Core Compliance Requirements for Colorants Import Customs Declaration in Shanghai (2026 Update)

Colorants are key chemical products under customs supervision.In 2026,Shanghai Port has further refined declaration rules for this category,with significant differences in declaration requirements based on whether they are hazardous chemicals.Many importers are unclear about the classification standards,which often leads to issues such as missing documents and inconsistent declarations,directly resulting in cargo detention,fines,or even return shipment.

Common Pitfall Cases of Colorants Import at Shanghai Port

Previously,I worked with Mr.Liao from Ningbo.At the end of 2025,he imported 3 containers of acrylic colorants from South Korea to supply local coating manufacturers in Zhejiang.He entrusted a local freight forwarder for declaration,who mistakenly classified the anti-dumping colorants under HS code 3204 into the general cargo code 3206,underdeclaring 23% of the anti-dumping duty.Upon arrival,the cargo was immediately put under customs control,detained at the port for 12 days,resulting in over 80,000 RMB in demurrage.If delayed for another 7 days,he would have to pay 120,000 RMB in order liquidated damages to his client.

Upon receiving his request for assistance,we immediately retrieved the cargo’s MSDS and third-party component testing report,reorganized the HS classification logic,and verified that the batch was indeed within the anti-dumping duty scope.We proactively submitted a correction declaration application to the customs,paid the corresponding supplementary tax,and coordinated with the port commodity inspection department to prioritize component verification.Finally,clearance and release were completed within 3 days,with only an additional 20,000+ RMB in port detention-related costs,avoiding greater losses.

Practical Operation Guide for Colorants Import Agency at Shanghai Port

Combined with the latest 2026 regulatory rules at Shanghai Port,importers need to complete 4 core preparations in advance for colorants import declaration,which can reduce the clearance abnormal rate by over 90%:

• Complete document pre-verification 7 days in advance: All documents must be submitted for review in advance,including Chinese and English MSDS,origin certificate,packing list,invoice,and trade contract.For hazardous categories,a hazardous property classification identification report must be prepared in advance.In 2026,Shanghai Port requires hazardous chemicals to complete hazardous declaration 48 hours in advance; failure to declare will result in direct cargo detention.The component proportion,flash point and other parameters in the MSDS must be completely consistent with the actual goods; a deviation of more than 5% will directly trigger customs control.
• Accurate HS code classification: Colorants involve 17 8-digit HS codes,with huge differences in tariff and anti-dumping duty rates corresponding to different codes,up to 38.7%.In 2026,Shanghai Customs launched an AI pre-verification system for chemical declaration,which can directly compare historical declaration data and component testing results.Classification deviations will directly trigger price assessment verification or even anti-smuggling investigations.We provide free pre-classification services to ensure 100% compliance with regulatory requirements.
• Prepare in advance for port inspection: The three major ports in Shanghai—Yangshan,Waigaoqiao,and Pudong Airport—have different inspection focuses for colorants.Yangshan Port focuses on verifying the authenticity of origin,Waigaoqiao focuses on packaging compliance checks,and Pudong Airport focuses on component testing.For goods from RCEP member states,the origin standards in the origin certificate must be verified in advance to ensure compliance with tariff reduction requirements and avoid being unable to enjoy preferential treatment after arrival.
• Lock in cost calculation in advance: Clarify the charging standards for document exchange fees,THC,port miscellaneous fees,and commodity inspection fees in advance to avoid hidden price increases by freight forwarders.Under EXW terms,lock in the cost nodes for overseas pickup and international transportation in advance; under FOB terms,anticipate the demurrage risk caused by shipping schedule delays in advance.We provide a fully transparent fee list,with all charges disclosed in advance and no hidden costs.

2026 Colorants Import Risk Warning

In 2026,there are three updates to the regulatory requirements for colorants that importers need to focus on: First,some acrylic colorants imported from the EU,South Korea,and Japan are still in the anti-dumping duty period.Those who fail to declare anti-dumping duty proactively will be required to pay supplementary tax plus a fine of 0.5-5 times the unpaid amount.Second,if the packaging of hazardous colorants does not meet the ,the cargo will be directly required to be returned,with all return costs borne by the importer.Third,the RMB exchange rate fluctuation range will increase in 2026.Significant exchange rate fluctuations at the tax payment node may cause additional exchange losses.We can assist in connecting with compliant foreign exchange locking services to reduce exchange loss risks.
