The purchasing party is BARPLAS S.L., a new materials enterprise headquartered in Barcelona, Spain. As a leading mid-to-high-end modified nylon producer in Western Europe, it specializes in glass fiber reinforced PA66 for new energy vehicle engine compartments, food-contact nylon kitchenware substrates, and high-end nylon spinning raw materials, supplying Spanish SEAT and French Roquette food supply chains. Raw material access complies with EU REACH, EU 10/2011 food-contact regulations, and automotive VOC control standards. The company has exclusively adopted original BASF Irganox 1098 for over a decade, with an annual 1098 procurement volume of 176 tons.
Driven by surging European chemical raw material prices and extended lead times exceeding 75 days for overseas major manufacturers, the client launched a localization substitution project structured in three phases: 50kg sample evaluation → 3-ton pilot production → full annual mass procurement. The client independently contacted five top domestic antioxidant manufacturers (Lianlong, Yingkou Fengguang, Shandong Sanfeng, Jiangsu Shengnuo, Jinneng) to request technical documents and samples, yet encountered clear barriers to grade selection:
1. All manufacturers exclusively promote their own products and avoid objective discussion of competitor strengths: All five enterprises operate in compliance without maliciously disparaging peers, yet sales teams only highlight their own brand specifications, production capacity, and pricing, refusing to comment on competing brands’ advantages, applicable scenarios, and weaknesses. For example, Lianlong only emphasizes low discoloration performance of RIANOX 1098 without mentioning the low residual solvent strengths of Fengguang refined grades; Fengguang only highlights high purity while ignoring the superior dispersion performance of Shengnuo spinning-specific grades.
2. The client lacks a domestic grade database and cannot distinguish general-grade / refined-grade / spinning-specialized grades: Multiple distinct product sub-grades share the identical "1098" product name with similar national standard indicators, yet exhibit drastic divergence in free intermediate content, residual solvents, and particle size. The Spanish R&D team relies on BASF-grade selection logic and cannot benchmark domestic variants. Blind testing of general-grade samples from all five manufacturers triggered extrusion blooming, spinning filament breakage, and thermal aging yellowing across three batches, consuming two months of testing without identifying compatible grades and halting the localization project. Recommended by the Spanish Plastics Industry Association, the client fully entrusted HiSiaddi – equipped with additive technical grade selection teams and multi-brand actual testing databases – to conduct horizontal evaluation of domestic 1098 variants, grade screening, and sample coordination.
HiSiaddi technical specialists compiled official COA documents, third-party test reports, and downstream modification application cases from all five brands, objectively dissecting strengths and weaknesses of mainstream models across three core client application segments: automotive modification, food-grade nylon, and nylon spinning. The five brands analyzed: Tianjin Lianlong, Yingkou Fengguang, Shandong Sanfeng, Jiangsu Shengnuo, Jinneng.
Mainstream variants: RIANOX 1098 General Refined Grade, RIANOX 1098-F Food-Grade Refined Strengths: Top listed domestic manufacturer with optimal batch consistency; product transmittance ≥97% at 425nm, superior low discoloration performance with minimal yellowing after long-term thermal aging, ideal for automotive modified nylon. Globally supplies multiple European modification manufacturers with complete REACH pre-registration and stable continuous mass production without stockout risks. Weaknesses: General-grade variant contains ~280ppm free intermediates, unsuitable for ultra-high-standard food substrates; food customized grade carries higher unit pricing.

Mainstream variants: FGL-1098 National Standard Premium Grade, FGL-1098-H High-Purity Refined Grade Strengths: Long-established domestic antioxidant production base. FGL-1098-H adopts dual recrystallization processes with free intermediates ≤110ppm and total residual solvents <8ppm, impurity control matching original BASF standards, excellent anti-precipitation and solvent extraction resistance, highly compatible with food-grade nylon. Weaknesses: Extended production lead times for high-purity refined grades, low sample stocking efficiency for small-batch orders; standard national grade generates heavy dust, unsuitable for precision spinning applications.
Single flagship variant: SF-1098 Industrial Refined Grade Strengths: Moderate cost-performance ratio, uniform low-dust particles with favorable melt dispersion, compatible with standard glass fiber modified nylon, abundant in-stock inventory with short lead times. Weaknesses: Elevated thermal weight loss at 280°C (0.68%), insufficient long-term heat resistance failing long-term aging requirements for high-temperature engine compartment nylon; disqualified for food-contact substrates.
