US United States only. Duty and rules for goods made in China and entered into the US. Importing somewhere else? Duty by country

Quartz countertops from China into the US: 62.5% duty, 434‑459% with AD/CVD. 62.5% in quota or 87.5% over it, plus A-570-084 / C-570-085 at 371.47% for an exporter without its own rate.

Ask for NSF 51 if the tops go into a food-service kitchen. Ask for an XRD silica result on each color if a California shop will cut them.

Certificates to check

Add it up and a slab from a Chinese exporter without its own rate pays 433.97% of its entered value in duty. That prices Chinese quartz out of most US jobs. This page shows the math, what sits outside the orders (Chinese granite pays 41.2%), which countries skip the safeguard, and how to check NSF and silica claims yourself.

What the duty does to one entry

A $10,000 lot of slabs from China (entered value, not a container price), ocean freight. The first two columns are for an exporter without its own AD/CVD rate, the third for the exporter with the lowest rate in the order. Granite runs alongside because it is what buyers switch to. Change the value to match your quote.

What each column assumes
  • Chinese quartz, in quota: The rate if your entry is presented while the quarter still has quota left.
  • Chinese quartz, over quota: The rate once the quarterly quota has filled. You cannot fix which one you get when you sign the PO.
  • Lowest company rate, in quota: The exporter with the lowest combined deposit in the order, and only on its own invoices. It still pays several times the slab value in duty.
  • Chinese granite: Quarried stone: outside the quartz orders and outside the safeguard. A Federal Register full-text search of ITA and USITC notices for "granite" on 2026-10-18 found no AD/CVD order on Chinese granite.

The AD/CVD rows are cash deposits. Every exporter with its own rate is in the table under "When AD/CVD reaches the order". Freight, brokerage and inland costs are in the full calculator.

When AD/CVD reaches the order

The orders and the safeguard follow what the slab is made of and where it was pressed, not what the invoice calls it. The order page has the full scope text; these are the calls buyers get wrong.

  • A-570-084 / C-570-085 Quartz surface products In force since 2019-07-11. When in scope: AD 326.15% + CVD 45.32% for an exporter without its own rate. Checked
  • Slabs, countertops, vanity tops, backsplashes and tiles where silica outweighs every other single material, bound with resin A-570-084 In scope +371.47% Any size, thickness or finish, cut to size or not. Pigment or cement in the mix does not take it out. Scope, 84 FR 33053 Appendix I
  • Chinese slab cut, polished or edged in Malaysia, Vietnam or any other third country A-570-084 In scope +371.47% Finishing abroad does not change origin. Malaysian exporters that could not prove a non-Chinese slab were held to the China-wide rate. Scope ruling, 87 FR 64009
  • Quartz tops shipped on a cabinet or vanity A-570-084 In scope +371.47% Only the quartz is covered, by the orders and by the safeguard. A wooden cabinet goes through its own orders and the Section 232 wood tariff. Scope, 84 FR 33053 Appendix I
  • Granite, marble, quartzite and soapstone A-570-084 Out Quarried stone is excluded from the orders and from the safeguard. Scope, 84 FR 33053 Appendix I
  • Porcelain and sintered stone slabs A-570-084 Out No resin binder, so not quartz surface product. Thin porcelain slabs can still be ceramic tile for a separate China order; see the alternatives table below. Scope, 84 FR 33053 Appendix I
  • Crushed glass surfaces A-570-084 Depends Out of AD/CVD only if glass is the largest ingredient, pieces are visible across the face, some exceed 1 cm, and no piece sits more than 3 inches from the next. The safeguard note has no matching exclusion. Scope, 84 FR 33053 Appendix I
  • Quartz tiles entered under a 6810.19 tile line A-570-084 Unconfirmed AD/CVD follows the product, so the orders still reach them. The safeguard names only its own HTS lines, so whether it reaches tiles classified elsewhere is unconfirmed. Get a ruling before you price it either way.

