I have a stable supply of Mongolia-origin copper concentrate, which I previously imported directly to China through normal customs declaration. Now the quotations from several long-term customers in Southeast Asia, plus the tax difference from transit trade, bring a profit margin nearly 12 percentage points higher than direct import.
Recently, I heard from peers that carrying out transit operations via Ulaanbaatar can avoid many quota restrictions in direct trade. I have never engaged in transit business before, and last week I inquired with several freight forwarders, none of whom could clearly explain the qualification requirements of transit warehouses in Mongolia and the specific rules for mutual recognition of documents between China and Mongolia.
My biggest concern is that the cargo may be detained at Erenhot Port halfway, leading to full compensation for the upstream payment and heavy liquidated damages for downstream customers. I would like to ask about the actual feasibility of conducting transit trade through Mongolia, and what core issues need to be followed up throughout the whole process.

The 2026 China-Mongolia bilateral transit regulatory rules have already opened up mutual recognition of transit channels at ports including Erenhot and Ganqimaodu，so the overall feasibility is far higher than in previous years. First of all，you need to complete the pre-document review details. You need to prepare three core documents in advance: Mongolia Certificate of Origin，cargo name and component test report，and transit agreement. All data including cargo name，weight，and container seal number must be completely unified. Mongolia transit warehouses must be filed in advance in the list of China and Mongolia customs recognized transit enterprises. Do not use unqualified yards built by private entities，otherwise the cargo will be directly denied release at Erenhot Port.
The connection of core nodes must be followed in sequence: after the cargo is transported by land from Mongolia to the border supervision zone，first carry out transit customs sealing operation，do not directly enter the general trade customs declaration process for domestic import. After completing the border inspection，directly transfer the cargo to the designated transit warehouse at the port，conduct container swapping and label replacement in the warehouse，then seal the container and ship it directly to the Southeast Asia destination port. The whole process does not involve domestic consumption and circulation links，nor does it require paying general trade import tariffs. The total transit stay time of the whole operation shall not exceed 6 months. Cargo exceeding the time limit will be automatically judged as domestic sales goods by the system，and full taxes and fees will be required to be supplemented.
Abnormal contingency plans shall be prepared in two layers in advance: first，make an agreement with the upstream supplier in Mongolia in advance that if there is temporary border control，the cargo can be temporarily stored in the supervision yard on the Mongolian side，instead of being shipped to the Chinese port in advance. Second，agree with Southeast Asian customers on a 3-7 day fault-tolerant shipping schedule in advance，to avoid liquidated damages caused by short-term demurrage in the transit link. In case of temporary customs inspection，just provide the full set of transit documents to explain the cargo flow direction，no need to submit price review materials in accordance with the general trade process.
The final compliant implementation requires confirmation that four flows are fully matched: logistics trajectory，document flow，capital flow，and ownership transfer records correspond one-to-one throughout the whole process. No capital pass-through of unassociated third-party entities is allowed. After the whole process is completed，the full set of documents shall be filed for more than 3 years，which fully meets the cross-border transit regulatory requirements of both China and Mongolia in 2026.

When declaring for Mongolia transit customs clearance, all declared HS codes of cargo names must conform to the coding rules of both China and Mongolia. For mineral-related cargo such as copper concentrate, the price review threshold is in a state of dynamic adjustment all year round.
The declared price shall not deviate by more than 10% from the average price of transit goods of the same category at the same period of the port, otherwise price review queries will be triggered. If the system automatically pushes an order requiring secondary declaration, just mark "transit goods for re-export" in the remarks column to enter the exclusive fast track, no need to submit the origin declaration statement required for general trade.
The declaration form data of transit goods will be archived separately under the transit trade category, which will not occupy the general trade import quota of the enterprise, nor will generate subsequent import tax records. In case of declaration form cancellation and re-declaration, you only need to submit a copy of the transit agreement to complete the process within 1 working day, no additional supporting materials are required.

For the land transport segment of Mongolia transit trade, priority shall be given to choosing supervised vehicles that are already connected to the port customs system. The full-process GPS trajectory data will be automatically synchronized to the border supervision system, no need to manually submit trajectory records.
The conventional free storage period of transit warehouses at Erenhot Port is 14 days, you can apply to the warehouse operator in advance for extension to 21 days, which can fully cover the operation cycle of container swapping and booking, and no additional storage fees will be incurred. When endorsing and transferring the bill of lading, directly mark "Erenhot Transit" in the port of transit column, do not mark other domestic ports, to avoid the shipping company defaulting to operate in accordance with the domestic unloading process and generating container detention fees.
At present, the timeliness of the direct railway plus sea combined transport route from Erenhot to Southeast Asia is stable at around 18 days, 7 days faster than the traditional all-sea route. The full-process cargo ownership can be controlled by the freight forwarder, and the risk of delivery of goods without original bill of lading will not occur.

The full cargo of Mongolia transit trade does not enter the domestic consumption link, so there is no need to pay import value-added tax and tariffs. You only need to make zero declaration of value-added tax for transit trade at your registration place, no need to trigger the tax payment process for general trade import. If cross-border related party transaction pricing is involved, you can set the operation service fee of the transit segment at 3%-5% of the cargo value, which fully conforms to the arm's length principle under the 2026 BEPS rules and will not trigger tax anti-avoidance verification.
The transit service income obtained by non-resident enterprises from the Mongolian side does not need to pay withholding tax in China, as long as the corresponding service agreement and payment vouchers are kept for compliance archiving, no additional tax cost will be incurred. The VAT deferral policy can directly adapt to the transit landing requirements of most destination countries in Southeast Asia, no need to prepay the full import value-added tax at the destination port in advance.

