Lindane Market Analysis: Demand and Supply Analysis and Sourcing

Lindane is the gamma isomer of hexachlorocyclohexane. It has the molecular formula C6H6Cl6, a molar mass of 290.81 g/mol, and CAS number 58-89-9. It is a white crystalline solid with a melting point of 113 to 115 degree Celsius. It can be sourced from analytical chemical suppliers, Japanese reagent catalogs, European distributors, and reference material suppliers. Purchasing options include annual orders, a backup supplier for each pack size, in-house testing of isomer content, and checks of certificates of analysis. Demand has shifted from crop protection to laboratory reference testing and limited pharmaceutical uses. IHPA records show that about 600,000 tonnes were used between 1950 and 2000, while annual global production reached 3,222 tonnes between 1990 and 1995. In the fourth quarter of 2026, Supelco listed 250 mg at USD 67.20, while Mikromol listed the same quantity at EUR 1,430. TCI listed 250 g at JPY 10,800, excluding tax. Based on the Supelco price, 1 kg would cost USD 268,800.

Lindane is mainly supplied by chemical catalog companies. Supelco offers a PESTANAL analytical standard, TCI sells material with more than 99.0% purity by GC, and Mikromol offers reference material certified under ISO 17034. The Convention register of specific exemptions lists no registered Parties. Supply has declined over time. IARC reports that global production was about 38,000 tonnes in 1986 and lists 13 producers at that time, including seven in India and four in China. IHPA estimated annual production at 1,300 to 2,000 tonnes in its 2006 report, while China maintained output of around 1,000 tonnes per year.

Summary of the Product, Grades, and Uses

Lindane is a white crystalline powder, also known as gamma-BHC, gamma-HCH, and Gammaxene. Its CIPAC code is 488. Its melting point ranges from 113 to 115 degree Celsius according to Supelco and from 112.0 to 115.0 degree Celsius according to TCI. At 20 degree Celsius, its water solubility is 0.0007 g per 100 mL, and its log Pow ranges from 3.61 to 3.72. It dissolves in ethanol, ether, benzene, and chloroform. Lindane contains 24.78% carbon, 2.08% hydrogen, and 73.14% chlorine. Lindane is available in several grades. Technical-grade hexachlorocyclohexane (HCH) contains 60 to 70% alpha isomer and about 14% gamma isomer. Enriched HCH is produced by removing the alpha isomer through crystallization, resulting in a product containing about 40% gamma isomer. Production of this enriched material had stopped in the EU and US by 1979. Material containing at least 99.0% gamma isomer may be sold as lindane. Laboratory and reference grades include analytical standards, ISO 17034 reference materials, and TCI reagents available in 5 g, 25 g, and 250 g packs.

Main End-Uses of Lindane

Agriculture was the largest use of lindane by volume. It was used to treat seeds, control soil insects, and protect fruit, vegetables, forests, and livestock from pests. ICI introduced Mergamma A in 1949 as a seed treatment containing 20% lindane and 1% mercury. US production reached its highest level at 7,983 tonnes in the 1950s. In pharmaceuticals, lindane has been used as a second-choice treatment for head lice and scabies. Morton Grove Pharmaceuticals issued a label for Lindane Lotion USP 1% in August 2007. Its Medication Guide listed permethrin and crotamiton as examples of safer treatment options. Waste isomers from lindane production were also used to make other chemicals. German plants converted about 70,000 tonnes of HCH waste into trichlorobenzene. Ugi Kuhlmann reused waste material to produce 1,2,4-trichlorobenzene and 2,4,5-trichlorophenoxyacetic acid. The third use is in laboratory testing and research. Suppliers such as Supelco, TCI, and Mikromol sell lindane as an analytical standard and reference material.

Lindane Market Risks

Lindane faces strict regulatory controls because Annex A of the Stockholm Convention lists it for elimination. China bans its production, sale, use, import, and export, while India lists it among pesticides banned from manufacture, import, and use. Its health hazards increase safety and handling costs. Supelco lists hazards including toxicity if swallowed or inhaled, harmful effects through skin contact, possible harm to breastfed children, damage from prolonged exposure, and high toxicity to aquatic life. TCI also lists serious hazards, including possible cancer risk and organ damage. IARC classifies lindane as Group 1, meaning it is carcinogenic to humans, based on evidence linking it to lymphoma. Its oral LD50 in rats is 88 mg/kg. Waste disposal creates a major financial burden because each tonne of lindane production can generate 6 to 12 tonnes of other isomers. Aragon spent EUR 54 million over 25 years managing the Inquinosa site and estimated that another EUR 550 million would be needed. Transport classifications also differ between suppliers: Supelco lists UN 2811, while TCI lists UN 2761. Both classify lindane as a Class 6.1 toxic substance with Packing Group III. Estimates of waste generation also vary, with IHPA reporting ratios ranging from 6 to 10, 8 to 12, and 10 to 12 tonnes of waste per tonne of lindane. Access may also be restricted, as Fisher lists Mikromol products as restricted to business accounts.

Lindane Production Process and Main Cost Drivers

The lindane production process runs from benzene and chlorine through photochlorination, benzene recovery, methanol extraction, and crystallization to lindane.

