Subheadings
Products classified under Tariff item 2912.11.00
Anhydrous Formaldehyde Gas Cylinders
>- High-purity anhydrous methanal (formaldehyde) in pressurized cylinders for industrial chemical synthesis. It is a separate chemically defined acyclic aldehyde without other oxygen functions, meeting the criteria of Chapter 29 Note 1(a) for classification under this tariff item.
Bulk Formaldehyde Railcar Grade
>- Commodity-grade 37% formaldehyde solution shipped by railcar for particleboard manufacturing. This aqueous solution of methanal is a chemically defined compound dissolved in water, as described in Chapter 29 Note 1(d), and falls under this tariff item.
Formaldehyde 40% Stabilized Solution (Methanol Stabilized)
>- 40% formaldehyde solution stabilized with methanol to prevent polymerization, used in resins and adhesives production. The methanol stabilizer is permitted under Chapter 29 Note 1(f) as necessary for preservation or transport, and the product remains classified as methanal under this tariff item.
Formaldehyde Diagnostic Grade Solution
>- Formaldehyde solution certified for clinical chemistry analyzers and diagnostic kits. As a chemically defined methanal solution, the diagnostic certification does not alter its classification under this tariff item, consistent with Chapter 29 Note 1(a) and (d).
Formaldehyde for Plywood Resin Production
>- Technical grade formaldehyde solution optimized for phenol-formaldehyde plywood adhesives. The formulation specifications do not override the chemical definition of methanal, so it remains classified under this tariff item as an acyclic aldehyde without other oxygen functions.
Formaldehyde for Urea Resin Synthesis
>- Pharmaceutical/purity grade formaldehyde specifically for pharmaceutical intermediate synthesis. The intended use does not affect classification under this tariff item, as it is a pure chemically defined compound meeting Chapter 29 Note 1(a).
Formaldehyde Semiconductor Processing Grade
>- Ultra-high purity formaldehyde for photoresist manufacturing in semiconductor production. As a chemically defined methanal compound, it meets the Chapter 29 requirements for electronic chemical intermediates and is classified under this tariff item.
Formaldehyde 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 without other oxygen functions, as per Chapter 29 Note 1(d), and falls under this tariff item.
Formaldehyde with Anticaking Agent
>- Methanal solution with an added anticaking agent for bulk storage stability. The anticaking agent is allowed under Chapter 29 Note 1(f) as a stabilizer necessary for preservation or transport, provided it does not make the product suitable for a specific use rather than general use. It therefore remains classified under this tariff item.
Formalin Tissue Fixative Solution
>- Buffered 10% formalin solution specifically formulated for histological tissue preservation in medical labs. The buffers do not constitute other oxygen functions, so the product remains classified as methanal solution under this tariff item.
High Purity Formaldehyde 99% Distilled
>- Distilled high-purity methanal (99%) for specialty chemical synthesis and electronics. As a separate chemically defined compound meeting strict purity standards, it is classified under this tariff item per Chapter 29 Note 1(a).
Industrial Formaldehyde 50% Solution
>- High-concentration 50% aqueous formaldehyde for urea-formaldehyde resin manufacturing. The concentration does not affect the classification as a methanal solution under Chapter 29 Note 1(d), so it falls under this tariff item.
Methanal (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, classified under this tariff item per Chapter 29 Note 1(d).
Stabilized Formaldehyde for Textile Finishing
>- Formaldehyde solution with a 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 1(f), so it remains classified under this tariff item.
