2026 Dye Import Customs Clearance Agency: Full-Process Compliance Guide for Shanghai Port

Core Processes and Compliance Key Points for Dye Import Customs Clearance Agency

As an important raw material in the chemical industry,dye import customs clearance involves multi-link supervision.In Mr.Cheng’s case of importing acidic dyes from India,the goods were detained at Yangshan Port for 3 days due to incorrect HS code classification not confirmed in advance,resulting in demurrage fees exceeding 80,000 yuan.This lesson highlights that dye import agencies need to control compliance details from the source.

1.Accurate HS Code Classification: The Lifeline of Chemicals Customs Clearance

Incorrect dye classification is the primary cause of customs clearance delays.Common mistakes include misclassifying direct dyes as 32041200 (acidic dyes),or classifying them under 3403 (detergents) instead of 3204 (dyes) due to a too-high proportion of additives.The newly added "Explanatory Notes to the Commodity and Item of the Import and Export Tariff Schedule" in 2026 clearly states that dyes must meet the core judgment standard of "taking coloring as the main function."

• Key: Submit the "Pre-classification Application Form" in advance,with a product composition list (e.g.the proportion of dispersant in disperse dyes must be less than 5%)
• Case: The disperse dyes represented by Manager He were classified as 32041900 due to containing 10% non-active additives,which is 3 percentage points higher than the original 32041300 tax rate
• Tool: Zhongshitong locks the code in advance through the General Administration of Customs’ "Pre-classification Ruling System" to reduce the risk of classification disputes

2.Hazardous Goods Filing and MSDS Review: The "Critical Gate" of Dye Customs Clearance

About 60% of dyes are hazardous chemicals.The 2026 new version of the "Hazardous Chemicals Catalog" adds 12 dye-related substances.Key points to note during filing:

Zhongshitong recommends: MSDS must be issued by a chemical enterprise registered in China,and the newly added "GHS Classification" in 2026 must correspond to the United Nations’ "Globally Harmonized System of Classification and Labeling of Chemicals".Mr.Mei’s European dyes were detained by commodity inspection because the MSDS did not update the carcinogenic classification,and the problem was finally solved by urgently submitting the new version of MSDS.

3.Import License and Certificate of Origin: Policy Thresholds and Cost Optimization

Dye import licenses mainly target: ① Dyes on the newly added anti-dumping tax list in 2026 (e.g.anthraquinone dyes from the EU); ② Dyes subject to export license management (e.g.pigments containing heavy metals).Zhongshitong reduces costs through the following plans:

• Tariff planning: Using RCEP Certificate of Origin,the tariff for dyes from Southeast Asia can be reduced from 5% to 0
• Document pre-review: Check the "Final Destination" column of the Certificate of Origin in advance to avoid disputes over "offshore processing" identification
• Policy early warning: Monitor the "Import License Application Guide" on the official website of the General Administration of Customs in real time to avoid underreporting of dyes requiring 3C certification

4.Shanghai Port Customs Clearance Practice: Risk Prediction from Price Assessment to Release

Shanghai Port focuses on the following in dye price assessment: ① Whether the transaction price is consistent with the price of similar imported goods in the same period; ② Whether there is a "transaction with special relationship" (e.g.high-price procurement between related enterprises).In Manager Qu’s dye import case,due to not providing "third-party price proof",the customs assessed the price and required a supplementary tax of 200,000 yuan.

Points to note in commodity inspection: ① Submit the "Inspection and Quarantine Application Form" 48 hours in advance; ② Prepare backup samples simultaneously for sampling testing; ③ The newly added "Harmful Aromatic Amine Detection in Dyes" in 2026 needs to be declared separately.

5.Zhongshitong’s Differentiated Services: National Port Linkage and Risk Control System

Relying on its Shanghai headquarters,Zhongshitong achieves: ① Remote declaration at national ports (direct pickup from hazardous goods yards at Ningbo Port,fast transshipment at Shenzhen Port); ② Global agency network (pre-customs clearance services at Antwerp Port in Europe and Laem Chabang Port in Southeast Asia); ③ Risk early warning system (automatically captures customs price assessment models and commodity inspection frequency).

The newly added "Demurrage Fee Hedging Plan" in 2026: For goods with demurrage exceeding 48 hours,the "application for exchange fee reduction" is automatically initiated.Mr.Cheng’s goods saved 32,000 yuan in storage fees as a result.

6.Dye Import Customs Clearance Risk List and Response Guide

• Compliance Red Lines: ① Declaration elements do not match the actual goods (e.g.the deviation of the main color number of the dye from the filing form is >3%); ② MSDS does not mark the "environmental hazard" clause (e.g.heavy metal residues); ③ Certificate of Origin does not indicate "non-originating components"
• Cost Traps: ① Exchange fees are calculated based on the "number of bills of lading" (actually 3 fees charged for 1 bill of lading); ② Demurrage fees are accumulated by "natural days" (weekends and holidays are charged as usual)
• Response Plans: ① Establish a "dye import compliance file" including HS code change records; ② Sign a "demurrage fee early warning agreement" with the shipping company,and Zhongshitong intervenes in advance
