What US Tariffs Add to a Chinese Single-Use Medical Device Order

A US distributor, private-label owner, or hospital buyer pricing a China-origin circumcision device, NPWT dressing, or injection needle is not looking up "the China medical tariff." The expensive 2026 mistakes are narrower: copying 25% for all of Heading 9018, leaving an IEEPA percentage in a 2025 worksheet, and treating a sample under $800 as duty-free. On 20 February 2026 the Supreme Court held that IEEPA does not authorize the President to impose tariffs. ¹⁴ The $800 administrative exemption is suspended for commercial freight and for mail. ^{6 7}

This brief states the stack that can be checked, and it stops where the instruments stop. The USITC China Tariffs file maps 9018.31.00 and 9018.32.00 to 9903.91.03, and 9018.90.20, 9018.90.30, 9018.90.60, and 9018.90.75 to 9903.88.01. ¹ CBP's filing message puts products of China under 9903.05.31 at 12.5%. ² USTR's September 2024 determination set the syringe and needle increase at 100%, not 50%. ⁴ Nothing in those instruments classifies a VEMERIX stapler, dressing, or needle. The importer's broker does that on the entry.

Which duty layers stack on a China-origin single-use device order in September 2026?

A customs entry for medical devices entering the United States does not pay a single, monolithic duty rate. Instead, the final customs liability is an additive stack of statutory baseline duties, trade remedy actions authorized under separate statutory authorities, and administrative processing fees. For an order arriving from a Chinese production facility on 23 September 2026, the stack is constructed from five distinct components:

• Column 1 General. This is the base rate on the HTS line. The 23 September 2026 lane page for 9018.90.80.00 from China shows 0%. ⁸ Confirm every other line on hts.usitc.gov the day the entry is filed. Do not copy 0% from one statistical line onto the next.
• Original Section 301 lists. Membership is the USITC China Tariffs file. Lines under 9903.88.01, 9903.88.02, or 9903.88.03 are the 25% actions. List 4A is heading 9903.88.15 at 7.5%. A line that is absent does not inherit a neighbor's rate. ¹
• Syringes and needles. The 12 September 2024 determination raised 9018.31.00 and 9018.32.00 to 100% from 27 September 2024, reported under 9903.91.03. Enteral syringes of statistical reporting number 9018.31.0080 were excluded under 9903.91.10 only before 1 January 2026. ⁴
• Forced-labor Section 301 action. For entries on or after 12:01 a.m. eastern time on 24 July 2026, heading 9903.05.31 assesses an additional 12.5% on products of China, except products described in headings 9903.05.85 through 9903.05.92. ² Note 52(a) says that, apart from subdivisions (b) through (k), those goods remain subject to other Chapter 99 additional duties. The 12.5% layer stacks on a 25% or 100% list duty. It does not replace that duty. ³ A broker alert describes the same stack. ¹³ The controlling sentence is note 52(a).
• Merchandise processing fee and harbor maintenance fee. Formal entries pay the merchandise processing fee at 0.3464% of entered value. Through 30 September 2026 the formal limits are a $33.58 minimum and a $651.50 maximum. ¹⁷ From 1 October 2026 the limits are $34.58 and $670.86. ¹⁸ Informal entries use the flat fees in those notices, not the formal percentage. Ocean cargo also pays the harbor maintenance fee at 0.125% under 19 CFR § 24.24.

Two charges that 2025 worksheets still carry are not a 23 September 2026 device entry. Learning Resources, Inc. v. Trump, No. 24-1287, held that IEEPA does not authorize the President to impose tariffs. The orders before the Court were the drug-trafficking and reciprocal tariffs. ¹⁴ A commercial lane changelog records an IEEPA charge coming off on 20 February 2026. ⁸ The holding is the Court's. The broker still confirms that the current HTS no longer carries an IEEPA Chapter 99 line. Separately, the proclamation published as Federal Register document 2026-03824 imposed a 10% temporary surcharge under Section 122 of the Trade Act of 1974 from 12:01 a.m. eastern standard time on 24 February 2026 through 12:01 a.m. eastern daylight time on 24 July 2026. ¹⁵ A parcel-forwarder explainer describes the handoff from that temporary 10% surcharge to the 12.5% tier. ¹⁰ The surcharge ended on the proclamation's own clock. The forced-labor action is a different statute that applies to entries from the same moment. ³ It is not Section 122 under a new name.

Why must you check the 10-digit HTS line instead of a heading-level 25 percent figure?

