Bear Mr. Greeley:
This is in response to your August 29, 2000 letter, in which you ask if our February 14, 1997, letter regarding an exception for shipments of water samples is still valid and if any quantity limitations exist.
This exception from the Hazardous Materials Regulations (HMR; 49 CF,,R Parts 171-180) concerns the shipment of water samples containing limited quantities of various Class 8, corrosive materials. The materials noted in the exception are as follows:
Hydrochloric acid (HC1), in water solutions at concentrations of 0.04% by weight or less;
Mercury chloride (HgCl2), in water solutions at concentrations of 0.004% by weight or less;
Nitric acid (HNO3), in water solutions at concentrations of 0.15% by weight or less;
Sulfuric acid (H2SO4)1 in water solutions at concentrations of 0.35% by weight or less;
Sodium hydroxide (NaOH), in water solutions at concentrations of 0.080% by weight or less; and
Phosphoric acid (H3PO4) in water solutions at concentrations yielding a pH range between 4 and 2.
This exception is still valid. The above listed materials in water solutions in the concentrations identified are not subject to the HMR and therefore there is no quantity limitation.
I hope this satisfies your request.
Sincerely,
John A. Gale
