What are the core compliance nodes that must be strictly controlled in the full process of resin import customs brokerage?
or complex compliance issues.
clearance and fund security.
I am the procurement supervisor of a manufacturing enterprise in Zhejiang that produces wind turbine blade composite materials. Last week, we finalized an order of 12 tons of bisphenol A epoxy resin with a Taiwanese supplier, which will be shipped from Kaohsiung Port to Shanghai Yangshan Port by the end of next month. This is the first time we import chemical raw materials independently.
We used to purchase goods from traders before, and now we switch to self-operated import to cut 15% of procurement costs, but I am completely unfamiliar with the whole process. I heard that some resins are classified as hazardous chemicals? Will they be subject to key inspection during customs declaration?
A peer company was detained for 12 days when importing modified plastic pellets due to wrong HS code declaration, which cost more than 30,000 yuan in container detention fees alone and delayed the production line schedule. I am very anxious now, afraid that any omission on my part will lead to customs detention and port delay, affecting the delivery of 3 large customer orders next month. I would like to ask how resin import customs brokerage services work, and whether they can help me avoid these risks accurately?

First is the details of pre-document review: You need to submit the full set of documents 3-5 working days in advance，with focus on checking HS code classification (resin shall be classified accurately according to composition，molecular structure and application. In 2026，the verification accuracy of customs for chemical product code classification has been improved to identify composition difference of 0.5%. If epoxy resin is incorrectly classified into the code for ordinary plastics，it will trigger price review disputes or customs detention)，MSDS report (confirm whether it is a hazardous chemical，and hazardous characteristic identification report issued by an authoritative institution shall be supplemented if it is classified as hazardous chemical)，certificate of origin (to enjoy ECFA tariff reduction，you need to ensure that the goods description and quantity on the certificate are completely consistent with those on the bill of lading and invoice)，and check the matching between bill of lading endorsement and customs filing qualification at the same time.
Core node connection: Complete the pre-entry of customs declaration form and synchronize it to the Customs Single Window 24 hours before the goods arrive at the port. When exchanging documents with the port，you need to reserve compliant hazardous warehouse space 7 working days in advance for hazardous chemicals to avoid port detention caused by insufficient space，complete tax payment through the electronic tax payment system immediately after the customs declaration is approved，to ensure that the vouchers are synchronized to the customs in real time and shorten the customs clearance time.
Pre-formulation of exception response plans: Predict three types of high-frequency exceptions in advance: First，customs price review objection，prepare supporting materials such as procurement contracts，foreign exchange payment vouchers and supplier cost details in advance，Second，inconsistency in on-site inspection，arrange exclusive specialist to accompany the whole process，and submit supplementary explanations and test reports immediately if there is deviation in goods description，Third，non-compliant hazardous chemical labels，prepare compliant label stickers in advance for on-site rectification.
Final compliance implementation: Sort out and file the full set of customs clearance documents within 3 working days after the goods are released，including customs declaration forms，tax payment vouchers，certificates of origin，etc。to facilitate subsequent VAT deduction and customs retrospective inspection，and ensure that the whole process meets the 2026 regulatory requirements for chemical import.

HS code classification is the core compliance link in resin import customs declaration. In 2026, the verification accuracy of customs for chemical product code classification has been improved to identify composition difference of 0.5%. If an enterprise incorrectly classifies epoxy resin into the code for ordinary plastics (39073000) instead of the code for chemical products (38249999), it will trigger customs price review disputes, and the enterprise needs to submit supporting materials such as composition test reports and procurement contracts within 3 working days.
If the materials cannot be supplemented within the time limit, the enterprise will be listed as a key monitoring enterprise by the customs, and the customs clearance time for subsequent imported goods will be extended by more than 50%. In addition, the "goods use" column in the customs declaration form shall be filled accurately as "used for production of wind turbine blade composite materials" instead of the general "for industrial use", otherwise it will directly affect the approval pass rate of ECFA certificate of origin tariff reduction.

