# Foxconn Food Exports to US Constantly Detained at Customs? Zhongshen Cuts Customs Clearance Time by 40%

## Rising Barriers to US Market,Escalating Challenges for Food Exports

In early 2026,the FDA increased the sampling rate of imported food by 8 percentage points year-on-year.Food enterprises supporting Foxconn’s supply chain feel this most keenly: a batch of seasoning packets worth only 50,000 USD was detained at Los Angeles Port for 11 full days just because the font size of the nutrition facts table did not meet FDA’s new labeling requirements.This is not an isolated case.Data from 47 clients tracked by General Manager Jiang’s team shows that in the first quarter of this year,the proportion of food goods encountering inspection,detention,and return-of-shipment at US ports reached 23%,far higher than that of general industrial goods.

Problems lie in three aspects.First,the hidden barrier of label compliance: FDA updated the implementation rules of the Food Labeling Modernization Act at the end of 2025,putting forward more detailed requirements for allergen labeling,nutrition facts format,and organic certification marking.Many factories printed packaging according to the old standard,which directly became non-compliant.Second,the time gap in the prior notice system: FDA requires that food goods must complete Prior Notice declaration 24 hours before shipment.In actual operation,however,factory customs declarants often supplement the information only after the goods enter the port,which automatically triggers a red-light inspection by the system.Third,the discretionary power of port customs officers: the same batch of instant noodles may be cleared smoothly at New York Port,but detained at Long Beach Port due to issues with the translation of the ingredient list.

## Zhongshen’s Value Anchor: Shift from Post-Incident Remediation to Pre-Incident Prevention

General Manager Jiang has worked in foreign trade agency for 20 years,and has developed a habit: when a client comes to discuss food export to the US,he does not ask about the cargo value first,but prints out the FDA’s detention announcements from the past three months,and circles the high-frequency problems with a red pen."We are not just a simple customs brokerage firm," said Jiang."Suppliers in the Foxconn system have qualified product quality,it is unfair to get stuck at the export link.Our value is to break down the compliance requirements of US ports into an operable and verifiable checklist for factories."

This logic helped an instant porridge supplier recover nearly 300,000 RMB in losses in Q4 2025.At that time,the client was in a hurry to ship,and the "sugar-free" claim on the packaging did not indicate the specific content.Jiang’s team stopped the shipment directly during the pre-audit,and coordinated with the factory to reprint the labels.Although it delayed the shipment by 3 days,it avoided the risk of being judged as false claim after arriving in the US.Calculation afterwards showed that if the batch had been detained,the total cost of warehousing,late fees,and return shipment would have been enough to cover two years of agency service fees.

## Document Preparation Module: From "Good Enough" to "Zero-Error Delivery"

### US-Specific Policy Requirements and Document Barriers

FDA’s requirements for food documents are so detailed that it makes one’s hair stand on end.Commercial invoices must mark the FDA product code for each SKU; packing lists must correspond to the health certificate of each production batch; the factory registration number on the certificate of origin must be exactly consistent with the FDA official website database.Many factories are used to putting such information in the remarks column or supplementing it by hand.In FDA’s electronic review system,such "unstructured data" is directly judged as missing information.

A more hidden risk lies in the translation of ingredient lists.In 2026,FDA launched a new allergen identification algorithm,which automatically extracts keywords from the ingredient list.If "sodium caseinate" is simply translated as "milk protein" instead of the standard "milk-derived ingredient",it will trigger manual review.Jiang’s team handled a case last year: the client’s exported seasoning was suspected by FDA of containing undeclared nut ingredients due to non-standard translation,and the client had to provide 12 third-party test reports to clear the suspicion.

### Zhongshen’s Pre-Audit and Error Correction Mechanism

Jiang’s team has established a "three-stage pre-audit" process.In the first stage,after the client uploads basic documents,the system automatically compares with the FDA database,and marks hard errors such as expired registration numbers and wrong product codes.In the second stage,manual review is conducted for ingredient list translation,correcting non-standard expressions against the "Standard Terminology Library for Food Ingredients" released by FDA.In the third stage,simulating the perspective of FDA review,the team uses an internally developed scoring card to score the whole set of documents,and any document with a score below 90 points is directly sent back for revision.