1. By Photochlorination of Benzene and Methanol Extraction of the Gamma Isomer: The main inputs are benzene, chlorine, methanol, ultraviolet light, power & steam.

Lindane production begins with the photochlorination of benzene. In this process, chlorine is dissolved in excess benzene and exposed to strong ultraviolet light in a thin-layer photoreactor. Iron must be kept out of the reactor because it can cause unwanted substitution reactions. The resulting crude hexachlorocyclohexane (HCH) contains about 14% gamma isomer, 65 to 70% alpha isomer, 7 to 10% beta isomer, and around 7% delta isomer. Other methods use high-pressure mercury lamps or calcium oxide as a catalyst, with the reaction temperature rising from about 25 to 35 degree Celsius. Another method uses carbon tetrachloride at 15 degree Celsius. After the reaction, alkali neutralization removes acidic residues. Distillation recovers excess benzene, and the remaining crude HCH is melted to remove impurities before being solidified. The mixture is then cooled to separate the alpha isomer, leaving enriched HCH with about 40% gamma isomer.

The enriched HCH is extracted with methanol at 15 to 25 degree Celsius, and filtration separates the undissolved isomers. Methanol is removed by distillation at 80 to 100 degree Celsius, allowing the gamma isomer to crystallize during cooling. Repeated crystallization produces material with at least 99.0% gamma isomer. Solvents and remaining liquids are recycled, while solvent recovery produces a stream containing the delta isomer. Alpha-isomer residues are filtered and dried before further treatment. At the Inquinosa plant, benzene, chlorine, and ultraviolet light were used in the reaction, while distillation produced lindane and left HCH powder and distillation residues as waste. Waste isomers can be processed in cracking units. One patented method uses zinc in an electrolytic cell at temperatures above 95 degree Celsius to recover benzene and chlorine, reaching 84% and 95% of their theoretical yields, respectively. Other methods convert waste isomers into trichlorobenzene or produce hydrochloric acid through heating. The main factors affecting production costs include gamma-isomer content, extraction recovery, solvent losses, lamp power consumption, chlorine prices, and waste treatment costs.

Main Factors Affecting Lindane Production Cost

Lindane production costs mainly depend on the amount of gamma isomer recovered from technical-grade hexachlorocyclohexane (HCH). Technical HCH contains about 14% gamma isomer, so producing 1 kg of lindane at full recovery requires 7.14 kg of HCH and leaves 6.14 kg of waste isomers. If waste generation reaches 9 kg per kg of lindane, the process uses about 10 kg of HCH and recovers around 71% of the gamma isomer. At 12 kg of waste, it uses about 13 kg of HCH, with recovery falling to around 55%. For each kilogram of HCH, the reaction uses about 0.269 kg of benzene and 0.731 kg of chlorine. Using 10 kg of HCH per kilogram of lindane therefore requires 2.69 kg of benzene and 7.31 kg of chlorine before benzene recycling. Waste treatment adds a major expense. The International HCH and Pesticide Forum estimates cleanup costs of USD 2,000 to 3,000 per tonne of HCH waste. At 9 kg of waste per kilogram of lindane, this equals USD 18 to 27 per kilogram of product. A plant producing 1,000 tonnes of lindane annually would generate 9,000 tonnes of waste, with estimated cleanup costs of USD 18 million to 27 million per year. The beta isomer adds to this burden because it makes up 7 to 10% of technical HCH. Processing 10 kg of HCH produces about 0.7 to 1.0 kg of beta isomer per kilogram of lindane.

Since the beta isomer reacts about 7,000 times more slowly than other isomers during dehydrohalogenation, the required waste-treatment capacity affects costs. Pack size also affects the price of reference-grade lindane. TCI lists 5 g at JPY 2,000, 25 g at JPY 3,000, and 250 g at JPY 10,800, reducing the price per gram from JPY 400 to JPY 43.2. The listed price for 250 mg from Mikromol equals EUR 5,720 per gram, while the Supelco price works out to USD 268,800 per kilogram. Variable costs include benzene, chlorine, methanol, alkali, lamp replacements, and packaging. Utility costs cover lamp power, steam for distillation, cooling water, refrigeration for crystallization, and wastewater treatment. Fixed costs include photoreactors, distillation columns, extraction vessels, crystallizers, filters, dryers, waste-cracking equipment, and laboratory facilities.

Raw Materials for Lindane Production Plant and its Procurement

Raw material sourcing for lindane involves three main groups: benzene and chlorine, solvents, and materials used to treat waste isomers. Benzene and chlorine are the main raw materials by volume. The Inquinosa process diagram lists benzene, chlorine, ultraviolet light, and methanol as process inputs. Benzene is obtained from refinery and steam cracker operations, while chlorine is produced through chlor-alkali electrolysis. Other inputs include alkali for neutralization, methanol, mercury lamps, zinc for certain waste-treatment methods, nitrogen, and packaging drums. Purchasing starts with setting quality requirements for each raw material. Buyers specify benzene purity and limits for water and thiophene, along with moisture limits for chlorine. Iron contamination must also be controlled because it can cause unwanted substitution reactions. Suppliers provide certificates of analysis, safety data sheets, and transport information. Incoming materials are checked for purity using gas chromatography (GC) and for water content using the Karl Fischer method.

