1Overview

  • Destination duty: Free (General, same on all 2 lines) — No preferential agreement with China — the basic / MFN rate applies.
  • Federal VAT / GST: None — The US has no federal VAT. State sales tax is not charged at import.
  • This code covers: Other audio-frequency electric amplifiers
  • Additional tariffs: about +37.5% — Section 301 forced-labor duty (China) (Re-verified 2026-09-15: no change.) · Section 301 China Lists 1-4A (Re-verified 2026-09-15: no change.)
  • Regime to watch: US duty-free de minimis suspended for all countriesSince 2025-08-29 Executive Order 14324 has suspended duty-free de minimis entry for shipments from every country. Parcels are now dutiable and need an entry with HS classification and origin, which raises the difficulty of small consignments.federalregister.gov

Key points

  • De minimis is suspended indefinitely: non-postal modes since 2026-06-24, international mail since 2026-07-24. The US$800 duty-free entry no longer exists.
  • No federal VAT or GST. State sales or use tax is a separate matter handled after import, not at the border.
  • US$2,500 separates informal from formal entry. Mail shipments up to US$2,500 in HTSUS chapters 1-97 may use the new postal informal entry process, with duty due by the 7th day of the month following arrival.
  • The importer of record may self-file in ACE, but formal entries require a customs bond, and ocean cargo also requires an Importer Security Filing (ISF 10+2) at least 24 hours before loading.
  • The Section 122 surcharge ended on 2026-07-24, and a Section 301 forced-labour action covering 60 economies took effect the same day. Additional duties appear as HTSUS Chapter 99 lines, so check what is in force on your entry date.

Key points on the origin side

  • Customs registration as consignor is required before exporting; foreign trade operator registration was abolished from 2022-12-30.
  • Most goods carry no export duty; only the limited list in the Import and Export Tariff carries an export duty or provisional export rate.
  • Exports are zero-rated or exempt for VAT, and a qualifying exporter claims the refund at the rate published for the commodity code.
  • Check the regulatory condition code on the commodity code to see whether an export licence, a dual-use licence (State Council Decree 792) or statutory inspection applies. MOFCOM and GACC publish the dual-use licensing catalogue each year.
  • Certificates of origin are issued by customs or CCPIT and are what the buyer uses to claim preference at destination.
  • Statutory inspection is governed by the Catalogue of Import and Export Commodities Subject to Compulsory Inspection (the 法检 catalogue), shown as customs supervision condition A (import inspection) / B (export inspection) on the commodity code and adjusted by GACC announcement from time to time (latest adjustment: GACC Announcement 2026 No. 97, effective 2026-07-16). Check the supervision conditions of your code before declaring.

Caveats

  • These layers are defined at the 8- or 10-digit HTS line. An HS6 code (851840) can only give the general picture.
  • At least one of these duties is being challenged in court. It is being collected today, but that can change.
  • The US$800 de minimis exemption is suspended, so low-value parcels are dutiable too; statutory repeal follows on 2027-07-01.
  • Duty is not the whole bill: MPF and (for ocean freight) HMF apply on top, and are not included here.
  • Information only, as of 2026-09-15. The HTSUS Chapter 99 notes and CBP CSMS guidance in force on the entry date control — verify with CBP or a licensed customs broker.
De minimis status

US $800 de minimis exemption

Suspended for all countries from 2025-08-29 and made indefinite by CBP interim final rules of 2026-06-24 (non-postal immediately, international mail from 2026-07-24). On 2026-08-13 the Court of International Trade rejected a challenge to the suspension, so it now stands on firmer ground. Statutory repeal follows on 2027-07-01 under the One Big Beautiful Bill Act, and as at the 2026-09-09 re-check no legislation has moved that date. The $100 gift and $200 accompanied-articles exemptions survive. Goods carrying a Chapter 99 duty cannot use the postal informal-entry route.

Information, not advice. US additional duties change often and are under litigation. What you actually pay is set by the HTSUS Chapter 99 notes and CBP CSMS guidance in force on the entry date — verify with CBP or a licensed broker.

