Purchaser: ITALPLAST MED SRL (Italplast Medical Plastics Co., Ltd., Italy), located in an industrial park on the outskirts of Milan, Italy. With 28 years of experience manufacturing transparent medical PVC hoses, food-contact plastic packaging films and medical blister sheets, its products are supplied in bulk to top tertiary hospitals in Italy, the packaging division of Nestlé Food and multiple listed EU medical device enterprises. The full production line adopts lead-free eco-friendly calcium-zinc stabilization systems, with long-term fixed procurement of original high-purity dibenzoylmethane (DBM) from Eastman (USA) as auxiliary heat stabilizer, and a stable annual procurement volume of 47 tons. It is a mid-to-high-end raw material purchaser with strict standards for purity, chromaticity, solvent residue, powder particle size and compliance certificates.
Driven by continuous price hikes of local European and American chemical raw materials, contracted production capacity shrinkage of overseas major manufacturers and ocean transportation lead times extended to over 90 days, the client launched a domestic DBM localization substitution project to select qualified formal domestic brands for phased full replacement of imported raw materials. To fully survey domestic supply sources, the client independently contacted five mainstream domestic DBM manufacturers including Anhui Jiaxian, Shandong Jianbang, Nantong Defa, Hubei Yuanmeng and Jiangsu Bosite to request sample delivery, product parameter sheets and quotations. However, the sourcing work stalled for nearly 40 days due to inherent sales drawbacks in the industry: sales representatives from all five manufacturers only promoted their own product advantages. Though they did not slander competitors maliciously, constrained by corporate sales targets, they all avoided objective explanations of competitive brands’ strengths, applicable scenarios and grade characteristics. Each manufacturer only claimed its own grades fit all scenarios without distinguishing general industrial grades and high-end refined grades.
The client lacked awareness of brand tiering in China’s additive industry, receiving 8 DBM samples across five brands with uneven purity, powder whiteness, particle size and solvent residue indicators. Small laboratory tests by the client revealed inconsistent defects including poor mixing dispersion agglomeration, variable product yellowing after aging and fluctuating precipitation during high-temperature boiling for partial samples. Existing information could not support screening of products matching its dual medical + food-contact formulas, nor distinguish low-end industrial general materials and mid-to-high-end refined materials. Finally, the client fully entrusted foreign trade service provider HiSiaddi to conduct horizontal breakdown of full-series products from the five brands as an impartial third party and complete product selection matching its production conditions.
Combining the client’s dual formulas for transparent medical PVC and food-contact packaging with high requirements of low yellowing, low solvent residue, ultrafine particle size and REACH+LFGB compliance, HiSiaddi project engineers sorted out product positioning, main grades, core advantages and applicable shortcomings of each manufacturer one by one to form a complete horizontal comparison file, truthfully recording core strengths of each brand:
Main Grades: DBM-83 national standard general industrial grade, DBM-HP high-purity refined medical grade Product Advantages: Large-scale continuous synthesis production lines with top global annual output and industry-leading batch stability. HP refined grade adopts multi-stage recrystallization process with GC purity≥99.85%, complete EU REACH registration support, excellent solvent residue control and compliance with food & medical standards. Self-owned ultrafine grinding production lines support customized fine particle size powder on demand, with stable large-volume long-term exports to mid-to-high-end European and American markets. Shortcomings: High pricing for high-purity HP grades; conventional DBM-83 industrial grade has coarse grains and high trace colored impurities, only suitable for ordinary PVC pipes and profiles, not applicable to high-end transparent medical substrates.
Main Grades: JB-DBM general grade, JB-DBM-F ultrafine modified refined grade Product Advantages: Mature synthesis process with optimized internal raw material cost control and outstanding cost performance of conventional grades. Exclusive powder looseness improvement technology for ultrafine F grades enabling fast wetting rate during mixing, with prominent adaptability in soft PVC film sectors. Strong domestic supporting R&D capacity for compound heat stabilizers allowing fine-tuning of product indicators matching downstream formulas. Shortcomings: Limited production capacity of high-end refined grades with long scheduling cycles for large-volume orders; less complete supporting services for food-grade compliance testing compared to Jiaxian.
Main Grades: HiSiaddi-83 refined DBM, HiSiaddi-83T modified special grade Product Advantages: Outstanding flexible small-batch customization capacity enabling targeted optimization of crystallization processes for special modified PVC formulas; excellent control of free impurities with flexible response to small-batch special customization requests. Shortcomings: Small overall mass production scale with insufficient supply capacity for ten-thousand-ton level bulk orders; high raw material costs unsuitable for the client’s regular annual procurement of dozens of tons.
Main Grade: YM-DBM national standard industrial grade Product Advantages: Obvious cost advantages for general-grade DBM with flexible supply and sufficient spot inventory, suitable for low-end PVC materials such as ordinary building materials and electric wires & cables, widely adopted by small and medium domestic profile manufacturers. Shortcomings: No mid-to-high-end refined product lines for medical applications; maximum product purity capped at 99.2% with solvent residue generally above 180 ppm and pale yellow chromaticity, failing to pass EU LFGB food-contact migration tests and meet the client’s medical formula access thresholds.
