Compliance Guide for Imported Grease Customs Brokerage & Solutions for Classification, Valuation, Inspection & Quarantine Issues

Key Compliance Challenges of Imported Grease

Grease belongs to chemical products,and is divided into mineral-based,synthetic-based and bio-based according to its components,corresponding to different regulatory requirements.I have encountered Manager Ji from Jiangsu once,who imported bearing-specific grease from Germany.When declaring independently,he classified the HS code under "other chemical products",with a tariff difference of 1.5 percentage points.Incomplete declaration of components led to AI-controlled inspection by customs,the goods were detained at the port for 12 days,generating nearly 9,000 yuan in detention charges,and delaying the delivery schedule to the downstream main engine manufacturer.

In 2026,customs has upgraded the consistency inspection for chemical declarations.The system automatically compares declaration information,bill of lading information and original manufacturer’s invoice information.Incorrect or missing classification will more easily trigger controlled inspection compared with previous years.Advance pre-classification is the first hurdle in customs clearance.We have compiled classification references for common imported grease:

Key Operation Points of Four Core Links in Imported Grease Customs Clearance

• Customs Valuation: Imported grease is mostly traded under EXW or FOB terms.Many cargo owners omit reporting overseas freight,insurance premiums and patent fees.In 2026,customs has connected to container loading and freight data of major global ports.Transaction prices will be automatically verified during valuation.Preparing payment vouchers,original manufacturer’s invoices and trade contracts in advance can avoid price disputes delaying customs clearance.
• Inspection & Quarantine Pre-review: Whether it is general cargo or dangerous goods,MSDS must be pre-reviewed before import to confirm components,flash point and hazard classification.Dangerous goods need to affix hazard labels compliant with China’s GHS standard.According to our statistics,30% of detained imported grease in the past three years were caused by non-compliant hazard label format or content,which can be fully avoided in advance.
• Animal and Plant Quarantine: Some bio-based greases are processed from animal fats and oils,and need to provide an official non-animal epidemic processing certificate from the country of origin when importing.Otherwise,they will be selected for sampling inspection,which takes at least 7 days and generates demurrage charges.
• Import License Application: Special-purpose grease requires an automatic import license.We can process the pre-review and issue the license in Shanghai,which is valid at all ports nationwide without re-application.

Risk Warnings for Imported Grease Brokerage That Must Be Known in Advance

Last year,Ms.Pu from Ningbo imported food-grade grease from Dubai.She booked space with an overseas freight forwarder.When exchanging the bill of lading,the exchange agent charged three times the market price for the document exchange fee.It coincided with Ramadan in Dubai,so the shipping company closed booking earlier,the container arrived at the port 5 days ahead of schedule,and the cargo owner was not ready with documents,generating 13,000 yuan in demurrage.These are all unnecessary hidden expenses.

In 2026,global trade rules change frequently.We will monitor the latest tariff rates and anti-dumping warnings of the country of origin for customers in advance.For example,for grease imported from ASEAN countries,we will verify the RCEP Rules of Origin standards to ensure compliance,so as to enjoy preferential tariff treatment under the agreement,which can save up to half of the tariff costs.For special grease imported from European and American countries,we will also check compliance with the latest REACH regulations in advance to avoid re-export due to non-compliance.

Zhongshitong is headquartered in Shanghai International Trade Center.We provide on-the-ground operation and have the ability to file declarations remotely at ports nationwide.Our global agency network can coordinate handling of overseas space booking and document pre-review,solving information gap in cross-regional customs clearance.Besides compliance,we also help customers control exchange rate risk.With large exchange rate fluctuations in 2026,we can lock the exchange rate based on the payment time of cargo owners to avoid unnecessary exchange losses.

Finally,we give two pitfall-avoidance tips to all cargo owners importing grease: First,conduct HS pre-classification in advance,and verify that brand,model,components,specifications and declaration elements are completely consistent.Do not try to muddle through by taking chances,as the accuracy of customs inspection is much higher than you imagine.Second,send documents to the brokerage for pre-review 10 days in advance.Do not wait until the goods arrive at the port to supplement documents.Demurrage ranges from hundreds to thousands of yuan per day,and it is completely unnecessary to spend such money.
