The price you negotiate with a supplier is not the price you pay to land the goods. Between the factory gate and your warehouse sit a tariff classification, a set of documents, a packaging rule most first-time importers have never heard of, and — depending on what you bought — a dangerous goods question. None of it is complicated, but all of it is unforgiving of improvisation.
This guide covers the sequence in the order it actually matters: classification first, documents second, then the two things that most often delay a first container.
> This is operational guidance for planning, not customs advice. Duty rates and trade measures change; for anything binding, confirm with a licensed customs broker and the official tariff schedule.
What decides your duty: classification first
Everything downstream of classification — the rate, whether additional trade measures apply, whether a permit is needed — follows from one code. Get the code wrong and the rest of your cost model is wrong.
Two things decide it:
- What the product is. A finished candle and a bag of wax are classified differently, and a wax blend may not sit where you expect. Describe the product by its material and function, not by the label on the website.
- Where it is going. The same product can carry different treatment in different markets, so a code that works for one destination does not transfer automatically.
Ask your supplier for the classification they normally use, but treat that as an input, not an answer. The party responsible for the declaration is the importer — you.
HTS 3406 covers candles — check what you actually bought
In the United States, candles, tapers and the like sit under tariff heading 3406, with separate statistical lines inside it. If you are importing finished candles, that is your starting point.
If you are importing raw material instead — soy wax, sand wax pearls, jelly wax — you are not in 3406, and the correct heading depends on the wax type and its presentation. This distinction trips up buyers who assume "candle supplies" import under one code. It does not.
Confirm the current text on the official schedule rather than a resale listing: the US Harmonized Tariff Schedule is published at hts.usitc.gov, and it is revised during the year, so check the edition in force when you ship.
One more layer for Chinese-origin goods: additional trade-remedy measures may apply on top of the base rate, and they are attached to specific subheadings. Whether they apply to your code and your origin is a question for your broker — but it is a question you should ask *before* you agree a landed price with your customer.
Documents you should have before the container is booked
Documents are not paperwork that follows the shipment. They are what allows the shipment to move. Have these ready before booking:
- Commercial invoice — seller, buyer, full description, quantity, unit value, Incoterm, country of origin.
- Packing list — cartons, weights, dimensions, marks. It should match the invoice exactly.
- Bill of lading (sea) or air waybill (air) — issued by the carrier after booking.
- Certificate of origin — required for origin-based duty treatment.
- Batch COA for the material — the quality record for what is actually in the container. If your supplier never issues one, that is a supplier problem, not a paperwork problem.
- Safety data sheets (SDS) — for fragrance oils, dyes and any regulated input.
A file that is missing one of these at the port is a file that generates storage charges. Our guide to the compliance documents explains which document answers which question, because the set is often confused with the COA.
Wood packaging: the ISPM 15 mark
If your goods travel on wooden pallets or in crates, the wood itself is regulated. ISPM 15 is the international standard for treating solid wood packaging to prevent pest transfer, and compliant packaging carries the IPPC mark showing the treatment (heat treatment or fumigation) and the responsible facility.
This is the single most common avoidable delay for first-time importers: the shipment arrives, the pallets carry no mark, and the whole load waits while it is dealt with. Ask your supplier to confirm the packaging is ISPM 15 compliant *and marked*, in writing, before booking. Factories that ship regularly do this as routine — which is one practical difference between a producer and an intermediary, as we set out in the factory versus trading company comparison.
When your shipment becomes dangerous goods
Candle wax in solid form is normally general cargo. Fragrance oils are a different matter.
Flammable liquids are classified by flash point, and materials with a low flash point fall into Class 3 (flammable liquids) for transport. That changes how the material can be flown, what packaging and labelling apply, and what documentation the carrier requires.
There is a moving part worth knowing about: the IATA Dangerous Goods Regulations removed the old entries for aromatic and flavouring liquid extracts (UN 1169 and UN 1197) with effect from 1 January 2025. Fragrance materials that used to travel under those entries now have to be assessed under the current edition of the regulations instead. If you or your forwarder are working from an old classification, that is a delay waiting to happen — ask for the classification to be confirmed against the edition in force.
Practical consequence: if you are shipping fragrance, treat it as a specialist shipment and let your forwarder classify it. If you are shipping wax only, do not let anyone add a routine dangerous-goods surcharge to a product that does not need it.
Air, sea, and what each is for
- Air freight is for samples, urgent replenishment, and small high-value consignments. It is fast and expensive per kilo, and dangerous goods rules bite hardest here.
- Sea freight, full container (FCL), is the normal route for volume. Rates are per container, so filling it is the economics.
- Sea freight, less than container (LCL), suits quantities that do not fill a container, at the cost of consolidation time and handling.
For wax — dense, non-urgent, and bought in volume — sea freight is usually the answer, and the honest advice is that a first order should be sized to make the container worth filling rather than to make the invoice look small.
Incoterms decide who clears customs
The Incoterm in your quotation decides who books freight, who insures, and who is the importer of record.
- FOB (free on board) — you arrange and pay the main carriage and clear import. Most common for buyers who have their own forwarder.
- CIF (cost, insurance, freight) — the seller arranges carriage and insurance to your port; you still clear import.
- DDP (delivered duty paid) — the seller handles everything including import duty. Comfortable, and usually the most expensive way to buy, because you cannot see what the duty and clearance actually cost.
Whatever you choose, write it on the quotation. "Delivery included" is not an Incoterm.
The timeline that avoids storage fees
Work backwards from the date you need the goods:
1. Specification and sample — with the batch COA. This is where specifications get settled, not after production. 2. Order and production — confirm the batch window, because a factory schedules runs. 3. Pre-shipment documents — invoice, packing list, COA, origin certificate, and packaging confirmation. 4. Booking and loading — with shipping marks on the cartons. 5. Transit and clearance — pre-clear before arrival so the container does not sit.
Steps three and five are where money is lost. Both are solved by starting the documentation at the sample stage rather than the shipping stage — the same sequencing we use for RFQs.
Where to verify, not guess
Three sources worth bookmarking:
- hts.usitc.gov — the US tariff schedule, including the revision currently in force.
- cbp.gov — US Customs and Border Protection, for entry requirements and packaging rules.
- Your forwarder and broker — for classification confirmation and any trade measure attached to your subheading.
None of them will tell you what your competitor pays. All of them will stop you from discovering your real landed cost after the container has sailed.
Start the paperwork with the sample
The cheapest import is the one where the documents were ready before anyone asked for them. Request your sample together with its batch COA, ask for ISPM 15 confirmation on the packaging, and get the classification confirmed while the wax is still a sample rather than a container.
