What Custom Fiber does

Custom Fiber BV is a Belgian private limited company headquartered in Bornem that manufactures functional fibers derived from natural plant raw materials. Its portfolio spans powdered cellulose, bamboo, sugar cane, wheat, oat, apple, cocoa, and chokeberry fibers, plus application-specific CustomFit Blends, produced in five standardized particle lengths (30, 75, 90, 200, and 500 microns) using proprietary mechanical purification, micronization, and sterilization processes without chemical modification.

The company sells primarily B2B into food manufacturers across bakery, meat, dairy, frozen-food, pasta, sauce, and dressing segments, and into industrial end-uses including construction, filtration, and rubber. Distribution is direct via a sales team supplemented by presence at IFFA, Intrafood, and Fi Europe trade shows. Market access is anchored by a multi-jurisdiction certification stack — BRC, ISO 22000:2018, FDA, KOSHER, and HALAL — which qualifies product into EU, US, Muslim-majority, and kosher-certified end-markets. Minimum order quantities are set at full-pallet volumes, consistent with a mid-market industrial customer base rather than long-tail small buyers.

No funding rounds, headcount, or revenue figures are publicly disclosed. The company self-positions as a "global leader" in fibers derived from nature, with claimed worldwide customer reach, though financial and operational scale cannot be independently verified from public material.

Core offering

Custom Fiber BV manufactures functional, high-quality insoluble fibers derived from natural plant raw materials including cereals, cellulose, vegetables, and fruits, produced through physical processing methods (purification, micronization, and heat-steam sterilization) without chemical additives. The portfolio spans powdered cellulose, bamboo, sugar cane, wheat, oat, apple, cocoa, and chokeberry fibers in five standardized fiber lengths (30-500 microns), plus the proprietary CustomFit Blends line of clean-label ingredient systems for egg/fat/emulsion replacement and structure improvement. Products are sold to food manufacturers (bakery, meat, dairy, frozen/convenience, pasta, fish, vegetarian) and industrial users (construction, filtration, rubber, welding, drilling fluids) globally.

Product overview

Custom Fiber is an international manufacturer specializing in functional, high-quality fibers derived from natural plant materials including cereals, cellulose, vegetables, and fruits. The product portfolio centers on insoluble fiber products across seven core fiber types: Powdered Cellulose (C products), Bamboo Fiber (B products), Sugar Cane Fiber (SC products), Wheat Fiber (W products), Oat Fiber (OB products), Apple Fiber, and Cocoa Fiber (CA products), plus Chokeberry Fiber as a recent addition. All core products are available in five standard fiber lengths (30, 75, 90, 200, and 500 microns). Complementing the core offerings is the Customfit Blends family—a series of specialized high-functional, clean label fiber blends tailored for specific applications including bakery, meat, fruit filling, sauces, gluten-free bread, and breaded products. The company operates in both food (bakery, meat, dairy, frozen/convenience, pasta, fish/surimi, vegetarian, and other) and industrial (construction chemistry, filtration, welding electrodes, thermosets/thermoplastics, artificial leather, rubber, drilling fluid) sectors.

Broad incumbents

• Cargill: Diversified global food-ingredient agribusiness offering fibers, starches, and texturizers to bakery, meat, dairy, and beverage customers. Comparable as a broad supplier of food ingredients including dietary fibers, though fiber is one of many categories for Cargill.
• IFF (formerly DuPont Nutrition & Biosciences): Global ingredient powerhouse with cellulose-based ingredients, cultures, enzymes, and food textures serving bakery, meat, and dairy manufacturers. Comparable in that cellulose-derived functional ingredients are part of its portfolio.
• Ingredion: Major ingredient solutions provider serving food, beverage, and industrial customers with starches, sweeteners, and fiber ingredients. Competes with Custom Fiber in the bakery, dairy, and meat-processing segments where texturizers and clean-label solutions are sold.
• Roquette: Global specialty food and nutrition ingredients company with a portfolio that includes fibers and starch-based texturizers serving bakery, dairy, meat, and confectionery customers. Overlaps with Custom Fiber across food-formulation fiber use cases but operates at significantly larger scale.
• Tate & Lyle: Specialty food and beverage ingredients company with texturizers, sweeteners, and fiber solutions serving bakery, dairy, beverage, and nutrition customers. Overlaps with Custom Fiber in the food-formulation fiber/texturizer category.
• ADM: Global agribusiness with a substantial Nutrition segment offering fibers, flavors, and specialty ingredients to food and beverage manufacturers. Comparable to Custom Fiber in customer base and in providing plant-derived functional food ingredients.

Regional players

• Herbafood Ingredients: German specialty producer of apple and fruit fibers derived from pomace valorization, primarily serving European food manufacturers. Directly comparable to Custom Fiber's Apple Fiber and Chokeberry Fiber pomace-based lines and to its regional European B2B focus.

Direct peers

Closely comparable to Custom Fiber in product type (powdered cellulose, vegetable fibers), target customers (food/industrial formulators), and business model (B2B ingredient supplier with standardized grades).
• SunOpta: Plant-based food and beverage company specializing in plant-based ingredients, fibers, and processed fruits/nuts including insoluble dietary fibers for bakery, beverages, and dairy. Direct overlap with Custom Fiber in plant-based, non-GMO, and clean-label fiber ingredients for food manufacturers.