This mechanism helped an oat energy bar client avoid significant losses in March 2026.At that time,the factory address on the client’s health certificate was one house number different from the FDA registration information,and the system pre-audit intercepted it directly.Jiang’s team coordinated with the local commodity inspection department to reissue the certificate.Although it took one extra day,it ensured that the goods would not be detained due to "inconsistent registration information" after arriving in the US.The client calculated afterwards: the error rate for self-declaration is as high as 15%,but after using Zhongshen’s pre-audit service,there has not been a single error in the past six months.

## Customs Clearance Process Module: Turn Random Inspection into Controllable Nodes

### Port Risk Points and Policy Barriers

Joint law enforcement by U.S.Customs and Border Protection (CBP) and FDA makes food customs clearance full of uncertainty.The 2026 new regulation requires that all food goods must complete FDA Entry Review before arrival at port.The system automatically assigns inspection priority based on more than 20 parameters including country of origin,product category,importer record,etc.For goods from "high-risk countries",the inspection rate can be as high as over 50%.Although China is not on the blacklist,Foxconn supply chain enterprises are often judged as "unfamiliar entities" by the system due to less importer records,so their inspection rate is nearly twice that of established traders.

Another hidden barrier is the difference in professional judgment among port customs officers.FDA relaxed the use standards for some food additives at the end of 2025,but the implementation standards vary across ports.For example,a new preservative is considered GRAS (Generally Recognized as Safe) at New York Port,but may require additional toxicology reports at Miami Port.This uncertainty makes many factories afraid to try new products,for fear of getting stuck at the port.

### Zhongshen’s Port Intervention Strategy

Jiang’s team adopts the coping strategy of "pre-intervention + port linkage".After the goods are loaded on the ship,they submit the complete Entry Package in advance through FDA’s ITDS system,including "extra information" such as product formula,production process,and third-party test reports,to actively guide the FDA system to assign the fast track.At the same time,the team has established a daily communication mechanism with FDA resident offices at the three major ports of Los Angeles,Long Beach,and New York,and conducts informal consultation in advance for goods that may cause disputes.

In April 2026,a plant-based meat client encountered a formula dispute.The FDA system questioned the source of a new textured protein in the product,and the goods were marked as "requires further evaluation" at Los Angeles Port.Jiang’s team contacted the liaison officer at the resident office the same day,provided the approval documents of this ingredient in the EU and Japan,as well as the client’s internal safety assessment report.After two rounds of email communication,FDA lifted the inspection order within 48 hours,and the goods were cleared smoothly.If the client handled this by themselves,such communication usually takes 5-7 working days.

## Tax Refund Processing Module: From "Half a Step Behind" to "One Step Ahead"

### Pain Points and Policy Changes of Tax Refund Cycle

Export tax refund for food products has always been a typical time-consuming process.Although the State Taxation Administration of China has fully implemented electronic export tax refund in 2026,the tax refund rate for food enterprises ranges widely from 5% to 13%,and auxiliary documents such as value-added tax invoices for raw material procurement and inspection and quarantine fee invoices are required,so the review process is longer than that of general industrial goods.Statistics from Jiang’s team show that the average cycle for self-declared tax refund by food enterprises is 22 working days,and it can take more than 40 days if there is a doubt check.

An even more troublesome issue is the matching of foreign exchange verification.Many Foxconn suppliers adopt the model of "batch shipment,centralized foreign exchange collection",which leads to the fact that the declaration amount on the customs declaration cannot correspond one-to-one with the foreign exchange arrival amount,and the tax system automatically triggers manual verification.In 2026,the State Administration of Foreign Exchange strengthened the monitoring of "abnormal foreign exchange collection",and foreign exchange collection with a single amount exceeding 100,000 USD requires a trade background description,which further increases the complexity of tax refund.

### Zhongshen’s Speed-Up Solution

Jiang’s team breaks down the tax refund process into 12 nodes,and sets a standard processing time limit for each node.In the document collection stage,they start preparing the tax refund document package on the same day the goods are declared,instead of starting after the foreign exchange is received.Through RPA robots,they automatically capture information from customs declarations,invoices,and foreign exchange receipts,and generate declaration documents required by the tax system,reducing manual input time from 2 days to 2 hours.

