3914.00.60

Analysis

HTS 3914.00.60 covers ion-exchangers based on polymers of headings 3901 to 3913, in primary forms: other under heading 3914 (ion-exchangers based on polymers of headings 3901 to 3913, in primary forms).

Neighbouring lines carry rates from duty-free to duty-free, so the exact line matters. The widest gap is with 3914.00.20 (cross-linked polyvinylbenzyltrimethylammonium chloride…), at duty-free: a product that belongs there but is entered here, or the reverse, changes the duty by 3.9 percentage points.

The general duty rate is 3.9% of the customs value, which is at the low end of the rates in chapter 39 (29th percentile of 236 lines with an ad valorem rate). On a shipment valued at $10,000 that is $390 in duty before any Chapter 99 additions or preference claims.

Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 13 others can enter duty-free instead of paying 3.9%. It is also eligible under GSP, the developing-country programme, which Congress has to renew; check whether GSP is in force on the entry date.

The column 2 rate, for countries without normal trade relations, is 35%, 9.0 times the general rate.
