The purpose of this report is to collect economic information regarding the production and sales of candles and incense in the US, including information about imports. A second objective is to review the scientific literature regarding emission rates and potential human health effects associated with burning candles and incense. The following is a brief overview of the findings.
Many manufacturers are very small.
The top five countries that export candles to the US are China, Taiwan, England, Hong Kong, and Mexico. Limited discussions with some industry representatives indicate that there are probably many more very small manufacturers. The top five countries that export incense to the US are India, China, Thailand, Japan, and Hong Kong. In the scientific literature we reviewed, zinc and tin were found not to be emitted at concentrations that would raise concerns when burned indoors. Sooting can occur when combustion conditions are impaired when burning candles.