Who pays what under A-570-084 / C-570-085

A deposit, not the final bill
The cash deposit is an estimate paid at entry. Final duty is set when the entry liquidates and can come out higher or lower; the difference is billed or refunded with interest. 19 U.S.C. 1677g (interest on deposits)
Who owes it
The US importer of record. A DDP quote from a Chinese seller removes that exposure only if the seller is the importer of record on the entry. If your company files as importer, the deposit and any later bill are yours. 19 CFR 141.1 (importer liability)
Entries still open
AD entries from July 2026 and CVD entries from January 2026 fall in periods nobody can request a review of until the July 2027 anniversary window. Until that window closes without a request, treat the deposit on those entries as provisional. Opportunity to request review, July anniversaries, 91 FR 39979
Latest review period
No review was requested for the AD period July 2025 to June 2026 or the 2025 CVD year: Commerce's initiation notice for July-anniversary orders (91 FR 56836, 2026-09-04) does not list A-570-084 or C-570-085. Entries from that period are assessed at the cash deposit rate paid at entry (19 CFR 351.212(c)), and the deposits above stay in force. Initiation of AD/CVD administrative reviews, July anniversaries, 91 FR 56836
What the reviews changed
No review has changed any rate in the table since 2019; one review moved two listed separate-rate exporters to the China-wide rate (86 FR 43520). Rescinding the 2024-25 AD review (91 FR 27261) means no new rate was calculated: the only exporter that asked for the review, Karinastone (Malaysia) Sdn Bhd, had no suspended entries in the period, so cash deposit rates do not change and entries from July 2024 to June 2025 are assessed at the cash deposit rate paid at entry. AD review final 2018-2020, 86 FR 43520
Why other sites show other numbers
Pages that quote 265.81% to 336.69% are quoting the dumping margins from the investigation, not deposits. The AD cash deposit is the dumping margin minus an offset for the export subsidies Commerce found in the CVD case, so the AD and CVD deposits do not count the same subsidy twice (84 FR 33053). That is why each AD deposit is lower than its margin. 84 FR 33053
Exporters outside China
An exporter outside China that has no rate of its own pays the AD rate of the Chinese company that supplied it; if that Chinese supplier has no separate rate, the China-wide rate of 326.15% applies (86 FR 43520; 89 FR 92622).

No longer separate-rate: Deyuan Panmin International Limited (Reviewed for 2018-2020 without a separate-rate application or certification; treated as part of the China-wide entity at 326.15% (86 FR 43520).); Xiamen Deyuan Panmin Trading Co., Ltd. (Reviewed for 2018-2020 without a separate-rate application or certification; treated as part of the China-wide entity at 326.15% (86 FR 43520).)

A company rate attaches to the exporter-producer combination named in the notice, and only when that exporter is on your commercial invoice. Any other combination pays the shaded row. Every row checked .

How the Section 201 quota works

The safeguard is a tariff-rate quota, not a flat rate. These are the rules that decide which rate lands on your entry.

  • Two rates 25% while the quarter has quota left, 50% after it fills. Both step down once a year until the safeguard ends; the next step is on 2027-08-15. HTSUS chapter 99, U.S. note 41(e)
  • Quota size 13,006,426 m² in the first year, released in four equal quarters. Unused quota rolls into the next quarter but not into the next year. CBP Quota Bulletin 26-601
  • Who gets the low rate First come, first served across every country that is not exempt, by the time CBP has a clean entry summary, payment and arrival on file. A Chinese slab competes for the same quota as an Indian, Turkish or Vietnamese one. CBP Quota Bulletin 26-601
  • Unit Square meters. Ask the factory for slab count and area per container, because your broker files the quota in m². CBP Quota Bulletin 26-601
  • Stacking The safeguard is charged on top of the base rate, both Section 301 tariffs and AD/CVD. Nothing on a Chinese slab is waived because the safeguard applies. HTSUS chapter 99, U.S. note 41(b)
  • How full the quota is We do not state the fill; it moves with every entry. CBP normally posts a Quota Status Report on the first business day of each week. Find quartz surface products (quota ID 99034530QTZ01 in CBP's bulletin) and compare the quantity entered so far with the quarterly limit. Once the line shows a fill date, entries presented after it pay the over-quota rate until the next quarter opens. CBP Commodity Status Reports (weekly Quota Status Report)

If not Chinese quartz, what then

What the usual substitutes and other origins face. Rates are printed only where our data has them.

  • Granite from China HTS 6802.93.00 pays 41.2%: 3.7% base rate; 25% Section 301 under 9903.88.03 (83 FR 47974); 12.5% 2026 forced-labor Section 301 under 9903.05.31 (91 FR 47318). A Federal Register full-text search of ITA and USITC notices for "granite" on 2026-10-18 found no AD/CVD order on Chinese granite, and quarried stone is outside the safeguard. Federal Register search: granite
  • Porcelain or sintered slabs from China Not quartz, so no quartz orders and no safeguard. But porcelain slabs thinner than 3.2 cm count as ceramic tile for the China ceramic tile orders, whose cash deposits we have not confirmed. Get a scope ruling or a broker opinion before you quote thin porcelain. Ceramic tile orders continued, 91 FR 10065
  • Quartz from India or Türkiye Both have their own quartz AD/CVD orders, continued in January 2026, and neither is on the safeguard exempt list. No China Section 301 applies. Check the exporter rate before you treat either as the cheap option. India and Türkiye orders continued, 91 FR 1751
  • Quartz from an exempt country No safeguard on quartz made in Canada, Mexico, Australia, Colombia, Costa Rica, the Dominican Republic, El Salvador, Guatemala, Honduras, Israel, Nicaragua, Panama, Peru, Singapore or South Korea, or in the developing and Caribbean Basin countries listed in the note (Brazil, Indonesia and the Philippines among them). A Chinese slab finished there is still Chinese. HTSUS chapter 99, U.S. note 41(c)

India, Türkiye, Vietnam and Malaysia are not on the exempt list.