As of: 2026-09-15

  • · The United States has no federal value-added or goods-and-services tax. Customs collects duty and fees only.
  • · Merchandise processing fee: 0.3464% of the entered value on formal entries, with a minimum and maximum re-indexed to inflation each fiscal year. For FY2026 (through 2026-09-30) the range is US$33.58 to US$651.50; for FY2027 (from 2026-10-01) it is US$34.58 to US$670.86. Informal entries pay a flat amount instead — US$2.77, 8.30 or 12.45 in FY2027.
  • · Harbor maintenance fee: 0.125% of the value on cargo arriving by vessel.
  • · State sales or use tax may apply to the onward sale or use of the goods and is administered by state revenue departments, not by CBP.
  • · Chapter 99 additional duties are added to the ordinary rate. As of 2026-09 that means Section 232 measures and the Section 301 forced-labour action effective 2026-07-24; the Section 122 surcharge ended on 2026-07-24. Verify what applies on the entry date.

6Procedure

  1. Pre-loading filingsThe importer or its agent files the Importer Security Filing (ISF 10+2) at least 24 hours before the cargo is loaded onto the vessel, and the carrier files its advance cargo manifest on the same 24-hour timeline.
  2. Entry filingCBP Form 3461 is filed in ACE, generally up to five days before arrival. Entry must be made within 15 calendar days of arrival, otherwise the goods are moved to a General Order warehouse.
  3. Review, examination and agency holdsCBP may select the shipment for document review, X-ray or a physical examination, and a partner government agency such as FDA, USDA or CPSC may place its own hold.
  4. ReleaseOnce CBP and any agency holds are cleared, the goods are released and may leave the port.
  5. Entry summary and paymentCBP Form 7501 is filed within 10 working days of release with duty, merchandise processing fee and harbor maintenance fee, paid entry by entry or on a periodic monthly statement.
  6. LiquidationCBP fixes the final duty at liquidation, normally within 314 days of entry. Post-summary corrections and protests have their own separate deadlines.
  1. Advance manifestThe air carrier transmits its advance cargo information before arrival. The Importer Security Filing does not apply to air cargo.
  2. Entry filingCBP Form 3461 is filed in ACE, commonly before the aircraft lands, so that release can follow shortly after arrival.
  3. Review and agency holdsCBP and partner government agencies review the entry and may examine the shipment at the airport cargo facility.
  4. Release and deliveryAfter release the goods leave the bonded air cargo facility.
  5. Entry summary and liquidationCBP Form 7501 and duty follow within 10 working days of release, then liquidation as for ocean cargo.
  1. Advance dataThe express consignment operator or the postal operator transmits shipment data to CBP before arrival.
  2. EntrySince 2026-06-24 low-value goods can no longer be released from the manifest. Express shipments are entered as informal entries, normally Entry Type 11, and anything above US$2,500 requires a formal entry.
  3. Mail shipmentsSince 2026-07-24 mail shipments valued at US$2,500 or less and classifiable in HTSUS chapters 1 to 97 may use the postal informal entry process, filed by a licensed customs broker or by the owner or purchaser, with a basic importation and entry bond in place.
  4. Duty assessment and paymentDuty and fees are calculated on the declared value. Express operators normally advance the duty and bill the buyer; under the postal process duty is due no later than the 7th day of the month following the package's arrival.
  5. Agency screening and deliveryFood, cosmetics, drugs, radio devices and children's products still require their agency data, and goods subject to quota, antidumping or countervailing duties, Chapter 98 or 99 duties, or a free trade agreement claim are excluded from the postal informal process.
  1. Declaration on arrivalTravellers declare everything acquired abroad, on CBP Form 6059B or its electronic equivalent, and answer the CBP officer's questions at the port of entry.
  2. Personal exemptionsReturning U.S. residents generally have a personal exemption of US$800. Non-residents' accompanied personal and household articles of US$200 or less remain exempt under 19 U.S.C. 1321(a)(2)(B).
  3. Commercial merchandiseGoods carried for resale are not covered by a personal exemption. They require an informal or formal entry like any other import, and partner government agency rules still apply.
  4. PaymentDuty on declared goods above the exemption is paid at the port of entry before the traveller leaves the customs area.
