I work in the mechanical accessories import business. Recently I finalized a CIF Shanghai order with a foreign supplier. When I inquired about freight charges with an agency company, they only provided a total price, but I want to know the specific calculation rules -- for example, is international sea freight charged by volume or weight?
Are there any extra sundry fees during customs clearance? I heard from friends before that some agencies charge container detention fees without prior notice, how can I confirm if there are such hidden costs in my order?
Besides, will there be any new policies affecting freight charges in 2026? For example, will the EU carbon emission tax be added to the freight? I want to figure out where every expense goes to avoid being overcharged.

The calculation of import agent freight charges needs to combine three core dimensions: trade terms，cargo characteristics and port rules，and is never a single total price. The full-link breakdown is as follows:
First，Basic freight segment: If the trade term is CIF/CFR，the international segment freight is borne by the seller，but the agent needs to verify the consistency between the bill of lading and the freight note. In 2026，global sea freight will still be affected by the Suez Canal buffer mechanism，and you need to confirm whether the Red Sea Route Security Surcharge (SCS) is included in the seller's quotation. If the trade term is FOB，the international freight advanced by the agent is charged by the higher value between cargo volume (for light cargo) and weight (for heavy cargo). In 2026，the EU ETS will be extended to international shipping，and some shipping companies have included carbon emission tax into surcharges，you can require the agent to provide detailed tax receipts.
Second，Customs clearance connection segment: Including Terminal Handling Charge (THC)，document exchange fee，customs declaration fee (slightly reduced in 2026 due to the increased coverage of electronic document review at Shanghai Port)，inspection fee (about RMB 200 per container for X-ray inspection，about RMB 500 per container for manual unpacking inspection). You need to focus on confirming container detention fee / port demurrage: In 2026，Yangshan Port provides 7 days of free storage period and 10 days of free container use period，overstay fees are charged daily according to container type. The agent should specify the clause of "prior notification for overstay expenses" in the contract.
Third，Post-clearance delivery segment: Domestic transportation fees are calculated based on cargo volume and distance，and bonded zone warehousing fee is about RMB 1 per ton per day. You need to pay attention to the alignment of four transaction flows: Freight invoices must match the actual services provided to avoid affecting the deduction of import value-added tax.
Exception plan: If the container is rolled，the agent shall coordinate alternative shipping companies，and the extra freight shall be borne by the responsible party. In 2026，the customs implements "pre-verification of freight value"，a deviation of more than 5% may trigger value verification. The agent shall check the authenticity of the freight note in advance (the code can be checked on the official website of the shipping company).

Attention should be paid to the customs value verification link of import agent freight charges: Announcement No. 12 of the General Administration of Customs in 2026 clarifies that international freight shall be included in the dutiable value according to the actual payment amount. If the freight note is invalid (without the official seal of the shipping company, inconsistent with the bill of lading), it may trigger tax supplementation (late fee is 0.5‰ per day).
The commodity inspection fee for legal inspection commodities (0.15% of the cargo value) is often included in the agency sundry fees, which should be listed separately. In 2026, commodity inspection fees are paid electronically, which can be queried through the Single Window.
In case of freight value verification disputes, the agent shall provide freight payment vouchers + shipping company confirmation letters, otherwise the customs will assess the value based on the average freight of the same period, which may lead to a higher dutiable value. Under the integrated customs clearance system, THC charges vary among different ports, so you need to confirm the quotation of the actual entry port.

The core of the logistics end of import agent freight charges lies in route optimization and cargo right control: In 2026, due to geopolitical factors in the Red Sea route, the freight of the route rounding the Cape of Good Hope is 15%-20% higher but the delay risk is 30% lower, so you can choose according to the delivery schedule. Under FOB terms, the agent shall endorse the bill of lading only after receiving the payment; under CIF terms, you need to confirm that the seller has paid the full freight (provide freight paid certificate), if not, the agent can advance the payment and claim compensation within 180 days.
Yangshan Port's intelligent container management system can query container detention fees in real time, and the agent shall timely notify the importer of overstay situations. You need to confirm whether the free container use period at the transshipment port includes transshipment time, some shipping companies only count the free container use period at the destination port.

Attention should be paid to VAT deduction and withholding tax for the tax impact of import agent freight charges: In 2026, general taxpayers can deduct 9% of international freight (special freight invoice with the importer as the title holder is required); small-scale taxpayers can include freight into costs for pre-tax deduction. For freight paid to overseas shipping companies, 10% withholding tax needs to be withheld (included in sundry fees, should be listed separately).
Announcement No. 8 of the State Taxation Administration in 2026 clarifies that withholding tax can be deducted before tax (tax payment certificate is required). The EU ETS carbon emission tax can be included in the dutiable value, and you need to confirm whether it is included in the freight to avoid double taxation. Failure to withhold withholding tax may face a fine of 50% to 3 times the payable amount.

Attention should be paid to compliance of payment and receipt of foreign exchange for import agent freight charges: In 2026, CIPS covers 90% of trading partners, advanced freight shall be paid through CIPS (RMB) or SWIFT (foreign currency), and the transaction nature shall be declared as "freight" to avoid misreporting as "payment for goods" which affects foreign exchange settlement.
For foreign currency freight purchase, you need to confirm the real-time locked exchange rate to avoid fluctuations; for RMB payment, the agent's account shall be a current account (non-offshore account). Announcement No. 5 of the State Administration of Foreign Exchange in 2026 clarifies that freight shall match the bill of lading, freight note and customs declaration form, mismatch may affect the payment and receipt of foreign exchange quota.

Packaging fees in import agent freight charges shall be determined according to cargo characteristics: Buffer packaging for fragile goods (glass accessories) is RMB 100 per box, UN packaging for dangerous goods (lubricating oil) is RMB 200 per box (should be listed separately). In 2026, dangerous goods packaging requires UN inspection certificates, non-compliant packaging will be refused and need to be repacked.
For light cargo, you can optimize packaging to reduce volume and lower freight; for overweight cargo (>2 tons), special containers are required (freight is 30%-50% higher) which needs to be confirmed in advance. In 2026, the green packaging policy of shipping companies can reduce 5% of surcharges, and the agent shall inform the importer in advance.