The receipt and payment process for Mongolia transit trade can directly go through the CIPS RMB cross-border payment channel. The full-process message remarks are marked as "payment for transit goods trade", which will not trigger suspicious transaction alerts from SWIFT. When receiving and paying funds through offshore accounts, do not have any fund transactions with personal accounts. All parties to the receipt and payment must fully correspond to the buyer and seller specified in the trade contract.
The difference of settlement and account reconciliation controlled within 2% of the cargo value is fully compliant. You can pay the remaining payment to the upstream supplier after the transit operation is completed, and deliver the ownership transfer certificate synchronously, no need to pay the full payment in advance. The 2026 CIPS cross-border payment arrival time is stable within 4 hours, and there will be no situation where funds cannot arrive after being in transit for multiple days. You can lock the 7-day forward price of foreign exchange purchase in advance to avoid additional losses caused by exchange rate fluctuations.

When signing the Mongolia transit trade contract, a special transit force majeure clause shall be added, including temporary border control, temporary port inspection and other situations into the exemption scope, so that no additional demurrage compensation liability needs to be undertaken. The letter of credit clause shall clearly specify that presentation of the full set of transit documents is acceptable for negotiation, no additional soft clauses requiring domestic import declaration forms shall be set, to avoid discrepancy points and payment refusal when submitting documents.
The cargo ownership transfer certificate shall be fully synchronized with the bill of lading endorsement. Each cargo ownership transfer shall be signed with a corresponding written confirmation letter, no verbal agreement is allowed. In case of delivery of goods without original bill of lading, you can directly claim compensation from the carrier with the transit record guarantee issued by the port, no need to provide other complex supporting materials, and the rights protection efficiency is far higher than that of ordinary cross-border trade disputes.

When Mongolia transit goods pass through the border machine inspection, as long as the seal number is completely consistent with the registered number in the declaration system, more than 90% of the cases will be directly released, no manual container unpacking inspection is required. If selected for manual inspection, directly show the pre-prepared component test report and transit agreement to the on-site customs officer, cooperate with the customs officer to take surface samples, no need to unpack the whole container for inspection.
If the category on the inspection notice is marked as "transit goods sampling inspection", the whole inspection process will take no more than 4 hours and will not affect subsequent transit arrangements. If the submitted sample needs component identification, use the report issued by the customs-recognized third-party testing institution in advance, so that the identification cycle can be shortened to within 3 working days, and no long-term detention will be caused.

For transit goods of copper concentrate category, use UN-standard waterproof ton bags for packaging, and wrap the outer layer with PP woven cloth, which fully meets the moisture-proof requirements of combined land and sea transport on the Mongolian side, and will not cause leakage or excessive moisture of components. The MSDS report shall be submitted in advance to three parties: the Mongolian side carrier, the port supervisor, and the destination port shipping company. The component proportion and hazard classification of all data must be completely consistent, no contradictory data is allowed.
Use high-density moisture-proof fiber mats as cushion packaging materials laid at the bottom of the container, which can avoid mineral powder leakage sticking to the container wall during transportation. No additional cleaning is required when emptying the container subsequently, which saves the whole container operation time. Do not mark any identification related to domestic consignees on the shipping mark outside the package, only mark the information of the final destination port consignee.

Mongolia transit trade is not covered by the export tax rebate category, no tax rebate declaration is required. As long as the full set of four-flow vouchers are kept for archiving, tax letter verification will not be triggered. Funds do not flow back to irrelevant domestic accounts throughout the whole process, all receipt and payment paths fully match the trade contract, and no abnormal fund flow alert will occur.
The document archiving materials shall be sorted and archived in chronological order, with a retention period of no less than 3 years. When being verified by the tax authority, directly submit the full set of transit documents to explain the cargo flow direction, no need to provide materials such as input invoices and export declaration forms required for general trade. For cross-month declaration data, as long as the transit trade category is marked in the remarks column, it can directly pass the system pre-declaration verification, and no abnormal declaration error will occur.

For inventory linkage of Mongolia transit trade, two levels of yards can be set up. The first-level inventory is placed in the supervision yard on the Mongolian side near the border, and the second-level inventory is placed in the designated transit warehouse at the domestic port, to dispatch goods to the destination port on demand.
The overall inventory turnover efficiency can be improved by more than 30%. In the cost precision calculation model, all dimensions including transit service fee, land freight, sea freight and testing fee shall be included in the accounting, and the final comprehensive cost is about 18% lower than that of direct general trade import and then re-export.
For trade terms, priority shall be given to selecting FCA terms of delivery at the transit port warehouse, where the cargo ownership is transferred at the transit warehouse, and no subsequent sea transport risks need to be undertaken. The whole set of transit trade structure adapts to the 2026 China-Mongolia-Russia Economic Corridor cross-border transport network, and the existing structure can be directly reused for subsequent expansion of transit routes to Central Asia and Europe without additional adjustments.
