TOEIC Link Logistics and Supply Chain Vocabulary: The 140-Word Cluster Behind Every Shipment, Customs, and Inventory Passage

Logistics did not used to be a TOEIC Link priority cluster. Five years ago it was a corner of the manufacturing cluster, sharing space with procurement and quality. The post-pandemic restructuring of global trade pushed logistics into a top-five industry cluster by Part 7 share, and the rise of e-commerce push the tail of operational vocabulary — last-mile delivery, returns processing, reverse logistics — directly into the test bank. Open any 2025 or 2026 TOEIC Link practice form and you will see at least three Part 7 single-passage items and one Part 4 announcement set in a warehouse, customs office, freight forwarder, or distribution center.

This is the focused 140-word cluster organized by the order-to-delivery flow — order intake, fulfillment, transit, customs and last-mile, post-delivery — because that is the structural shape ETS uses when it builds logistics items. Memorize each stage as a unit and you will recognize the passage type before you read the question stem.

Why logistics is now a top-five cluster

Three structural forces are pushing logistics content into a larger share of the test.

Reason 1 — Logistics documents are highly templated and easy to convert into items. A bill of lading, a customs declaration, a freight quote, a delivery exception notice. Each follows a fixed shape that ETS can adapt with minor edits, and the visual form (line-item table, status grid, exception code list) is preserved in the test booklet to test both vocabulary and scanning skills.

Reason 2 — Logistics vocabulary now overlaps with customer-facing roles. Five years ago, logistics English was the language of warehouse managers and freight forwarders. Today, customer-success teams, account managers, and procurement teams all need to read shipment exceptions and explain delivery delays. ETS deliberately weights vocabulary that has spread out from a specialist function into general workplace use.

Reason 3 — Logistics items overlap with customer service, manufacturing, and finance. Roughly 30 words in this cluster also appear in the TOEIC Link customer service vocabulary cluster (delivery exceptions, refunds for non-delivery), 25 words overlap with TOEIC Link manufacturing and operations (inventory and warehousing), and 15 words overlap with TOEIC Link finance and accounting (incoterms, freight cost allocation). Mastering logistics unlocks part of three adjacent clusters at no extra cost.

The 140-word cluster, organized by the order-to-delivery flow

The cluster below is grouped by where the document sits in the order-to-delivery flow, not by part of speech. Memorize each group as a unit. Collocations are listed inline because the collocation, not the bare word, is what gets tested.

Stage 1 — order intake (≈22 words)

This is the vocabulary of receiving and confirming an order. ETS uses this group for Part 7 order-confirmation emails and Part 4 voicemails returning an order inquiry.

  • purchase order (PO) / issue a PO, cancel a PO, amend the PO
  • order acknowledgment / send an order acknowledgment, await acknowledgment
  • lead time / standard lead time, expedited lead time
  • stock / in stock, out of stock, low stock, replenish stock
  • inventory / available inventory, on-hand inventory, allocated inventory
  • backorder / on backorder, place a backorder, clear the backorder
  • SKU / SKU number, SKU-level detail
  • MOQ / minimum order quantity, meet the MOQ
  • freight quote / request a freight quote, accept the freight quote
  • incoterms / agree on incoterms, FOB, CIF, DAP, DDP
  • terms of sale / standard terms of sale, special terms of sale
  • payment terms / net 30, net 60, payment in advance

ETS uses backorder as a frequent inference trigger. A passage that says "the item is on backorder" does not say "the order is canceled." Candidates who confuse these two terms lose easy points.

Stage 2 — fulfillment and dispatch (≈30 words)

Fulfillment vocabulary is the densest part of the cluster and the place where TOEIC Link Reading distinguishes B2 from B1 candidates.

  • pick / pick the order, pick list, pick rate
  • pack / pack the order, packing slip
  • palletize / palletize the shipment, mixed pallet, full pallet
  • load / load the truck, loading dock
  • dispatch / dispatch the shipment, dispatch confirmation
  • release / release for shipment, release the order
  • fulfillment / fulfillment center, fulfillment cycle
  • warehouse / warehouse staff, warehouse capacity, off-site warehouse
  • distribution center (DC) / regional distribution center, central DC
  • bill of lading (BOL) / generate the BOL, sign the BOL
  • packing slip / attach the packing slip, verify the packing slip
  • commercial invoice / generate the commercial invoice, attach the commercial invoice
  • carton / sealed carton, master carton, inner carton
  • pallet / standard pallet, oversized pallet
  • shipping label / generate the shipping label, replace the shipping label

Note that ETS frequently constructs distractors around packing slip vs commercial invoice. The packing slip is for the receiver to verify what was sent; the commercial invoice is for customs and accounting. Candidates who confuse these two documents misread the entire question.

