RE: INITIATION OF ANTIDUMPING DUTY INVESTIGATION OF SODIUM
AND POTASSIUM PHOSPHATE SALTS FROM CHINA (A-570-962)


THERE ARE NO RESTRICTIONS ON THE RELEASE OF THIS INFORMATION.

1. ON OCTOBER 21, 2009, COMMERCE WILL PUBLISH IN THE FEDERAL
REGISTER ITS INITIATION OF CERTAIN SODIUM AND POTASSIUM
PHOSPHATE SALTS FROM THE PEOPLES REPUBLIC OF CHINA.

2. THE PHOSPHATE SALTS COVERED BY THIS INVESTIGATION INCLUDE
SODIUM TRIPOLYPHOSPHATE (STPP), WHETHER ANHYDROUS OR IN
SOLUTION, ANHYDROUS MONOPOTASSIUM PHOSPHATE (MKP), ANHYDROUS
DIPOTASSIUM PHOSPHATE (DKP) AND TETRAPOTASSIUM PYROPHOSPHATE
(TKPP), WHETHER ANHYDROUS OR IN SOLUTION (COLLECTIVELY
PHOSPHATE SALTS).

STPP, ALSO KNOWN AS SODIUM TRIPHOSPHATE, TRIPOLY OR
PENTASODIUM TRIPOSPHATE, IS A SODIUM POLYPHOSPHATE WITH THE
FORMULA NA5O10P3. THE AMERICAN CHEMICAL SOCIETY, CHEMICAL
ABSTRACT SERVICE (CAS) REGISTRY NUMBER FOR STPP IS 7758-29-4.
STPP IS TYPICALLY 25% PHOSPHORUS, 31% SODIUM AND AND 57%
DIPHOSPHORUS PENTOXIDE (P2O5). STPP IS CLASSIFIED UNDER
HEADING 2835.31.0000, HTSUS.

TKPP, ALSO KNOWN AS NORMAL POTASSIUM PYROPHOSPHATE,
DIPHOSPHORIC ACID OR TETRAPOTASSIUM SALT, IS A POTASSIUM SALT
WITH THE FORMULA K4P2O7. THE CAS REGISTRY NUMBER FOR TKPP IS
7320-34-5. TKPP IS TYPICALLY 18.7% PHOSPHORUS AND 47.3%
POTASSIUM. IT IS GENERALLY GREATER THAN OR EQUAL TO 43.0%
P2O5 CONTENT. TKPP IS CLASSIFIED UNDER HEADING 2835.39.1000,
HTSUS.


MKP, ALSO KNOWN AS POTASSIUM DIHYDROGEN PHOSPHATE, KDP, OR
MONOBASIC POTASSIUM PHOSPHATE, IS A POTASSIUM SALT WITH THE
FORMULA KH2PO4. THE CAS REGISTRY NUMBER FOR MKP IS 7778-77-0.
MKP IS TYPICALLY 22.7% PHOSPHORUS, 28.7% POTASSIUM AND 52%
P2O5. MKP IS CLASSIFIED UNDER HEADING 2835.24.0000, HTSUS.

DKP, ALSO KNOWN AS DIPOTASSIUM SALT, DIPOTASSIUM HYDROGEN
ORTHOPHOSPHATE OR POTASSIUM PHOSPHATE, DIBASIC, HAS A
CHEMICAL FORMULA OF K2HPO4. THE CAS REGISTRY NUMBER FOR DKP
IS 7758-11-4. DKP IS TYPICALLY 17.8% PHOSPHORUS, 44.8%
POTASSIUM AND 40% P2O5 CONTENT. DKP IS CLASSIFIED UNDER
HEADING 2835.24.0000, HTSUS.

THE PRODUCTS COVERED BY THIS INVESTIGATION INCLUDE THE
FOREGOING PHOSPHATE SALTS IN ALL GRADES, WHETHER FOOD GRADE
OR TECHNICAL GRADE. THE PRODUCT COVERED BY THIS INVESTIGATION
INCLUDES ANHYDROUS MKP AND DKP WITHOUT REGARD TO THE PHYSICAL
FORM, WHETHER CRUSHED, GRANULE, POWDER OR FINES. ALSO
COVERED ARE ALL FORMS OF STPP AND TKPP, WHETHER CRUSHED,
GRANULE, POWDER, FINES OR SOLUTION.

FOR PURPOSES OF THE INVESTIGATION, THE NARRATIVE DESCRIPTION
IS DISPOSITIVE, NOT THE TARIFF HEADING, AMERICAN CHEMICAL
SOCIETY, CAS REGISTRY NUMBER OR CAS NAME, OR THE SPECIFIC
PERCENTAGE CHEMICAL COMPOSITION IDENTIFIED ABOVE.

3. FOR FURTHER REPORTING PURPOSES THIS CASE HAS BEEN ASSIGNED
INVESTIGATION NUMBER A-570-962.

4. IF THERE ARE ANY QUESTIONS REGARDING THIS MATTER BY CBP
OFFICERS, THE IMPORTING PUBLIC OR INTERESTED PARTIES, PLEASE
