What Data to Provide
- Product details — dimensions (cm), weight (kg) per unit and per carton
- Quantity — total units to ship
- Origin — factory location (city/country)
- Destination — Amazon FBA warehouse country/region
- Timeline — how urgently do you need stock?
- Product value — for duty calculation
Shipping Method Comparison
Sea Freight (FCL / LCL)
| Type | When to Use | Transit Time | Cost Estimate |
|---|---|---|---|
| FCL 20ft | >15 CBM, frequent shipper | 25–35 days | $1,500–$3,000/container |
| FCL 40ft | >28 CBM | 25–35 days | $2,500–$5,000/container |
| LCL | \x3C15 CBM, small shipments | 35–45 days | $80–$150/CBM |
Best for: Large shipments, low-margin products, planned inventory restocks Avoid when: Urgent, small shipment, or product is high value/low volume
Air Freight
| Service | Transit Time | Cost Estimate |
|---|---|---|
| Standard Air | 7–14 days | $4–$8/kg |
| Economy Air | 14–21 days | $2.5–$5/kg |
Chargeable weight = max(actual weight, volumetric weight) Volumetric weight = L × W × H (cm) / 6,000
Best for: New product launches, seasonal restocks, high-value low-weight products Avoid when: Heavy/bulky products, cost is main concern
Express Courier (DHL/FedEx/UPS)
| Service | Transit Time | Cost Estimate |
|---|---|---|
| DHL Express | 3–5 days | $8–$15/kg |
| FedEx International | 3–5 days | $8–$15/kg |
| UPS Worldwide | 3–5 days | $8–$15/kg |
Best for: Urgent stock-outs, samples, \x3C50kg shipments Avoid when: >100kg (air freight becomes cheaper)
Landed Cost Formula
Product Cost (COGS) = Unit cost × Quantity
+ Inbound Freight = Shipping method cost
+ Customs Duty = Product value × Duty rate %
+ VAT / Import Tax = (Product + Freight + Duty) × VAT rate %
+ Customs Broker Fee = $150–$300 flat
+ Port/Handling Charges = $50–$200
+ Inland Delivery (to FBA) = $0.50–$2.00/carton
+ Amazon FBA Inbound Placement = $0.27–$1.58/unit (2024 fee)
─────────────────────────────────────────────────────
Total Landed Cost = Sum of all above
Landed Cost Per Unit = Total ÷ Quantity
Import Duty Rates (US HTS Common Categories)
| Product Category | HS Code Range | US Duty Rate |
|---|---|---|
| Electronics | 8471–8529 | 0–3.7% |
| Clothing/Apparel | 6101–6217 | 12–32% |
| Footwear | 6401–6403 | 20–37.5% |
| Kitchen tools | 7323–7326 | 0–3.9% |
| Toys/Games | 9501–9508 | 0% |
| Sports equipment | 9506 | 4–5.1% |
| Furniture | 9401–9403 | 0–7% |
| Yoga mats/Fitness | 3926/9506 | 4–5.3% |
Note: Section 301 China tariffs add 7.5–25% on many Chinese-origin products. Always verify current rates at USITC.gov.
Shipping Timeline Planner
Work backwards from your target in-stock date:
Target in-stock date: [Date]
- FBA receiving buffer: -7 days
- Port to FBA transit: -3 days
- Customs clearance: -5 days (sea) / -2 days (air)
- Transit time: -30 days (sea) / -10 days (air)
- Export customs/loading: -5 days
- Production lead time: -[X] days
────────────────────────────────────────
Order placement date: [Calculated]
Decision Framework: Which Method to Choose?
| Scenario | Recommended Method |
|---|---|
| First shipment, \x3C200kg | Air freight or Express |
| Regular restock, >500kg, >30 days lead time | Sea LCL |
| Large seller, >15 CBM per shipment | Sea FCL |
| Running out of stock, \x3C2 weeks | Express (DHL/FedEx) |
| High-value, low-weight product | Air freight |
| Low-margin, heavy product | Sea freight only |
| Seasonal launch (e.g., Christmas stock) | Sea: ship by Oct 1 |
Carton Optimization Tips
- Keep carton weight under 23kg (FBA requirement, safety)
- Standard carton size for FBA: 60×40×40cm (1 CBM = 25 cartons)
- Maximize carton fill to minimize LCL costs
- Match master carton quantity to FBA box limits (no more than 150 units/box for standard)
Freight Forwarder Selection Criteria
| Factor | What to Look For |
|---|---|
| Amazon FBA experience | Must know FBA label requirements |
| US customs broker | In-house or established partner |
| Tracking system | Real-time shipment visibility |
| Communication | English-speaking, responsive |
| Price | Get 3+ quotes, compare apples-to-apples |
| Insurance | Cargo insurance included or available |
Recommended: Always get quotes from at least 3 forwarders
Output Format
- Cost Comparison Table — sea vs. air vs. express for your shipment
- Recommended Method — best option with reasoning
- Full Landed Cost Breakdown — every line item to final unit cost
- Timeline — ship-by date based on your target in-stock date
- Red Flags — duty risks, seasonal surcharges, FBA restrictions
Usage Guidance
This skill appears to be what it says: an instruction-only FBA logistics calculator. Before installing, consider: 1) The skill permits use of Bash — if you allow autonomous invocation, the agent could run shell commands (benign for calculations but potentially sensitive if misused). Limit agent privileges or run it in an isolated environment if you’re cautious. 2) The 'save' command is ambiguous — ask or inspect where shipment profiles are stored and whether they contain any sensitive data. 3) The skill does not request any credentials, so don’t provide cloud or account secrets to it. If you need persistent storage or integrations (e.g., saving to S3, Google Drive), prefer explicitly declared, audited integrations rather than implicit file writes.
Capability Assessment
Purpose & Capability
The name/description (FBA logistics cost calculator and shipping optimizer) align with the SKILL.md content: formulas, timelines, shipping method guidance, and interactive commands. No unrelated credentials, binaries, or config paths are requested. Minor mismatch: commands like 'logistics save [shipment]' imply persistence/storage but the skill declares no storage or config path, so it's unclear where saved profiles go.
Instruction Scope
SKILL.md stays inside the logistics domain: it asks for product/origin/destination details and provides formulas and decision guidance. It does not instruct reading unrelated files or exfiltrating data. One operational ambiguity: allowed-tools: Bash is permitted, which could enable arbitrary shell execution if the agent uses it; the instructions themselves do not require reading system files or external secrets.
Install Mechanism
No install spec and no code files (instruction-only). This minimizes on-disk installation risk.
Credentials
The skill requires no environment variables, credentials, or config paths — proportionate for a calculator/guide. It does reference external resources (USITC.gov) for verification, which is appropriate and not demanding of any secrets.
Persistence & Privilege
always:false and default invocation settings are appropriate. The only concern is the conceptual 'save' command without a declared storage location — in practice an agent might write files or attempt to persist data using the Bash tool; consider where such data would be stored and who can access it.
