14. E-Commerce and International Trade: Practice and Policy

Teaching rewrite of cross-border e-commerce practice and policy. Pedagogical summaries only — not legal, tax, or compliance advice. E-commerce rules change fast (VAT schemes, de minimis thresholds, data-transfer frameworks); treat dates and thresholds as points to verify, not settled facts.

Introduction​

The internet lets a ten-person company sell to customers in fifty countries — and buy from suppliers just as far away. But cross-border online selling turns problems that were handled once per container into problems handled once per parcel: duties, VAT, customs codes, payment fraud, data protection, and which country’s law applies to an electronic contract.

This lesson covers:

  • Market categories (B2C, B2B, C2C) and why measurement is hard
  • Landed cost: who pays duties and taxes, and the DDP vs “duties for buyer” choice
  • Payments, fraud, and chargebacks
  • Customs classification for online sellers
  • Legal recognition of electronic contracts, documents, and signatures
  • Data protection, privacy, spam, and information compliance
  • Trade policy: WTO, the e-commerce moratorium, and the forums shaping internet governance

Assumptions. A small or mid-sized seller shipping physical goods ordered online to buyers in other countries; digital services are mentioned where policy differs.

14.1 The cross-border e-commerce market​

CategoryWho tradesExample
B2CBusiness → consumerWeb shop shipping parcels abroad
B2BBusiness → businessOnline procurement portal, wholesale marketplace
C2CConsumer → consumer (via a platform)Online marketplaces for second-hand goods

Measurement has always been patchy — agencies and research firms define “e-commerce” differently, so figures are not comparable across sources. The trend, however, is clear: online buying has grown from a minority activity in the 2000s to a mainstream channel, and cross-border parcels have become a major share of postal and express volumes. Check UNCTAD, OECD, or national statistics for current figures.

14.2 Landed cost, Incoterms®, and taxes​

A domestic web shop quotes one price. A cross-border shop needs a different landed cost (goods + shipping + duties + taxes) for every destination — and buyers want to see it before they order.

Two basic choices​

Duties paid by seller (DDP)Duties paid by buyer (any other Incoterm, e.g. CPT, CIP, DAP)
Buyer experienceParcel arrives, nothing more to payCarrier demands duties and taxes before releasing the parcel
Seller’s riskEstimating duties and taxes wronglyBuyer refuses delivery — seller pays return shipping and loses the sale
NeedsAccurate duty/tax calculation and registrationsClear disclosure at checkout
Incoterms® edition note

Older guides mention DDU; it was removed in Incoterms® 2010. The current equivalent idea is DAP (delivered, buyer clears import and pays duties).

VAT on low-value imports​

Many countries used to exempt small parcels (a de minimis threshold) from duty and VAT. That is changing:

  • EU (since July 2021): VAT is due on all imported goods; the old small-value VAT exemption was abolished. Sellers can register in the Import One-Stop Shop (IOSS) to charge VAT at checkout on consignments up to EUR 150 so parcels clear without extra charges. The EU customs reform also moves to remove the EUR 150 duty exemption — check the timetable.
  • Several other markets (e.g. the UK, Australia, Norway, New Zealand) require foreign sellers or marketplaces to collect VAT/GST on low-value goods at the point of sale.
  • The U.S. long had a high de minimis (USD 800) but has suspended or narrowed it — verify the current rule before quoting.

Worked example: landed cost for one parcel​

Goods USD 100, shipping USD 20, insurance USD 1. Destination charges duty of 5% on the CIF value and VAT of 15% on (CIF + duty). (Illustrative rates.)

ItemCalculationUSD
CIF value100 + 20 + 1121.00
Duty5% × 1216.05
VAT base121 + 6.05127.05
VAT15% × 127.0519.06
Landed cost121 + 6.05 + 19.06146.11

Selling at “USD 100 + shipping” and leaving the buyer to pay ~USD 25 at the door invites refusals. Selling DDP at about USD 146 removes the surprise — if the estimate is right.

14.3 Payments, fraud, and chargebacks​

  • Cards (Visa, Mastercard, American Express…) dominate, but many markets prefer local methods (domestic card schemes, bank transfers, wallets, buy-now-pay-later).
  • Payment service providers / wallets (e.g. PayPal-type services and acquirers specialising in cross-border processing) accept payment for the seller, absorb data-security burdens, and offer local methods. Read their seller-protection rules carefully — protection usually depends on proof of delivery.
  • Strong customer authentication (e.g. 3-D Secure; mandatory for many EU card payments under PSD2) shifts fraud liability away from the merchant when used.

Fraud and chargebacks​

Cross-border orders carry higher fraud rates than domestic ones, so merchants screen and reject more of them.

A chargeback is a reversal the cardholder’s bank initiates on the cardholder’s behalf — for fraud (“I didn’t buy this”) or disputes (“never arrived”, “not as described”). The merchant loses the money plus a fee unless it wins the dispute with evidence (delivery confirmation, authentication, correspondence).

Worked example: the cost of chargebacks​

1,000 orders a month, average USD 80; chargeback rate 1%; fee USD 20 per chargeback; merchant wins 40% of disputes.

ItemCalculationUSD
Chargebacks1% × 1,00010
Revenue lost (disputes lost)10 × 60% × 80480
Fees (charged on all chargebacks)10 × 20200
Monthly cost680 (0.85% of sales)

Reducing the rate to 0.5% (better screening, authentication, tracking) roughly halves that cost.

