# US Raw Material Import Customs Brokerage: 2026 Practical Guide to Full Compliance Clearance Process

## Regulatory Environment and Practical Difficulties of US Raw Material Import

In 2026,the United States remains an important raw material supply source for China’s manufacturing industry,covering multiple categories such as chemical intermediates,food additives,pharmaceutical excipients and deep-processed agricultural raw materials.Data from Shanghai Port shows that more than 300 declarations of US raw material imports are processed every month,among which about 15% will trigger customs inspection or commodity inspection sampling.In practice,enterprises often face three typical dilemmas: first,mismatch between FDA registration number and production facility number leads to declaration rejection by the customs clearance system; second,GMO ingredient labeling fails to comply with the new regulations of the Ministry of Agriculture and Rural Affairs,and the entire batch of goods is required for technical rectification; third,incorrect calculation of anti-dumping duty deposit causes extra capital occupation.These bottlenecks not only delay production line supply,but may also trigger compliance penalties.

## Positioning of Zhongshen in the Raw Material Import Chain

Zhongshen is not merely a traditional customs broker,but a compliance steward embedded in the front end of customers’ supply chain.We have liaison offices in Los Angeles and Houston,which can complete supplier qualification verification and document pre-audit before cargo loading.This pre-service model transforms the passive declaration of traditional customs brokers into active risk interception.Last year,a Shanghai biopharmaceutical enterprise we served had a problem that the CAS number on the COA certificate of its purchased US pharmaceutical excipients did not match the declared tax number.This problem was intercepted during the pre-audit stage,avoiding potential container detention fees and document amendment fees after arrival,directly saving about 80,000 RMB in costs.This value is reflected in the accurate grasp of regulatory details,rather than simple process agency.

## Breakdown of Full Import Customs Declaration Process

### Stage 1: Document Pre-audit and Pre-compliance

The document system for US raw material import has obvious category differences.Take food contact materials as an example,in addition to conventional invoices,packing lists and bills of lading,a third-party test report complying with GB 4806 series standards is mandatory,and test items must correspond one-to-one with specific ingredients of the raw materials.Zhongshen’s pre-audit team will check page by page whether the migration data and sensory requirement indicators in the test report match the declared use.There was once a shipment of food-grade lubricating oil imported from Georgia,US.The NSF certification certificate provided by the customer did not include the H1 category mark,so we required the supplier to supplement a compliance statement complying with China’s GB 9685.This adjustment was completed before loading,avoiding the risk of being judged as unqualified by commodity inspection after arrival.

Core actions in the pre-audit stage include:

- Check whether FDA registration information is within validity period,and whether production facility number matches the shipping factory
- Verify whether GMO ingredients are labeled in accordance with regulations,especially for raw materials derived from corn and soybeans
- Confirm whether the calculation base of anti-dumping duty deposit includes ocean freight and insurance premium
- Verify whether MSDS or SDS safety data sheet complies with China’s GHS standards
- Check whether wooden packaging has the required IPPC heat treatment mark

### Stage 2: Port Customs Declaration and Tax Calculation

After cargo arrival,the key of customs declaration lies in the accuracy of HS code classification and the reasonableness of price declaration.The declared price of US raw materials often involves complex clauses such as royalty and resale revenue sharing,and customs has increasingly strict price verification for such non-trade payment items.Zhongshen’s customs declarers will check payment records with the customer’s finance department before declaration,to ensure that the declared price covers all taxable items.General Administration of Customs of China Announcement No.3 of 2026 clearly stipulates that for technical licensing fees of chemical raw materials,even if signed in separate contracts,as long as they are related to imported goods,they should be included in the customs value.We once represented a shipment of special polymer imported from the US.The customer initially did not include the technical licensing fee in the goods value,and we prompted them to actively disclose the fee,avoiding the credit downgrade risk caused by subsequent customs audit.

Another key focus of tax calculation is the application of rules of origin.US raw materials enjoy most-favored-nation tariff rate,but some products are covered by the additional tariff exclusion list for US-origin goods.Zhongshen’s customs system updates exclusion list batches in real time,and automatically matches whether the customer’s product is on the list.In October last year,a shipment of polyvinyl alcohol imported from Texas,US successfully applied the exclusion through our system comparison,saving the customer about 230,000 RMB in additional tariffs.

