On 4 November 2026, Mykolaiv Water Utility Company of Ukraine issued a public tender notice with the tender reference number UA-2026-11-04-000590-a. This tender covers the procurement of two types of basic organic chemical raw materials: isopropanol and industrial oxalic acid, to be used for the enterprise's water supply operation and maintenance, laboratory testing, and equipment maintenance. The bid submission deadline is 10:00, Kyiv time, on 20 November 2026.
Isopropanol for laboratory cleaning and disinfection, oxalic acid for descaling and cleaning of water supply equipment.
- To meet the anti‑corrosion and descaling performance requirements for precision instruments of the Ukrainian water utility, isopropanol shall comply with the following key specifications: purity ≥99.7%, density 0.785 g/cm³, acidity 0.0007%–0.001%. For oxalic acid, intended for descaling, derusting, cleaning and maintenance of water supply equipment, heat exchangers and pipelines, the quality criteria are: purity ≥99.5%, molecular weight 90.0–90.05 g/mol and density 1.65 g/cm³.
- The propylene hydration route for isopropanol yields high‑purity product with low equipment corrosion. The acetone hydrogenation route features lower energy consumption and milder corrosion, yet it relies heavily on acetone feedstock; its cost advantage disappears once acetone trades at a premium to isopropanol. For oxalic acid, the CO coupling process delivers outstanding energy saving, emission reduction and economic benefits, with carbon intensity as low as 1.48 tCO₂/t for a low carbon footprint. The coal‑based dimethyl oxalate hydrolysis route offers low cost and high yield, though it faces tightening environmental regulations.
- We can supply premium products conforming to the above specifications. We maintain robust, resilient and stable supply channels, with complete TDS, SDS and COA documentation available for review by your technical team.
Delivery lead time: Goods to be delivered to Mykolaiv warehouse within 10 calendar days upon receipt of the purchase order.
Shipments can be dispatched directly from our bonded warehouse in Poland to Odessa Port, Ukraine. Goods are pre-stored in an ADR-certified hazardous chemicals warehouse and transported by ADR-compliant fleets to mitigate delivery disruptions caused by road closures, security detentions, vehicle breakdowns, embargoes and other force majeure events. Delivery can be completed within 10 calendar days upon order confirmation.
Evaluation Criteria: Price Weight: 100%
- Chinese isopropanol and oxalic acid enjoy distinct price competitiveness in the Ukrainian market: China's isopropanol is priced among the lowest among major suppliers, while Chinese oxalic acid accounts for 99% of Ukraine's imports.
- In 2025, isopropanol was exported to Ukraine by 16 countries. China ranked among the top five with a relatively low average export price of USD 993.2/tonne, 17.9% below the weighted average of USD 1,210.0/tonne across all 16 suppliers. The top five suppliers were the Netherlands, Poland, Germany, Turkey and China, with average prices of USD 1,124.4, 1,372.4, 1,398.7, 1,017.7 and 993.2/tonne respectively. China's price was 2.4% lower than Turkey's, 11.7% lower than the Netherlands', 27.6% lower than Poland's and 29.0% lower than Germany's.
- For oxalic acid, China was Ukraine's primary supplier in 2025, supplying approximately 103 tonnes at an average export price of USD 425.9/tonne (HS 291711). According to mirror data from UN Comtrade, only China and Belgium exported oxalic acid to Ukraine that year. Belgium reported a shipment of merely 7 kg; this volume is negligible with an unrepresentative unit price and is not comparable.
Qualification Requirement: Proof of similar project references
- Isopropanol for laboratory instrument cleaning: China boasts an annual capacity of 940,000 tonnes, roughly one‑quarter of global capacity, with annual exports of 146,000 tonnes, also around one‑quarter of global trade volume.
- Oxalic acid for rust removal: China's annual capacity reaches 1,000,000 tonnes, over 80% of the global total; annual exports stand at 270,000 tonnes, approximately 60% of global trade.
- We maintain partnerships with domestic manufacturers: our isopropanol suppliers are Kailing Chemical (≈ 270,000 t/year) and Hengli Petrochemical (≈ 160,000 t/year); our oxalic acid suppliers are Hualu Hengsheng (≈ 700,000 t/year) and Fengyuan Co., Ltd. (≈ 100,000 t/year). We are fully able to provide performance certificates for similar recent projects.
Payment: Due within 20 calendar days upon delivery acceptance and receipt of invoice.
- Our Polish entity, 7DCHEM Sp. z o.o., accepts settlement in Euro (EUR) via telegraphic transfer (T/T), and will issue compliant invoices and commercial invoices. The buyer may settle the full payment within 20 calendar days.
- Goods are exported directly from our Polish bonded warehouse to Ukraine and delivered to the warehouse in Mykolaiv, eliminating cumbersome Polish customs clearance procedures and VAT, thus reducing capital costs.
FAQ
Q: Is agency authorization available for the Central and Eastern Europe region for us to act as distributor for isopropanol and oxalic acid?
A: Yes, regional agency cooperation for Central and Eastern Europe is available. Leveraging our dual‑warehouse facilities in Central and Eastern Europe, full set of EU compliance documents and a distribution network covering the whole of Central and Eastern Europe, we can support the agency business with stock preparation, complete compliance paperwork, local warehousing and regional delivery services. Further discussions can be held to finalize the detailed terms of the agency partnership.
Q: How do you determine whether a supplier's production capacity is qualified?
A: We verify plant scale and actual output through on-site factory audits, request performance contracts, technical specifications and annual production value, and check production licenses and business licenses to confirm the years of operation. Each supplier is rigorously screened one by one according to the customer's selection criteria, so as to ensure delivery and high-quality customer service through guaranteed capacity.
Q: How do you guarantee after-sales service?
A: We rely on pre-event prevention, not post-event compensation. Our Seven-Dimensional Pre-Control Guarantee System covers supplier screening, capacity verification, technical equivalence confirmation, parameter locking, batch consistency control, documentation management, and shipment tracking - with all steps completed before shipment. Retained samples allow us to resolve any issue within 24 hours.