The logistics route for resin import shall be selected accurately according to the properties of the goods. For hazardous chemical epoxy resin, priority shall be given to direct routes to Shanghai Yangshan Port to avoid container rollover caused by insufficient hazardous chemical storage space at transit ports.
In 2026, reservation for hazardous chemical berths at Yangshan Port requires submission of materials such as MSDS report and hazardous characteristic identification report 7 working days in advance, and reservation will not be accepted if overdue. After the goods arrive at the port, the free storage period is 48 hours, and the free container use period is 7 days.
If you need to extend the free container use period, you need to submit a written application to the shipping company within 3 working days after the goods arrive at the port. Overdue application will incur a container detention fee of 1200 yuan per container per day, and the shipping company has the right to directly auction the goods to offset the cost.

In 2026, enterprises can optimize capital flow through the VAT deferment policy for resin import. Enterprises need to apply for the "VAT deferment payment" qualification from the customs at the place of registration, and submit materials such as import contracts, business licenses, and tax payment certificates for the past 6 months.
After passing the review, the import VAT can be paid within 120 days after the goods are released, without one-off payment during customs clearance. Calculated based on the current VAT rate of 13%, the capital occupation cost saved for 12 tons of epoxy resin is about 87,000 yuan.
In addition, epoxy resin imported from Taiwan enjoys ECFA zero tariff treatment. You need to ensure that the "no further processing certificate" of the certificate of origin is issued by a Taiwanese notary institution, and the value-added proportion of the goods in Taiwan is not less than 40%, otherwise a tariff of 5.5% shall be paid, increasing the procurement cost by about 32,000 yuan.

The payment and receipt of foreign exchange for resin import shall comply with the 2026 cross-border payment regulatory requirements. If SWIFT message payment is adopted, the message shall clearly indicate "epoxy resin import payment", and submit materials such as customs declaration form, procurement contract and commercial invoice to the opening bank at the same time, to avoid being listed as suspicious transaction due to inconsistent payment and receipt purpose, which affects the subsequent cross-border payment authority.
If CIPS RMB cross-border payment is adopted, you can enjoy a 0.15% exchange rate discount given by the bank, and there is no need to go through foreign exchange verification procedures. The fund arrival time can be shortened to within 24 hours, saving about 2-3 days of arrival time compared with SWIFT payment.

When resin import is subject to on-site customs inspection, core materials such as composition test report, MSDS report and hazardous characteristic identification report shall be prepared in advance. For hazardous chemicals, ensure that the UN marking and hazard description on the goods packaging are completely consistent with the content of the report.
If image abnormality occurs during machine inspection, the customs will arrange unpacking inspection. At this time, you need to assist the customs to collect representative samples to avoid deviation in test results caused by improper sample collection, which delays customs clearance.
If the goods are found to be inconsistent with the documents after inspection, supplementary explanations and supporting materials shall be submitted within 2 working days. If they cannot be provided, a fine of 5%-10% of the goods value will be imposed, and the goods will be temporarily detained until the rectification is completed.

Epoxy resin is a moisture-sensitive chemical. In 2026, the customs has further improved the inspection requirements for packaging compliance of imported chemicals. Galvanized iron drums with moisture-proof and sealing functions shall be used, the drum cover shall be equipped with leak-proof rubber gaskets, the weight of each drum shall not exceed 200 kg, and information such as composition, net weight, and UN marking (for hazardous chemicals) shall be clearly marked on the packaging.
The interior of the container shall be paved with moisture-proof film with a thickness of no less than 0.2mm, and buffer foam blocks shall be added between each drum to avoid leakage caused by collision during transportation. In addition, the MSDS report shall include transportation precautions, leakage emergency treatment and other contents, and shall be issued by an internationally recognized third-party institution, otherwise the goods will be refused entry.

The supply chain planning for resin import shall be closely combined with production schedule and logistics time efficiency. In 2026, the average customs clearance time for ordinary chemical products at Shanghai Yangshan Port is 3-5 working days, and an additional 2-3 working days of inspection time is required for hazardous chemicals. Therefore, suppliers shall be arranged to deliver goods 15-20 days in advance to avoid affecting the production line schedule due to logistics delay.
In addition, the mode of "batch import + bonded warehousing" can be adopted to store imported epoxy resin in the Yangshan Port bonded area, and declare for import in batches according to production demand, which can enjoy the preferential rate of bonded warehousing, and flexibly adjust the import volume to avoid capital occupation caused by inventory backlog. At the same time, a monthly compliance review mechanism shall be established with the customs brokerage to continuously optimize the customs declaration process and cost control scheme.
