Subheadings
Products classified under Tariff item 2912.11
Anhydrous Formaldehyde Gas Cylinders
High-purity anhydrous methanal in pressurized cylinders for industrial chemical synthesis. It is a separate chemically defined acyclic aldehyde, meeting Chapter 29 note (a) criteria.
2912.11.00Bulk Formaldehyde Railcar Grade
Commodity-grade 37% formaldehyde shipped by railcar for particleboard manufacturing. This aqueous solution of methanal qualifies under Chapter 29 note (d) as a product dissolved in water.
2912.11.00Formaldehyde 40% Stabilized Solution (Methanol Stabilized)
A 40% formaldehyde solution stabilized with methanol to prevent polymerization, used in resins and adhesives production. The stabilizer is permitted under Chapter 29 note (f) for preservation or transport.
2912.11.00Formaldehyde Diagnostic Grade Solution
Formaldehyde solution certified for clinical chemistry analyzers and diagnostic kits. The diagnostic certification does not change the chemical classification as methanal under Chapter 29 note (a).
2912.11.00Formaldehyde for Plywood Resin Production
Technical grade formaldehyde solution optimized for phenol-formaldehyde plywood adhesives. Formulation specifications do not override the chemical definition of methanal as an acyclic aldehyde.
2912.11.00Formaldehyde for Urea Resin Synthesis
Pharmaceutical/purity grade formaldehyde specifically for pharmaceutical intermediate synthesis. Intended use does not affect classification; it remains a chemically defined methanal compound.
2912.11.00Formaldehyde Semiconductor Processing Grade
Ultra-high purity formaldehyde for photoresist manufacturing in semiconductor production. It is a chemically defined methanal meeting Chapter 29 requirements for electronic chemical intermediates.
2912.11.00Formaldehyde USP Grade 10% Solution
Pharmaceutical-grade 10% formaldehyde solution meeting USP standards for tissue fixation and embalming. It is a chemically defined methanal solution in water, per Chapter 29 note (d).
2912.11.00Formaldehyde with Anticaking Agent
Methanal solution with added anticaking agent for bulk storage stability. This additive is allowed under Chapter 29 note (f) as a stabilizer necessary for preservation or transport, provided it does not make the product suitable for a specific use.
2912.11.00Formalin Tissue Fixative Solution
Buffered 10% formalin solution specifically formulated for histological tissue preservation in medical labs. The buffer does not constitute another oxygen function, so it remains methanal under Chapter 29.
2912.11.00High Purity Formaldehyde 99% Distilled
Distilled high-purity methanal (99%) for specialty chemical synthesis and electronics. It is a separate chemically defined compound meeting strict Chapter 29 purity standards.
2912.11.00Industrial Formaldehyde 50% Solution
High-concentration 50% aqueous formaldehyde for urea-formaldehyde resin manufacturing. It is a methanal solution per Chapter 29 note (d); concentration does not affect classification.
2912.11.00Methanal (Formaldehyde) 37% Aqueous Solution
A 37% aqueous solution of methanal, commonly known as formalin, used as a disinfectant, preservative, and in chemical synthesis. It is a chemically defined acyclic aldehyde without other oxygen functions.
2912.11.00Stabilized Formaldehyde for Textile Finishing
Formaldehyde solution with proprietary stabilizer for durable press textile finishing. The textile application does not override the chemical definition, and the stabilizer is permitted under Chapter 29 note (f).
