Market Background and Practical Difficulties of Importing Southeast Asian Rubber Products to Shenzhen
In the first quarter of 2026,the import volume of rubber products at Shenzhen Port increased by 17% year-on-year,among which stationery erasers and industrial rubber components account for more than 60%.Thailand,Malaysia and Vietnam have become the main sourcing regions due to their raw material advantages and processing capacity.However,this seemingly blue-ocean market is full of hidden pitfalls in actual operation.Although rubber products are not classified as high-risk goods,they are frequently stuck in three links: ambiguous determination of China Compulsory Certification (3C),phthalate content testing under environmental standards,and mismatching between certificate of origin and proof of substantial processing.Shenzhen Customs upgraded the sampling ratio for imported consumer goods at the end of 2025,increasing the sampling inspection rate of stationery from 8% to 15%,which caught many first-time importers off guard.When Manager Zhuang purchased his first batch of erasers from Thailand last year,he failed to confirm in advance whether the product fell into the 3C certification catalog,resulting in the goods being detained at Shekou Port for two full weeks,and finally incurred nearly 30,000 yuan in container detention fees.

Core Value of Zhongshen in the Eraser Import Supply Chain
For 20 years,Zhongshen has focused on customs declaration and inspection at Shenzhen Port,and has developed a set of pre-risk identification mechanism for commodities such as erasers that look simple but involve complicated details.Our core value is not simply submitting documents,but integrating customs supervision logic into the procurement negotiation stage in advance.For example,before customers sign purchase contracts with Thai factories,Zhongshen will intervene to conduct product component analysis and confirm whether the product contains PVC material,because this directly determines whether 3C certification is required.At the same time,our team will verify whether the quality inspection report provided by the Thai side meets China’s GB 21027-2020 General Safety Requirements for Student Products,instead of only referring to EU or US standards.This in-depth intervention avoids the passive situation of discovering non-compliance only after the goods arrive at the port.Shenzhen Customs District enforces extremely strict verification on certificates of origin under the ASEAN Free Trade Agreement,so Zhongshen will guide Thai factories to prepare raw material procurement ledgers in advance to ensure the certificate of origin can withstand post-issuance verification queries.
Phased Breakdown of Import Process and Compliance Key Points
1.Document Pre-audit: Risk Control at the Source
Document pre-audit is the most critical yet most easily overlooked link in eraser import.Zhongshen requires customers to provide not only basic contracts,invoices and packing lists,but also product formula sheets,material composition percentages and function description letters.These documents determine the HS code classification and supervision condition judgment for subsequent customs declaration.In 2026,customs impose stricter requirements on the accuracy of HS code declaration.Rubber products may be classified under 4016.99 (vulcanized rubber products),9603.90 (erasers) or 3926.40 (plastic erasers).The tariff rates corresponding to different codes range from 6.5% to 10%,and the supervision conditions also vary greatly.Zhongshen’s customs team will apply for pre-ruling from the customs classification department in advance based on physical indicators such as product hardness,composition,and vulcanization status,to ensure accurate declaration.
- Component Analysis Report: Must clearly specify rubber type (natural rubber/synthetic rubber),whether it contains PVC,and plasticizer type
- 3C Catalog Determination: Confirm whether the product falls into the compulsory certification scope according to the latest 2025 announcement of the State Administration for Market Regulation
- Certificate of Origin Format: ASEAN Form E certificate must indicate the manufacturer’s name and address in the goods description column,which must be consistent with filing information
- Quality Inspection Report: Must include third-party testing data for phthalates,polycyclic aromatic hydrocarbons,heavy metal migration and other items
2.Port Customs Declaration: Analysis of Characteristics of Shenzhen Customs District

The review focus of Shenzhen Port for rubber products lies in price and classification.In 2026,customs launched a new version of risk parameter table,which automatically triggers price verification for erasers with a declared unit price lower than 2 USD/kg.When filling out the customs declaration form,Zhongshen will actively provide a description of the Thai factory’s cost structure in the remark column,including details such as natural rubber purchase price,labor cost and mold amortization,to avoid unnecessary price verification disputes.Shenzhen Bay Customs implements "immediate review upon arrival" for goods under the ASEAN Free Trade Agreement,but requires millisecond-level matching between the electronic data of the certificate of origin and the declaration information on the customs declaration.Zhongshen uses the advanced certification interface of the China International Trade Single Window to realize automatic capture of certificate of origin data and eliminate manual entry errors.For products requiring 3C certification,Zhongshen will upload the electronic copy of the certification to the customs certification system before declaration,to ensure automatic verification and approval during customs clearance.
