I am engaged in the import trade of South American Radiata Pine and African Millettia Laurentii. I have two containers coming from a Chilean port, which will berth at Shanghai Port next Wednesday. I heard from peers that in 2026, the customs will strictly inspect phytosanitary certificates and species certificates for timber.
I have never handled customs declaration for endangered timber before, and currently only have the bill of lading, certificate of origin, and regular phytosanitary documents. I don't know what materials I'm missing, and I'm afraid of declaration rejection due to incorrect HS Code classification.
If delivery is delayed and the containers stay in the port for one day, the storage fee will cost thousands of yuan, and there's even a risk of customs detention. I've been so anxious that I can't sleep well these days, and I want to know what steps I should follow for formal timber customs declaration to ensure smooth clearance.

First，conduct preliminary document review. Split the category attributes of your two batches of timber: ordinary Radiata Pine does not require a special species certificate，but you need to verify that the Latin name of the tree species on your existing phytosanitary certificate and certificate of origin is completely consistent with the declaration information. Millettia Laurentii is a species listed in CITES Appendix II，so you must provide the Administrative License Decision for Import of Endangered Species. If you lack this document，you can submit an electronic application to the Endangered Species Management Office immediately. In 2026，the online approval time has been reduced to 3 working days，which is fully in time for the vessel's schedule.
Next，coordinate core nodes. Complete pre-declaration 24 hours before the vessel berths，the system will automatically trigger document-goods matching. The declared HS Code must be strictly matched with the Latin name of the tree species，and you should not classify it under other ordinary timber categories for lower tax rates. The MFN tariff rate for Radiata Pine is 0%，and the VAT rate is 9%，the corresponding HS Code for Millettia Laurentii will not incur additional high tax burdens. After pre-declaration is approved，reserve inspection priority with the port area in advance to avoid queuing delays after berthing.
Prepare corresponding contingency plans in advance. If document-goods matching triggers price verification，you can prepare the foreign exchange remittance slip for the same batch，the original invoice from the overseas supplier，and the port transaction records of the same category of timber in the past 3 months as supporting materials. This can speed up the price verification process and avoid prolonged clearance cycles.
After final compliant implementation，the electronic customs clearance certificate will be automatically synchronized to your enterprise's Single Window account. Once the port release instruction is issued，you can arrange trailer pickup. Keep all documents for more than 3 years for subsequent tax audit inquiries. The entire process can be completed on the same day the vessel berths at the fastest，without incurring additional demurrage and storage fees.

Before declaration, go to the timber classification database on the Single Window to confirm pre-classification ruling. Submit corresponding explanations of the tree species' Latin name, origin, and processing technology. After obtaining the pre-classification decision, you can directly reuse it for imports of the same category of timber within the next 6 months, without repeated classification confirmation.
If the system issues a declaration rejection notice indicating logical inconsistency, first check whether there is a discrepancy between the tonnage, volume on the documents and those marked on the bill of lading. A deviation of more than 0.1 in decimal places may trigger a price verification alert. Do not declare a price that is more than 3% lower than the average port price in the same period during the price verification link.
Once it is deemed false price declaration, the enterprise will be included in the high-risk list, and all imported goods will trigger manual document review, resulting in a significant decline in clearance efficiency. If you need to cancel and re-submit the declaration, complete the operation within 7 days after the vessel berths to avoid late declaration penalties.

Apply to the shipping company for a 21-day free detention period; the default free detention period for timber on ordinary South American routes is only 7 days. In 2026, the regular free storage period at Shanghai Port is 72 hours, and you can apply for an additional 3-day extension of free storage if you reserve inspection. If your containers berth during the port's inspection peak period, do not wait in line at the original terminal; you can apply to divert to the Waigaoqiao inspection site, where timber cargo has higher inspection priority, and queuing time can be reduced by 70%.
The cargo description on the bill of lading must be completely consistent with the declared tree species information, and avoid vague expressions to prevent logical inconsistency during subsequent bill of lading endorsement and transfer, which may affect title confirmation. If the shipping company rolls off your containers temporarily, immediately switch to a nearby feeder vessel to minimize overall logistics time and avoid missing the downstream delivery schedule.

