamburg, because the agency mistakenly booked the "UN3082 battery pack" as ordinary goods. It is recommended that the agency provide "transport condition appraisal report", and mark the dangerous goods class and packaging type clearly.。

Senior Tax Consultant: Under Nanjing's 2026 export tax rebate policy for enterprises, "R&D equipment" can apply for the superimposition of "Exemption, Credit and Refund" and "Instant Refund on Collection" policies, but the agency shall confirm the "fixed assets ledger" with the enterprise 6 months in advance.
If the agency fails to inform the relationship between "equipment depreciation period" and "export proportion", the enterprise may pay more value-added tax than required. It is recommended that the agency provide the "HS code matching table" and "VAT calculation model".。

Trade Compliance Specialist: In 2026, Nanjing Customs implemented "item-by-item verification for foreign exchange receipt over 5 million RMB" for offshore accounts. The agency shall ensure that the amount error between the foreign exchange settlement slip and the customs declaration form does not exceed 0.5%.
If the agency only provides SWIFT message screenshot without official bank stamp certificate, it may be judged as "abnormal foreign exchange receipt" by the State Administration of Foreign Exchange, leading to a 3-6 month delay of tax rebate.。

Foreign Trade Legal Specialist: The agency shall clearly specify the "intellectual property ownership" in the customs declaration power of attorney. In 2026, German customs has included "design patent infringement" into key inspection targets.
If the agency fails to verify the enterprise's EU trademark registration certificate, the goods may be detained at the Port of Hamburg. It is recommended that the agency add an "intellectual property compliance liability clause" in the contract, clarifying that the agency shall bear all losses caused by trademark related issues.。

On-site Inspection Specialist: Nanjing Customs launched a new "non-intrusive inspection" system in 2026. The agency shall prepare the "goods placement diagram" in advance, to ensure that key parts (such as part number, production date) are clearly visible.
If the agency does not arrange a dedicated inspection specialist to accompany the whole process, the inspector may make misjudgment due to irregular operation. It is recommended that the agency provide the "inspection flow chart" and "problem response script".。

Special Packaging Engineer: In 2026, the EU implemented the "anti-vibration packaging standard" for precision mechanical parts. The agency shall ensure that the goods packaging meets the ISTA 3A standard.
If the agency only uses ordinary cartons without providing the "cushioning material test report", the goods may be damaged during transportation. It is recommended that the agency provide a "packaging compliance letter of commitment", attached with packaging damage rate data for guarantee.。
