Tianjin Raw Material Import Agency Full Process Guide

Tianjin Raw Material Import Agency: A Practical Guide from Compliance Access to Efficient Customs Clearance

Tianjin,as an important port city in northern China,is a core hub for the import of bulk commodities such as crude oil,minerals,and chemical raw materials.However,links involved in raw material import,including customs price verification,pre-commodity inspection,and special supervision,are highly professional; any slight negligence may lead to port detention,tax supplementation,or even return of goods.I once encountered a case: a machinery processing plant imported a batch of German steel.Due to an error in HS code classification (misclassifying "cold rolled steel plate" as "hot rolled"),it was subject to supplementary tax of 120000 yuan during customs inspection at Tianjin Port,delaying the production cycle by 3 weeks.

As an agency with 20 years of deep cultivation in foreign trade,Zhongshitong relies on resources from its Shanghai headquarters to achieve seamless connection of "off-site declaration + local coordination" at Tianjin Port.The following analyzes the compliance points and practical skills of Tianjin raw material import from 4 core links.

I.Customs Price Verification: 3 Key Actions to Avoid "Price Disputes"

Tianjin Customs has tightened its price verification standards for imported raw materials,and added a "historical transaction data verification" mechanism in 2026.Enterprises are often put under key control due to "declared prices that differ significantly from similar goods in the same period".

• Accurate HS Code Classification: Raw material products must strictly correspond to the Harmonized Commodity Description and Coding System.For example,"unnamed plastic raw materials" need to clarify elements such as "whether plasticizers are included" and "processing technology".Zhongshitong recommends using the "Customs Commodity Pre-classification System" for initial screening in advance to avoid errors in manual judgment.
• Price Declaration Benchmark Anchoring: Tianjin Customs will refer to EXW/FOB prices of imports in the same period and international bulk commodity indices (such as CRU,Platts).In Manager Ma’s case,since the factory price certificate of the German factory was not provided and only FOB was used for direct declaration,it was judged as "artificially high price".
• Pre-judgment of Special Supervision Conditions: For sensitive categories such as chemicals and minerals,it is necessary to check in advance whether anti-dumping duties are involved (for example,the anti-dumping duty rate on nickel ore for the EU remains at 8.1% in 2026) to avoid subsequent tax supplementation due to omissions in declaration.

II.Pre-Commodity Inspection: Pre-rectification of 3 "Must-Avoid Pitfall" Links

Tianjin Commodity Inspection Bureau has more detailed inspection standards for raw material imports than other ports,especially for categories involving "animal and plant origins" and "dangerous chemicals".

Special attention needs to be paid: The inspection rate of "mixed raw materials" at Tianjin Port has been increased to 18% (2026 new regulation).If the "main component proportion" is not clearly stated in the declaration,it may trigger on-site inspection.A chemical enterprise once declared "mixed resin" but did not mark the proportion of main components.During inspection,it was found to contain 15% of prohibited additives,leading to the return of the entire batch of goods.

III.Animal and Plant Quarantine and Special Supervision: Interpretation of 2026 Latest Policies

If the raw materials involve animal and plant-derived components (such as fur,bone meal,grain),they must strictly comply with the "Law of the People’s Republic of China on the Entry and Exit Animal and Plant Quarantine".Tianjin Customs implements a "72-hour rapid release" policy for "meat raw materials",but the premise is that the following must be provided:

• Official quarantine certificate from the exporting country (must have a "non-epidemic area" statement)
• Disinfection certificate for the means of transport (fumigation certificate is required for sea containers)
• "Transport trajectory records" for 30 days before import (to prevent pollution during transit)

Last year,a client imported "leather scraps" and failed to provide a "non-pathogen after processing" certificate.It was detained at Tianjin Port for 7 days and finally destroyed due to inability to supplement the documents.The core lesson of such cases is: Animal and plant quarantine certificates must fully match the actual transportation route and processing technology.

IV.Risk Early Warning and Pitfall Avoidance Guide: 3 High-Frequency "Hidden Costs"

There are 3 types of risks often hidden in Tianjin raw material import.Zhongshitong helps clients avoid them through a "double review mechanism":

• Demurrage Fee Trap: The storage fee at Tianjin Port is 0.5 yuan/ton/day.If the bill of lading is not exchanged in time,the freight forwarder may add charges temporarily.A client failed to verify the "original bill of lading exchange fee" (which should actually be 500 yuan per ticket,but the freight forwarder reported it as 1200 yuan),leading to an additional expenditure of 700 yuan.
• Exchange Loss Hedging Plan: The fluctuation of USD/RMB exchange rate in 2026 reaches ±5%.It is recommended to lock the exchange rate 3 days in advance (through forward foreign exchange settlement and sale at banks) to avoid cost overrun due to exchange rate changes.
• Consistency of Declaration Elements: Tianjin Customs has added a "Declaration Element Verification System",and the brand,model,and specifications must be 100% consistent with the actual goods.An enterprise imported "stainless steel rods" and failed to mark "diameter tolerance ±0.05mm",which was judged as "non-standard declaration",resulting in a fine of 5000 yuan.

V.Unique Advantages of Zhongshitong’s Tianjin Agency: Shanghai Headquarters + National Port Coordination

As the Tianjin branch of Shanghai Zhongshitong,we can provide:

• One-Stop Off-Site Customs Declaration: Enterprises do not need to establish branches in Tianjin.They can directly access Tianjin Port data through the Shanghai headquarters system to achieve seamless connection of "off-site declaration,local inspection".
• 24-Hour Emergency Response: During holidays (such as Spring Festival,Ramadan),Zhongshitong has dedicated staff on-site at Tianjin Port to ensure that goods are not detained.
• Policy Dynamic Push: Real-time synchronization of Tianjin Customs’ "Inspection Blacklist" (such as a certain type of raw material being inspected 3 times in a row) to adjust the declaration strategy in advance.

In summary,the core of Tianjin raw material import agency is "compliance + efficiency".Through 20 years of practical experience,Zhongshitong helps enterprises avoid risks such as classification errors,document inconsistencies,and inspection delays,allowing high-quality goods from around the world to enter the Chinese market safely and efficiently.