### Stage 3: Commodity Inspection,Inspection and Release

The inspection focus of US raw materials concentrates on three dimensions: safety,hygiene and environmental protection.Chemical raw materials need to be checked for excessive VOC content,food raw materials need to be checked for pathogenic bacteria and heavy metal indicators,and agricultural raw materials need to pay attention to pesticide residues and invasive alien species risks.Zhongshen has resident staff at Shanghai Waigaoqiao and Yangshan Port,who can follow up inspection dynamics in real time.The most common cause of delay in the inspection link is the long sampling and testing cycle,especially for items involving new testing methods,laboratory queuing can last up to two weeks.Our response strategy is to communicate with the port laboratory in advance: use the rapid testing channel for conventional items,and coordinate customers to provide spare samples in advance for items requiring external testing,to achieve parallel operation.

Last year,we handled a shipment of erythritol (food additive) imported from California,US.After sampling,the commodity inspection department required testing of lead and arsenic content,and the laboratory notified that it would take 5 working days.We simultaneously launched the customer’s production plan evaluation,coordinated the warehouse to provide the same batch retained sample,and finally completed the release on the day the test report was issued.The total port detention time was compressed to 3 days,60% shorter than the conventional process.

## Typical Case: Risk Avoidance for Food Additive Import

Mr.Shi’s company mainly operates functional beverages and needs to import a compound additive containing new resource food ingredients from the US.This ingredient has no domestic use history in China and belongs to a regulatory gray area.After accepting the order,Zhongshen first organized the customs and legal team to conduct research and judgment,confirmed that although the ingredient is not in the new resource food catalog,all its monomer ingredients meet the use standards of GB 2760.We assisted Mr.Shi to submit the administrative license application for new food raw materials to the National Health Commission,and at the same time negotiated with the US supplier on a batch shipment plan.The first batch of goods was classified as R&D samples,and applied the supervision mode of personal items for rapid customs clearance.Subsequent batches were formally declared as general trade after the administrative license was obtained.The whole cycle took 4 months,which is slower than conventional import,but ensures full compliance.Mr.Shi feedback afterwards that if he declared directly according to the original plan,it would most likely be judged as unqualified and returned,which would not only lose the payment for goods,but also delay the product launch window.

## 2026 Regulatory Trend and Countermeasure Suggestions

In 2026,the regulation of US raw material import shows three clear trends: first,data interconnection between customs and the State Administration for Market Regulation is strengthened,and the actual use of raw materials after import will be traced and verified; second,environmental protection indicators have become the core of commodity inspection,especially products involving PFAS will face stricter scrutiny; third,the frequency of dynamic adjustment of countermeasure lists is accelerating,so enterprises need to establish a rapid response mechanism.Zhongshen’s suggestion is to establish a compliance file library for raw material import,electronically archive documents,test reports and release records of each batch of goods,forming a traceable evidence chain.At the same time,it is recommended that enterprises add a responsibility sharing clause for regulatory policy changes when signing purchase contracts with US suppliers,to avoid losses caused by sudden external policy changes.

There are significant differences in regulatory priorities for different raw material types,the specific comparison is as follows:

| Raw Material Category | Core Regulatory Regulation | Common Risk Points | Zhongshen’s Countermeasure |
| --- | --- | --- | --- |
| Chemical Intermediate | Catalogue of Hazardous Chemicals | Incorrect CAS Number Classification | Pre-declaration system,obtain hazardous chemical identification in advance |
| Food Additive | GB 2760-2026 | Over-range Use | Formula pre-audit,check usage limit |
| Pharmaceutical Excipient | Drug Administration Law | Failure of Associated Review | Check status on CDE registration platform |
| Agricultural Raw Material | Law of the People’s Republic of China on Entry and Exit Animal and Plant Quarantine | Quarantine Harmful Organisms | Require US side to issue phytosanitary certificate |

The core value of choosing a professional agent is to convert scattered regulatory requirements into an executable operation list.Zhongshen handles more than 500 US raw material import businesses every year,and accumulates not only port resources,but also in-depth understanding of regulatory logic.We can help customers reduce the inventory turnover days of raw materials by 15-20 days under the premise of compliance,directly releasing working capital.This efficiency improvement comes from accurate calculation and optimization of time cost in each link,rather than simple expedited customs declaration.For enterprises relying on US raw materials,stable supply chain is more important than low cost,and professional agent is exactly the guarantee mechanism for stability.