3.Commodity Inspection: Special Quarantine Requirements for Rubber Products
The inspection focus for rubber products is not animal and plant quarantine,but consumer product safety.Shenzhen Inspection and Quarantine Center launched a new testing method in 2026,which imposes stricter limits on migratable elements in erasers.Zhongshen will send samples to the Industrial Products Testing Technology Center of Shenzhen Customs in advance for a baseline test to ensure that 19 elements including lead,cadmium and mercury do not exceed the limit.For industrial rubber components,inspection will check for banned azo dyes.Zhongshen’s experience is to arrange full testing by a third-party agency in accordance with Chinese standards before the Thai factory ships the goods,instead of waiting for sampling after the goods arrive in Shenzhen.In this way,even if the goods are selected for inspection,a qualified report can be issued quickly,avoiding long waiting periods.
| Test Item | Standard for Student Erasers | Standard for Industrial Rubber Components | Common Problems |
|---|---|---|---|
| Phthalates | DBP+BBP+DEHP≤0.1% | Determined by application | Thai suppliers often use EU standard 0.15% limit |
| Migratable Elements | Lead≤90mg/kg | Lead≤1000mg/kg | Contamination risk from pigments |
| Polycyclic Aromatic Hydrocarbons | Total amount≤10mg/kg | Determined by material type | Residue from carbon black raw materials |
| 3C Certification | Products in the catalog require valid certification | Most are exempt from certification | Missing declaration caused by incorrect classification |
Real Case: Manager Zhuang’s Experience of Importing Thai Erasers
Manager Zhuang’s company mainly operates cultural and creative products,and planned to import a batch of shaped erasers from Thailand at the end of 2025,with a total value of about 50,000 USD.When first engaging in import business,Manager Zhuang believed that erasers are ordinary stationery and only basic documents are required.After accepting the order,Zhongshen first asked the Thai side to provide the product formula,and found that this batch of erasers is made of PVC with cartoon shapes,which belongs to "plastic stationery" in the 3C certification catalog.At this time,the goods were already on the sea,and it was too late to re-apply for certification.Zhongshen’s solution was: according to Announcement No.12 of 2025 issued by the State Administration for Market Regulation,the product meets the exemption conditions for "small-batch or sample imports for R&D and testing".We guided Manager Zhuang to prepare the R&D project document,test plan,and follow-up disposal commitment,and applied for an exemption certificate from Shenzhen Administration for Market Regulation.Meanwhile,we sent samples for inspection before the goods arrived at the port to ensure indicators such as phthalates meet the standard.After the goods arrived at Shekou Port,Zhongshen declared customs with the exemption certificate,and the goods were released normally after customs verification.Although the whole process took 5 more working days than normal import,it avoided the risk of return or destruction.Manager Zhuang calculated that if he operated on his own,he would not only fail to solve the 3C problem,but also lose at least 80,000 yuan in total for container detention fees,inspection fees and return shipping.This experience made Manager Zhuang realize that the value of a professional agent is to resolve risks before the goods arrive at the port.
Practical Value of Professional Agency for Import Efficiency and Risk Control
What Zhongshen has accumulated over 20 years is a set of operation system synchronized with the supervision rhythm of Shenzhen Customs.In 2026,customs implemented the "voluntary disclosure" system,which allows enterprises to be exempt from punishment if they find declaration errors through self-inspection.Zhongshen will regularly conduct import data review for customers,actively check potential risks in classification,price,origin and other aspects,and report to customs for rectification in advance.This service model converts customers’ compliance cost from "post-event penalty" to "pre-event prevention".In terms of timeliness,Zhongshen has a thorough understanding of operation hours at all ports in Shenzhen: Shekou Port does not arrange inspections on Saturday afternoons,Yantian Port does not accept inspection appointments for Sunday night shifts,and Shenzhen Bay Customs gives priority to document review for ASEAN goods.Arranging declaration time based on these details can save customers an average of 2-3 natural days.More importantly,Zhongshen has established long-term cooperation mechanisms with many rubber product factories in Thailand and Malaysia,and can guide foreign suppliers to prepare documents in accordance with Chinese standards,realizing standardization at the front end of the supply chain.This end-to-end control capability cannot be provided by ordinary customs brokerage firms.Eraser import seems simple,but it actually requires in-depth understanding of multiple dimensions including standards,certification,testing,classification,price verification and rules of origin.The value of Zhongshen is exactly integrating these scattered professional knowledge into an executable and predictable import solution.