Heading rates are the recurring quote error. This site's landed-cost guide, from an ex-works quote to a defensible landed cost per unit, says China-origin devices under Subheading 9018.90 carry an additional 25% Section 301 duty. Its worked example then places disposable circumcision devices on 9018.90.60. That statistical line is on the China Tariffs file under 9903.88.01. It is the electro-surgical instruments line. The example is not a ruling that a manual circumcision stapler is electro-surgical. ¹

The rest of that guide — MOQ, size mix, packaging, and the per-unit worksheet — is still the right commercial arithmetic. The tariff sentences are not current. This page does not edit that guide, and it does not replace 9018.90.60 with a binding classification under 9018.90.80.00.

In the China Tariffs extract read for this article, 9018.90.20, 9018.90.30, 9018.90.60, and 9018.90.75 map to 9903.88.01. The file then goes from 9018.90.75 to 9021.50.00. 9018.90.80 is not in that gap, and no 9019 line is either. ¹ The 23 September 2026 lane page for 9018.90.80.00 from China shows 0% Column 1, no original-list duty, and 12.5% under 9903.05.31. ⁸ If the broker's line is 9018.90.80 and the file still omits it, the original-list rate is zero and the forced-labor layer is the remaining Section 301 duty, unless note 52 exempts the line. A blanket 25% figure overstates that result by 12.5 percentage points. Adding 25% on top of the 12.5% layer overstates it by 25 percentage points.

The reverse error is filing an electro-surgical article on 9018.90.60 as if it were the unlisted residual line. Note 52(a) stacks 12.5% on the 25% list duty, which is 37.5% of Section 301 duty before fees. ³ An aggregator that prints 25% for all of Heading 9019 makes the same heading-level mistake. ⁹ The missing 9019 row in this extract is a reason to search the file. It is not a classification of an NPWT pump, and the extract did not cover Heading 3005.

• 9018.90.20, 9018.90.30, 9018.90.60, and 9018.90.75 — present in the extract, each mapped to 9903.88.01. 9018.90.60 is the electro-surgical line the August 2026 worked example used.
• 9018.90.80 — not in the gap after 9018.90.75. The lane page shows no original-list duty. That is a fact about the line, not a decision that a circumcision stapler, ring, or anastomat kit belongs on it.

Why can one line pay 12.5 percent and another pay 112.5 percent?

The same Chinese factory can ship SKUs whose Section 301 stacks are far apart. Each row answers what the named HTS line pays if the broker uses that line. None of them assigns a VEMERIX catalog number to a line.

• 9018.90.80.00, if it remains off the file: no original-list duty, plus 12.5% under 9903.05.31 unless note 52 exempts it. The lane page matches that reading. ^{8 2} A manual circumcision stapler may or may not be this line. The August 2026 example used 9018.90.60.
• 9018.90.60: 25% under 9903.88.01 plus 12.5% under 9903.05.31, or 37.5% before fees. ^{1 3}
• 9018.32.00 and 9018.31.00: 100% under 9903.91.03 since 27 September 2024, plus 12.5% under 9903.05.31, or 112.5 percentage points before fees, unless note 52 or a live exclusion removes a layer. ^{4 2} Tables that still print 50% for syringes and needles contradict 89 FR 76581. Enteral syringes in 9018.31.0080 were excluded only before 1 January 2026.
• NPWT dressings and pumps are not given a line here. One aggregator prints 25% for Heading 9019. ⁹ No 9019 line appeared between 9018.90.75 and 9021.50.00. That says nothing about Heading 3005. Put a percentage into the NPWT pump total-cost model only after the broker searches the current file for the actual 10-digit line.

The commercial consequence follows the line. A 12.5% layer on an unlisted surgical instrument is one input next to the public price benchmarks for single-use consumables. A 112.5-point Section 301 stack on 9018.31 or 9018.32 more than doubles dutiable value before freight, fees, and margin, unless an exemption or exclusion covers that entry. Treat a China-origin needle quote for the United States as not comparable until the broker produces that text.

What happened to duty-free sample shipments under 800 dollars?

Evaluation samples — rings, a stapler, a dressing kit — used to move under 19 U.S.C. § 1321(a)(2)(C) when the fair retail value imported by one person on one day did not exceed $800. That exemption is suspended.

• Modes other than international mail. Federal Register document 2026-12670, effective 24 June 2026, suspends the exemption indefinitely. A commercial shipment at or under $800 uses formal or informal entry. ⁶
• International mail. Federal Register document 2026-12669, published the same day, suspends the postal exemption effective 24 July 2026, except the amendment to 19 CFR 145.31, which is effective 24 June 2026. ⁷ The 22 October 2026 date is the compliance date for the advance-data elements in 19 CFR 145.12(a)(2)(v) and (vi). It is not the day the duty exemption ends. From that compliance date, merchandise subject to a partner-government-agency requirement is outside the new mail informal-entry process. FDA-regulated devices are in that group.