Which certificate answers which question

None of these is a building-code listing for the slab. They are what buyers actually get asked for: a food-zone listing, an emissions listing, and silica data for the shop that cuts it.

  • Food-zone surface for a restaurant, hotel kitchen or cafeteria NSF 51 A live NSF listing whose Facility line names the plant that makes your slabs. NSF food equipment listings
  • Low-emitting material for an indoor-air spec GREENGUARD A UL SPOT listing for the product family, held by this factory or tied to it in writing. UL SPOT
  • Fabrication in California Cal/OSHA silica The XRD crystalline silica result and SDS for each color, plus your fabricator's SB 20 attestation.
  • An NSF logo on a brochure proves nothing. NSF lists a product from a named facility, and the live listing has to show that facility.
  • GREENGUARD measures emissions only. It says nothing about silica, strength or food contact.
  • "Low silica" or "silica-free" without an XRD result is a sales line, not a test.
  • California has a proposed ban on engineered stone above a set silica level. Whether the board adopted it is unconfirmed as of 2026-10-18.

How to check each certificate

All certificate details below checked against the issuers and directories linked.

NSF/ANSI 51 food equipment materials

Lookup steps Ask for: The NSF listee name, trade name and the Facility line.

NSF (and other ANSI-accredited certifiers)

Proves
The surface material is certified for food-zone contact under NSF/ANSI 51 for the listed product and facility.
Does not prove
Silica content, stain or heat resistance, or that a different plant's slab is certified.
Required by
  • Spec or market: Optional for residential countertops.
  • Building code: Commercial food establishments: health departments require NSF/ANSI-certified or equivalent food-zone surfaces.
Ask for
The NSF listee name, trade name and the Facility line.
Look it up
NSF food equipment listings Search by: Product (model, trade name, type), Manufacturer, Facility location, Standard (NSF/ANSI 51).
  1. Search the NSF Food listings by manufacturer or trade name with standard NSF/ANSI 51.
  2. Check the Facility line matches the plant making your slabs.
  3. Re-open the live page; reject screenshots.
Red flags
  • An NSF 51 claim with no live listing.
  • A Facility line for a different plant.

Unconfirmed: Directory confirmed.

GREENGUARD and GREENGUARD Gold (VOC emissions)

Lookup steps Ask for: The certificate holder name and product family exactly as listed in UL SPOT.

UL Solutions

Proves
The listed product family met UL's chemical emissions limits for indoor air in testing, under the listed company's name.
Does not prove
Silica content, strength, stain resistance or food-zone suitability, or that a product made in a different plant is covered.
Required by
  • Spec or market: Voluntary. Asked for in project specs and indoor-air or green-building submittals.
Ask for
The certificate holder name and product family exactly as listed in UL SPOT.
Look it up
UL SPOT Search by: Standard (GREENGUARD), Manufacturer, Product. Certificate download needs a free registration.
  1. Search UL SPOT by manufacturer, filtered to the GREENGUARD standard.
  2. Check that the certificate holder is the factory, or that the brand on the listing has tied this factory to it in writing.
  3. Check the listed product family covers the colors you are buying, and the expiry date.
Red flags
  • A GREENGUARD logo with no SPOT listing.
  • A listing under a brand that does not cover the Chinese plant's products.

Cal/OSHA §5204 silica rules and SB 20 for engineered stone

Lookup steps Ask for: The crystalline silica percentage by XRD and the safety data sheet for the exact product.

Cal/OSHA, OSHSB, CDPH

Proves
Nothing about the slab itself. These rules govern how California fabricators cut and handle artificial stone above 0.1% crystalline silica.
Does not prove
That a 'low silica' slab is outside the rules. Ask for the measured crystalline silica percentage.
Required by
  • State: California: §5204 permanent rule effective 2025-02-05 (bans dry cutting). SB 20: employer attestations from 2026-07-01 and fabricator certification from 2027-01-01. A ban on artificial stone above 1% crystalline silica is proposed (discussion draft 2026-09-16); the board vote outcome is unconfirmed.
  • Federal: OSHA's general silica standards apply (29 CFR 1910.1053 / 1926.1153). No federal engineered-stone ban.
Ask for
The crystalline silica percentage by XRD and the safety data sheet for the exact product.
  1. Ask for an XRD crystalline silica result and the SDS for the product you are buying.
  2. If you sell into California, confirm your fabricator's SB 20 attestation and, from 2027-01-01, its certification.
Red flags
  • 'Silica-free' or 'low silica' claims with no XRD result.