14.4 Customs classification for online sellers​

Every product crossing a border needs a Harmonized System (HS) code (details in Lesson 16). For online sellers:

  • The code sets the duty rate, decides preferential treatment under free-trade agreements, and goes on the commercial invoice and certificate of origin.
  • With thousands of SKUs, classify only what you actually export — then make classification of new products part of the listing process.
  • Small sellers often rely on carriers, marketplaces, or classification software — but the seller remains responsible for the declaration.

14.5 Law for electronic contracts, documents, and signatures​

UNCITRAL instruments​

InstrumentWhat it does
Model Law on Electronic Commerce (1996) and on Electronic Signatures (2001)Templates many countries used for domestic e-commerce laws
Convention on the Use of Electronic Communications in International Contracts (2005; in force since 2013)Electronic messages satisfy form requirements of other conventions; rules on location of parties, time and place of dispatch and receipt, invitations to offer; respects party autonomy
Model Law on Electronic Transferable Records (MLETR) (2017)Lets electronic records act like bills of lading, bills of exchange, and promissory notes — adopted by a growing number of jurisdictions (e.g. the UK’s Electronic Trade Documents Act 2023)

ICC and industry tools​

  • ICC eTerms (2004): short clauses parties incorporate to confirm they intend a binding electronic contract.
  • eUCP and eURC: supplements to UCP 600 and URC 522 for electronic presentation (see Lesson 9; now eUCP 2.0).
  • Digital trade platforms — e.g. Bolero and other electronic bill of lading and trade-document platforms — replace paper document flows among traders, carriers, and banks. (Earlier pioneers such as TradeCard were absorbed into larger supply-chain networks.)

Electronic signatures​

TermMeaning (as used here)
Electronic signatureAny data in electronic form, attached to or logically linked with a message, used to identify the signer and show approval
Digital signatureA specific cryptographic technique (public/private keys) that proves who signed and that the message was not altered

ICC’s policy recommendations for signature laws: freedom of contract, legal acceptance across borders, technology neutrality, no localisation or local-partner requirements, and competition among authentication providers. Major frameworks today include the EU’s eIDAS regulation and the U.S. E-SIGN Act and UETA.

Information compliance​

Rules from many fields (tax, anti-money laundering, sanctions, consumer protection, data protection, security) dictate how companies use technology. They sometimes conflict — e.g. one country restricts sending personal data abroad while another requires screening customers against watch lists — and may be hard to find. Map the obligations per market before launching.

14.6 Data protection, privacy, and spam​

From the 1995 Directive to the GDPR​

The EU Data Protection Directive 95/46/EC was replaced in 2018 by the General Data Protection Regulation (GDPR), which applies to non-EU sellers that target EU customers. Personal data may leave the EU only with a legal basis, for example:

Transfer toolHow it works
Adequacy decisionThe Commission recognises a country’s protection as adequate (e.g. the EU–US Data Privacy Framework for certified U.S. companies)
Standard Contractual Clauses (SCCs)Approved contract terms between exporter and importer of data
Binding Corporate Rules (BCRs)Approved group-wide rules for transfers within a multinational (ICC published a standard BCR application form)

Other major regimes include APEC’s Cross-Border Privacy Rules, Brazil’s LGPD, China’s PIPL, and U.S. state laws.

ICC’s privacy principles for governments​

  1. Flexible, responsive protection — accept self-regulation and privacy-enhancing technology
  2. Educate the public
  3. Cooperate internationally; avoid needless barriers to cross-border data flows
  4. Endorse model contracts, codes of conduct, seal programmes

Spam​

No single legal definition exists; ICC uses “spam” for harmful, fraudulent, malicious, misleading or illegal messages, generally sent in bulk. Defence is a toolkit: laws (many require consent or easy opt-out for marketing email), industry codes, and technical filters and authentication.

14.7 Trade policy and internet governance​

WTO and digital trade​

  • WTO members have never settled whether electronically delivered products are goods (GATT: market access and national treatment) or services (GATS: obligations only where a country has committed).
  • Since 1998, members have repeatedly renewed a moratorium on customs duties on electronic transmissions — under political pressure at each Ministerial Conference.
  • A plurilateral Joint Statement Initiative on e-commerce has negotiated rules on e-signatures, paperless trading, consumer protection, and spam among a large group of members.

ICC’s business objectives: build e-business infrastructure without barriers; implement and extend telecom and IT services liberalisation (and eliminate duties on IT products, as in the WTO Information Technology Agreement); develop trade in goods and services via e-business; and protect IP online through TRIPS and the WIPO “internet treaties” (Copyright Treaty, Performances and Phonograms Treaty).

Pick an answer to see if you are right.

Takeaways​

Remember
  • Cross-border e-commerce moves duties, VAT, fraud, and data rules down to every parcel
  • Show landed cost: DDP removes doorstep surprises; duties-for-buyer risks refusals
  • Low-value import exemptions are shrinking — EU IOSS, VAT collection by sellers/marketplaces elsewhere
  • Manage fraud with authentication and evidence; price in chargebacks
  • Classify products before listing them for export
  • E-contracts and e-documents are legally supported (UNCITRAL convention, MLETR, eUCP, e-signature laws)
  • GDPR governs EU personal data; transfers need adequacy, SCCs, or BCRs
