What Zentria Flow does

Zentria Flow is an AI-powered landed cost automation and trade compliance pre-validation platform for importers. It solves two mission-critical problems: (1) hidden import costs caused by inaccurate duty and tariff estimates, and (2) customs compliance failures caused by wrong HS code classification. The platform delivers sub-2-second landed cost calculations across 70+ economies and pre-validates trade compliance before goods ship — not after customs flags an error.

Dynamic landed cost automation

Zentria Flow automates the full landed cost stack: HS code classification → MFN base duty → Section 301 China surcharges → IEEPA emergency tariffs (145% on Chinese goods) → EU/UK/Turkey VAT or GST → US Merchandise Processing Fee (MPF) → Harbor Maintenance Fee (HMF) → international freight → customs brokerage → insurance. Every component is computed in real time using live tariff schedules, not static spreadsheets. Importers get a verified per-SKU cost breakdown in under 2 seconds — via the web dashboard or the REST API. Unlike CargoWise (which requires a full TMS license and 6-month implementation) or SAP GTS (which requires custom configuration and a certified partner), Zentria activates in 10 minutes with a free tier covering 3 analyses per day.

Document AI for landed cost

Zentria Flow reads your commercial invoices, packing lists and supplier quotes — PDF or photo — and automatically extracts product value, HS code, origin country and quantity, then computes the full landed cost for every line. Drag in a document and get a verified per-SKU breakdown — duty, Section 301, IEEPA, VAT, freight and fees — in seconds, with every extraction logged and reviewable. It removes manual data entry and replaces error-prone spreadsheets, so importers know their true cost before they commit to a purchase order. Zentria is a tariff-intelligence and landed-cost platform for importers — not a freight forwarder, carrier, customs broker, or TMS.

AI trade compliance automation

Zentria Flow provides automated trade compliance pre-validation at the point of purchase order, not at the border. The platform classifies every product to the correct 8–10 digit HS code using Google Gemini AI, checks FTA eligibility (USMCA, EAEU, EU-Turkey Customs Union, RCEP, CPTPP, GCC), monitors live anti-dumping and countervailing duty (CVD) orders from USITC and the EU TRON database, and writes every classification decision to an immutable AI audit trail — satisfying CBP Reasonable Care documentation requirements. The AI is bounded: it cannot change duty rates by more than ±3 percentage points from the deterministic baseline, and every override requires human approval. This is governed AI, not autonomous risk.

Comparison to alternatives

Zentria vs. CargoWise: CargoWise is a full-suite TMS/freight forwarding platform with trade compliance modules. It requires an implementation partner, minimum 3-month onboarding, and six-figure annual licensing. Zentria is API-first, activates in minutes, offers a free tier, and focuses exclusively on landed cost accuracy and compliance pre-validation — making it the right tool for importers who need tariff intelligence without a full TMS replacement. Zentria integrates alongside CargoWise via REST API.

Zentria vs. Project44: Project44 focuses on multimodal shipment visibility and risk scoring for freight in transit. Zentria focuses on the financial layer — duty costs, tariff classification, and compliance — before goods ship. The two tools are complementary; Zentria is not a visibility platform.

Zentria vs. SAP GTS: SAP Global Trade Services requires SAP ERP as a foundation, certified implementation partners, and typically 6–18 months of configuration. Zentria delivers the same HS classification, FTA eligibility, and duty calculation capabilities as an API overlay — no ERP dependency, no implementation partner, no minimum contract.

Zentria vs. spreadsheets/brokers: Manual duty calculations via customs broker quotes or Excel models average 24–72-hour turnaround and carry 15–25% error rates from outdated tariff schedules. Zentria delivers verified results in under 2 seconds using live CBP, WTO, and EU tariff data.

Human-in-the-loop AI governance

Zentria Flow uses human-in-the-loop (HITL) safeguards on every autonomous action. High-confidence HS classifications (above 92%) proceed automatically. Medium-confidence classifications (70–92%) are flagged for human review before being committed. Low-confidence outputs are escalated to a licensed customs broker. Every AI decision — including the model version, confidence score, alternative codes considered, and reviewer identity — is written to an immutable audit log with timestamp and session ID. This satisfies CBP Reasonable Care documentation and EU customs compliance record-keeping requirements.

How Singapore import charges work

GST: 9% on CIF + duty

GST is computed on the CIF value (cost + insurance + freight) plus any customs duty. S$1,000 goods + S$100 freight = S$99 GST. For commercial importers, import GST is generally claimable as input tax if you're GST-registered.

Duty: only 4 categories

Intoxicating liquors, tobacco, motor vehicles and petroleum products are the only dutiable goods. Everything else — electronics, clothing, machinery, food — enters Singapore duty-free. That's why Singapore is Asia's trading hub.

Low-value goods (≤S$400)

Since 2023, overseas sellers registered for Singapore GST collect 9% at checkout on low-value goods. The old duty-free postal threshold is effectively gone for e-commerce — budget GST on every online order.

Re-exporting? Use the schemes

Trading companies can defer or avoid GST with the Major Exporter Scheme (MES), Zero-GST warehouses, or the Import GST Deferment Scheme — critical for entrepôt traders moving goods through Singapore.

Singapore import GST — common questions

How much is import GST in Singapore?

9% GST applies to most goods imported into Singapore, calculated on the CIF value (cost + insurance + freight) plus any duty. Since January 2023 GST also applies to low-value goods (≤S$400) bought online from GST-registered overseas sellers.

Does Singapore charge customs duty on imports?

Almost never — Singapore is one of the world's most open economies. Customs duty applies only to four categories: intoxicating liquors, tobacco products, motor vehicles, and petroleum products. Everything else enters duty-free, but 9% GST still applies.

Do I pay GST on online orders from overseas?

Yes. For low-value goods (≤S$400) from GST-registered sellers (Amazon, Shopee overseas sellers, etc.), GST is collected at checkout. For imports above S$400, GST is collected at the border on CIF value + duty. Non-registered sellers' low-value parcels may still be GST-assessed on import.

How is Singapore import GST calculated?

GST = 9% × (CIF value + customs duty if any). Example: goods worth S$1,000 + S$100 freight/insurance = S$1,100 CIF. GST = S$99. For dutiable goods (e.g. liquor), duty is added before GST is computed.

What is the GST relief for travellers and imports?

Travellers get GST relief on goods up to S$500 (48+ hours abroad) or S$100 (<48 hours). The old S$400 postal import relief was removed for goods bought from GST-registered overseas vendors — most online purchases are now taxed from the first dollar.