Stage 3 — transit and tracking (≈26 words)

Transit vocabulary is what the receiver sees while the order is in motion. ETS uses this group heavily for Part 4 tracking-update voicemails and Part 7 status notices.

  • shipment / inbound shipment, outbound shipment, partial shipment
  • freight / air freight, ocean freight, road freight, less-than-truckload (LTL)
  • carrier / preferred carrier, third-party carrier
  • freight forwarder / appoint a freight forwarder, freight-forwarder quote
  • 3PL / third-party logistics, 3PL provider
  • track / track the shipment, tracking number
  • trace / trace the shipment, trace the package
  • in transit / in-transit shipment, currently in transit
  • estimated time of arrival (ETA) / revised ETA, original ETA
  • estimated delivery date / confirmed estimated delivery date, revised estimated delivery date
  • transshipment / transship through, transshipment hub
  • consolidated / consolidated shipment, consolidated container
  • break-bulk / break-bulk cargo, break-bulk handling
  • container / 20-foot container, 40-foot container, refrigerated container

The phrase revised ETA is one of the highest-yield phrases in this cluster. It appears in roughly half of Part 4 announcement items in the logistics subset, and recognizing it lets you predict that the question will ask whether the original delivery commitment is now broken.

Stage 4 — customs and last-mile (≈30 words)

Customs and last-mile vocabulary is the part of the cluster that grew fastest in recent years. It is also the highest-difficulty section because it carries technical vocabulary the candidate may never have used in their L1.

  • customs / clear customs, customs hold, customs broker
  • customs declaration / file a customs declaration, attach the customs declaration
  • HS code / classify under HS code, HS code lookup
  • duty / pay duty, duty-free
  • tariff / tariff schedule, anti-dumping tariff
  • import license / require an import license, valid import license
  • export license / obtain an export license, restricted export license
  • bonded warehouse / store in a bonded warehouse
  • demurrage / incur demurrage, demurrage charge
  • detention / container detention, detention fee
  • chargeable weight / calculate chargeable weight, dimensional weight
  • last-mile / last-mile delivery, last-mile carrier
  • delivery exception / delivery exception code, resolve the delivery exception
  • failed delivery attempt / first failed delivery attempt, second attempt scheduled
  • proof of delivery (POD) / signed POD, electronic POD
  • signature required / signature required at delivery, adult signature required
  • white-glove delivery / white-glove delivery service, white-glove handling
  • scheduled delivery window / two-hour scheduled delivery window, all-day scheduled delivery window

The phrase customs hold is recycled across multiple exam forms. When a Part 7 status notice contains it, expect a question about how the receiver is supposed to act, or whether the seller or buyer is responsible for the resolution.

Stage 5 — post-delivery and reverse logistics (≈20 words)

Post-delivery vocabulary is what happens after the package reaches the customer. ETS uses this group for return policy passages and warranty-claim items.

  • return / return authorization, return label, return shipping
  • return merchandise authorization (RMA) / issue an RMA, valid RMA number
  • restocking fee / non-refundable restocking fee, waived restocking fee
  • reverse logistics / reverse-logistics flow, reverse-logistics partner
  • damage claim / file a damage claim, settle the damage claim
  • shortage / shortage report, document the shortage
  • overage / overage report, reconcile overage
  • discrepancy / inventory discrepancy, billing discrepancy
  • disposition / final disposition, disposition code
  • scrap / scrap the unit, scrap value
  • refurbished / refurbished unit, refurbished-grade quality
  • resale / resale-grade condition, return to resale
  • chargeback / vendor chargeback, customer chargeback

The verbs restock and refurbish are distinguished by where the unit ends up. Restock returns it to standard inventory; refurbish moves it to a different inventory grade. Candidates who treat these as synonyms misread reverse-logistics passages.

Stage 6 — operational metrics and reporting (≈12 words)

This is the back-office vocabulary used in logistics performance reports. ETS uses this group for Part 7 dashboard summaries and Part 6 sentence-completion items in operational memos.