A low-value sample still needs a 10-digit line, a supportable value, and the duty stack for that line. Courier disbursement charges are the carrier's fees, not a CBP schedule, and this page does not quote a range for them. Marking an invoice "samples of no commercial value" does not restore Section 321 treatment. The importer of record still owes reasonable care under 19 U.S.C. § 1484. Undervaluation can produce a CBP inquiry and, where negligence or fraud is found, penalties under 19 U.S.C. § 1592. The marking is not itself a seizure.

What should the RFQ and tender file now say about tariffs and origin?

To prevent catastrophic landed-cost overruns and regulatory non-compliance, hospital procurement committees and distributor sourcing directors must eliminate colloquial or ambiguous trade terms from their RFQs. A supplier answer of "customs duty is around 25%" or "medical consumables are tariff-exempt under WTO rules" is not a line. Send it back. The quote file needs these five fields:

When drafting international distribution agreements, pricing clauses must explicitly articulate tariff allocation. Terms quoted as DDP (Delivered Duty Paid, Incoterms 2020) transfer border duty risk to the supplier, but foreign manufacturers rarely possess a US business entity, continuous customs bond, or licensed broker network capable of acting as the importer of record. In contrast, under FOB (Free on Board) or CIF (Cost, Insurance & Freight) terms, the US distributor acts as the importer of record, bearing complete statutory liability under 19 U.S.C. § 1484 for proper tariff classification, valuation, and duty remittance.

Which four clocks could move these numbers before the order clears?

An order placed in late September 2026 can arrive in November 2026 or January 2027. That transit does not create four equal risks. Two dates are printed in the Federal Register. One investigation is open and has no outcome on this page. The same 10 November date is also repeated as the end of a 2025 US-China tariff arrangement. The exclusion extension is the part of that date in the Federal Register. The reciprocal and fentanyl pieces were IEEPA tariffs, and they do not come back as a duty after 20 February 2026.

Commerce initiated the Section 232 investigation of PPE, medical consumables, and medical equipment, including devices, on 2 September 2025. Comments were due 17 October 2025. ¹² Pharmaceuticals are outside that docket because the notice put them in a separate investigation. A search for this article did not locate a proclamation or an HTS annex imposing Section 232 duties on medical consumables. The June 2026 proposal had spoken generally of articles subject to Section 232 tariffs. The final note is a list. Heading 9903.05.90, as printed in 91 FR 47318, exempts enumerated steel, aluminum, copper, vehicle, wood, and semiconductor provisions, and the notice adds patented pharmaceutical articles to that description. ³ A later medical-device proclamation removes the 12.5% layer only if it, or a later USTR notice, changes 9903.05.31 or note 52. Until that text exists, leave 12.5% in the model.

How do you verify the stack on entry day without paying for a wrong line?

A rate copied in September can be the wrong rate in November. On entry day the broker, not the invoice footer, runs this check.

1. Read the 10-digit line on the current HTS. Confirm on hts.usitc.gov that the statistical suffix still exists and what Column 1 General says that day.
2. Search the current USITC China Tariffs file for that exact line. Use the Chapter 99 heading printed beside it. Headings 9903.88.01, 9903.88.02, and 9903.88.03 are the 25% lists. Heading 9903.88.15 is List 4A at 7.5%. Heading 9903.91.03 is the 100% syringe and needle increase. Other 9903.88 and 9903.91 headings have their own rates. ¹ Absence from the file supports a zero original-list duty. Absence from only three headings does not.
3. Apply 9903.05.31 only after the note 52 check. Products of China pay 12.5% except goods described in headings 9903.05.85 through 9903.05.92, and except the note 52(a) baggage and Chapter 98 rules. ^{2 3} Do not switch the duty off because a Section 232 investigation is open. Switch it off only when the current exemption text names the line.
4. Read that day's CBP CSMS messages on the CBP bulletin page for a heading change or an exclusion filing code. CSMS #69326983 is the July instruction. ² It is not the last instruction that will matter. List and exclusion notices are collected on the USTR tariff-actions page. ⁵
5. Ask CBP when the line is actually in doubt. A kit that could be an instrument under Heading 9018 or a dressing under Heading 3005 is that question. Binding rulings go through eRulings. A supplier's recommended export code is not a ruling. Material false-statement exposure under 19 U.S.C. § 1592 sits with the importer.

Where VEMERIX fits — and where due diligence still begins

VEMERIX is the international brand of Weihai Medison Medical Equipment Co., Ltd., positioned as a Minimally Invasive Surgery Total Solution Platform serving urology, vascular surgery and perioperative care. The supplier can hand over the product record. It cannot file the US entry.

