Dust explosions and the chemicals behind cellulose ethers
What this tab covers How it is regulated and what could disrupt supply: hazard classification, rules in the EU, US and India, anti-dumping duties and other trade measures, and supply-risk notes.
Hazards
Classification
UN number
Key risks
not classified; combustible dust
none
Dust explosions in milling and drying; cellulose ether plants handle methyl chloride and propylene oxide.
Main rules
Where
Rule
Effect
EU
Modified starches are food additives E1404-E1452 under Regulation 1333/2008; CMC is E466, HPMC E464
Approval and labelling as E-numbers; native starch is a food ingredient.
US
21 CFR 172.892 (food starch-modified); GRAS for native starch
Permitted treatments and limits.
Codex
INS numbers 1400-1452 for modified starches
International acceptance.
India
Rule
Effect
FSSAI Food Additives Regulations (modified starches INS 1400 series)
Permitted uses and limits
Ethanol interest subvention and maize procurement for E20
Raises maize demand and starch costs (Mordor via GII)
Trade measures
No anti-dumping duty on starch found in sources reached
Supply risk
Low concentration and many producing countries; risk is maize price shocks from weather and biofuel policy. Not on critical lists.
