Practical Guide to Full-Process Compliant Operation and Risk Avoidance for Haicang Export Tax Refund Agency

Core Policy Changes for Haicang Export Tax Refund in 2026

In 2026,the General Administration of Customs and the State Taxation Administration jointly updated export tax refund supervision rules,with key adjustments made to certificate of origin review,HS code classification consistency,and declaration standards for cross-border e-commerce B2B export tax refunds.As a linked area of Xiamen Free Trade Zone,Haicang allows local enterprises to enjoy the preference of certificate of origin endorsement under RCEP member states.The tax refund review period for electromechanical and chemical products is shortened to 7 working days,but a new mandatory requirement for electronic document verification is added: all paper documents must be uploaded with corresponding electronic versions simultaneously,and electronic data must be completely consistent with paper content,otherwise the declaration will not be accepted.

Practical Adjustments to Certificate of Origin Endorsement

For Haicang enterprises exporting to RCEP member states,from 2026,they are required to submit certificates of origin endorsed by the China Council for the Promotion of International Trade,and information on the certificates must fully match that on customs declaration forms and commercial invoices.We once assisted a hardware tool enterprise whose tax refund application was rejected due to missing product model information on the certificate of origin.After verifying the full set of documents 3 days in advance,we completed corrections and resubmitted the tax refund declaration within 3 working days,avoiding a 5-working-day review delay.

Core Risk Points and Avoidance Solutions for Haicang Export Tax Refund

In 2026,the customs supervision model added the indicator of "data deviation rate between tax refund declaration and customs declaration".Enterprises with a deviation exceeding 5% will be listed as key inspection targets.There are three common pitfalls for Haicang foreign trade enterprises:

• Wrong HS code classification: It is required to refer to the 2026 edition of Customs Tariff.Electromechanical products need to provide additional filing certificates from the electromechanical administration,and chemical products need to be attached with MSDS reports.Wrong classification will lead to a 1-3 percentage point reduction in tax refund rate,resulting in direct loss of tax refund amount.
• Inconsistency between declaration elements and actual goods: Brand,model,material and specification must be filled in truthfully.For example,for exported stainless steel fasteners,it is necessary to clearly mark whether the material is 304 or 316,otherwise it will be judged as false declaration and face a fine of 10%-50% of the cargo value.
• Delayed foreign exchange verification: From 2026,tax refund declaration must be completed within 15 days after foreign exchange is received.For overdue declaration,an extension application and reasonable proof must be submitted,otherwise the tax refund policy cannot be enjoyed.

Review of Actual Haicang Export Tax Refund Cases

In November 2025,a plastic product enterprise in Haicang exported plastic turnover boxes to the EU.The customs declarer mistakenly classified the HS code as 39232900 (other plastic lids and containers),while the actual classification should be 39233000 (plastic packing boxes and containers),which led to the tax refund rate dropping from 13% to 9%,resulting in a direct tax refund loss of about 126,000 yuan.After we intervened,we assisted the enterprise to submit compliance certificates of product material and usage,completed re-declaration of HS code classification,passed customs review within 3 working days,and recovered the full amount of lost tax refund.This case proves that professional classification review is the core link of tax refund compliance.

Compliance Red Line Reminder

Three types of illegal operations are strictly prohibited in 2026: forging certificates of origin,falsely reporting export cargo quantity,and withholding funds after foreign exchange verification.Once investigated and punished by customs,enterprises will be listed as dishonest enterprises,their tax refund qualification will be suspended for 1-3 years,and they will face a fine of 10%-50% of the cargo value at the same time.Our risk control system will check these risks throughout the process to ensure enterprises operate in compliance and avoid unnecessary losses.
