Get a regular tariff wrong and your quote’s margin takes the hit. Step on AD/CVD without noticing and the entire shipment — duties plus penalties — can erase a year. The two live in different weight classes, yet Taiwanese exporters routinely file both under the same “tariffs” drawer: plenty of people check duty rates before shipping; far fewer check the AD/CVD order list.

What AD/CVD is: a second regime stacked on the tariff
AD (antidumping duties) target imports sold below normal value; CVD (countervailing duties) target subsidized imports. The Commerce Department investigates and determines; CBP collects. Three properties matter:
- They stack: AD/CVD adds on top of the schedule rate and other surcharges — it does not replace them
- They are country-and-product specific: every order defines a product scope and covered countries
- The rates can be enormous: large enough to rewrite a cost structure outright — and they vary by order and by producer, so check the currently effective version before shipping instead of quoting numbers from old articles
Taiwan is not a bystander
“AD/CVD is a China problem” is a dangerous misreading. Taiwan has its own record of orders and investigations:
- Steel: Taiwanese corrosion-resistant steel products have carried steep US antidumping rates, and other steel categories have cycled in and out of proceedings — anything in the steel chain gets the list checked, every time
- Chemicals: Taiwanese chemical products likewise have investigation history
- Extended vigilance: solar, fasteners, pipe fittings — categories the US files against frequently; Taiwan being off a list today does not keep a new petition from naming it tomorrow
One-sentence principle: these categories have precedent, but orders and rates move constantly — only the list as of your shipping date counts. Note also that measures can reach backward: goods released during an investigation can owe duties retroactively at the final determination, so “already cleared” does not mean “safely landed” — price the tail risk into the quote.
The pre-shipment check sequence
- First, classify correctly: AD/CVD scopes are defined by tariff codes plus product descriptions — a wrong HTSUS classification makes you check the wrong list, which is why we call classification the foundation
- Second, check the official order lists: CBP and Commerce publications, current version, product against origin — not blog posts, not last year’s slide deck
- Third, when in doubt, request a Scope Ruling: where a product’s coverage under an order is genuinely uncertain, ask Commerce for a formal scope determination instead of betting on one port’s interpretation
The shortcut never to take: third-country routing
Routing AD/CVD-covered goods through a third country for a new identity is EAPA’s textbook target: back duties, penalties, full-chain scrutiny, and escalation in serious cases. The logic mirrors Section 301 transshipment exactly — origin follows substantial transformation, not the routing — and a Taiwanese factory that launders origin for others pledges its own export credibility as collateral.
Where SKYCARGO fits
SKYCARGO INC folds the AD/CVD list into every pre-shipment duty run: tariff code, product description and origin checked against current orders, with any exposure flagged before you quote — not after the goods reach port. Where a Scope Ruling or legal read on coverage is needed, we say so plainly and point you to compliance counsel; our role is logistics and documentation support (the Importer of Record is normally you, as a non-resident importer, with entries filed through our partner licensed customs broker), and we do not gamble compliance on your behalf. We act as Importer of Record for a client’s goods in one situation only: when we are your selling agent in the US — under a long-term agency agreement, actually finding buyers and taking orders for you in the US, paid a commission on sales, with warehousing, delivery and customer service continuing after import, and, for food, running the FSVP ourselves. We take these cases only when all of those conditions are met. We do not act as a nominal consignee, collect and forward payments only, or sign a power of attorney only. Run your items past us before shipping. (Personal parcels: Shiptw.)
AD/CVD scope, coverage and rates follow current Commerce and CBP publications. Reference only; consult compliance counsel for specific cases.