Flagship variant: Sinanox 1098-S Spinning-Specialized Refined Grade Strengths: Granulation process optimized exclusively for nylon spinning with uniform ultrafine particles free of agglomeration, superior dispersion speed eliminating localized additive enrichment and resolving spinning filament breakage defects. Moderately above-average residual solvent control. Weaknesses: Suboptimal cost-performance ratio for general modified nylon applications; no food-grade compliant variants available for food-contact nylon production lines.
Flagship variant: JN-1098 National Standard General Grade Strengths: Lowest pricing with abundant in-stock inventory, compatible with low-end general modified plastics. Weaknesses: Free intermediates exceed 500ppm with excessive residual solvents, failing EU food and automotive VOC standards.
The client operates three production lines with segmented demand: ① 60% production capacity for automotive PA66 engine compartment modification; ② 25% capacity for food-contact nylon kitchenware pellets; ③ 15% capacity for polyamide spinning raw materials. HiSiaddi eliminated Shandong Sanfeng and Jinneng variants (only suitable for low-end general materials), finalizing two mid-to-high-end brands and three precision-matched variants:
1. RIANOX 1098 Standard Refined Grade: Deployed exclusively on the client’s glass fiber reinforced automotive PA66 modification line, leveraging low discoloration and stable batch performance to meet long-term thermal aging requirements for engine compartment components, replacing standard BASF 1098.
2. RIANOX1098-F Food Refined Grade: Deployed exclusively on food-contact nylon kitchenware production lines, with complete EU 10/2011 migration testing and REACH-SVHC reports satisfying European kitchenware raw material access specifications.
FGL-1098-H High-Purity Refined Grade: Deployed exclusively on polyamide spinning production lines, delivering low impurities, low residual solvents, and anti-precipitation performance to resolve prior filament breakage and blooming defects observed with domestic samples, with impurity indicators nearly equivalent to original BASF materials.
1. Sample Phase (10 Days): HiSiaddi coordinated both manufacturers to prepare 5kg sealed samples of each variant, bundled with bilingual Chinese-English COA and compliance documents for unified airfreight to Spain, eliminating communication overhead from separate client outreach to multiple factories. The client’s laboratory small trials validated all three variants on their respective production lines: modified pellets free of blooming, continuous spinning without filament breakage, full compliance for food migration testing, and thermal aging performance matching original BASF materials.
2. Pilot Production Phase: The client placed a 3-ton split trial order (2 tons Lianlong, 1 ton Fengguang). HiSiaddi coordinated manufacturers to produce 25kg food-grade inner-lined fiber drums customized to European export standards with Spanish-English bilingual GHS labels, paired with bilingual SDS documents. Full-container shipment departed Shanghai Port with smooth Spanish customs clearance. Full production across all lines with the 3-ton pilot batch maintained 99.2% yield rates, cutting procurement costs by 28.5% versus original BASF materials.
3. Annual Long-Term Agreement Execution: Following successful pilot acceptance, the Spanish client finalized an annual 168-ton long-term procurement framework with monthly balanced orders, with purchasing volumes allocated proportionally across the three variants based on production line capacity. All raw material grade selection for the client’s new specialty nylon R&D projects will be fully entrusted to HiSiaddi for horizontal domestic variant evaluation moving forward.
1. Standard Domestic Additive Industry Sales Logic: Prioritize Own Product Sales, Lack Objective Competitor Knowledge Sharing Domestic antioxidant manufacturers center sales strategies on depleting internal production capacity, with industry norms discouraging active promotion of peer product strengths. Mid-to-high-end overseas clients lack internal databases of domestic product variants, frequently selecting mismatched grades and incurring substantial sample testing costs.
2. Core Selection Demand of Mid-to-High-End Overseas Clients ≠ Low Pricing The Spanish client prioritized indicator matching, complete compliance documentation, dedicated grade segmentation for distinct production lines, and consistent batch performance. Low-cost national standard 1098 variants were eliminated outright despite low pricing due to failure to pass EU regulatory and end-product performance testing – a clear distinction from low-volume traders who only prioritize in-stock low pricing.
3. HiSiaddi’s Core Value: Neutral Third-Party Technology-Focused Foreign Trade Grade Selection Operating independent of exclusive agency ties to single manufacturers, HiSiaddi evaluates raw materials objectively based on client end-formulation and regulatory requirements, conducting horizontal cross-brand comparisons to precisely segment specialized sub-grades. This service eliminates non-compliant variants, shortens grade selection cycles, and secures long-term repeat orders via neutral, professional grade selection support.
