FAQ

 

 

 

Q: How is Methyl Ethyl Ketone (MEK) priced in China?

A: The price of Methyl Ethyl Ketone (MEK) in China fluctuates in line with market conditions, and orders are priced separately based on CAS purity grade, purchase quantity, and destination. Costs are primarily influenced by raw materials, energy, and payment terms. Methyl Ethyl Ketone is produced via mature chemical processes and shares the China Shandong industrial cluster. Methyl Ethyl Ketone is one of our main products, and we can provide samples and large volume shipments to Central and Eastern Europe, Ukraine, and other countries and regions worldwide. Inventory can be stored at our partner chemical warehouse in Poland. With self sufficient raw material supply and a short production chain, Methyl Ethyl Ketone offers a price advantage over imported products.

Q: Can I order samples and bulk quantities of Methyl Ethyl Ketone (MEK)?

A: We accept both sample and bulk orders. Sample MOQ is flexible with multiple purity grades, each supplied with COA for R&D and pilot testing. Bulk orders start from metric ton quantities with volume based discounts. Custom packaging and full truck bulk transport are available. We recommend sample validation prior to bulk purchasing to mitigate supply chain risks. Note: hazard classification varies by purity; both hazardous and non hazardous chemicals require SDS & COA, while hazardous goods additionally need UN number, dangerous goods packaging certificate and dangerous goods declaration.

Q: What Compliance Requirements for Exporting Methyl Ethyl Ketone (MEK) to EU and Ukraine?

A: Sales to the EU are subject to REACH regulation. Where the annual import volume is ≥ 1 tonne, registration must be completed via an EU based Only Representative (OR); otherwise the substance cannot be placed on the market. Continuous monitoring of updates to the SVHC Candidate List and control of threshold values for restricted substances are required. The EU also enforces CLP classification, labelling and packaging rules, and SDS must follow the EU GHS format. It is recommended to work with a compliance institute to verify the CAS number and impurity profile and submit the dossier in advance to prevent port detention. Ukraine (UA REACH): Ukraine has implemented UA REACH chemical regulations aligned with EU REACH. For annual import ≥ 1 tonne, local chemical registration in Ukraine is required. Existing EU REACH data may be reused to simplify dossier preparation. UA CLP classification and labelling apply, and Ukrainian language SDS is needed. Additional attention shall be paid to Ukraine customs clearance, tariffs, certificate of origin and special logistics & document requirements under wartime conditions. Methyl Ethyl Ketone is classified as Class 3 flammable dangerous goods under IMDG and is a marine pollutant. A transport condition identification report is required for filing with freight forwarders and shipping lines. Section 14 of SDS clearly indicates the corresponding hazard class and UN number.

Q: Can you provide SDS and COA documents for Methyl Ethyl Ketone (MEK)?

A: Complete 16 section SDS and batch specific COA are available upon request. SDS covers physical chemical properties, hazard classification, first aid, firefighting, spill handling and storage transport requirements for booking, customs clearance and destination country compliance. COA records batch level indicators including purity, water content and acidity for full traceability and comes with sample shipments. EU GHS formatted documents can be arranged with advance notice. To validate SDS authenticity, cross check CAS No., product name, GHS hazard statements and UN number; third party verification is recommended if needed.

Q: How do you deliver Methyl Ethyl Ketone (MEK) to Central Eastern Europe and Ukraine and worldwide?

A: For bulk orders: goods are packed in 155 kg galvanized drums or ISO TANK containers and shipped from Chinese ports to hub ports including Gdańsk (Poland), Hamburg (Germany), Constanța (Romania), then cross border transported by licensed dangerous goods trucks to warehouses in western Ukraine. Full documentation including SDS, COA, dangerous goods packaging certificate and transport appraisal report will be provided for transit country customs clearance. For small batch / sample orders: dangerous goods air freight to Warsaw or Frankfurt, last mile handled by local hazardous goods logistics providers. For Ukraine shipments, we strongly recommend "Poland/Germany + cross border trucking" routing to avoid airspace restrictions. Note: Class 3 flammable liquids require dangerous goods vessel space; acceptance rules vary by shipping line per UN number.

Q: Do you keep Methyl Ethyl Ketone (MEK) stock in Poland?

A: Our partner hazardous goods warehouse in Poland holds regular inventory of industrial grade Methyl Ethyl Ketone. Urgent production orders can be dispatched within EU territory for shortened lead time. For large volume bulk orders, direct shipment from China is arranged to optimize total procurement cost.

Q: What are your typical lead times and production capacity for Methyl Ethyl Ketone (MEK)?

A: Industrial grade Methyl Ethyl Ketone samples are in stock and dispatched within several working days upon sample confirmation. For bulk orders, exact production & delivery timeline will be confirmed after receiving order quantity, packaging requirement and destination. Supported by Shandong chemical cluster supply chain, we maintain flexible scheduling for regular monthly orders and urgent replenishment requests. Submit your inquiry for confirmed lead time aligned with your project timeline; we will reply within 1 working day.
