Customs Specialist Qualification Examination cheat sheet

The Customs Law establishes four core duties of the customs administration: supervision and control of inbound/outbound goods and means of transport, collection of customs duties and taxes, anti-smuggling enforcement, and compilation of customs statistics.

Declarants must register with customs before filing; unregistered entities may entrust a registered customs broker, and the broker bears joint liability with the principal for declaration accuracy.

Duty-payer liability attaches at the time of declaration; where goods are released before duty assessment, customs may issue a duty memorandum and the payer must settle within the statutory period (commonly 15 days from issuance).

Customs may exercise inspection, examination of documents, questioning, and investigation powers; refusal to cooperate can trigger compulsory enforcement including seizure of goods and bank account inquiries.

Administrative penalties for declaration errors distinguish between technical errors (correctable, low or no fine) and smuggling or evasion (confiscation of goods plus fines of a percentage of the duty evaded or goods value).

Appeal path: a written administrative reconsideration application to the superior customs authority or the same-level people's government, then administrative litigation in the people's court if the reconsideration decision is unsatisfactory.

Smuggling definitions include concealment, false declaration, and unlicensed import/export of restricted goods; the customs anti-smuggling bureau handles criminal cases transferred to the procuratorate.

Customs supervision extends over a defined period after release (bonded goods, temporarily imported goods, specific-duty-reduced equipment), during which the goods remain subject to customs control and may not be disposed of without approval.

Trade policy instruments include tariffs, tariff-rate quotas (TRQ), import/export licenses, automatic licensing, prohibitions, anti-dumping and countervailing duties, and safeguard measures.

TRQ administration splits a quota into an in-quota rate (lower) and an out-of-quota rate (higher); quota allocation is typically by application and historical performance, and unused quota may be reallocated.

Anti-dumping duties apply when dumped imports cause material injury to the domestic industry; the duty equals the dumping margin, and the measure is time-limited with periodic sunset review.

Safeguard measures are emergency, non-discriminatory restrictions applied to fair trade when imports surge; they require compensation or consultation with affected trading partners.

Export controls restrict dual-use items, military items, and specified technologies; exporters must obtain a license before shipment and may face end-user/end-use certification requirements.

Rules of origin for preferential trade agreements determine eligibility for conventional tariff rates; non-preferential origin rules apply for MFN rates, trade statistics, and quota administration.

Customs classification, valuation, and origin are the three pillars of tariff application; errors in any pillar change the duty payable and can trigger penalties.

Trade remedy investigations require standing by the domestic industry, evidence of injury, and a causal link; provisional measures are time-limited pending final determination.

Standard import declaration flow: electronic data entry, customs review, duty payment, inspection (if selected), release, and pickup; the declaration form must be filed within the statutory period after arrival (typically 14 days for imports).

Required documents typically include the customs declaration form, commercial invoice, packing list, bill of lading or airway bill, contract, certificate of origin, and any license or inspection certificate.

Declaration elements include consignee/consignor, means of transport, trade mode, nature of goods, HS code, quantity, unit price, total value, origin, and destination.

Advance declaration is permitted for imports; goods may be released before duty payment if a guarantee is provided, with duty settled within the specified period.

Amendments and cancellations are allowed for clerical errors or changed circumstances before release, subject to customs approval; post-release corrections require formal application and may incur fees.

Inspection selection is risk-based: green channel (document review only), yellow channel (document review plus inspection), red channel (full inspection); risk profiles drive channel assignment.

Transit goods require a customs transit document with a specified route and time limit; the carrier is responsible for the goods until arrival at the destination customs office.

Electronic declaration through the single window is standard; paper documents may be required for verification, and data must match the underlying commercial documents exactly.

The HS is organized into 21 sections and 97 chapters (Chapter 77 reserved); classification proceeds from section/chapter notes to heading (4 digits) to subheading (6 digits) to national tariff lines.

General Interpretative Rules (GIR) order: GIR 1 (heading text and notes), GIR 2 (incomplete/unassembled goods, mixtures), GIR 3 (specific vs. general, essential character, last in numerical order), GIR 4 (most akin), GIR 5 (packing), GIR 6 (subheading comparison).

GIR 3(a): the heading providing the most specific description prevails over a general description; GIR 3(b): essential character for mixtures and sets; GIR 3(c): last in numerical order when 3(a) and 3(b) fail.

Wholly obtained criteria apply to agricultural and mineral products; substantial transformation for manufactured goods is tested by change in tariff heading (CTH), value-added percentage, or specific process rules.

Preferential origin requires direct consignment and documentary proof (certificate of origin); transshipment through third countries must be justified and documented.

Cumulative rules allow materials originating in partner countries to count as originating; bilateral cumulation is common in free trade agreements.

De minimis thresholds allow a small percentage of non-originating materials without losing origin; percentages vary by agreement and product.

Classification disputes are resolved by advance rulings, which bind customs for a stated period and provide certainty for importers.