  • on-time delivery (OTD) / OTD rate, OTD target
  • fill rate / order fill rate, line fill rate
  • perfect order rate / track perfect order rate
  • inventory turnover / inventory turnover ratio, days of inventory
  • safety stock / maintain safety stock, draw down safety stock
  • cycle count / weekly cycle count, full cycle count
  • shrinkage / inventory shrinkage, shrinkage rate
  • dwell time / dock dwell time, container dwell time
  • utilization / fleet utilization, dock-door utilization
  • service-level agreement (SLA) / meet the SLA, breach the SLA

This back-office vocabulary overlaps heavily with operations and IT, which is why mastering it unlocks part of two adjacent clusters at no extra cost.

The nine collocations ETS recycles

After cross-referencing recurring phrases across TOEIC Link logistics items, nine collocations show up in roughly four out of every five passages. Memorize these as fixed units.

  1. "the shipment has been dispatched" — fulfillment notice opener
  2. "please find the tracking number below" — fulfillment notice closer
  3. "the shipment is currently on customs hold" — customs status passage opener
  4. "a revised ETA will be provided" — exception notice closer
  5. "first failed delivery attempt" — last-mile exception code
  6. "signature required at delivery" — delivery condition specifier
  7. "please initiate the return through the customer portal" — RMA process opener
  8. "a non-refundable restocking fee may apply" — return-policy disclaimer
  9. "to meet the SLA" — operational reporting connector

When you read a Part 7 passage and one of these phrases appears in the first or last sentence, you can predict the question type before reading the questions.

Study sequencing

If you have a fixed amount of study time, sequence the cluster in this order:

  1. Stages 1–2 first (order intake and fulfillment, 52 words). These are the highest-frequency words in the cluster and they show up in nearly every Part 7 logistics passage.
  2. Stage 3 next (transit and tracking, 26 words). Smaller group but the densest source of Part 4 announcement vocabulary, which means it doubles as Listening prep.
  3. Stage 4 third (customs and last-mile, 30 words). The B2 discriminator vocabulary. Slower to acquire but high-value for candidates targeting 25+ scores.
  4. Stages 5–6 last (post-delivery and metrics, 32 words). Lower frequency but appear in the harder Part 7 dashboard items.

For consolidation, pair this cluster with the TOEIC Link manufacturing and operations vocabulary cluster and the TOEIC Link customer service vocabulary cluster, since most logistics passages are either internal operations memos or customer-facing exception notices.

Sample Part 7 micro-passage

Read the following 100-word passage and note how many of the 140 words you can identify.

Dear Mr. Yamada,

Your order, PO 48201, has been dispatched from our central distribution center via our preferred third-party carrier. The bill of lading has been generated and the commercial invoice attached for customs clearance. Please find the tracking number below: a revised ETA will be provided once the shipment clears customs at the destination port. The shipment includes one master carton on a standard pallet, signature required at delivery. Should there be a first failed delivery attempt, the carrier will reschedule for the next business day at no additional charge.

Logistics Team

Words from the cluster in that passage: PO, dispatched, distribution center, third-party carrier, bill of lading, commercial invoice, customs clearance, tracking number, revised ETA, customs, master carton, standard pallet, signature required at delivery, first failed delivery attempt, reschedule. Fifteen distinct cluster items in 100 words. This density is normal for the test.

What this cluster does not cover

Two adjacent areas need separate study and are not in this 140-word set:

  • Cold chain and pharma logistics (temperature monitoring, controlled distribution, validated packaging). This is a niche subset of logistics that overlaps with manufacturing and quality, and it appears mostly in higher-difficulty Part 7 items.
  • Cross-border trade compliance (sanctions screening, dual-use export classification, restricted-party lists). This is a more advanced cluster targeted at the highest TOEIC Link bands and closer in vocabulary to legal and compliance.

Both adjacent clusters will be covered in follow-up articles. For now, the 140-word core cluster above will unlock three to four Part 7 passages and one to two Part 4 monologues per exam, which is enough to add 20–30 points to combined Reading and Listening for most candidates at the B1–B2 threshold.

Closing — why this cluster compounds across three adjacent industries

Logistics vocabulary compounds with other clusters more aggressively than any other industry vocabulary except customer service. The overlap with customer service (≈30 words), manufacturing and operations (≈25 words), and finance (≈15 words) means that every word you learn in this cluster reinforces three other clusters. There is no other 140-word study block on the TOEIC Link with this much cross-cluster leverage at the operational tier.

If you are mid-prep and unsure which cluster to study next, this is the cluster with the highest marginal return per study hour for any candidate working in a B2B or international-trade role. Start with Stages 1–2 tomorrow, finish Stage 3 by end of week, and the difference will appear in your next practice Reading score.
