Products classified under HTS 2905.11.20.15
Industrial Methanol for Wastewater Treatment
High-purity methanol classified under HTS 2905.11.20.15 specifically for use in wastewater treatment processes such as chemical precipitation and biological treatment enhancement. This saturated monohydric acyclic alcohol meets chapter 29 requirements for separate chemically defined organic compounds used in industrial applications. Its classification reflects its designated end-use in municipal and industrial water purification systems.
Purified Methanol CH3OH Wastewater Grade
Pharmaceutical-grade methanol (CH3OH) meeting ACS specifications for wastewater treatment applications including solvent extraction and microbial metabolism support. This product qualifies under chapter 29 note (a) as a separate chemically defined organic compound with designated wastewater treatment end-use. Purity exceeds 99.8% to ensure effective treatment without introducing contaminants.
Methanol Denatured for BOD Reduction
Specially denatured methanol formulated for biochemical oxygen demand (BOD) reduction in wastewater treatment plants, classified under HTS 2905.11.20.15. This product serves as a carbon source for denitrifying bacteria while meeting chapter 29 purity standards for acyclic saturated monohydric alcohols. Denaturants ensure compliance with industrial use restrictions.
Technical Grade Methanol for Denitrification
Technical grade methanol (99.5% purity) specifically imported for denitrification processes in activated sludge wastewater treatment systems under HTS 2905.11.20.15. Functions as electron donor for nitrate-reducing bacteria while complying with chapter 29 requirements for chemically defined acyclic alcohols. Supplied in bulk for industrial dosing systems.
ACS Reagent Methanol Wastewater Specification
American Chemical Society (ACS) reagent grade methanol meeting stringent purity requirements for wastewater treatment analytics and processes under HTS 2905.11.20.15. Used for both treatment chemical dosing and laboratory analysis of treatment efficacy in compliance with chapter 29 organic compound definitions. Low residue content prevents secondary contamination.
Bulk Methanol for Anaerobic Digestion
Bulk tanker quantities of methanol designated for volatile fatty acid production enhancement in anaerobic wastewater digestion under HTS 2905.11.20.15. This saturated acyclic alcohol serves as co-substrate in biogas production systems meeting chapter 29 chemical definition standards. Supplied in railcar quantities for large municipal facilities.
Methanol for Phosphorus Precipitation
Specialty methanol used as precipitant aid in chemical phosphorus removal from wastewater under HTS 2905.11.20.15. Enhances metal salt precipitation efficiency in tertiary treatment while qualifying as chemically defined acyclic alcohol per chapter 29. Supplied with low metal impurities to prevent interference.
Wastewater Methanol with Stabilizer
Methanol containing polymerization inhibitor stabilizer for extended storage in wastewater treatment applications under HTS 2905.11.20.15, per chapter 29 note (f). Prevents aldehyde formation during bulk storage while maintaining chemical precipitation efficacy. Stabilizer addition justified for transport and preservation needs.