• Circumcision ring. NMPA Class II, registration Lu Mech Reg. 20172020238, ethylene-oxide sterilized, 14 size codes, and a CE mark recorded for this ring. The anastomat kit and the circumcision stapler are separate Class II registrations. The 14-size range and the CE mark do not automatically transfer to them.
• NPWT dressing kit. A Class II side-suction dressing kit. This page does not assign it Heading 3005 or any 10-digit line. The duty cell in a total-cost model stays blank until the broker's line is known.
• Injection needle. An NMPA Class III sterile single-use needle. If the US line is 9018.31.00 or 9018.32.00, budget the 112.5-point Section 301 stack unless an exemption or exclusion covers that entry. Do not treat the category as open without that text.
• Registration files for the circumcision range are in the registration evidence pack by target market. Tender specification questions are in the public tender specification evidence for single-use devices. Neither file is a customs classification.

VEMERIX does not act as the US importer of record, does not hold a US trade-remedy exclusion, and does not provide brokerage or classification advice. A recommended export code, including any code in the 9018.90 family, is a description for the broker to test. Confirm the 10-digit line, note 52, and the fee year — FY2026 formal limits through 30 September 2026, FY2027 limits from 1 October 2026 — before a purchase order treats the duty as known. Specification requests go through downloads, quality, and contact.

Frequently asked questions

Does the 12.5 percent forced-labor tariff apply to every Chinese medical device?
No. CSMS #69326983 assesses 12.5% under 9903.05.31 on products of China except products described in headings 9903.05.85 through 9903.05.92. ² Note 52(a) also excepts personal goods in accompanied baggage and Chapter 98 claims other than the stated 9802 repair, alteration, and assembly cases, and it keeps other Chapter 99 additional duties in the stack apart from subdivisions (b) through (k). ³ Heading 9903.05.90 currently names steel, aluminum, copper, vehicles, wood, semiconductors, and patented pharmaceutical articles as added in the notice. Assume the 12.5% layer applies until the broker finds the line in that text.

The IEEPA tariffs were struck down. Why does the order still pay duty?
Learning Resources, Inc. v. Trump held on 20 February 2026 that IEEPA does not authorize the President to impose tariffs. ¹⁴ That holding covers the challenged drug-trafficking and reciprocal orders. Section 301 of the Trade Act of 1974 is a different statute, and both the line-level China lists and the 12.5% forced-labor action sit there. Drop an IEEPA percentage from a 2025 worksheet only after the broker confirms the current HTS no longer carries it. ⁸

Is 25 percent still the Section 301 rate for HTS 9018.90?
Only on the statistical lines that are actually listed. The extract maps 9018.90.20, 9018.90.30, 9018.90.60, and 9018.90.75 to 9903.88.01. ¹ 9018.90.80 does not appear between 9018.90.75 and 9021.50.00. The older landed-cost guide's blanket Subheading 9018.90 sentence, and its use of 9018.90.60 in a circumcision-device example, are not a current line-level answer. This page does not establish a manual stapler as either code.

Do tariff changes require a new 510(k) or FDA establishment registration?
No. Title 19 classification and Title 21 device authorization are different regimes. A new Chapter 99 heading does not create, amend, or cancel a 510(k), a device listing, or a foreign establishment registration. An FDA-regulated import can still need the agency's product code and listing data on the entry. This page does not claim a US authorization for a VEMERIX device.

Can an exclusion cut the rate?
Only when the product fits the text of a live exclusion. USTR collects those notices on its tariff-actions page. ⁵ The 1 December 2025 notice extends 178 exclusions through 11:59 p.m. eastern daylight time on 9 November 2026. ¹⁶ The solar-manufacturing exclusion under U.S. note 20(www), heading 9903.88.70, applied before 1 June 2025. It is not an open path for a disposable device. Enteral syringes in 9018.31.0080 were excluded under 9903.91.10 only before 1 January 2026. ⁴ The entry has to cite the exclusion heading. Someone else's exclusion does not transfer.

If a Section 232 medical-device tariff is imposed, does the 12.5 percent layer disappear?
Not on the current text. Heading 9903.05.90 exempts the enumerated categories above, including patented pharmaceutical articles as added in 91 FR 47318. ³ It does not say that a future medical-consumable proclamation turns 9903.05.31 off. Remove the 12.5% layer only when a proclamation or a later USTR notice amends that heading or note 52. Until then the investigation is a monitoring item, not a credit against the quote. ¹²

If the HTS line is wrong, is the Chinese supplier or the US importer responsible?
The importer of record, under 19 U.S.C. § 1484. The supplier can provide an invoice and a recommended export code. The party that files the entry summary is the party that owes reasonable care. A wrong line can produce a request for information, a rate advance, and, where negligence or fraud is found, penalties under 19 U.S.C. § 1592 against that importer.
