Detailed Analysis of Imported Valve Agency Service Procedures and Compliance Requirements

Background and Common Difficulties of Valve Import

In 2026,the demand for imported valves from high-end manufacturing,new energy vehicles,pharmaceuticals and other industries in Shanghai and surrounding areas continues to rise,with an annual growth rate of 18%.Among them,high-pressure valves and food-grade valves from Germany and Japan have become the main purchasing targets of domestic enterprises due to their high precision and strong corrosion resistance.However,many purchasing managers report that imported valves often delay customs clearance due to inconsistent documents and unclear commodity inspection standards,and even face the risk of return shipment.

Take German high-pressure valves as an example,the EU updated the CE certification standard in 2026,and the old version of certification is no longer valid.Some enterprises failed to update certification documents in time,resulting in failure to declare customs after cargo arrival at the port; Japanese food-grade valves need to comply with China’s GB 150-2011 Pressure Vessels standard.If the corresponding test report is not provided,the commodity inspection authority will require supplementary inspection,leading to high storage fees for cargo detained at the port.

Core Role of Zhongshen in Valve Import

Zhongshen has been focusing on import agency for over 20 years.Targeting the special requirements of valve import,it can control the whole process from document pre-review to commodity inspection release,helping enterprises avoid compliance risks.Its core advantage lies in its thorough understanding of certification standards and commodity inspection requirements for valves from different origins,and it has established a stable coordination mechanism with customs brokers and commodity inspection authorities at all ports in Shanghai.

In March 2026,a Shanghai-based auto parts enterprise (with purchasing managed by Ms.Qin) planned to import 100 units of German TÜV certified high-pressure hydraulic valves for a new energy vehicle production line.As the enterprise imported special equipment valves for the first time,it was not familiar with commodity inspection requirements,and the prepared documents lacked the Import Safety and Quality License for Special Equipment.After learning about the issue,the Zhongshen agency team intervened for pre-review 3 days in advance,assisted the enterprise to contact the German supplier to supplement the license,and coordinated with the special equipment department of Shanghai Commodity Inspection Bureau,notifying cargo information in advance.Finally,commodity inspection and release were completed within only 48 hours after cargo arrival at the port,5 days earlier than the enterprise expected,avoiding production line shutdown loss (the daily output value of this production line is about 200,000 RMB).

Full-stage Disassembly of Valve Import Process

1.Document Pre-review Stage

Document requirements for valve import vary greatly depending on origin and application,which is one of the core difficulties in the import process.

Valve-specific Compliance Requirements:

• German valves: TÜV Rheinland certification (2026 version),EU CE certification are required; high-pressure valves additionally need the Import Safety and Quality License for Special Equipment
• Japanese valves: JIS B 2001 standard test report is required; food-grade valves need to be marked with 316L stainless steel material
• American valves: ASTM A182 standard certification,membership certificate of Valve Manufacturers Association (VMA) of the United States are required

Assistance from Zhongshen: When Ms.Qin’s enterprise imported German high-pressure valves for the first time in 2025,it mistakenly submitted a copy of TÜV certification as the original.Zhongshen spotted the problem during pre-review and assisted in supplementing the original document,avoiding customs clearance delay.Zhongshen’s document team first verifies the validity of certification documents (some old-version CE certifications became invalid in 2026),then confirms the HS code matching on the certificate of origin (valve HS codes involve multiple sub-items under heading 8481,incorrect matching will lead to tariff difference).

2.Port Customs Declaration Stage

Valves are legally inspected commodities.When declaring customs,the commodity inspection pre-declaration form must be submitted simultaneously,and some valves with special materials also need to declare material composition.

Valve-specific Requirements:

• High-pressure valves need to be marked "Special Equipment" on the customs declaration form,and submit a pressure test report
• Valves containing nickel-based alloy and titanium alloy need to declare material composition,to avoid inspection caused by inconsistent composition
• Food-grade valves need to be marked "For food contact" and provide safety test report

Assistance from Zhongshen: In 2026,Mr.An’s enterprise imported Japanese stainless steel valves,the HS code was incorrectly filled as 84818000 (ordinary valves),while the correct code should be 84813000 (high-pressure valves).Zhongshen checked and adjusted the code before customs declaration,reducing the tariff from 10% to 6%,helping the enterprise save about 80,000 RMB in tariff.Meanwhile,Zhongshen has established a green channel with customs brokers at Yangshan Port and Waigaoqiao Port in Shanghai,giving priority to customs declaration for valve cargo.

3.Commodity Inspection Stage

Commodity inspection is a key link in valve import.Inspection focuses vary for valves with different applications.If they do not meet Chinese standards,they will be required to be returned or destroyed.

Valve-specific Inspection Requirements:

• Food-grade valves: need to comply with GB 150-2011 standard,inspection focuses on material safety of food contact parts
• High-pressure valves: on-site spot check of pressure test value,to confirm whether it meets the marked rated pressure
• Corrosion-resistant valves: inspection focuses on corrosion resistance of surface coating,to confirm whether it meets application environment requirements

Assistance from Zhongshen: In 2026,Mr.Lan’s enterprise imported German food-grade valves,and failed to provide the corresponding test report conforming to GB 150 standard.Zhongshen contacted a third-party testing institution and completed supplementary inspection on-site at the port,passing commodity inspection in only 2 days,avoiding storage fees caused by cargo detention (storage fee at Shanghai port increases by 0.5 RMB/kg per day,this batch of goods weighs 12 tons,so one-day detention causes 6000 RMB loss).

Comparison of Compliance Requirements for Valves from Different Origins

Value Summary of Zhongshen Agency Service

In 2026,competition in the valve import market intensifies,and compliance requirements continue to upgrade.With more than 20 years of industry experience,Zhongshen controls the whole process from document pre-review to commodity inspection release targeting the special requirements of valves from different origins,helping enterprises avoid more than 30% of compliance risks,and the average customs clearance time is shortened to within 3 days.

Many enterprises feedback that after choosing Zhongshen’s agency service,the cost of imported valves is reduced by 15%,efficiency is increased by 40%,and they can respond to domestic production demand faster.For example,when the pharmaceutical enterprise managed by Supervisor Qi imported Japanese food-grade valves in 2026,Zhongshen assisted to complete commodity inspection pre-declaration in advance,and the cargo was released 2 days after arrival at the port,meeting the urgent demand of the pharmaceutical production line.
