Last updated: July 2026 data

Polybutadiene rubber (BR) is a high-cis synthetic elastomer prized for its exceptional abrasion resistance and low-temperature flexibility, making it a critical blending component in truck and passenger-tire sidewalls and golf-ball cores. Its production is highly concentrated among a small number of petrochemical complexes, so supply disruptions in butadiene feedstock markets can create rapid price volatility for downstream compounders. BR is traded in primary forms — bales, crumbs, and pellets — and the specific microstructure (high-cis vs. low-cis) is a key specification that buyers should confirm with suppliers before import.

Frequently Asked Questions

Does the cis-content grade of butadiene rubber affect its HTS or SITC classification?

No — high-cis and low-cis polybutadiene both classify under the same heading. However, cis-content is a critical commercial specification that should be documented in the purchase contract and certificate of analysis, as it directly affects end-use suitability and can influence customs valuation if unit prices differ significantly between grades.

What physical forms of BR are typically imported, and does form affect classification?

BR is commonly imported as bales, crumbs, or pellets. All of these qualify as 'primary forms' under SITC 23212, so the physical presentation does not change the classification. Importers should confirm that the product has not been further processed into sheets or strips of a defined thickness, which could shift the classification.