Main Grade: BST-DBM general refined grade Product Advantages: Moderate cost performance of mid-range refined products optimized for domestic civil packaging PVC formulas with acceptable powder processing stability and fast short-distance spot delivery. Shortcomings: Lack of supporting compliance capacity without REACH registration or authoritative third-party food-contact test reports; product indicators fall between industrial materials and high-end refined grades with poor resistance to precipitation during high-temperature boiling tests, incompatible with strict EU regulations.
Combining two differentiated formulas for medical infusion hoses and transparent food packaging films, Hubei Yuanmeng’s pure industrial grades, Jiangsu Bosite’s non-compliant products and Nantong Defa’s grades limited by bulk supply capacity were directly eliminated. Two leading domestic mid-to-high-end brands – Anhui Jiaxian and Shandong Jianbang – were finalized with three targeted sub-grades screened to match different product lines of the client respectively:
1. Anhui Jiaxian DBM-HP (Standard High-purity Refined Grade) Matching Scenario: Conventional mass production formula of the client’s medical PVC infusion catheters. GC purity≥99.86% with minimal batch fluctuation, complete REACH registration and attached LFGB third-party test reports. All basic indicators benchmark the base grade of original Eastman DBM, balancing stability and procurement costs as the primary mass production raw material.
2. Shandong Jianbang JB-DBM-F (Ultrafine Powder Modified Refined Grade) Matching Scenario: Special formula for ultra-thin food-grade transparent packaging films of the client. Exclusive low-temperature grinding process with powder D50≤3.7 μm and excellent dispersion speed, resolving agglomeration and precipitation white spot issues during mixing of thin films, suitable for high-transparency food packaging systems.
3. Anhui Jiaxian Custom DBM-HP-S (Low-residue Modified Special Grade) Matching Scenario: Special formula for high-end medical PVC blister sheets. Optimized negative pressure solvent removal procedures on the high-purity HP base with total solvent residue ≤38 ppm, perfectly meeting strict inspection standards of no precipitation after 95°C high-temperature boiling and complying with EU migration limits for medical raw materials.
1. Parallel small-batch testing by formula system HiSiaddi coordinated free sample delivery of the three selected grades from the two manufacturers. Three groups of samples for medical catheters, food films and medical sheets were formulated separately following the client’s original imported raw material formula. The client’s laboratory conducted three key tests item by item: light transmittance, 72-hour accelerated aging yellowing and precipitation after high-temperature boiling. All three products matched the formulas fully compliant, with finished product whiteness and thermal stabilization performance nearly identical to original Eastman products without yellowing, precipitation or poor dispersion defects.
2. Launch of small-batch pilot procurement The client issued an initial trial order: 15 tons Jiaxian DBM-HP, 8 tons Jianbang JB-DBM-F and 6 tons customized Jiaxian HP-S, totaling 29 tons shipped to Italy in two batches. Goods were accompanied by full English SDS, CLP compliant labels and complete REACH & food-contact compliance documents sorted by HiSiaddi for smooth customs clearance and warehousing.
3. Finalization of annual framework agreement After one month of continuous full-line mass production with fully compliant finished products passing incoming quality inspections of downstream brand owners, the client formally signed an annual procurement framework for 47 tons split into monthly production and delivery batches.
1. Optimization of raw material procurement costs Comprehensive procurement costs of the three domestic mid-to-high-end grades decreased by 26.8% compared with imported Eastman raw materials, drastically reducing annual capital occupation for raw material purchasing while shortening goods arrival cycles from 90 days to around 35 days.
2. Long-term entrusted full-category raw material selection management All subsequent new product R&D and additive substitution of the client were entrusted to HiSiaddi for impartial brand selection evaluation, eliminating risks of wrong sourcing caused by sales-oriented information when contacting manufacturers individually.
3. Upgrading of upstream manufacturer products & expansion of overseas clients Relying on measured application data from this high-end Italian client, Jiaxian and Jianbang refined parameter standards of the three corresponding grades. Supported by HiSiaddi, two additional mid-to-high-end medical plastic end clients in Spain and Greece were developed, continuously expanding overseas mid-to-high-end European market sales channels.
1. Domestic DBM products are clearly divided into three tiers: low-end general industrial materials, mid-range refined materials and mid-to-high-end medical & food-grade refined materials. Constrained by sales performance targets, sales teams of all manufacturers only promote their own products and deliberately avoid explaining competitive brands’ advantages. Lacking accumulated knowledge of China’s chemical market, overseas mid-to-high-end medical clients easily mistakenly select low-end industrial grades when contacting manufacturers one by one independently, leading to formula scrapping and production line debugging losses.
2. The core service value of HiSiaddi lies in breaking away from single-brand sales thinking, conducting horizontal inventory of strengths and weaknesses of all leading industry brands as an impartial third party, and accurately splitting grades aligned with the client’s end formulas and EU compliance requirements to avoid sourcing errors at the source, bridging information barriers between overseas high-end clients and multiple domestic brands.
3. For mid-to-high-end chemical procurement targeting European medical and food sectors, besides product quality, the capacity of service providers to conduct impartial brand selection research and maintain full-category horizontal product reserves constitutes the core competitive advantage distinguishing them from factory sales representatives and ordinary spot intermediaries.