Unconfirmed: §5204 and SB 20 dates confirmed; the proposed 1% ban vote is unconfirmed.

What a capable factory sends you

Documents and test reports, not names or badges.

We do not rank factories. Ask any factory on your shortlist for these. One that already ships quartz to the US has them on file, and the first two decide whether the duty math above applies to you.

  • The exporter and producer names exactly as they will appear on the commercial invoice. AD/CVD deposits attach to the exporter. Most Chinese exporters pay the China-wide rate.
  • If it claims its own AD/CVD rate: the Federal Register notice and the line that names the company. Only exporters named in the order notice, individually or on its separate-rate list, have their own deposit (see the table under "When AD/CVD reaches the order"). Any other name gets the China-wide rate.
  • For each color: the formulation by weight (silica, resin, pigment, other) and an XRD crystalline silica result. Silica share decides scope. Crystalline silica decides what a California fabricator has to do.
  • The SDS for each color. Your fabricator needs it under the silica rules.
  • The NSF listing (listee, trade name, Facility line) and the UL SPOT listing for GREENGUARD, or a plain statement that it holds neither. Food-service and indoor-air specs ask for them, and both name the plant.
  • Lab test reports for water absorption, flexural strength, and stain and chemical resistance, naming the product and the plant. A report for a different plant or color tells you nothing about your slabs.
  • Slab size, thickness, slab count and square meters per container. Your broker files the safeguard quota in square meters.
  • Where the slabs are pressed and cured, and whether any cutting or polishing happens outside China. Finishing in a third country does not change origin for the orders or the safeguard.

QC checkpoints

Where a quartz order goes wrong, in the order you can catch it.

  1. 1 Before the deposit
    • A full-size sample slab for each color, plus an offcut cut through to check color and pattern run through the body.
    • Formulation, XRD result and SDS on file for every color on the PO.
    • HTS line, invoice wording and the safeguard quota plan agreed with your broker.
  2. 2 During production
    • Thickness measured at several points across each slab against the tolerance written on the PO.
    • Color and veining compared with the approved sample under the same light.
    • Faces checked for pinholes, resin pooling, cracks and polishing marks.
  3. 3 Pre-shipment inspection
    • Slab count and total area checked against the packing list, since quota filing runs on square meters.
    • Edges and corners checked for chips. Cut-to-size tops measured against the shop drawings, sink cutouts included.
    • A-frame or crate packing, slabs separated and strapped, country of origin marked on each bundle.
  4. 4 On arrival
    • Every slab unpacked and inspected before it is cut. A claim after fabrication is hard to win.

MOQ and lead time

MOQ and lead time: no sourced data yet.MOQ moves with the number of colors, custom colors, non-standard slab sizes and cut-to-size tops instead of plain slabs; lead time with color approval rounds, new color development, edge and sink-cutout work on fabricated tops and the quota quarter you aim to enter in.

Questions buyers ask

Is there a tariff on quartz imports?
Yes. Quartz slabs and countertops from China pay 62.5% before AD/CVD while the Section 201 quota is open and 87.5% once it fills: base rate, Section 301, the forced-labor Section 301 and the safeguard. AD/CVD adds 371.47% for an exporter without its own rate. Quartz from India and Türkiye pays the safeguard plus its own AD/CVD. Quartz from a country on the exempt list pays no safeguard.
What is the HTS code for quartz countertops?
Agglomerated quartz slabs and countertops enter under 6810.99.00: statistical suffix .0020 for rectangular slabs at least 3 m long and 1.25 m wide, .0040 for everything else, including cut tops. Both pay 62.5% from China in quota. The written scope of the orders decides AD/CVD, not the HTS line, so a quartz product entered under another 6810 line still owes it.
Is quartz from China good quality?
Some is and some is not, and a quality claim tells you nothing without the formulation, an XRD result and lab reports for the plant making your slabs. For a US buyer the duty decides first: at 433.97% for an exporter without its own rate, the duty alone costs more than the slab, so most quotes never get as far as a quality check.
Is granite from China good quality?
It depends on the quarry and the block, not the country. Ask which quarry, check thickness, resin fill and any mesh backing, and get photos of the actual bundles before you pay the balance. On duty, Chinese granite (HTS 6802.93.00) pays 41.2% and no safeguard. A Federal Register search of ITA and USITC notices for "granite" on 2026-10-18 found no AD/CVD order on it.