Customs value is primarily transaction value: price actually paid or payable, adjusted to include commissions (except buying commissions), royalties as a condition of sale, packing costs, and assists, and to exclude post-import costs.

When transaction value is unavailable, the fallback sequence is: identical goods, similar goods, deductive value, computed value, and finally the reasonable-means method (Article 7).

Duty payable = customs value × applicable tariff rate; VAT base = customs value + duty + consumption tax (where applicable); consumption tax applies to specified goods such as alcohol, tobacco, and luxury items.

Preferential rates apply when a valid certificate of origin is presented; MFN rates apply absent preferential proof; general rates apply to non-WTO-origin goods where applicable.

Currency conversion uses the customs-published exchange rate on the declaration date (or the rate in effect for the applicable period).

Duty reduction/exemption categories include statutory exemptions (e.g., certain government goods), temporary exemptions, and specific-duty-reduced equipment subject to supervision.

Late payment incurs a surcharge (commonly 0.05% per day of the overdue duty); underpayment discovered later may be recovered within the statutory limitation period.

Valuation disputes can be challenged through administrative reconsideration; customs may require a price inquiry or refer to the valuation database when declared value appears low.

Prohibited goods cannot be imported/exported at all; restricted goods require a license or permit; automatic licensing goods require registration but not discretionary approval.

Import licenses are typically valid for a stated period and may be extended; the license must match the goods, quantity, and consignee, and cannot be transferred without approval.

Quarantine requirements apply to plants, animals, food, and biological materials; a phytosanitary or health certificate and pre-shipment inspection may be required.

Dual-use items are controlled for national security and non-proliferation; exporters must obtain an export license and may need end-user statements.

Sanitary and phytosanitary (SPS) measures must be based on scientific evidence and international standards; emergency measures are time-limited and subject to review.

Inspection and quarantine authorities may sample, detain, return, or destroy goods that fail requirements; the importer bears the cost of treatment or destruction.

Licensing administration uses catalogues that are updated periodically; importers must confirm the current catalogue before shipment to avoid detention.

Certificate of origin, inspection certificate, and quarantine certificate are commonly required supporting documents for restricted goods.

Bonded warehouses store imported goods without duty payment until they enter the domestic market; duty is assessed at the rate in effect on the date of withdrawal.

Processing trade (import materials processing and assembly) allows duty-free import of materials that are re-exported after processing; the enterprise must register the processing trade contract and maintain a processing trade manual.

Processing trade enterprises must balance import and export quantities within the approved processing period; surplus or shortfall requires customs approval and duty settlement.

Bonded zones and comprehensive bonded zones are special customs supervision areas with tax deferral, simplified procedures, and permitted domestic sales subject to duty.

Bonded logistics centers and export processing zones offer different scopes: logistics centers focus on storage and distribution, export processing zones on manufacturing for export.

Goods entering a special supervision area from overseas are bonded; goods entering from the domestic market are treated as exports and may qualify for export tax rebates.

Customs supervision period for bonded goods ends upon export, domestic sale with duty payment, or destruction with approval; disposal without approval triggers penalties.

Annual verification and reconciliation of bonded inventory are mandatory; discrepancies must be reported and settled within the prescribed period.

Customs audit types include routine audit, special audit, and follow-up audit; customs may audit on-site or require self-inspection and document submission.

Risk management drives audit selection; high-risk profiles include low declared value, frequent classification changes, and unusual trade patterns.

Compliance programs should include internal classification reviews, valuation documentation, origin records, and periodic self-audits.

Penalties range from warnings and fines to confiscation of goods and suspension of declaration privileges; smuggling may lead to criminal liability.

Voluntary disclosure of errors before customs discovers them can reduce or waive penalties; the disclosure must be timely and complete.

Administrative reconsideration must be filed within the statutory period (commonly 60 days from knowledge of the decision); litigation follows if reconsideration is unsatisfactory.

Customs may impose guarantees or suspend release pending investigation; the enterprise can apply for review of the suspension decision.

Recordkeeping requirements mandate retention of declaration documents for a specified period (commonly 3 years); failure to retain records can result in fines.

Customs brokers and declarants must act with integrity, accuracy, and confidentiality; false statements can result in license suspension or revocation.

Conflict of interest must be disclosed; practitioners may not accept benefits that influence declaration accuracy or classification decisions.

Practitioners must maintain competence through continuing education and stay current on tariff, valuation, and origin rules.

Client confidentiality applies to commercial data, pricing, and trade secrets; disclosure is permitted only when required by law or with consent.

Practitioners must verify the accuracy of documents provided by clients and may not knowingly file false declarations.

Professional liability may arise from negligent classification, valuation, or origin advice; practitioners should document advice and maintain records.

Ethical obligations include avoiding facilitation of smuggling, fraud, or evasion, and reporting suspicious transactions to compliance officers.

Practitioners must comply with anti-corruption laws and may not offer or accept improper payments to customs officials.
