Tetrabromocyclooctane (TBCO)

Tetrabromocyclooctane is a brominated cyclic alkane used primarily as a flame retardant additive in plastics and polymers. It falls under HTS 2903.89.60.00 as a halogenated derivative of cyclanic hydrocarbons, specifically named in the tariff schedule. This white crystalline powder provides high bromine content for effective fire suppression in materials.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3824.99Lower: 17.5% vs 37.5%

If blended with plasticizers or supplied as flame retardant mixture

Mixtures of chemicals not chemically defined fall under Chapter 38 prepared binders, rather than pure organic compounds of Chapter 29.

2903Same rate: 37.5%

If imported as technical grade with significant impurities

Less pure halogenated cyclanic hydrocarbons may classify under 'other' subheadings if not meeting specific compound criteria.

2909.49Lower: 18% vs 37.5%

If for industrial use in polymer additives sold in bulk formulations

Certain brominated compounds used as additives may shift to oxygen-function derivatives if containing ether linkages, though rare for TBCO.

Import Tips & Compliance

• Provide Safety Data Sheets (SDS) and confirm REACH compliance for EU markets or TSCA registration for US

• Verify purity levels (>98%) as impurities may affect classification; include certificate of analysis

• Check for flame retardant restrictions under Stockholm Convention; avoid common pitfalls like mislabeling as general brominated hydrocarbon