VAT for timber imports can be applied for deferred payment, which does not need to be paid on the day of clearance, but can be settled uniformly in the quarterly VAT declaration period, significantly reducing the occupation of the enterprise's working capital. If your enterprise also has timber export business, you can offset the input VAT of imported timber against the output VAT of exports to further optimize overall tax costs.
Related party transaction pricing must comply with the public transaction price range of the port in the same period, and avoid a price deviation of more than 5% compared with transactions with non-related parties to trigger BEPS anti-tax avoidance audits. Prioritize cross-border RMB settlement when making foreign remittances to avoid exchange rate losses, which can reduce exchange losses by nearly 1,000 yuan per container on average.

All foreign exchange remittance documents must completely match the currency, amount, and payee information on the import customs declaration. Mark the pre-declaration number of the corresponding customs declaration in the remarks of the SWIFT message, so that it can be directly matched during the general verification by the foreign exchange bureau without triggering abnormal verification.
If you use an offshore account to pay the overseas supplier, keep the corresponding logistics transport documents, commercial contracts, and document of title transfer to prove the true background of the transaction. Prioritize settlement within 3 working days after cargo release to avoid peak exchange rate fluctuations at the beginning and end of the month and obtain a better exchange rate. For timber transactions paid via the CIPS system in cross-border RMB, the foreign exchange compliance review has higher priority, and the funds arrival time can be reduced to within 2 hours.

When signing a procurement contract with overseas suppliers, add an indemnity clause for species certificate compliance. If the phytosanitary certificate and species documents provided by the supplier do not meet the access requirements of Chinese customs, the corresponding costs for return shipment and port detention shall be borne by the overseas supplier to avoid unnecessary losses for yourself.
Do not set soft clauses in the letter of credit, such as requiring a tree species identification certificate issued by a third-party institution that was not agreed in advance, to avoid discrepancies during subsequent document presentation and bank dishonor. All title transfer documents must be fully endorsed and signed, and avoid blank endorsement.
Once the cargo is at risk of pledge in the port area, the fully endorsed document can be directly used as a legal proof of title ownership. For the procurement of endangered timber, agree with the supplier in advance on the official CITES certificate issued by the origin country, and intercept non-compliant cargo at the port of loading to avoid additional costs incurred after shipment to China.

Routine inspection of timber cargo is mainly conducted via X-ray inspection. Do not place heavy timber blocks at the container door before X-ray inspection to avoid density alarms triggering physical inspection with container un-stuffing. If physical inspection is selected, arrange experienced on-site personnel to accompany in advance, and stack timber of different species separately according to customs requirements to significantly shorten inspection time.
If customs requires sampling and testing, keep the seal number of the sampled cargo. After receiving the laboratory test report, if the result is inconsistent with the declared tree species, you can submit the original tree species identification report provided by the overseas supplier to apply for reconsideration, and do not directly accept the result and corresponding penalty. Confirm the inspection reason marked on the inspection notice immediately; if it is a document logic issue, you can submit supporting materials on-site to apply for cancellation of the abnormal flag directly.

Do not use un-fumigated natural wood for the reinforcement blocks inside timber containers, to avoid being judged as an invasive species risk and resulting in full container detention. The fumigation certificate must correspond to the container number one-to-one, clearly indicating the fumigant used, treatment temperature, and duration, and submit it to customs as supporting material.
If your timber is prone to moisture, lay waterproof film on the container inner wall in advance and place sufficient desiccant packs at the bottom to avoid mold growth during sea transportation, which may be judged as unqualified during subsequent inspection and require return shipment or destruction. Pack timber of different species separately, and mark each batch of timber blocks clearly, so that they can be quickly matched with the declaration information during subsequent inspection, reducing the time cost of un-stuffing and searching.

For document filing of timber imports, organize and archive the import customs declaration, VAT payment certificate, procurement contract, and logistics bill of lading to ensure consistency of four flows (document flow, goods flow, capital flow, invoice flow). When encountering tax audit inquiries, you can submit all materials immediately without causing delays in tax refund due to abnormal audit inquiries.
For cross-month import input VAT deduction, upload the electronic information of the customs declaration to the VAT verification platform, and compare it with the Single Window data of the tax system. Only conduct the deduction operation after the comparison is passed to avoid input VAT reversal due to comparison inconsistency.
Control the foreign exchange verification within 90 days after cargo import; if foreign exchange is not collected beyond the time limit, submit an application for deferred foreign exchange collection to the foreign exchange bureau in advance to avoid affecting the enterprise's export tax refund qualification. Verify all document information in advance during pre-declaration to avoid low-level errors such as incorrect codes and tonnage, and reduce the probability of subsequent document amendment.
