# Full Process Analysis and Compliance Operation Guide for Import PET Customs Brokerage

In 2026,the domestic polyester industry chain maintains high demand for upstream PET raw materials,and a large amount of high-quality PET chips and bottle flakes still need to be imported from South Korea,Taiwan region,and Southeast Asian countries.However,with the normalized implementation of solid waste supervision policies,ports have become increasingly strict in identifying the solid waste attributes of imported PET,and the standards for document compliance and physical goods inspection have been significantly raised.Many enterprises often face order rejection or port detention during inspection due to incorrect HS code classification or non-standard labeling in the declaration process,leading to a sharp increase in logistics costs.

In response to this situation,Zhongshen has built a mature import PET customs brokerage service system based on more than 20 years of operational experience.We not only handle simple declaration procedures,but also deeply participate in trade compliance consulting,document pre-review,and logistics coordination to ensure fast circulation of goods on the premise of compliance.By integrating resources of customs declaration,inspection declaration,international transportation,and foreign exchange settlement,Zhongshen can provide customers with closed-loop services from overseas delivery to domestic pickup.

## Document Pre-review and Compliance Confirmation

Before the goods arrive at the port,document preparation is the key factor determining the customs clearance speed.Supervisor Ou pointed out that in 2026,the customs system’s review of "consistency of documents" has been upgraded to intelligent comparison,and any minor data deviation may trigger a system warning.Zhongshen will immediately launch the pre-review process after receiving the bill of lading,invoice,packing list,and contract provided by the customer.

- **Basic document verification:** Focus on checking trade terms,transaction amount,and country of origin information to ensure tight logical relationships between documents and avoid basic errors such as "gross weight exceeding net weight".
- **Qualification review for specific products:** For PET raw materials,it is necessary to confirm whether the Material Safety Data Sheet (MSDS) and Chinese hazard public label are attached.For food-grade PET,a hygiene certificate or test report conforming to GB standards must also be provided.
- **Certificate of origin and agreed tariff rate:** For goods from South Korea,ASEAN and other regions,Zhongshen will assist enterprises in correctly filling in the preferential certificate of origin to ensure they enjoy the agreed tariff rate and directly reduce import tax burden.

## HS Code Classification and Declaration Element Specification

HS code classification of PET products is a technical core part of customs brokerage,which is directly related to tax rates and supervision conditions.In actual operation,the classification boundary between polyester chips and polyester waste scraps is very easy to be confused,which is also the focus of customs inspection.

Zhongshen’s operation team will conduct accurate classification based on standards such as the national standard GB/T 14190-2017,combined with the physical form of the goods.Polyester chips in primary form are usually classified under heading 3907.60; for bottle flakes with certain cleanliness,the subheading shall be determined according to specific fiber length and viscosity indicators.We will strictly standardize elements such as "appearance","component content","monomer unit","proportion" and "signing date" during declaration to ensure that the declaration content fully matches the attributes of the actual goods.

## Coordination of Port Customs Declaration and Commodity Inspection

After the goods arrive at the port,Zhongshen will seamlessly connect the customs declaration and commodity inspection processes.For PET products listed in the legal inspection catalogue,inspection declaration procedures must be completed before customs declaration.In 2026,the proportion of on-site inspections of imported chemicals by customs remains at a high level,focusing on checking whether the goods contain impurities,are contaminated,or carry the risk of mixed solid waste.

During the inspection process,Zhongshen’s on-site customs brokers will actively cooperate with the customs in unpacking inspection,and assist in explaining characteristics such as packaging status and color uniformity of the goods.In case of sampling for testing,we will follow up the laboratory test results as soon as possible.Once abnormal results are found,we will immediately launch the emergency plan,discuss technical rectification or return plans with customers,and minimize the occurrence of container detention fees and storage fees.

## Comparison of Import Risks and Supervision Requirements for PET Products

To more intuitively demonstrate the differences of different types of PET products in the import process,Zhongshen has compiled the following comparison table of supervision requirements to help enterprises avoid risks in advance when signing trade contracts.

| Product Type | Common HS Code | Supervision Conditions | Key Risk Points | Zhongshen’s Response Strategy |
| --- | --- | --- | --- | --- |
| High-viscosity polyester chips | 3907.6090 | A (Customs Clearance Form for Inbound Goods) | Tax rate difference caused by false component declaration | Review test reports in advance,and declare viscosity value accurately |
| PET bottle-grade chips | 3907.6990 | A/B | Hygiene certificate required for food-grade products | Confirm non-edible use or assist in handling relevant hygiene certificates |
| PET clean flakes (recycled) | 3907.6990,etc. | A/9 (Import prohibition restriction) | Extremely high risk of solid waste identification | Strictly review the source of goods,and reject orders with solid waste risks |

## Practical Case Sharing: Avoiding Label Risks

In early 2026,a local plastic modification factory in Shanghai entrusted Zhongshen to act as an agent for importing a batch of PET chips from South Korea.The batch of goods was used to produce industrial-grade plastic parts,and the customer believed that there was no need to provide food-grade related documents.However,during the document pre-review stage,Supervisor Ou found that the MSDS provided by the overseas supplier and the outer packaging of the goods were printed with the words "Food Contact Grade".

This detail aroused high alert from Supervisor Ou.If declared as ordinary industrial raw materials while the actual packaging is marked as food-grade,it is very likely to be identified by customs as inconsistent between documents and goods,and even suspected of evading commodity inspection.Supervisor Ou immediately contacted the customer to explain the situation,and suggested that the enterprise require the overseas supplier to replace the packaging that meets industrial-grade standards,or declare truthfully and supplement the relevant conformity statement during declaration.

Finally,before the goods arrived at the port,Zhongshen assisted the enterprise in conducting multiple rounds of communication with the overseas supplier,reissued the certification documents conforming to industrial use,and modified the declaration elements.After the goods arrived at the port and were declared,the customs system released them directly without any inspection detention.The customer highly recognized Zhongshen’s careful review,believing that this measure directly avoided tens of thousands of yuan in amendment and cancellation fees and potential administrative penalty risks.
