Tiger-Sul Products

What Tiger-Sul Products does

Tiger-Sul Products is a North American manufacturer of sulphur bentonite fertilizers and micronutrient-enhanced sulphur crop performance products, founded in 1964 and operating as a private subsidiary of Tessenderlo Kerley Inc., the agricultural business unit of Belgium-based Tessenderlo Group (Euronext: TESB). The company manufactures in three facilities — Atmore, Alabama; Stockton, California; and Irricana, Alberta — and runs agronomic R&D at the Tessenderlo Kerley Research Farm and Learning Center in Dinuba, California. Its core technology is a proprietary sulphur bentonite pastille process that combines bentonite clay with elemental sulphur, producing uniformly sized pastilles that absorb moisture, swell, fracture into progressively smaller particles, and oxidize to release plant-available sulphate throughout the growing season.

The product portfolio spans four lines: (1) sulphur bentonite fertilizers including Tiger XP (with proprietary activator), Tiger 90CR, Tiger 85CR, Tiger 50CR (dual-release with ammonium sulphate), Tiger Combo (Canada-only), and Tiger HumiK (jointly developed with HGS BioScience using humic/fulvic acids from leonardite); (2) a full OMRI-listed organic line mirroring the conventional SKUs; (3) micronutrient formulations combining sulphur with zinc, manganese, iron, or copper; and (4) crop-specific mixes such as Tiger Corn Mix II plus industrial-grade sulphur pastilles. Tiger-Sul documents crop yield gains across multi-year trial programs (142 corn trials over 8 years, 89 soybean trials over 6 years, 84 cotton trials over 5 years, 4-year potato trials) to substantiate agronomic claims.

Revenue is generated through one-time sales of physical fertilizer product via a direct field sales force organized into eight North American territories, a regional agronomy team, and, since November 2024, distribution through parent Tessenderlo Kerley's expanded network. Customer segments include row crop growers (corn, soybeans, cotton, wheat), specialty crop growers (potatoes, vegetables), OMRI-organic-certified farms, industrial buyers of sulphur pastilles, and golf/turf management operators. Pricing is quote-based and not publicly disclosed. Standalone financials are not reported; Tiger-Sul sits within Tessenderlo Group, which posted €2.9 billion consolidated revenue in 2023.

Core offering

Tiger-Sul Products manufactures and sells sulphur bentonite fertilizers, micronutrient-enhanced sulphur products (zinc, iron, manganese, copper), crop-specific mixes, and industrial-grade elemental sulphur pastilles for agricultural and industrial applications. The company's proprietary pastille technology combines bentonite clay with elemental sulphur to deliver season-long sulphate availability, with products ranging from conventional fertilizers to OMRI-listed organic certified options for row crops, specialty crops, and turf management.

Product overview

Tiger-Sul Products is a global leader in sulphur bentonite and micronutrient-enhanced sulphur solutions for agriculture. The product portfolio is organized into four main categories: (1) Sulphur Bentonite products including Tiger XP (with activator), Tiger 90CR (90% sulphur), Tiger 85CR (85% sulphur), Tiger 50CR (with AMS), Tiger Combo (Canada only), and Tiger HumiK (with humic/fulvic acid); (2) Organic product line featuring OMRI-listed versions of Tiger 90CR, Tiger 85CR, and micronutrient products (Copper, Manganese, Zinc, Iron) plus Industrial Grade Sulphur Pastilles; (3) Micronutrient fertilizers including Tiger Copper 12%, Tiger Iron 22%, Tiger Manga-Sul 5%, Tiger Manganese 15%, and Tiger Zinc 18%; (4) Crop-specific mixes like Tiger Corn Mix II with Sulphur, Zinc, and Boron; and (5) Industrial Grade Sulphur Pastilles for non-agricultural applications. All products leverage bentonite clay combined with elemental sulphur to create a tiered release pattern that supplies sulphate throughout the growing season.

Broad incumbents

• OCI Global: Global nitrogen and specialty fertilizer producer whose sulphur-bearing products (e.g., ammonium sulphate) target overlapping agricultural end markets with Tiger-Sul.
• ICL Group: Specialty fertilizer producer with sulphur-bearing and micronutrient product lines serving row and specialty crops globally. Comparable as a broad incumbent focused on specialty plant nutrition rather than commodity N-P-K.
• Yara International: Global nitrogen and specialty fertilizer leader producing sulphate-containing fertilizers (e.g., ammonium sulphate) and sulphur-enhanced products that overlap with Tiger-Sul's row-crop and specialty-crop offerings.
• Nutrien: World's largest crop input provider with a full N-P-K and micronutrient portfolio distributed through North American ag retailers that also stock Tiger-Sul products. Competes broadly for the same grower's fertilizer dollar, though it does not specialize in sulphur bentonite pastilles.
• CF Industries: Largest North American nitrogen fertilizer producer whose ammonium sulphate and related sulphur-bearing products compete for the same corn/soy grower as Tiger-Sul.
• The Mosaic Company: Global phosphate and potash leader whose MicroEssentials sulphur-enhanced phosphate products directly contest Tiger-Sul in sulphur fortification of row-crop fertility programs.
• Koch Fertilizer: Major North American producer and distributor of nitrogen, phosphate, and sulphur-containing fertilizers with deep ag-retail reach that overlaps Tiger-Sul's row-crop customer base.
• K+S: European potash and salt producer with a growing specialty fertilizer business (including sulphate-based products) addressing similar crop nutrition needs to Tiger-Sul's specialty and organic lines.

Direct peers

• Compass Minerals: Produces sulphate of potash (K-Mag, Protassium+) and other sulphur-bearing specialty fertilizers for row and specialty crops. Comparable mid-cap specialty fertilizer platform with sulphur-based plant nutrition offerings serving similar North American growers.
• Tessenderlo Kerley: Sister operating company under Tessenderlo Group that produces sulphur-based fertilizers (including Thio-Sul) and distributes Tiger-Sul products through its US ag-input network. Direct overlap in sulphur fertilizer technology and customer base makes it the closest comparable peer.