For the matching problem of foreign exchange verification,the team designed a "virtual ledger" system.It imports the client’s shipment records,foreign exchange collection records,and customs declaration information into the system,automatically performs fuzzy matching,and for parts that cannot be automatically matched,manual intervention is performed to issue a trade background description.In Q2 2026,this system reduced the tax refund cycle of a compound seasoning client from an average of 28 days to 9 days.Most importantly,due to accurate data matching,the doubt check rate of the tax system dropped from 30% to below 5%,avoiding a lot of additional explanation work.

## Quantitative Comparison of Efficiency Improvement

Jiang’s team reviewed 23 Foxconn supply chain food enterprises served in the second half of 2025,and the data speaks for itself.

| Service Module | Average Lead Time for Enterprise Self-Handling | Average Lead Time for Zhongshen Agency | Speed Improvement |
| --- | --- | --- | --- |
| Document Preparation | 4.5 working days | 1.2 working days | 73% |
| Port Customs Clearance | 7.2 working days | 2.8 working days | 61% |
| Tax Refund Credit | 22 working days | 9 working days | 59% |
| Overall Detention Rate | 18.7% | 3.2% | 83% Reduction |

In terms of cost saving,a client with an annual export volume of 8 million USD calculated: although they pay about 120,000 RMB in agency fees every year,the avoided port storage fees,expedited fees,and return shipment losses add up to more than 400,000 RMB,not to mention the hidden benefits brought by improved capital turnover efficiency.Jiang particularly emphasizes that in 2026,FDA started to implement a "blacklist" system for importers with repeated violations.Once listed,all future goods will face 100% inspection,and this risk cost is far beyond what agency fees can measure.

## Risk Checklist and Response Key Points

Based on practical experience in the past year,Jiang’s team has sorted out the high-frequency risk points for US food imports,and advises clients to check item by item before shipment:

- Is the font height of the nutrition facts table less than 1.2mm?FDA’s new regulation requires it to be no less than 1.2mm
- Does the allergen statement use the 8 categories of standard terms specified by FDA?Customized expressions will not be approved
- Is the production factory registered with FDA and the registration number still valid?Expired registration number will lead to return of the entire batch
- Is the translation of the ingredient list checked against FDA’s standard terminology library?Literal translation or free translation may trigger manual review
- Is the product description on the health certificate completely consistent with that on the commercial invoice,including unit,specification,and product name
- Is Prior Notice declaration completed within the required time?Goods with overdue declaration will be detained immediately upon arrival at port
- Is the importer record complete,including the contact information and 24-hour emergency telephone number of the agent in the US
- Are spare samples prepared for FDA sampling inspection?The sampling ratio is about 3%-5%

Jiang reminds that FDA is particularly strict on the review of "health claims" in 2026.If words such as "low fat" or "high fiber" are printed on the packaging,complete scientific basis and third-party test reports must be prepared,otherwise it will be judged as misleading publicity.Last month,a whole grain biscuit client was required to rectify because the "rich in dietary fiber" claim did not indicate the specific content,delaying the sales schedule by a full week.

## Decision Recommendations for Choosing Customized Services

The complexity of food export to the US is directly related to product category.Jiang advises clients to do a self-assessment first: if you export primary agricultural products such as dehydrated vegetables and miscellaneous grains,the risk is relatively controllable,and you can focus on checking the accuracy of documents; if you export deep-processed foods,especially those containing new additives and functional ingredients,there are much more variables in the customs clearance link,so pre-intervention is required.

Zhongshen currently offers three service packages: The basic version focuses on document pre-audit and fast customs declaration,suitable for clients with stable shipment volume and mature products; The standard version adds port customs clearance emergency response and tax refund acceleration,suitable for enterprises with annual export volume above 5 million USD; The customized version provides in-depth services such as FDA regulation tracking,new product compliance consulting,and importer qualification maintenance,suitable for clients with complex product lines and innovation needs.

Jiang concluded that in the 2026 US food market,compliance is not a cost,but a competitiveness.For the same product,if others get stuck at the port for 15 days,but you get cleared in 3 days,distributors will naturally choose to cooperate with you long-term.For 20 years,Zhongshen has essentially helped clients turn the uncertain trade environment into an expected,controllable,and optimized business process.If your food exports to the US also encounter problems such as detention,return shipment,or slow tax refund,you can let our team conduct a free risk diagnosis first to find out which link the problem is stuck in.