Sustainability and Regulatory Requirements

Lindane manufacture raises concerns that center on acute toxicity, persistence, bioaccumulation, aquatic harm, and waste isomers. Supelco lists H410 with M-factors of 10, and a fathead minnow bioconcentration factor of 674. Decision SC-4/15 listed lindane in Annex A in May 2009. The production entry carries zero exemptions, and the use entry allows human health pharmaceutical use against head lice & scabies as second-line treatment. Canada's entry expired on 4 April 2016, Sri Lanka's on 26 August 2015, and Nigeria withdrew on 15 October 2012. Sri Lanka's entry covered an estimated 137 kg.

China prohibits production, distribution, use, import & export under Ministry Announcement 10, effective 26 March. France banned use in 1998, Brazil in 1992, and Germany in 2004. EPA canceled seed uses by 2007, and FDA requires a boxed warning on the pharmaceutical label. Alpha & beta HCH joined Annex A at the same meeting, so waste isomers carry elimination duties too. The last Indian unit left an estimated 36,000 to 54,000 tonnes of HCH waste, and dumpsite soil reached 450 g/kg of total HCH. Basque Country spent about EUR 50 million on landfills, including EUR 8.4 million on base-catalyzed dechlorination, and the Netherlands about EUR 27 million on soil. OSHA sets 0.5 mg/m3 as the permissible exposure limit for lindane. A plant could assess closed transfer, local exhaust, enclosed drying, and dust control against it.

CAPEX and OPEX for a Lindane Production Plant

A lindane plant uses continuous photochlorination, followed by batch purification and a unit for treating waste isomers. The main equipment includes thin-layer photoreactors with high-pressure lamps, chlorine feed systems, benzene storage tanks, and alkali washing equipment. Distillation columns recover excess benzene. The next stages use melters, cooling crystallizers to separate the alpha isomer, methanol extraction vessels, and gamma crystallizers. Filters, a centrifuge, a dryer, and a solvent recovery column complete the purification process. A separate unit treats alpha, beta, and delta isomers. Processes that convert these waste isomers into trichlorobenzene also release hydrochloric acid. One French capacity list reports annual production of 16,400 tonnes of trichlorobenzene alongside 12,000 tonnes of hydrochloric acid. Because lindane is highly toxic, the plant requires closed transfer systems, exhaust gas scrubbers, secure packaging, and locked storage areas. Alpha and beta isomer residues may be kept in covered, lined storage areas with containment barriers. The lindane plant setup cost depends on reactor size, lamp capacity, extraction recovery, and waste-treatment capacity. A laboratory checks isomer content using gas chromatography (GC) and tests melting point, moisture, and residual methanol. Wastewater treatment facilities are also required.

Plant Location and Investment Factors

Suitable sites for a lindane plant would need access to benzene and chlorine supplies, steam, electricity, solvent recovery facilities, and permits for handling toxic solid waste. Site selection also depends on access to chlor-alkali plants, ports and railways, wastewater discharge permits, waste disposal facilities, and proximity to customers who buy reference materials. The main investment decision for a lindane plant is how to manage waste. Parties to the Stockholm Convention must eliminate lindane production, so any proposed operation would need to be assessed under the laws of the relevant jurisdiction. The United States is not a party to the Convention, but other applicable regulations still apply. A waste-cracking unit or an approved disposal contract would determine the cost of handling the large amount of waste generated, estimated at 9 tonnes per tonne of product. Plant scale is another consideration, as public suppliers list pack sizes ranging from 250 mg to 250 g. New businesses could consider contract purification or supplying catalog-grade materials through an established fine chemical company, subject to legal requirements. Investment assessments should cover regulatory permits, waste management contracts, customer audits, and working capital.

Major Lindane Producing Regions

Spain had several documented lindane production sites, including Bilbao Chemical in Barakaldo, Nexana in Erandio, Zeltia in O Porriño, and Inquinosa in Sabiñánigo. In France, Ugine Kuhlmann operated in Huningue, and IHPA reported lindane production capacity of 4,000 tonnes per year in 1990. Germany recorded some of the highest production volumes. Three East German plants produced a total of 18,128 tonnes, while a West German plant produced 16,000 tonnes between 1955 and 1971. In the United States, one site produced 28 million pounds of lindane between 1946 and 1958. In Asia, China produced 11,400 tonnes between 1991 and 2000 and exported 8,200 tonnes. India's largest producer made 619, 520, and 266 tonnes in 2000, 2001, and 2002, respectively, with a daily capacity of 3 tonnes. By 2004, the plant was operating at nearly 5% of its capacity, and production fell to zero during the first nine months. Romania continued producing lindane until 2006, while Brazil produced 98,583 tonnes of HCH between 1962 and 1985. The Netherlands stored at least 5,500 tonnes of HCH in 1954 and shipped about 4,000 tonnes to Germany in 1975. An Indian BHC plant with an annual capacity of 3,000 tonnes stopped production on 1 April 1997 following a government ban.
