What is the US duty on copper gluconate from China?
The USITC extract imported on 25 September 2026 does not use the words copper gluconate, cupric gluconate, or copper D-gluconate. This page does not state a rate for those names.
Gluconic acid, HTS 2918.16.10.00, stores 6 percent general and 25 percent other. HTS 2918.16.50, described as Other, stores 3.7 percent and 25 percent. This page does not copy either pair onto copper gluconate. HTS 2918.16.50.90 is described only as Other and stores no rate. HTS 2918.16 stores no rate. The anti-dumping file dated 16 May 2026 stores heading 2918 on citric acid cases, not gluconate. This file does not store a Section 301 percent for a name it does not list. 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.
HTS 2918.16 stores no rate. Gluconic acid stores 6 percent and 25 percent, unit kg, and has no footnote. Its special-rate text is Free (A,AU,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG). That text does not name China and does not include K. This page does not use 6 percent as a copper gluconate rate, and it does not treat that Free text as a China total.
HTS 2918.16.50 is described only as Other. It stores 3.7 percent general and 25 percent other. Its special-rate text is Free (A,AU,BH,CL,CO,D,E,IL,JO,K,KR,MA,OM,P,PA,PE,S,SG). That text includes K and does not name China. There is no footnote. This page does not copy 3.7 percent onto the missing name. Sodium gluconate and calcium gluconate are the named suffixes. Both store no rate. The sodium answer is on US duty on sodium gluconate from China.
HTS 2918.16.50.90 is described only as Other. The unit is kg. The general rate, the special rate, and the other rate are blank. There is no footnote. Additional duties are blank. This page does not call that suffix copper gluconate. A blank is not Free and not zero. Cobalt gluconate is also absent. The answer is on US duty on cobalt gluconate from China. This page does not treat one missing name as the other.
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, not copper gluconate. duty_rate_percent is null on both. The only copper product text in the file is seamless refined copper pipe and tube, A-570-964, heading 7411. That row also stores no cash-deposit percent, and it is not this name. A missing product is not a finding that no order exists. Check ACCESS before you treat the gap as a clearance.
