What is the US duty on sodium gluconate from China?
The USITC extract imported on 25 September 2026 names sodium gluconate on HTS 2918.16.50.10. That line stores no rate. The general rate, the special rate, and the other rate are blank.
The parent line, HTS 2918.16.50, stores 3.7 percent general and 25 percent other. This page does not copy those rates onto the sodium gluconate suffix, and it does not read a blank as Free or as zero. Additional duties are blank, so this file does not store a Section 301 percent. These figures are not a China total. This page is the United States file only. It does not state an Australian duty or a ChAFTA percent.

The other column is not shown. It does not apply to goods of China.
Gluconic acid stores 6 percent, not 3.7 percent. Its special-rate text does not name China and does not include K. The parent Other line stores 3.7 percent, and its special-rate text includes K. The sodium gluconate suffix does not store either rate, and its special rate is blank. This page does not treat 6 percent or 3.7 percent as a China total, and it does not copy either figure onto sodium gluconate or onto calcium gluconate. HTS 2918.16.50.90, described only as Other, also stores no rate.
The anti-dumping file, updated_at 2026-05-16T23:32:23.566Z, stores heading 2918 on A-570-937 and C-570-938. The product text on both rows is Citric acid and certain citrate salts. Exporting country is China. duty_rate_percent is null on both. The product text does not name sodium gluconate or gluconic acid. A heading tag is not this product. That gap is not a finding that no order exists. Check ACCESS before you treat it as a clearance. The citric acid answer is on US duty on citric acid from China.
